Nutritional Properties Of Grapefruit
Grapefruit is an excellent source of many nutrients and phytochemicals that contribute to a healthy diet. Grapefruit is a good source of vitamin C, pectin fiber, and the pink and red hues contain the beneficial antioxidant lycopene. Studies have shown grapefruit helps lower cholesterol and there is evidence that the seeds have high levels of antioxidant properties. Grapefruit forms a core part of the “grapefruit diet”, the theory being that the fruit’s low glycemic index is able to help the body’s metabolism burn fat.
