This post is going to be a little different from what I typically share with you, but lets just go with it. Generally speaking, I try to stay up-to-date with the latest health and wellness news and usually when I come across something interesting, I mention it on Facebook and Twitter. But lucky you, now you can also read about it right here. So to kick it off, I first need to thank my dad.
My dad is a physician (OB/GYN), and like most physicians, he did not receive a whole lot of education in the nutrition department when he was in medical school or during residency. However, over the years, especially since my diagnosis in 2006, he has taken his own initiative to learn more about the relationship between diet and health. After making significant changes to his own diet, many of his chronic health issues are gone (imagine that!) and for an added perk – he lost about 30 pounds and looks fantastic. How’s that for a medical doctor nowadays? He’s always made me proud, but changing how he eats in his late 50’s (and maintaining it) is definitely at the top of my list of reasons. Way to go, dad.
I shouldn’t have been surprised when he handed me an article from the April 6, 2011, issue of JAMA (The Journal of the American Medical Association). In case you are not familiar with this publication, JAMA is a peer-reviewed medical journal. JAMA only accepts about 9 percent of the manuscripts it receives annually, so you can forget about reading anything light and fluffy in this publication. This is serious stuff, people! I was thrilled to see that this article made the cut in the oh-so-prestigious JAMA, and even better, that it was my dad who tore it out of his issue and saved it for me until I was back in town for a visit.
So now that you’ve gotten enough background information, I think it’s time for me to get to the point.
The article argues that there have been three major revolutions in food technology as humans have strived to improve food availability, digestibility, safety, transportability and storage life.
The first notable technology was the development of stone tools for hunting and food preparation in the Paleolithic era. The combination of stone tools and fire for cooking greatly improved diet quality and diversity, contributed to the development of a larger brain and assisted in the evolution of modern day Homo sapiens (aka human beings as they exist today).
The second huge development occurred as a result of the domestication of staple grains, also known as the Agricultural Revolution. This lead to a few monumental changes in society: (1) a huge increase in the availability of calories (2) an explosion in the human population (3) the creation of civilization. Of course, there were some unpleasant “side effects” to deal with such as rampant protein and micronutrient deficiency diseases. This occurred because grains have a lower ratio of nutrients to calories than animal or plant foods.
Next up – the Industrial Revolution of the 19th century. This technological advance permitted mass production of refined flour and concentrated sugar. The Industrial Revolution established the backbone for a commodity-based diet, characterized by food extrusion technology and biotechnology. As a result, fast food and ultraprocessed products are widespread today.
So what are ultraprocessed products? Well, they look like natural foods, but only on the outside. Lets take strawberry-splash fruit gushers as an example. This ultraprocessed product only contains a teeny tiny bit of strawberries; the rest comes from highly processed ingredients that never existed in the food supply and comes from extreme chemical and mechanical manipulation of three species – corn, wheat and soy.
From JAMA’s page to your eyes: “A diet based on ultraprocessed products may promote obesity and chronic disease through a variety of mechanisms, including high energy density; large portion size; low content of fiber, micronutrients, and phytochemicals; poor quality of dietary fat; high glycemic load; and high-intensity flavoring.” What this means is that foods that are heavily processed (do not exist naturally in nature) make us sick and fat because they are high in fat and sugar and low in nutrients, fiber and phytochemicals. Side note: phytochemicals come from plants and help protect our bodies against diabetes, heart disease and cancer.
Also important to note is that during the process of creating these food-like-substances, water is extracted to increase shelf life and decrease transportation costs. However, this actually increases the number of calories in each bite of food. So a big “thank you” to the food companies for having their consumers’ best interests in mind when creating these products and for not focusing on their own bottom line. Not!
Humans regulate solid food intake by volume, not calories, so when we eat tiny bits of food crammed with calories, it’s not surprising that we are still hungry when the package is empty!
Ultraprocessed food has poor dietary fat and typically emphasizes trans fat and saturated fat, which increase our risk for heart disease. We need fat. That’s a fact. But not if it comes from these artificial food-like products. The fat that is good for us, polyunsaturated fat, is often removed or destroyed in the manufacturing process.
Generally speaking, the more we process our food, the greater the glycemic index. The glycemic index of a food measures how fast the food increases our blood glucose. So here’s another reason why so many of us are overweight, suffering from diabetes and our energy levels are all out of whack.
Don’t forget that ultraprocessed products typically emphasize sugar, salt and fat. This intense flavoring not only messes with our weight and health, but also overrides our endogenous satiety mechanisms, so our body doesn’t know when we should be hungry or feel full. So we eat more. And more. And more.
JAMA argues (and I have to agree) that ultraprocessed products cause excessive weight gain and chronic disease. A diet that focuses on minimally processed foods prevents heart disease and other chronic diseases.
So what do we do now? We have all this great technology at our fingertips, but it’s also making us fat and sick. JAMA argues that we need to become more responsible with this technology that should be guided by public health instead of short-term economic considerations.
Here are some suggestions to promote a more appropriate use of food technology.
Government
* Restructure agricultural subsidies to promote high-quality foods (vegetables, fruits, legumes)
* Regulate food advertising / marketing
* Adequately fund school lunch and related nutrition programs
Public
* Buy fewer ultraprocessed products
* Prepare meals from basic ingredients in the home
* Give preference to restaurants that prepare meals from scratch
Schools
* Prepare lunch and snack foods from whole ingredients
* Institute a new “home economics” curriculum to promote cooking
Restaurants
* Provide intermediate options between gourmet food and fast food – convenient, inexpensive meals prepared from whole foods
Industry
* Use higher nutritional value ingredients versus commodities
* Market minimally processed / traditionally processed products
* Use preservation methods that protect polyunsaturated fats
We can’t go back in time and change history. Our society has become extremely dependent on technology in every aspect of our lives. I was raised with the belief that just because you can do something doesn’t necessarily mean you should. I agree with JAMA; it’s time to move toward a more appropriate use of technology. We are all responsible for our own actions; no one party is responsible for the current state of our health, or lack there of.
If my dad can take control of his health in his late 50’s and JAMA can make claims against ultraprocessed products then I think we are slowly starting to head in the right direction.
