By Ashok Vasudevan Scientific American is one of my favorite magazines- it educates, informs and occasionally even entertains. The September 2013 special issue on Food is quite broad in its appeal and touches on a host of issues including food science, food processing and even food politics. The editorial “Fight the GM Food Scare” says “mandatory labels for genetically modified foods are a bad idea”. As a food entrepreneur, an academic and a student of agriculture; I have been siting on the GMO fence, not clear on how corporates and governments must react. So this issue of Scientific American for me was very timely. The editorial helped me make up my mind. They are wrong. Here’s why. 

“The issue is in no way simple”, it stated in the first paragraph. Such an editorial beginning promised deep analysis, but soon disappointed. It made a weak argument against GMO labeling and a strong one in support of genetic crops. The premise is that if you support genetic research you must oppose labeling. This is simplistic. “Instead of providing people with useful information, mandatory GMO labels would only intensify the misconception” This seems to be the crux of their argument! A popular science magazine’s responsibility is to explain complex concepts simply and minimize misconceptions and not deliberately keep people in the dark. It is true, many of us don’t understand our calories come from carbohydrates, proteins and fats, let alone comprehend the difference between poly and unsaturated fats. So do we now object to FDA nutritional labeling because confused consumers will make bad food decisions? They then move to support genetics by claiming we’ve been: “Tinkering with our food’s DNA since the dawn of Agriculture”. There is a fundamental difference in plant breeding between mutation, hybridization, tissue culture and GMO, particularly as they pertain to labeling laws. Prop 37 in California had reasonably tight language that requires that to be labeled GMO genetic material has to be changed through DNA injection or cell fusion that breaches a “taxonomic family”. Effectively, hybrid varieties of crops are not GMO. For a scientific journal to not point this out, is tantamount to intensifying misconception. “Today it is virtually impossible to find GMOs in European supermarkets”, the article bemoans, making us believe the hapless Europeans have no high quality food choices! Europe mandated GMO labeling almost 15 years ago. Today Europeans are significantly healthier and leaner than Americans and their supermarkets have great products.  I was shocked to learn that today ~70 percent of processed foods in the US contain GM ingredients. Yet, we debate whether GMO labeling is needed. Honestly, what would we rather have? A 70% certainty of GMO foods for dinner, a near 100% certainty of non-GMO or that ignorance is bliss? “Because conventional crops often require more water and pesticides than GMOs do, the former are usually more expensive”. Here is another dubious argument that is alarmist and trifle ignorant. Alarmist because of its tone and ignorant about how discerning, farmers really are. The brutal truth is agri-companies have no interest in selling GMO crops that don’t need chemicals. Monsanto and Syngenta are mere poster children and they are not alone. “The GMO-fearing can seek out ‘100% organic’ products.” So why label, they ask. This sounds petulant and childish. So why not make the reverse argument, i.e. support GMO labeling and let “value-seekers simply buy cheaper products”! Maybe the truth is they want no food labeling – be it GMO, organic or nutritional. So what if consumers don’t know. At least they won’t misunderstand! The editorial reinforces support for genetic crops by referencing a seven-year study in India about GMO crops that gave farmers “a 24% increase in yield and a 50% increase in profit”. It fails to mention this study was not on a food crop but on Bt Cotton (owned by Monsanto) and while results were promising, they have not been replicated elsewhere. Or that the farmers in the study used more chemicals than normal and not less. A Govt. empowered panel is investigating these results and their report is imminent.  “Green peace and other anti-GMO organizations have used misinformation and hysteria to delay the introduction of Golden Rice in Philippines, India and China”. Golden rice is instructive. Developed by the International Rice Research Institute (IRRI) in the Philippines and now owned by Syngenta, it supposedly produces beta-carotene that helps prevent blindness. It is a GMO that has broken a species barrier. It comes impregnated by genes from corn and bacterium. But expecting governments to approve this, using the argument that it is generally recognized as safe (GRAS standards) is not setting the bar high enough. I have met with literally thousands of farmers in my years in the Agri-business and I know that if they believed GMO crops would use less water and pesticides (and by the way, prevent blindness in their children) there would be a stampede in their rush to GMOfy and they would literally overturn governments if policy and laws stood in their way. Do the editors really think that the Governments in China, Philippines and India don’t want to prevent blindness in 500,000 children annually by simply waving the Golden Rice wand? Or they want to keep their farmers poor? Seriously?  Concerns about GMO foods need to be heeded. Its impact has not been fully studied or understood. We are still in the discovery phase and the road to iteration, development and documentation is long and arduous.  Supporting GMO labeling need not mean opposing genetic research. Eventually both sides will win this battle. Genetic manipulation seems embedded in our evolutionary gene and the future is likely to be filled with genetically modified organisms as science improves and corporations become more responsible. Equally, GMO labeling will continue to evolve as consumers become more aware and governments more responsive. For now a tentative start in GMO labeling is better than keeping 300 million consumers in the dark. That’s not what a free society does. We should embrace knowledge-sharing and notshun it based on unfounded fears.

