Processed or Ultra-Processed?

The best lasagna I ever ate was home made. Even the pasta! 100 grams durum semolina flour and 1 egg, diligently hand mixed, kneaded, then rolled into thin sheets with this cool little pasta machine I brought back from Rome one year. Pelati, canned whole peeled Italian tomatoes, olive oil, some garlic and onion, fresh basil and parsley, gently boiled down into a traditional marinara sauce. Fresh ricotta cheese. A mixture of ground beef and pork browned and seasoned. Layer by layer all that deliciousness was carefully arranged in my pan and baked to perfection in the oven. It was incredibly delicious! 

My home made masterpiece was a spontaneous event. I don’t even remember following a recipe although I had a general idea of ingredients before I set out. But I’ll never do it again. Why? Because the process took one whole day!

When I serve a lasagna these days, my choices are store prepared or store bought off the shelf. I’ve had good lasagnas, but I’ve never found a replacement that matches the taste of that lasagna I made myself. Not at least until recently …

Rao’s Made for Home, the same folks who produce a wicked good Marinara sauce, has gone into the frozen entrée business and one of their offerings is Meat Lasagna. 

Pre-prepared meal entrées are often disappointing because they are ultra-processed formulations of inferior ingredients intended to displace real food. Convenient yes. Delicious no. Never as good as the dish they intent to replace. But hope springs eternal, especially after a year of pandemic isolation, so I decided to give it a try. 

What a pleasant surprise!

What truly amazed me was the quality of the pasta. The taste and consistency of those sheets of lasagna actually reminded me of that lasagna I made by hand. It’s an amazing accomplishment because Rao’s Made for Home lasagna is a manufactured product, so by definition it’s both an industrial formulation and ultra-processed. Or is it ultra-processed?

INGREDIENTS

The ingredient list reads like a recipe for home made lasagna: Italian Whole Peeled Tomatoes (Tomatoes, Salt, Basil Leaf), Ricotta Cheese, (Milk [Whole & Skim], Vinegar, Salt), Pasta (Durum Semolina), Water, Beef, Mozzarella (Pasteurized Part Skim Milk, Cheese Cultures, Salt, Enzymes), Pork, Romano Cheese (Pasteurized Cow’s Milk, Cheese Cultures, Salt, Enzymes), Onions, Olive Oil, Egg, Salt, Spices, Garlic, Onion Powder, Garlic Powder. 

The ingredients are recognizable. And the label is beyond clean because no additives of any kind are listed. What isn’t on the label is as significant as what is. No modified corn starch, no natural flavor, no carrageenan, no gums. No messy additives to clean up!

The ingredients are top quality. Whole peeled Italian tomatoes are listed instead of tomato paste or purée. Fresh ricotta cheese instead of dry curd cottage cheese. And olive oil instead of canola or soybean oil.

Bronze cut does not appear in the ingredient list but the words can be found on the back of the box on the right panel. “Snuggled between every layer of bronze cut pasta …”. Those words bronze cut pasta are significant and may explain why the Rao’s lasagna reminded me of my hand rolled sheets.

Pasta has been made in Italy since the 13th century, but up until recently it was mixed and cut by hand. Manufacturers today use an industrial process called extrusion. The dough is mixed then forced through a mold or “die” which forms the familiar shapes we find on the grocers shelf: orecchiette, penne, lasagna. Most modern producers coat their dies in Teflon producing a smooth shinny pasta. Using bronze is the traditional method but its use fell out of favor because Teflon is cheaper. 

NUTRITION

Using current nutrient reductionist criteria, lasagna is not a healthy choice. Whether frozen and re-heated, served at the Olive Garden, or prepared at home with hand rolled lasagna sheets and carefully sourced ingredients, lasagna gets classified as “empty calories”. Too many grams of saturated fat and too many milligrams of sodium. 

There are other ways to think about what’s healthy and widen the focus however. Like ingredient quality. Or degree of processing.

TASTE

So why does the Rao’s lasagna remind me of my home made lasagna. Maybe it’s because of the whole peeled tomatoes or the fresh ricotta? Or maybe the bronze cut sheets of lasagna? Or maybe the olive oil? It’s not cold-pressed extra-virgin, but at least the oil is pressed or centrifuged from olives instead of rape seed or soybeans. 

Because taste is 100% subjective, I don’t know if you would like the lasagna as much as I did but two facts are indisputable. The lasagna is made with quality ingredients. And it costs twice as much as its competitors. 

SO IS RAO’S LASAGNA  PROCESSED OR ULTRA-PROCESSED?

There’s an argument to be made for either side. As per this 2019 commentary:  Ultra-processed foods are not ‘real food’. As stated, they are formulations of food substances often modified by chemical processes and then assembled into ready to consume hyper palatable food and drink products using flavours, colours, emulsifiers and a myriad of other cosmetic additives. 

