Luckily, diet can correct this delicate balance in the system. Low-grade chronic inflammation, thought to be the result of an overstimulated immune system, increases the risk of metabolic disorders such as heart disease and obesity. Complex interactions between the intestinal lining, short-chain fatty acids produced by fermentation of dietary fiber by gut microbes, and pro-inflammatory chemicals called cytokines are all…
