Chili Peppers
Chili peppers are available throughout the year to add zest to flavorful dishes around the world and health to those brave enough to risk their fiery heat.
This is the plant that puts fire on your tongue and maybe even a tear in your eye when you eat spicy Mexican, simmering Szechuan, smoldering Indian, or torrid Thai food. Chili peppers belong to the family of foods bearing the Latin name Capsicum.
Chili peppers contain a substance called capsaicin, which gives peppers their characteristic pungency, producing mild to intense spice when eaten. Capsaicin is a potent inhibitor of substance P, a neuropeptide associated with inflammatory processes. The hotter the chili pepper, the more capsaicin it contains. The hottest varieties include habanero and Scotch bonnet peppers. Jalapenos are next in their heat and capsaicin content, followed by the milder varieties, including Spanish pimentos, and Anaheim and Hungarian cherry peppers.
Capsaicin is being studied as an effective treatment for sensory nerve fiber disorders, including pain associated with arthritis, psoriasis, and diabetic neuropathy. When animals injected with a substance that causes inflammatory arthritis were fed a diet that contained capsaicin, they had delayed onset of arthritis, and also significantly reduced paw inflammation. Topical capsaicin is now a recognized treatment option for osteoarthritis pain. Several review studies of pain management for diabetic neuropathy have listed the benefits of topical capsaicin to alleviate disabling pain associated with this condition. In a double-blind placebo controlled trial, nearly 200 patients with psoriasis were given topical preparations containing either capsaicin or placebo. Patients who were given capsaicin reported significant improvement based on a severity score which traced symptoms associated with psoriasis. The side effect reported with topical capsaicin cream is a burning sensation at the area of application.
Red chili peppers, such as cayenne, have been shown to reduce blood cholesterol, triglyceride levels, and platelet aggregation, while increasing the body's ability to dissolve fibrin, a substance integral to the formation of blood clots. Cultures where hot pepper is used liberally have a much lower rate of heart attack, stroke and pulmonary embolism. Spicing your meals with chili peppers may also protect the fats in your blood from damage by free radicals a first step in the development of atherosclerosis. In a randomized, crossover study involving 27 healthy subjects (14 women, 13 men), eating freshly chopped chili was found to increase the resistance of blood fats, such as cholesterol and triglycerides, to oxidation (free radical injury).
Subjects were randomly divided into 2 groups. For 4 weeks, half the subjects ate a freshly chopped chili blend (30 grams/day, about 1 ounce), consisting of 55% cayenne, while the other half consumed a bland diet (no chili). After 4 weeks, the groups were crossed over for another 4 weeks. During the intervention periods, consumption of other spices such as cinnamon, ginger, garlic, and mustard was restricted. Blood samples were obtained at the beginning of the study and after each dietary period.
After eating the chili containing diet, the rate of oxidation (free radical damage to cholesterol and triglycerides) was significantly lower in both men and women than that seen after eating the bland diet. In addition, after eating the chili spiced diet, women had a longer lag time before any damage to cholesterol was seen compared to the lag time seen after eating the bland diet. In men, the chili diet also lowered resting heart rate and increased the amount of blood reaching the heart.