The product is a formulation that is industrially made and mass produced. That’s why the product will taste exactly the same every single time. These are characteristics it has in common with Twinkies, Oreos, and Doritos.

However, the ingredients are real food. I’m being subjective here, but I don’t see the ingredients listed on the label as food substances. Or as Michael Pollan puts it “food-like” substances. Rao’s lasagna uses precisely the ingredients that I would use to make lasagna at home. No additives needed. No flavors, colors, emulsifiers, or any other cosmetic ingredients. Just real food.

I want to classify the product as processed because the taste is clean and the list of ingredients is simple and straightforward. But I can’t ignore the technological sophistication which guarantees that taste will be consistent in every box. So there you have it. Is Rao’s meat lasagna processed or ultra-processed? It all depends …

Bottom line, there are some wrinkles in the NOVA food classification system which will be need to be ironed out.

 

Where’s the Apricot?

My favorite dried apricots are moist, flavorful, sweet, and the color of rusty golden brown. A perfect balance to a handful of dry roasted unsalted nuts.

Dried apricots are whole fruits with the water removed. They are flat, but still recognizable as apricots. Some products, like my favorite KIND bar, list apricots as an ingredient but when you open the package and look for the apricot, all you find is gooey sticky stuff.

That observation inspired this month’s post. Minimally processed versus ultra-processed. My favorite KIND bar versus a handful of dried apricots and nuts.

INGREDIENTS

Minimally processed dried apricots come in two colors. Rusty golden brown and vibrant orange. Most commercial dried apricots have been treated with sulfur dioxide, an additive that lightens the color, softens the texture, and extends shelf life. I prefer the darker color, however. They are harder to find but the taste is more complex and nuanced.

A dried apricot, whether sulphured or un-sulphured, still looks like an apricot. There’s an argument to be made that sulphured apricots are ultra-processed, but un-sulphured apricots clearly meet NOVA guidelines for minimally processed food.

My choice of nuts to compliment the apricots is whole dry roasted unsalted mixed nuts (almonds, walnuts, hazelnuts, pecans, macadamia). Ingredient count is 2 to 6 depending on if you count the mixed nuts as a single ingredient or if you count each kind of nut as a separate ingredient.

My KIND bar has more ingredients. Lots more ingredients. Listed in descending order by weight, I count 13: peanuts, almonds, glucose syrup, honey, apricots, sultana, rice flour, dates, flax seed, soy lecithin, sugar, sea salt. Two of these ingredients count as markers of ultra-processing:  glucose syrup and soy lecithin.

I can also see pieces of nut. But where is the apricot?

All I can see is that sticky gooey stuff holding the nut pieces together. The technical name for the sticky gooey stuff is a slurry and the slurry in my KIND bar must be a combination of purée fruits (apricots, sultanas, dates), added sugars, some starch, and an emulsifier.

Please don’t think I’m picking on the daring of the healthy snacking crew. A KIND bar is one of my favorite ultra-processed foods. When I’m on the run, it’s the first thing I reach for. KIND is also the company that successfully challenged the FDA’s criteria for healthy when the company filed a Citizen Petition back in 2015.

NUTRIENTS

Both the bar and the fruit & nuts are energy dense.

• 4.5 calories per gram for the KIND bar (10% water). An individually wrapped bar that weighs 40 grams clocks in at 180 calories.

• 4.2 calories per gram for a handful of dried un-sulphured apricots & mixed nuts (24% water). One handful of an equivalent weight of dried apricots and mixed nuts clocks in at 168 calories.

Both have similar nutrient profiles. KIND has a few more grams of protein; my handful of apricots and nuts a few more grams of fiber.

Both have an equally favorable fatty acid ratio.

TASTE

The KIND Fruit & Nut bar is dense and chewy. Peanut predominates and I can taste that sweet, fruity slurry. I can’t however taste or see an apricot.

An un-sulphured apricot, a pecan, and a walnut half are also dense but not as chewy or sticky or sweet as the bar. The nuts add crunchy, the sweetness is softer, more nuanced, and clearly apricot.

BOTTOM LINE

The price of a KIND bar varies significantly. The bar I used for taste comparison cost $1.50 at my local supermarket. An equivalent weight for a handful of un-sulfured apricots and mixed nuts is about $1.00.

A handful of fruit and nuts is a great snack to have in your pocket because it requires no refrigeration. But it does require planning and some prep time. KIND bars are ubiquitous and available everywhere.

The taste difference between the bar and a handful of nuts and apricot is dramatic. Which tastes better? That’s a question best left to the eater. Taste is 100% subjective, so the only person you can make that decision for is yourself.

Twinkie Addendum

photo credit | gourmetmetrics

A couple of threads fell into place recently as I continue to explore the NOVA food classification system. And that send me out looking for Twinkies.

