Phytochemicals in Vegetables and Health Protective Effects

摘要

Phytochemicals/ phytonutrients/ phytonutriceuticals are organic compounds derived from plants that have health protective effects. Besides the common nutrients such as carbohydrates, amino acids and protein, there are certain non- nutrient phytochemicals in vegetables that have biological activity against chronic diseases. They are low in fat and like all plant products, contain no cholesterol. Most phytochemicals are found in relatively small quantities in vegetable crops. However, when consumed in sufficient quantities, phytochemicals contribute significantly towards protecting living cells against chronic diseases.
