5. Grapefruit
This tangy, sour fruits are often a popular choice for people who are trying to lose weight, and for good reason; grapefruit is low in calories and contains properties that can boost your metabolism.
Grapefruit is also a valuable source of several important vitamins and nutrients, including vitamin A, vitamin C, vitamin B1, biotin, copper, fiber and pantothenic acid, so they’re great for your health in so many ways.
Another reason why grapefruit is good for you is because it is low in potassium. One half of a medium grapefruit only contains about 180 mg of this nutrient.