The first thread came by accident. I found myself listening to a previously recorded presentation at Google headquarters in California by New York based writer, editor, and publisher Steve Ettlinger. He was in California discussing his book, Twinkie, Deconstructed: My Journey to Discover How the Ingredients Found in Processed Foods Are Grown, Mined (Yes, Mined), and Manipulated into What America Eats. Published in 2007, the book is a fascinating exploration of the multitude of weird, unrecognizable ingredients used in modern food processing. 

The second thread fell into place when I discovered a recipe for homemade Twinkies does actually exists. About a decade ago, Jennifer Schihauser, a NYT journalist, developed a series of articles around the concept “If I make it myself, it’s not junk” and one of her recipes was for making Twinkies at home.

With a Twinkies formulation in one hand and a recipe for a homemade version in the other hand, I can actually do an “apples to apples” comparison between a formulated product and an equivalent homemade version. That was the third thread falling into place. I have what I need to count ingredients / markers of Ultra-Processed food (UPF) and compare nutrition stats. 

I needed to go out looking for Twinkies to get a label, always the best way to get the ingredient list. Product formulations change so the best source of data is always the current product label. Besides, I’ve never tasted a Twinkie so I was curious. I figured I should at least have a bite.

Using the ingredient list from the Twinkie’s wrapper and the Jennifer Schihauser recipe, I was ready to begin.

Running the numbers was easy because I’m in the business of recipe analysis. For guidance on the NOVA food classification system, however, I selected 2019 commentary Ultra-processed foods: what they are and how to identify them to serve as my reference guide.

INGREDIENTS & UPF MARKERS

Flour. Butter. Sugar. Eggs. Those are the primary ingredients listed in the homemade version. All familiar, recognizable ingredients. Besides the basics, the recipe also calls for salt, milk, vanilla, cream of tartar, heavy cream, and Marshmallow Fluff. That’s a total of 11 ingredients. 

The formulated Twinkie is manufactured with mostly unfamiliar ingredients. To my eye, they look like deconstructed fragments. Examples are high fructose corn syrup or dextrose or hydrogenated tallow, mono and diglycerides, polysorbate 60, soy lecithin. 

I counted 7 primary ingredients plus an additional 22 listed on the label as <2% by weight and felt comfortable tagging 18 as UPF markers.

What counts as a marker? As per my NOVA reference document, markers can be 1) “food substances not usually found in the home kitchen like high-fructose corn syrup or 2) “cosmetic additives” like flavors, colors, emulsifiers, sweeteners, or thickeners. Note that salt and sugar get a pass because NOVA classifies them as processed culinary ingredients.

NUTRITION STATS

Both homemade and formulated versions are intense concentrations of fats and sweetness with little positive nutrient benefit. And both versions are calorie dense. 

Nutrients per serving size is the best metric for checking how much you’re actually eating, but comparing nutrients in similar products needs a different metric. My choice for this type of comparison is the calorie density scale which reflects nutrient values by weight. Think of the calorie density scale as a sort unit price for nutrients.

The homemade Twinkie is 3.6 calories per gram. The formulated product is 3.4 calories per gram. To put these calorie density numbers in context, Doritos scores 5.1 on the calorie density scale whereas a Chipotle Beef Burrito will clock in at about 1.8 calories per grams.

Both recipe and formulation have comparable amounts of total fat but homemade Twinkies have a significantly higher concentration of saturated fat. No surprises here. Butter is the only fat called for in the recipe and butter is notoriously high in saturated fatty acids. 

The formulated Twinkies use a combination of animal fat (tallow) and seed oil (cottonseed oil) which results in less saturated fat and more unsaturated fat.

Both recipe and formulation are intensely sweet. Sweeteners in one form or another comprise about 40% by weight. Homemade uses granulated sugar plus some marshmallow fluff. The formulation lists sugar, high fructose corn syrup, and dextrose. 

Sodium is not significant for either version but it’s worth noting there’s more in the formulation than the recipe.

TASTE IS 100% SUBJECTIVE

The final thread fell into place when I tasted the Twinkie. Actually better than I expected but still too sweet for my taste.

WHY BOTHER?

It’s takes many hours to source and study the NOVA research, to count ingredients and identify the markers, and to compare nutrition stats. Here’s why I believe my time was well spent:

  • I learned that nutrients are easier to count than ingredients or UPF markers, especially hard was deciding which additives were “cosmetic” and which were not. Difficult and inconclusive.
  • Simplistic pronouncements by food pundits, corporate marketeers, or social influencers are misleading. NOVA is a sophisticated concept. Selecting a couple of buzz words may sell books or products but does a disservice to consumers.
  • Expanding my NOVA analysis skills is a good investment of time. My sense is we’ll be having more serious discussions about degree of processing in the coming years.

So do I plan to do more apples-to-apples comparisons between a formulation and a recipe? You bet I do.

 

 

Counting ingredients in my favorite Marinara sauce.

