Does Cayenne Increase Metabolism?

Originally from Central America, cayenne peppers are now widely cultivated around the globe for culinary and medicinal purposes. Its long red fruit contains capsaicin, the part of the chili that makes it hot and constitutes the plant's medicinal source. Although the need for further scientific evidence exists, cayenne has a reputation as a treatment for a wide range of complaints and appears to boost metabolism. As with all herbs, however, check with your doctor before use.

About Metabolism

Metabolism is a general term for the physical and chemical processes by which your body converts air and food into substances it needs to function. Boost your metabolism by exercise, hormonal activity, elevating your body temperature and through the natural body action that occurs after consuming a meal.

Cayenne ID

Cayenne, a shrubby perennial plant, grows to heights of 3 feet and features oval leaves and yellowish flowers. According to Andrew Chevallier, naturopath and author of the book "DK Natural Health Encyclopedia of Herbal Medicine," cayenne earned such popularity in Mexico that it is even used as an ice cream flavor. The plant's elongated, bright red fruit has white seeds inside, a leathery exterior and contains its key constituent capsaicin. Phyllis A. Balch, certified nutritional consultant and author of the book "Prescription for Herbal Healing," says that cayenne is just one of 130 species of pepper that provides the therapeutic compound capsaicin.

Cayenne Benefits

Capsaicin appears to accelerate your metabolism by stimulating a stress hormone release in your body. According to PubMed, a 1999 study conducted by Laval University in Canada indicated that consuming cayenne at breakfast reduced appetite, leading to lower fat, protein and caloric intake for the remainder of the day. Phyllis A. Balch adds that cayenne boosts your metabolism and helps your body burn fat instead of storing it.

Cautions and Considerations

Generally considered safe, consuming high levels of hot peppers can lead to stomach irritation and liver and kidney damage. High levels also can inhibit the liver enzyme CYP1A2 from helping the liver eliminate certain medications from your body including aspirin, clozapine, warfarin and theophylline. The University of Maryland Medical Center cautions that pregnant and nursing women, children and people with ulcers should avoid eating cayenne peppers.
