Cayenne pepper, a popular spice known for its heat, offers significant health benefits for the eyes and heart. According to registered dietitian Alexis Supan, a single teaspoon provides 15 percent of the daily recommended intake of vitamin A, which is essential for eye, organ, reproductive, and immune system health.
The spice also contains vitamins B6, K, and C. Vitamin K helps stop bleeding and strengthens bones, while vitamin C supports the immune system. Supan notes that one fresh pepper contains 72 percent of the recommended daily amount of vitamin C and 50 percent of vitamin A.
Cayenne peppers are rich in antioxidants, which protect cells and may help prevent cancer and heart disease. The compound capsaicin, responsible for the heat, has been shown to reduce inflammation, a key factor in cancer development. Supan adds that capsaicin may improve blood flow and lower blood pressure, reducing the risk of heart disease.
The spice also aids digestion by increasing gastric juices and enzyme production, and may help with calorie burning and satiety. Cayenne pepper has been used for over 7,000 years, originating in Central and South America. With a heat rating of 30,000 to 50,000 Scoville units, it is hotter than jalapeño but milder than Carolina reaper peppers, making it a potent addition to a healthy diet.
