Great research and article. I saw it.
The implications are that if we change our gut flora with macrobiotics we can better control obesity.
There are contributing factors to obesity such as lack of exercise and over eating but they are finding more and more that some people can gain weight eating half the calories of other people irrespective of activity.
If the gut flora (thousands of living bacteria) can change our metabolism than they likely can directly cause and effect with heart disease, diabetes, cancer, MS, MD and other chronic illnesses.
Another article talks about tooth decay stopping when you stop eating refined grains, such as breads and other white starchy carbohydrates like potatoes or popcorn (sugar and near sugars). We have known for some years that cancer is promoted with high sugar diets.
Other research indicates flora changes due to over use of antibiotics and eating foods high in sugars as well as low consumption of fermentation foods like olives, pickles, yogurt......
This whole line of research supports old world medical treatments of holistic treatments rather than chemicals and modern drugs.
The body heals itself if it is properly fueled with nutritious produce without chemical pollution.
