What makes a chilli sauce different from any other sauces is the presence of capsaicin. It is the compound that gives chillies their heat. Studies show that capsaicin is an amazing antioxidant. It also has anti-inflammatory and can prevent the effect that carcinogenic substances have on the body. But most chilli sauces also contain other ingredients as well, including sugar and salt. So even though capsaicin might be good for the body, you should still not consume too much chilli sauce as it can increase the blood sugar and sodium levels.
