Phytonutrients are also referred to as phytochemicals. Phytonutrients are natural, bioactive compounds derived from plant sources. They are neither vitamins nor minerals. Phytonutrients are compounds concentrated in the skins of many vegetables and fruits along with accountable colour, hue, scent and flavour.
They are non-nutritive plant chemicals that have a valuable effect on disease prevention. Their role in plants is to protect the plants from diseases, insects, excessive heat, and UV rays in addition to pollutants in the air and soil. In other words, phytonutrients are part of the plants’ immune system.
Phytonutrients have been identified as containing properties that have beneficial effects on health. One of the most important roles of phytonutrients is functioning as antioxidants which are able to neutralise free radicals. Phytonutrients also help in strengthening our body’s immune response.
Phytonutrients such as carotenoids and flavonoids act like a protective armour to keep invading pollutants and germs from entering cells. In addition, phytonutrients protect body cells from cellular damage. They help cells repair themselves by stimulating the release of protective enzymes or enzymes that rebuild damaged cells.