Home made Marinara sauce is the best. But life is complicated and having a couple of jars in the pantry ready to go when you need one in a hurry is helpful. The ingredients I use for my home made Marinara are tomatoes (fresh or canned depending on the season), garlic, onions, olive oil, salt, oregano, parsley. That’s 7 ingredients.

My favorite brand is Rao’s. The ingredient list reads almost the same as what I use for home made: whole peeled tomatoes, olive oil, salt, garlic, basil, black pepper, oregano. That’s also 7 ingredients.

Now 7 is greater than 5 and that observation started me thinking about the 5 ingredient rule. 

The 5 ingredient rule refers to the popular marker for identifying ultra-processed foods popularized by Michael Pollan in Food Rules. Defining ultra-processed by counting ingredients sounds unhelpful to my ear but it’s popular with both food journalists and food pundits. And the public seems to accept it because counting to 5 is easy to understand.

And that observation brings me back to my Rao’s Marinara.

With 7 ingredients and no other criteria, Rao’s is ultra-processed. So let me state my position right now for all to hear. If Rao’s must be categorized as ultra-processed, then I’m okay with ultra-processed products on my table.

Next time you’re walking supermarket aisles, check the Marinara sauce. There are hundreds of brands to choose from. Many have simple ingredient lists. Many others have more cluttered ingredient lists. Many brands substitute tomato paste or diced tomatoes for whole peeled tomatoes. So the way I see things, there’s work to be done to distinguish a straightforward product like Rao’s from all the other products on the shelf. 

A quick search on a local supermarket website brings up 75 options ranging in price from cheap to expensive. Not surprisingly, Rao’s is positioned near the top of that price range. All brands have 5 or more ingredients. And that means, if we follow the 5 ingredient rule, all brands of Marinara are ultra-processed.

I spot checked those 75 items and discovered the most notable difference is tomato integrity. Cheaper brands use tomato paste or purée or diced pieces. More expensive brand use whole peeled tomatoes. Tomato integrity is not captured by counting ingredients and it’s crucial to both taste and texture.

 While all brands exceed the 5 ingredient rule, most were comparatively additive free. Citric acid and calcium carbonate made frequent appearances along with preservatives, thickeners, or sweeteners making cameo appearances. Citric acid is an acidity regulator and calcium carbonate is a firming agent. Both these additives are ubiquitous on canned tomatoes whether the tomatoes are peeled and whole, chopped, diced, or puréed. 

Two other additives, salt and sugar, are listed as both nutrients on the nutrition facts label and again as ingredients on the ingredient list.

It seems ridiculous to my simplistic mind to put all Mariana sauces in the ultra-processed category without out further differentiation. So I’m asking myself, how would I break that category down? If I ruled the world, here’s where I would start.

First, whole tomatoes are preferable to chopped or diced or puréed tomatoes. That observation is probably related to the food matrix, a new concept in nutrition research currently in initial stages of investigation. Much too complex for my simplistic mind, so let me stay with those visual observable differences that both of us can see. In the case of the Marinara, the closer the tomato is to a whole tomato the better.

Second, less additives are preferable to more additives. I’m not talking here about the “clean” label movement. There’s a dirty little secret behind the clean label movement as explored in an excellent article by Nadia Berenstein. If you haven’t read it yet, take a look now. 

Additives are used by processors for many good reasons. Eliminating them before understanding why the manufacturer used an additive in the first place is not good practice. Additives are however legitimate markers of processed and ultra-processed products. Personally, I’m not concerned about their safety because I trust the FDA to do a good job. My decision to go with the fewer the better is based on taste and texture. Using the whole intact tomato just tastes better to me. More flavor. Better texture.

Third, nutrients remain important. Reducing healthy down to a couple of nutrients is insane. But it’s equally insane to eat as if nutrients don’t matter. Personally, I always check for salt, not so much for health reasons but because it’s been my observation manufacturers use salt in place of better quality ingredients so the product can be sold at a cheaper price.

Rao’s has a lower sodium concentration than many less expensive brands and the only sugars are the natural sugars present in all tomatoes.  The whole peeled tomatoes retain good flavor and contribute their natural sugars so no masking is required.

Now if only I ruled the world …

What to do when healthy and taste collide.

Pictured above are two winter squashes. Two acorn squash and one sweet dumpling squash picked up recently from my local farmers market. Beautiful, incredibly healthy, and for me at least inedible.

Fall is the season for so many good healthy vegetables. There’s the brassica family. Late season storage carrots. And squashes like butternut, spaghetti, pumpkin, and acorn.

But I have a problem. Squashes make me gag. Not all squashes, just winter squashes. Spaghetti squash. Butternut squash. Acorn squash. Hubbard squash. Exotic squashes like Calabasa. Even familiar squashes like pumpkin which is, despite its notoriety as both a police flavor and a dessert, still a member of the winter squash family.