PROCESSED FOODS OR PREPARED FOODS?

/*! elementor - v3.16.0 - 20-09-2023 */ .elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=".svg"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}


By Ashok Vasudevan Words are beautiful couriers of meaning. A single word can invoke a smile, ignite love, whet our appetite and even make food taste delicious – all at the same time. Just as easily, they can engender bias- either when used without discrimination or when received with suspicion. Words can transform behavior and when misunderstood, cost money. Lots of it. Not just for individuals, but for families, communities and societies at large. 
Let me illustrate this further by choosing some words du jour in the food industry. An increasing base of health conscious consumers react as one to words such as carbohydrates  (bad),  protein (good), fiber (good), local (good), GMO (bad), natural (good), organic (good), processed (bad) and so on. You get my drift. 

Right now I’d like to set the record straight on one of those words. “Processed“ foods are getting a pounding (mostly deserved) by the media and consumers alike. We are also witnessing increased government activism as cities and states hope to improve public health by regulating their sales.

So what are processed foods and what seems to be the problem?

 Lets start with some nutrition basics. Proteins, Fats and Carbohydrates, constitute the macronutrients in food. Fats & proteins are crucial for building tissues, and physical insulation in our bodies. Carbs are the fuel that provides the necessary energy for the human body that account for normal functions such as heartbeat, digestion, walking, eating, etc. Effectively, more than 60% of the all the energy our body needs comes from carbohydrates. And almost all carbs (99%) we eat come from fruits, vegetables and grains[i]. (Meats contain virtually no carbs.) When we eat whole grains, fruits, and vegetables, our body receives life-sustaining forms of “complex” carbohydrates. These complex carbs also contain fiber, vitamins and minerals- the micronutrients. . While fiber itself is not digested, it plays a vital role in the digestive process. Complex carbs take time to digest as they are broken down methodically to simple carbs, which finally get absorbed as glucose in our blood stream. To understand processed foods also requires us to understand the difference between simple and complex carbohydrates[ii]. Simple carbohydrates are basically simple sugars with virtually no nutritional value and hence it is best to limit their consumption. Examples of simple carbs include sugar, glucose, chocolate, jam, carbonated soft drinks, fruit juice, honey, crackers etc. Most fruits, and milk are also simple carbs though clearly, some of them are good for you.  We can find complex carbs in whole grains, (like brown rice, quinoa, Amaranth, millets, whole wheat), most vegetables (lettuce heads and mushrooms are some exceptions with no complex carbs) and legumes (peas, peanuts, beans, lentils etc.).[iii] In a sentence, they are good for you. So, why is this related to processed foods industry and why the drubbing? I am calling it their “subtract, add, transform” problem.

First they subtract. Vegetables, grains and legumes are stripped off their complex carbs, fibers, minerals and vitamins when they are treated or “processed” to produce easily digested, “sugary” foods. Examples of subtraction abound and include some of our favorites, like white rice (brown rice minus bran), white bread (whole wheat grain minus bran minus wheat germ, then baked), refined flour (whole grain minus bran, then pounded), cream of wheat (whole wheat minus bran minus germ, then coarse ground).   Second, they add a long list of additives including colors, flavors, enhancers, binders, food chemicals, stabilizers and preservatives, to make a perfectly simple recipe look like an inorganic chemistry textbook. We all go shopping for such products everyday. We come across breads that contain high fructose corn syrup and bromates, juices with sodium benzoate and potassium citrate, jams with sodium diacetate and even some butter with added colors and flavors! Finally, they transform. Claiming innovation we bring forming, processing and preservation technologies to create new products and claim to enhance taste, nutrition and convenience.  Then they back-pedal and introduce variants that are less harmful hoping consumers feel less guilt (e.g. low fat, low sodium, diet versions etc.). They then fortify with iron, omega-3, anti-oxidants and calcium after stripping them from the original raw materials in the first place! 

