Vegetables and fruits should be every foodie’s best friend. Due to their low caloric content, you can eat and eat without having to worry about your weight. They are very rich in vitamins and minerals and the high amount of fiber ensures that you not only get full for less, but your digestive track thanks you for taking them. The U.S. dietary guidance recommends at least one serving of dark green and an orange vegetable daily. Your goal, however, should be to eat a rainbow. Play around with the colors to get the most out of them. This is because each color represents a different nutrient and phytochemicals as we shall see below.
White Fruits and Vegetables
White vegetables are rich in potassium which provides relief from blood pressure, heart and kidney disorders, stress and anxiety while enhancing metabolism, the nervous system and muscle strength; magnesium which is an essential component in many metabolic reactions; vitamin C which is an antioxidant that prevents cellular damage, maintains healthy gums and aids healing of wounds; and fiber which increases satiety, regulates blood glucose and improves digestion.
