Many studies show that exercise helps to prevent heart attacks, and it may do so by changing the bacteria in your colon. A recent study from Finland shows that exercising for just six weeks, without any additional change in diet or lifestyle, can increase healthful anti-inflammatory bacteria (Akkermansia) and reduce harmful inflammation-promoting Proteobacteria in your colon (Front Microbiol, October 3, 2018).
In this study, 17 sedentary and overweight women started a heart-rate-regulated exercise program on stationary bicycles for three training sessions per week. After six weeks, stool cultures showed healthful colon bacteria changes, even though the subjects did not lose any weight. There was also a significant reduction in phospholipids and cholesterol in VLDL cholesterol, which is believed to help prevent heart attacks because VLDL cholesterol is converted into the harmful LDL cholesterol that helps to form plaques in your arteries. Exercise also decreased Vascular Adhesion Protein-1, a measure of inflammation that causes plaques to form in arteries and break off to cause heart attacks.
