Chili pepper contains an impressive list of plant derived chemical compounds that are known to have disease preventing and health promoting properties.
Chilies contain health benefiting an alkaloid compound in them, capsaicin, which gives strong spicy pungent character. Early laboratory studies on experimental mammals suggest that capsaicin has anti-bacterial, anti-carcinogenic, analgesic and anti-diabetic properties. It also found to reduce LDL cholesterol levels in obese individuals.
Fresh chili peppers, red and green, are rich source of vitamin-C. 100 g fresh chilies provide about 143.7 µg or about 240% of RDA. Vitamin C is a potent water-soluble antioxidant. It is required for the collagen synthesis in the body. Collagen is the main structural protein in the body required for maintaining the integrity of blood vessels, skin, organs, and bones. Regular consumption of foods rich in vitamin C helps the body protect from scurvy; develop resistance against infectious agents (boosts immunity) and scavenge harmful, pro-inflammatory free radicals from the body.
They are also good in other antioxidants like vitamin A, and flavonoids like ß-carotene, α-carotene, lutein, zea-xanthin, and cryptoxanthin. These antioxidant substances in capsicum help to protect the body from injurious effects of free radicals generated during stress, diseases conditions.
Chilies contain a good amount of minerals like potassium, manganese, iron, and magnesium. Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase.
Chilies are also good in B-complex group of vitamins such as niacin, pyridoxine (vitamin B-6), riboflavin and thiamin (vitamin B-1). These vitamins are essential in the sense that body requires them from external sources to replenish.
