The heat in peppers is produced by capsaicin, which generates chemical processes within cell structures that have an affect on adenosine triphosphate (ATP) reactions involved in a process known as thermogenesis, by which the body generates heat or energy, which in turn increases not only body temperature, but also metabolism. Wow! that was a heavy paragraph!
Okay bottom line it's all about Capsaicin: considered to be a negative calorie food, or one that helps burn fat through metabolism. They increase the heart rate, so that more energy is utilized by the body, therefore burning more fat and increasing metabolic rate. Nearly all chili peppers are considered negative-calorie spices and can be sprinkled on foods to keep metabolism running at higher speeds up to several hours after ingestion.
Another benefit I stumpled upon is cayenne peppers can actually ease your stomachaches and digestive disorders. These hot peppers prevent stomach ulcers with a one-two punch: first they kill harmful ulcer-causing bacteria; two, they stimulate the cells lining the stomach to secrete protective buffering juices that prevent ulcer formation.
Oh yes there is more benefits, In fact, cayenne pepper will help clear up hemorrhoids if taken regularly -- especially if the hemorrhoid sufferer changes their diet to one very rich in fiber.
Rule of thumb, the smaller the pepper, the better. The seeds and ribbing on the inside are what contains the metabolic boosting agent, capsaicin. So there are health benefits to Peppers....SPICE IT UP!
