I already posted a thread on this earlier last week. They are not only good for your immune system, but are also good for diabetics, your heart, and really do a wonder on preventing prostate cancer. I honestly think chili's are one of those superfoods. Heck, I think my wife and I ate some bad food camping resulting in some type of food poisoning. I got sick once, and am already feeling better. I think most people would be sick for a few days over that. Besides that I VERY, VERY rarely even get the slightest bit sick. I also do everything wrong. Eat with dirty hands at times, eat rare red meat, ect. (I think that'll oddly boost your immunes system too. I think you can overclean your body. You can't have a good immune system without exposing it to germs.) Anyways, here's that article.http://www.whfoods.com/genpage.php?tname=foodspice&dbid=29 Also, on a sidenote I also agree that Western medicine focuses far to much on prescription meds. IMO for the most part it's really about big corporations making more money not your health.