All vegetables are healthy but some vegetables are more healthy than others. Pigment color is a good marker for phytonutrients. Red, yellow, and orange fruits and vegetable are rich in carotinoids. And winter squash is nothing if it’s not deep orange.

So I tried on many occasions to find some way to prepare winter squashes but never succeeded.

A couple years ago, I put on my creative cooking cap and came up with a good solution. Every Thanksgiving I make pumpkin pie. So I got to thinking, what would happen if I used the same amount of steamed local squash for canned pumpkin?

My solution worked. Those little squashes make excellent squash pies. Squash purée, eggs, sugar, milk, butter, vanilla, cinnamon, nutmeg, just a pinch of salt, an olive oil crust. Et voilá!

As my zealous colleagues are forever reminding us, squash pie is not as healthy as steamed squash. Too much fat and too much sugar. However my squash pie is fresh baked, I can eat it without gagging, and not a single squash will go to waste.

Fat. Sugar. Salt. In the hands of a creative and gifted cook, all three work kitchen magic. Trust me, the food manufacturing industry is not unaware of this culinary fact. For industrially processed or ultra-processed foods, overuse can be problematic.

But those of us who cook or bake at home are not industrialists. Nor are we flavor technologists formulating the next product for mass consumption.

We have the luxury of making our own discretionary judgement calls. And that’s why as both cook and RDN I encourage home cooks to make use of the magic. Fat, sugar, and salt make freshly prepared food taste even better.

It’s really is okay as home cooks to make those discretionary decisions.

Quarantine Cooking and Emotional Eating

“Like most humans, I am hungry. Our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others. So it happens that when I write of hunger, I am really writing about love and the hunger for it…” 

― M.F.K. Fisher, The Gastronomical Me, 1943

Those words were written nearly 80 years ago. Now fast forward to today. 

The corona virus has arrived in New York and we’ve been staying at home for over a month. Shopping the center of the isle is back in fashion. My colleagues are writing helpful posts about managing cravings and focusing on healthier options. Comfort food sales are booming.

The pandemic has entered our lives and our kitchens. We are all hoping a new normal will be as bright and sunny as my lovely flowers, but no one knows for sure. Our future is uncertain.

Staying home, being unemployed, home schooling your kids – whatever your current situation is, I am sure that you’re as hungry for food and love and security as I am. 

About a decade ago, I was the dietitian tasked with setting up the nutrition component for a bariatric wellness program to help overweight folks loose enough weight to qualify for bariatric surgery. Most of my understanding of emotional eating comes from the work I did for that program. 

My approach to promote self awareness was the self-care acronym HALT. I did private one on one sessions and participated in weekly group sessions with a physical therapist, social worker, psychologist, and me an RDN. 

HALT for those not familiar with the acronym = Hungry, Angry, Lonely, Tired.

For the last couple of weeks, those words are reflecting how many of my fellow New Yorkers are feeling. Those words reflect how I am feeling too. If I turn to food for comfort, does that make me an emotional eater? Because if it does, I am guilty as charged and need treatment. 

So what is that treatment? Redirect cravings, identify triggers, and separate them from food.

I’m not sure that treatment works today and am obsessed with the observation, made nearly 80 years ago, that food and security and love are inseparable.

Before the corona virus arrived, dietitians like me and my colleagues characterized emotional eating as the enemy. Today we are dealing with a new enemy and as we are learning, this virus is a serious threat to our security and well being.

And I am having a moment of significant personal doubt.

Maybe we’ve been going at this emotional eating thing from the wrong direction. Maybe we humans are not as good as we thought we were at separating our hearts from our stomachs.

Before I became a dietitian, I was a home cook. My Tantôt Brieux taught me to make crèpe at the age of 5 and I’ve been hooked ever since. From milking a cow in British Columbia to private cooking for a couple of years in Paris, culinary curiosity and culinary passion have formed my approach to food.

During the last month that I’ve been staying at home, I’ve cooked every night. I’ve spent more time at table with people I love and care for and experienced food and love and security coexisting in positive balance.

No one knows yet what will evolve over the next couple of months or years. The virus will claim its victims. The world may or may not fall into economic recession. Social distancing will likely remain at least for a year or so. Life will go on.

But I am seriously questioning the conventional approach to emotional eating.

Rethinking exactly how we do that is best left to psychologists but let me say this to my fellow dietitians. 

Let’s not be too hasty to reduce hunger down to the physiological need for fuel and nutrients. And let’s not be too quick to assume those who seek comfort during stressful times need tips and treatment plans. 

Reducing healthy down to a couple of nutrients is insane. 

Reducing emotional eating down to triggers and cravings may be equally insane.

Looking at meat through rose colored glasses.

Plant-based is in. Red meat is out. 

Momentum has been building for more plants over the last decade but this year looks like the year plant-based will go mainstream. As more climate related  catastrophes are attributed to a carnivorous lifestyle, darker and more ominous predictions regarding the evils of meat eating will likely continue through 2020. Penance for our sinful climate ways. 