Ingredients statements in products we buy are as important (if not more) than even the nutrition label.  Here is one example of ingredients in a rice product available in stores nationwide:

             Long Grain & Wild Rice


If you see names of ingredients you don’t recognize, cannot pronounce or if it reminds you of your chemistry class, you know you are dealing with processed foods. I don’t mean to suggest most food companies are irresponsible or that they don’t have the consumers’ health & wellness at heart. Quite a few do and their brands have outpaced the growth of traditional companies over the past decade. Look around the world to see the number of small food companies that have emerged on the platform of sustainability, natural, and organic. These companies, don’t process food. They prepare it like we might, at home. They use natural and organic ingredients, whole vegetables, whole grains, and legumes.  These companies prepare these foods in the kitchens of their factories and not process them in the shop floor of their manufacturing facility. They don’t subtract, add, or transform. They cook.  Here’s an example of ingredients in another rice product that has recognizable ingredients: Water, Brown Rice, Sunflower Oil! 

These companies have understood that consumers will seek and find foods that combine great taste, health & wellness and real convenience. This is a holistic way of life that consumers have chosen and its here to stay.
To these companies I think words are important. Sustainability to them means sustaining the health of the planet, health of their consumers and the health of the company. Such companies and their consumers know the difference between processed foods and prepared foods.

By Ashok Vasudevan It is sometimes comforting to know that you have struck a balance in an argument and are able to see the other 2 extremes dispassionately, even though you disagree with both positions to some measure. And when informed public opinion is supportive of your position, your sense of wellbeing is further enhanced. You feel “balanced” at this center of gravity. But in the real world this is easier said than done. Imagine trying to stay balanced in the center of a seesaw. This exercise may be good to strengthen your core but it is not a position you can sustain. Just try it. Now, repeat the exercise by placing 2 “extremists” at the ends of the seesaw. A new balance of power emerges and you feel steadier. In a philosophical sense it is almost as if you need these extremes just to stay centered. That is exactly the balance the new exhibition “Our Global Kitchen: Food, Nature, Culture“ currently running at the American Museum of Natural History in New York is trying to achieve.  It takes us on a fascinating and disturbing journey of the world’s oldest and largest industry (agriculture) through a light prism of history, geography, economics, evolution, science, technology and cuisinology. No easy feat. While its grasp may be less than its reach, it highlights issues that are being debated in the public domain across the disciplines mentioned. In so doing, it does not opine or attempt to compromise. Nor does it try to find common ground. But it presents facts and perspectives that make you appreciate the extremes and hopefully carve out your own positions on issues ranging from cultivation, vegetarianism, food preservation, processing, biotechnology and perhaps even GMO. Given the serious social debate on these issues, the timing of this exhibition is uncanny.

Here are a few interesting nuggets from the exhibition that will make you wonder, but may or may not change your mind. 

  • About 870 million people (one in eight humans) in the world were hungry last year and yet 35%  of all crops grown are for animal feeds and not for human consumption.
  • To make it worse, 30% of what is grown for humans does not get eaten due to wastage. What we throw out in the garbage at home is only the last stop in a long global assembly line of value addition from farming, harvesting, transporting, processing, retailing, cooking and finally garbaging. This cumulative waste is a staggering 1.4 billion tons annually.
  • Now lets talk about animal feeds. The story is worse. It takes 29 calories of feed to produce 1 calorie of beef and 20 times as much water to grow beef as growing cereal grains for human food. This is like saying it costs the US treasury $29 to print one dollar? Does that even make sense?
  • In 1895, it is believed the Atlantic Cod was 1.8 metes or “man-sized. Selective harvesting of these larger fish reduced the size of the cod to 2 feet in 1970s and only 18 inches today or baby sized.
  • A few hundred years ago the jungle fowl used to produce 12 eggs a year. We intervened and today the record production is 364 eggs a day!
  • 7000-10,000 years ago natives in the Andes transformed a poisonous plant into Potato through selective breeding. Potatoes are today the 4th most important staple food in the world. (And of course we know that the other 3, viz. Rice, Wheat and Corn each came from wild inedible grasses through massive human intervention and selective breeding.)

Through these centuries should we as humans have intervened at all? Or will you argue that our species would not have survived had we not? Is tampering with evolution sacrilegious or will you argue that it too is part of human evolution? Does that permit breaking the species barrier through biotechnology and genetic manipulation? Or will you argue that we cannot afford not to?   So who is judging? Monsanto? Pepsi? Stonyfield Farms or Tasty Bite?  Or voters for Prop 37 in California for labeling GMOs in foods or New Yorkers for opining on selling oversized sugary drinks in schools? It is true that sometimes a mind is made up and you cannot confuse it with facts however compelling. Your center is often very different from the center of gravity. For now it does not matter what you believe in for it will change and it will evolve.We live in interesting times. Lets hope we don’t allow decisiveness to trump facts.Lets strive to magically balance public health, planet health and corporate health.

