Vegetables play vital roles in our diets. They aid and support normal functions of different body systems. Vegetables provide our cells with vitamins, minerals, fiber, essential oils and phytonutrients. You can eat them cooked or raw. But in certain instances, it is better to eat them raw. If you hated them raw, cooked vegetables are still a healthy choice. However, cooking destroys essential nutrients such as vitamin C and also kills vital enzymes that help your body to digest such foods.