There’s nothing new about the assault on red meat. The first official iteration was nutrient focused and appeared in 1980 with the publication of our first set of dietary guidelines. Guideline #3 reads “Avoid too much Fat, Saturated Fat, and Cholesterol”. Or as the phrase has evolved over the decades, choose lean meat.

Recently, however, red meat has been targeted for different reasons. Environmental and animals rights activists have joined forces to condemn red meat as climate unfriendly and inhumane. These activists are a small percentage of the population but their collective voice is shrill and aggressive. Both groups promote a plant-based plate.

So you may be wondering what inspired a flexitarian like me to put on rose colored glasses and take a peek at red meat in the first place.

It all started with NOVA, a new kind of food classification system, developed about a decade ago in Brazil by a group of academics, that groups foods by degree of processing instead of by nutrients. Foods look remarkably different viewed through a NOVA lens. Especially meat. 

By dividing food into four groups, NOVA allows a single food to be viewed from four distinct perspectives depending on the degree of processing.

Freshly slaughtered and chilled meat is considered minimally processed. Contrary to the prevailing nutrient based perspective, the NOVA classification has a place for meat on the plate independent of fat content. Freshly slaughtered and chilled meat can keep company with other minimally processed foods like fresh fruit and vegetables, nuts and legumes. Wow! That is what I call a revolutionary thought.

The second NOVA group is for processed culinary ingredients like salt, sugar, and oils. Included in this group are traditional animal based fats like butter and lard.

Meats become processed when they are preserved using traditional  techniques like salting, drying, curing, or smoking. NOVA does recommend restraint, but acknowledges the deliciousness of traditional preparations. Examples of traditional processed red meats include corned beef, jerky, prosciutto, dry cured Virginia hams. Other equally delicious non-plant members of this processed foods group are salt cod, smoked salmon, canned fish.

To be classified as ultra-processed, the fourth NOVA group, red meat needs to be pre-prepared, re-formulated, or modified. Examples of ultra-processed meat products are frozen pepperoni pizza, fast food burgers, deli cold cuts, reconstituted meat products like hot dogs, LFTB (lean finely textured beef). 

Making a pizza at home using fresh ingredients and traditionally cured cheese or sausage is classified as processed. Prepackaged frozen pizza manufactured and marketed for convenience gets the ultra-processed classification. 

There’s plenty of controversy surrounding the NOVA classification system.  The groups are squishy and subjective. Lines of demarcation are not clearly defined. Many of my fellow analysts, used to working with thousands of precise nutrient based food codes, dismiss NOVA as unprofessional. Their dismissal is understandable.

So why bother taking a peek you may be asking? Because food is so very much more than the sum of its nutrient parts and over the last 40 years we’ve all been conditioned to look at food through a narrow precisely defined reductionist lens. 

Changing focus and looking through the NOVA lens let’s us take a step back. And by taking a step back from the plate, we get a different perspective. It’s easier to see the food and harder to scrutinize nutrients. Even a flexitarian like me has come to appreciate meat in new ways. Remember, it’s just a peek.

Rethinking Healthy

photo credit | gourmetmetrics

Here’s the menu for a delicious, somewhat indulgent celebration meal I shared with family and friends in December. 

The meal reflects my kind of healthy. At least my kind of healthy before I decided to become a dietitian and learned how to measure healthy in grams of fat.

Over the last three decades we’ve been taught that palatability and healthy are polar opposites. Stealth health is a term still used today with regard to food. In other words, many people still believe that if food is obviously healthy, it’s not to be trusted.

That polar divide dates back to the 1990s. Research was going on prior to that date linking dietary fat to heart issues, but implementation didn’t happen until 1990.

That was the year congress passed the NLEA (Nutrition Labeling and Education Act). I was totally unaware that anything important had happened when I started my nutrition studies in 1993, the same year the Nutrition Facts Label appeared on packaged products. Buried under layers of regulatory cement, the new law contained austere nutrient-based criteria for healthy. Initially, the criteria were only applicable to packaged goods but by the end of the decade, the damage was done and the word healthy was successfully redefined as low fat.

The only items on my Christmas menu that qualify as healthy using these austere criteria are the baguette, the steamed rice, and the clementines. 

Low-fat is healthy dominated the first decade of this century. According to NBC news, when a group of researchers set out to understand the views of executives at major U.S. restaurant chains regarding the addition of healthy options to their menus, they were able to determine why by ensuring anonymity to the executive’s interview.

“If we put something on the menu and say it’s healthy, it’s the kiss of death,” one executive told the researchers.