A Pyramid turns into a Plate

/*! elementor - v3.16.0 - 20-09-2023 */ .elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=".svg"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}

Sweden may believe in socialized medicine. The US clearly doesn’t. But despite deep differences in approach, both can agree that it is imperative for good governments to educate their population on health and nutrition. Ideally, this should keep people healthy and drive national healthcare costs down. Socially and economically, these are both good outcomes.

The US has been active in providing nutritional guidelines for Americans for almost 100 years. President Lincoln signed the Agricultural Act that created the USDA in 1862. Almost 50 years later, under President Woodrow Wilson, the USDA launched its first nutritional campaign; fittingly, aimed at children. Even way back then the first food guide (Hunt, 1916) created five categories that included milk & meat; cereals; vegetables & fruits; fats & fat foods; and sugar & sugary foods.

75 years and 4 versions later in 1992 the now famous (and recently retired) Food Pyramid was launched in the US. Ironically, this was inspired by Sweden! It was first conceived there in 1972 as a response to high food prices in Scandinavia, so consumers could strike a balance between nutrition and affordability.

The US Government has just taught us that despite being adopted by more than 25 countries (with minor variations) the Pyramid is not a stable structure anymore (outside Giza!). We have just retired it and replaced it with the Food plate.

“Why”- you may ask if you are a pyramid lover. “Who doesn’t understand it? Why fix it if it ain’t broke?”

But others argue that it was ineffective. Since the pyramid was launched in 1992 Americans have become fatter, unhealthier and poorer, they say. What makes this whole situation doubly ironic is that while the USDA launched the Pyramid, the FDA launched the nutri label. While the Nutrition Labeling and Education Act (NLEA) was passed in 1990, its implementation was almost in tandem with the Pyramid.

But this USDA-FDA double header has not slowed the galloping healthcare costs in the country. According to a 2011 World Health Organization study, the United States spends more of its GDP (18%) on healthcare and more per person ($8600) than any other nation. We spent $2 trillion on healthcare last year!

The unfortunate truth is, much of this can be directly attributed to the food we eat. Equally, it’s because of the food we don’t eat.

Here are some hard hitting facts:

Today more than 2/3rds of adults are overweight! In fact the problem is so severe that epidemiologists studying obesity have now resorted to categorizing folks as “overweight”, “obese” and “extremely obese”!

Emory University’s Rollins School of Public Health found in a recent study that Americans, 50 and older are today twice as likely to be diagnosed with heart disease than Europeans.
The Census Bureau report (Sep 2011) said US Poverty rose to 15%, highest since 1993

Such a dismal report almost begs federal intervention. We probably have the healthiest President and First Lady in the history of the White House today. So it’s no surprise they are deeply concerned by the failing health of Americans. That concern is best symbolized by Michele Obama’s lead in launching the Food Plate replacing the Pyramid.

For a light handed government, it is tempting to tinker with recommendations instead of regulations and hope free markets and responsible corporations will somehow make us all healthy. But noble intentions notwithstanding, this plate is unlikely to point us in the direction of good health and wellness. Let’s take a closer look at the plate.

Vegetables, Fruits, Grains and Dairy in the picture above are all foods. They can and should be eaten daily in some proportion that the plate is trying to convey. But there is a problem. “Protein” in the bottom quadrant of the plate is not a food! Proteins are organic compounds that contain nitrogen. They are molecules made up of amino acids. Meat is not protein. It may be an example of a food that contains protein. Like eggs. Like vegetables. Like amaranth. Like quinoa. Like lentils.

Surely, we quibble. “Protein”, USDA may say, is common parlance for meat. So why not chose to substitute food with amino acid in this quadrant! Maybe we should be grateful that they did not change vegetables to carbohydrates or fruits to sugar and dairy to fat.

But the real BIG problem with The Plate is the hyperproteinization of America. I could not help making some calculations. I measured the area of the “Protein” sector in the diagram and found it was around 23% of the plate. As it turns out the recommended daily value of protein is 10-35% or around 50 grams, give or take a few. You might think these 2 ways of saying it is confusing and not internally consistent. You are right. They are not. Is 50 grams 10% or 35%?

But that is a whole different discussion.

Hyperproteinization will result because Vegetables, Grains, Dairy, all contain protein. Fruits contain less, but they too contribute their share. So the total intake in an already protein rich society as a result of this plate is way beyond what our bodies need. Enough studies have shown the direct linkage of excessive protein to cancer, obesity and heart disease.

I think we need to revisit The Plate. 150 years after Abraham Lincoln, we still haven’t got it right. When the history of nutrition science and public policy is written 150 years from now, we don’t want them to say we told our citizens to eat vegetables, grains, fruits and proteins.
