Chile Peppers Boost Metabolism

Chile peppers add a much-appreciated heat to chilly-weather dishes, and they can also give a boost to your metabolism. Thank to capsaicin, the compound that gives fresh chiles, and spices including cayenne and chipotle, their kick.

Studies show that capsaicin can increase the body's metabolic rate (causing one to burn more calories) and may stimulate brain chemicals that help us feel less hungry. In fact, one study found that people ate 16 percent fewer calories at a meal if they'd sipped a hot-pepper-spiked tomato juice (vs. plain tomato juice) half an hour earlier.

Recent research found that capsinoids, similar but gentler chemicals found in milder chile hybrids, have the same effects-so even tamer sweet paprika packs a healthy punch. Capsaicin may also lower risk of ulcers by boosting the ability of stomach cells to resist infection by ulcer-causing bacteria and help the heart by keeping "bad" LDL cholesterol from turning into a more lethal, artery-clogging form.
