Avocado fruit provides monounsaturated fats, fiber, vitamins, and minerals. People eat the whole fruit or take it as oil, powder, or extract supplements. The oil is also applied to the skin for moisture.
Healthy cholesterol levels already in the normal range and normal cardiovascular function are two reasons people use avocado. Whole fruit is eaten with meals. Oils and powders are also taken with food, though the right amount depends on the form you choose.
Regular avocado eating can raise serum potassium. Anyone managing chronic kidney disease, high potassium, or taking potassium-sparing diuretics should keep that in mind. Standard amounts of the fruit flesh and oil are generally safe for most people. Extracts made from the leaves or seeds are not well studied for safety.
