These bioactive medicinally important natural compounds present in vegetables offers various health benefits like prevention of cardiovascular disease, cancer and other diseases. Chlorogenic acid and nasunin present in brinjal have anti carcinogenic, anti-obesity, and anti-diabetic properties. Lycopene present in tomato, watermelon and carrot helps to protect against cancer and fight against infection. Allicin, allyl propyl disulfide and di-ally disulfide present in onion and garlic etc., help to protect against certain cancers and heart disease; and also acts as immune-booster. Crucifers are the important source of sulforaphane which have anti-cancer property. Flavonoids (isoflavones) rich in beans lower the cholesterol and protect against cancer.