The kiss of death was not limited to restaurant food. The first time I ran numbers on a mix of fresh mesclun with vinaigrette dressing, I discovered to my horror that my salad couldn’t qualify as healthy either. Too much fat. And too much saturated fat.  Olive oil has a higher fraction of saturated fatty acids than walnut or avocado or some of the other wonderful oils that can be used for a vinaigrette. In other words, my salad was even more unhealthy because I used olive oil.

Healthy as low-fat remained set in regulatory cement for 25 years. In 2015, however, something happened. That was the year the FDA sent a warning letter to the manufacturer of KIND BARS.

Most of the errors were minor technicalities except for one major misbranding error. The FDA requested that the manufacturer remove the word healthy from the label. The bars identified were made with nuts and because nuts are high in fat, the gram values exceeded those austere criteria set back in 1990.

KIND BARS complied but decided to file a citizen’s petition asking the FDA to re-evaluate. And the FDA agreed. The agency acknowledged the science related to recommendations for intake of dietary fats had evolved and, as per a 2016 guidance document, stated its intention to exercise enforcement discretion on an interim basis shifting the focus away from limiting total fat to encouraging unsaturated fats.

Et voilà. With the stroke of a bureaucratic pen, my menu got healthier. The menu as a whole just meets the current level 35% calories from total fat and my green pea soup, green beans, and rapini now meet this interim FDA criteria for healthy.

About the same time that the FDA published their interim guidance, a group of academic researchers working out of a university in Brazil published a document that took a completely different approach to healthy. 

Nutrition researchers and policy professionals in this country are used to breaking foods down into smaller and smaller components. Researchers have worked hard to develop hundreds of thousands food codes. Using these food codes, policy professionals can manipulate foods precisely and accurately in every conceivable combination of nutrients, micronutrients, or any other component.

The Brazilian academics reversed the process. They took a step back and developed a system that consolidated foods into only 4 groups: Unprocessed / Minimally Processed; Processed Culinary Ingredients; Processed Foods; Ultra-processed Foods. They called this food classification system NOVA.

Most chefs, home cooks, and food writers relate immediately to NOVA. Working with intact foods every day and thinking about food as a whole comes easy. A whole onion. A whole egg. A whole piece of Clothbound Cheddar.

My dietitian colleagues struggle with NOVA because they have been trained to think about food differently.

Dietitians are taught to think about food as nutrients. Onions are low in calories and contain no fat. Eggs are high in cholesterol. And even an artisan hand crafted cheese is high in saturated fat. In their view, NOVA seems crude, simplistic, and downright unprofessional.

Sometimes I feel like I’m caught between two coasts. I understand why NOVA upsets my zealous colleagues but I love the approach. 

And I love looking at my menu through the NOVA lens. Carefully sourced fresh ingredients. Enough salt, sugar, and fat to ensure palatability. Lots of freshly cooked vegetables and fresh fruit.

Here’s how my menu breaks down. All aromatics (onion, celery, carrot), garlic, fresh herbs, rapini, green beans, and clementines are obviously raw, minimally processed and belong in Group 1. Not so obvious foods included in Group 1 would be lamb shanks, spices, dried split peas, whole milk plain yogurt (pie crust), fresh egg (pumpkin filling), basmati rice, and refined wheat flour.

Olive oil, salt, butter (pumpkin filling), and sugar are classified in Group 2 as processed culinary ingredients. Canned whole tomato, canned pumpkin, and Bordeaux rouge are classified as processed foods and placed in Group 3. Only the mass-produced packaged baguette, the prosciutto, and the Armagnac are candidates for ultra-processed or Group 4.

And I’ve ended up coming full circle in my belief about healthy. It’s not that nutrients aren’t important. Nutrients are very important. But in the process of drilling down deeper and deeper, something basic has been forgotten. Let’s hope that something basic has not been lost.

Looking at the plate through a NOVA lens is a gentle reminder that food is more than the sum of its nutrient parts. And that palatability and healthy don’t have to be polar opposites.

What section of the supermarket do plant based meats belong in?

The food scene is changing fast. Plant-based products have arrived and they are disruptive. They don’t fit in the usual slots. It’s not the first time rapid change has disrupted our food supply and it probably won’t be the last, but each time a disruption occurs, our sense of normal needs adjusting.

I posed this question in a couple of forums. Where should a supermarket put a product that is engineered to taste like ground beef but manufactured from pulverized plants and here’s what came back.

EMOTION OUTBURSTS

Plant-based meat analogs evoke passion ranging from evangelical ecstasy to visceral derision.

For true believers, the promise of phasing out livestock production is an absolute good for our health, the planet, sustainability, and the welfare of animals. For many others and for a variety of reasons, replacing real meat with fake meat is misguided. One particularly caustic commentator suggested putting the product in the pet food section because the texture of pulverized plants is the same as canned dog food.

PRAGMATIC SUGGESTIONS

The vegan/vegetarian section would be a logical place and that was the section I checked first. Nothing new. No faux burgers. Just the usual collection of traditional veggie burgers.

