Hot chili peppers can be extremely beneficial for keeping blood pressure in check. People who crave very spicy food usually do not have a desire for salty food. A large study done in China reported that capsaicin, the spicy component of chili peppers, stimulated the same area of the brain as did salt. In so doing, it made the brain more sensitive to salt which potentially made a person consume less salty foods. Results of the study were published in “Hypertension”. The test had 606 participants. All were given water with different amounts of capsacin. The more of the hot spice that was present the less of a desire for salt was recorded. Another benefit of red and green peppers is that they are the highest source of Vitamin C.
