Gut Bacteria Affects Your Brain and Mental Health

Dr. Komaroff, Professor of Medicine at Harvard Medical School, on the importance of keeping a health gut:

"Certain nerves connect the brain and the gut: bacteria in the gut can send signals through those nerves to the brain...Research in the past decade has found that gut bacteria may influence our emotions and cognitive capabilities. For example, some bacteria make oxytocin, a hormone our own bodies produce that encourages increased social behavior. Other bacteria make substances that cause symptoms of depression and anxiety. Still others make substances that help us to be calmer under stress."

"Finally, the gut bacteria also have been shown to influence our vulnerability to certain brain diseases, including Alzheimer’s disease, Parkinson’s disease, and autism."

Myth: Eggs Cause High Cholesterol and Heart Disease

A meta-analysis of studies published in the Journal of the American College of Nutrition discovered that there was no significant link between the consumption of eggs and coronary heart disease.

"Based on the results of this meta-analysis, consumption of up to one egg daily may contribute to a decreased risk of total stroke, and daily egg intake does not appear to be associated with risk of CHD....Overall, summary associations show no clear association between egg intake and increased or decreased risk of CHD. Eggs are a relatively low-cost and nutrient-dense whole food that provides a valuable source of protein, essential fatty acids, antioxidants, choline, vitamins, and minerals."