Meat analogs can’t go in the organic food section, at lease now yet. The first generation meat analogs don’t meet the USDA organic criteria. One brand even proudly lists the use of two genetically engineered components.

A section dedicated to sustainability might be a candidate for meat analogs. Climate change activists believe red meat is bad for the planet and ruminants like beef and dairy cattle are a big contributor to global warming. But that position is controversial and other groups, especially the regenerative agriculturists, disagree.

Business decisions get made based on many factors and it appears manufacturers have pushed hard to get their meat analogues into the meat department. And that’s exactly where I found the package. Beyond Meat Burgers were right next to the grass-fed burgers in the frozen meat section.

FOOD 2.0

Food 2.0 was the most creative response I received. As technology continues to disrupt the food section, supermarkets will respond as best they can. Food 2.0 is as good as any catch word to describe the brave new world of food tech that we have just entered. The FDA has cleared both major meat analog manufacturers for retail sale and that means a tsunami is about to hit the supermarket floor.

Many of my fellow dietitians have concerns about the healthiness of meat analogs because they are highly processed. I share that concern but to date there’s no good evidence that ultra-processing per se is unhealthy. Lots of speculations and gut feelings but no hard evidence except for one study published this year which established a correlation between a diet of ultra-processed foods and weight gain.

So what should we do while we wait for more evidence?

My plan is moderation. I’m okay with a meat analog from time to time, but my gut isn’t used to high tech food and I see no reason to change right now. So for the time being, the proteins you will find on my plate most days will be lentils and chickpeas and 100% grass-fed beef.

Looks to me like my KIND bar is ultra-processed.

A couple of weeks ago, the word ultra-processed made national headlines when a well done study concluded that ultra-processed food promotes weight gain while unprocessed food does not. This one I said to myself needs further investigation.

After reading the complete study, I linked to another site for clarification on what foods are ultra-processed and ended up at NOVA. There I learned about a Brazilian academic Carlos Monteiro and his novel food classification system NOVA. Links to both study and NOVA provided at the end of the post.

NOVA divides foods into four groups and characterizes ultra-processed foods as follows:

“The fourth NOVA group is ultra-processed food and drink products. These are industrial formulations typically with five or more and usually many ingredients. Such ingredients often include those also used in processed foods, such as sugar, oils, fats, salt, anti-oxidants, stabilizers, and preservatives. Ingredients only found in ultra-processed products include substances not commonly used in culinary preparations, and additives whose purpose is to imitate sensory qualities of group 1 foods or of culinary preparations of these foods, or to disguise undesirable sensory qualities of the final product. Group 1 foods are a small proportion of or are even absent from ultra-processed products.”

Then I went to my pantry hoping to find something vaguely resembling that verbose awkward prose. I didn’t find much until I remembered my KIND bars. I always keep at least one in my pocketbook for emergencies. I’m partial to the apricot almond, so I looked in my pocketbook and there was a KIND bar wrapped and ready to go. The ingredient list is printed on the wrapper: almonds, coconut, apricots, glucose syrup, honey, chicory root fiber, rice flour, soy lecithin, sugar, sea salt.

With the ingredient list in one hand and that prose description in the other, I rolled up my sleeves and got to work. Words in boldface refer back to NOVA. Ingredients are numbered in descending order.

#1 almonds, #2 coconut, #3 apricots are familiar foods. I can see the almond pieces and perhaps the coconut shreds in my KIND bar so we’ll call them intact. I don’t see any apricot pieces however. Maybe apricot purée?

#4 glucose syrup, #5 honey, and #9 sugar are sugar.

#6 chicory root fiber is the name manufacturers give to inulin for labeling purposes. Chicory root is an intact food. It looks like a short fat shaggy cream colored carrot with long brown hairs. Inulin is a white powder which is extracted and refined from the root and is considered an isolated non-digestible carbohydrates by the FDA. Manufacturers can count inulin as a fiber on the nutrition facts label. Inulin is not commonly used in culinary preparations, although you can order inulin as a supplement online or buy it off the supplement shelf in a health food store.

#7 rice flour is a stabilizer

#8 soy lecithin is an emulsifier (not referenced above but found in other descriptions of NOVA)

#10 sea salt is salt

So is my KIND bar ultra-processed? It certainly looks that way to my analytic eye. Of the 10 ingredients counted, 7 tract back to NOVA.

Does it matter? Now that’s the tricky question. And over the next couple of years, many smart, knowledgeable researchers are going to be working hard trying to figure out the answer to that question.

Pictured next to the KIND bar is an equivalent weight of dry unsulfured apricots and almonds which I also keep in my pantry. Just two ingredients. Clearly not ultra-processed. Taste is 100% subjective and my preference is the simpler version of fruit and nuts. But when I’m hungry enough to just need calories, the KIND bar is what I reach for.

Here’s a link to the study and a link to NOVA.
