GMO's and Obesity

It’s no secret that Americans are getting fatter. And sure, the usual suspects—more processed food being packed into our diets and too-frequent fast food fixes—clearly play a part, but now there’s another theory: genetically modified (GM) crops, according to new research.

As part of a long-term project studying the health effects of GM foods—crops that have had their DNA modified to resist pesticides and drought—researchers from Norway fed food containing GM corn to one group of rats and food containing non-GM corn to another group. Over the course of 90 days, the rats on the GM-corn diet grew fatter and ate more food than the rats on the non-GM diet. The researchers also noticed that rats got fatter when they ate fish that had been raised on GM corn.

"If the same effect applies to humans, how would it impact people eating this type of corn over a number of years, or even eating meat from animals feeding on this corn?" lead researcher, Ã…shild Krogdahl, PhD, a professor at the Norwegian School of Veterinary Science, told the Norwegian news site ScienceNordic.

Then there’s the nutrient issue. Research from the nonprofit Organic Center has found that nutrient levels in modern crops are anywhere from 10 to 25% lower than they were 50 years ago, likely because the crops are bred for higher yields, as many GM crops are. As nutrient levels go down, we have to eat more to get the recommended levels of nutrients we need, which may explain why GM crops led to overeating rodents in the Norwegian study.

Bitter Foods

Bitterness in some foods and herbs is very important to our health. The bitterness sends a chemical reaction throughout our bodies and has numerous health benefits.

Many nutritionists, herbalists, and other health experts believe that far too many modern industrialized humans are deficient in bitter substances, which in part contributes to our epic rise in digestive related illnesses, inflammatory conditions, immune challenges, diabetes, and more. (1) Here are a few of the health benefits of bitter foods.

1. Helps to absorb nutrients

While bitterness is often perceived as unpleasant, the interaction between bitter constituents in foods and our bitter taste receptors stimulate the production of gastric acid in the stomach. This helps prime the stomach for the food it is about to encounter. “Bitter foods and herbs help to stimulate digestive juices and support food digestion,” says professional dietitian Nicole Dube of Halifax, N.S. “Bitter foods help stimulate our taste receptors on the tongue, which subsequently stimulates enzyme production and bile flow. The better your food is digested, the more nutrients you will absorb from your food. It doesn't matter what you eat, if you can't absorb it, it won't be of much benefit to you.” Dube often recommends eating a dandelion salad for people with digestive problems.

2. Balances taste buds and controls that sweet tooth

The more bitter greens we eat, the more bitter greens we want. “We all have different sensory levels. It depends on genetics, what you’ve trained your body to like, what your mother ate when you were in utero or what your heritage is,” says Theresa Albert, a Toronto-based registered nutritionist and founder of the website, My Friend in Food. In Ayurvedic tradition, bitter foods are thought to reduce food cravings and aid in weight loss. In TCM, bitter foods are prized for ‘removing heat’ in the body – could that speak to their very modern ‘anti-inflammatory’ benefits? (2)

3. Cleanses the body

Bitter roots and veggies contain fiber to help sweep wastes through the digestive tract. Bitter foods also contain sulfur-based compounds which support the natural detoxification pathways in the liver; helping it to do what it is meant to do – keep your body clean and clear. “We’re just starting to discover the benefits of greens,” says Albert, who explains that centuries ago, in ancient Chinese and Hindu diets, culinary traditions regularly included bitter foods.

4. Stimulates metabolism

Bitter foods and herbs like green tea have been shown to boost metabolism. Drinking green tea is one of the easiest ways to rev up your metabolism. A study reported in the American Journal of Clinical Nutrition found that green tea-extract increases the metabolism by 4% over a 24-hour period. Green tea has also been shown to inhibit fat absorption—the movement of glucose into fat cells, [support healthy] glucose levels after eating a meal, prevent insulin spikes which prevents fat storage, and reduce appetite. People that choose sweet foods over bitter foods are also at risk for metabolic syndrome. (3)

5. Fights free radicals and stimulates immune function

Recent studies have shown that bitter foods, including dark chocolate, can help fight free radicals in the body. Of course, Bitter foods are usually nutrient dense Bitter foods pack plenty of nutrition into each bite. For instance, beta-carotene for healthy skin; folate for a healthy nervous system; vitamin K for healthy blood clotting and phytochemicals for healthy inflammation response, managing cholesterol, balance hormones, detoxify the blood and metabolizes fats. Many greens are also mineral rich; gentle cooking will help make those minerals more bioavailable to the human body.
