Disregard the mention of obesity. I think that this study applies to anybody! The important aspect is that hot chili peppers reduce inflammation.
For the past year I rarely ate chili peppers but for the previous seven years of living in a spicy part of China I ate chili peppers practically every morning for breakfast by either cooking or having a bowl of 热干面
on the way to work (I ate and walked at the same time.) I felt better when I ate a lot of chili peppers however it may have been a cause of chronic loose and mucousy stools for two years. The 热干面 has lots of noodles in it but they are pre-cooked on the previous evening, cooled and then warmed in hot water for a few seconds in the morning before serving them. So they may have been partially resistant starch. Still, I think I could feel the noodles causing some inflammation and hyper-activity in me but the inflammation was not bad as it was after quitting eating hot chili peppers. 热干面 was the only large source of starch I was have each day, otherwise I was just consuming meats and vegetables, with little fruit.
The article talks about the effects of hot chili peppers on the population of the microbiota and the subsequent effect on inflammation. The capsaicin in the hot peppers induced increased levels of butyrate-producing bacteria, while it caused lower levels of members of a specific lipopolysaccharide (LPS)-producing family. LPS is a surface antigen of gram-negative bacteria like Klebsillia and it triggers inflammation.
I'm going out right now to stock up on peppers. Wish me luck
