Significance of vegetable and fruits in our diet
Vegetables a rich source of micronutrients and macronutrients

They contain abundant amounts of iron, calcium, vitamin C, folic acid, carotenoids (precursors of vitamin A) and phytochemicals.
Vegetables – A Source of Phytonutrients
Beyond simply being a mechanism for conveying calories, food from vegetables is a source of special ingredients than can prevent and treat disease and transform your health. These are called phytonutrients — special plant chemicals that are not calories, protein, fat, carbohydrates, vitamins and minerals, but special molecules that interact with your biology, special molecules that act like switches on your DNA to heal your body. Plants use colors as their protective mechanisms. Those colors are the sources of the phytonutrient that act like medicine in our bodies. We use their defense mechanisms to help our bodies function better — these are the anti-inflammatory, detoxifying, antioxidant and hormone-balancing compounds that we should eat every day to prevent disease.
