Modern Life Gives a Blow to the Gut
Evidence has been mounting for some time indicating that modern dietary and health practices are having a harmful effect on some aspects of health. Now, researchers can begin to quantify that effect on one system, the microbiome of the human gut. It seems that those living in modern society host 40% fewer beneficial microbes on their skin and in their guts than those untouched by modernity. This finding came from a study of an isolated tribe in South America. The BBC reports: http://www.bbc.com/news/health-32543176

A Junk Food Diet Adds to the Gastric Distress
A novel experiment in the U.S. and Africa has demonstrated the harm done to the alimentary system by a diet high in junk food. Switching the Americans to a low-fat, high-fibre diet showed immediate benefits, while changing the Africans over to a junk food diet led to an immediate decline in their health. The study was small, so conclusions must be reserved, but the dietary changes only took two weeks to result in these measurable health changes.
