It may surprise many people, but grapefruit really can help with weight loss! In a small test involving 100 obese people, those who ate half a fresh grapefruit each day lost more weight than the control group that did not. It appears that the effect is partly due to grapefruitís ability to lower glucose levels. Eating grapefruit also appeared to help patients with metabolic syndrome, reducing their insulin resistance.
Although these studies were small and more research needs to be done to determine why and how grapefruit works, the results could be significant for the treatment and prevention of type 2 diabetes.
Grapefruit is rich in flavonoids that are helpful in lowering the risk of cancer and cardiovascular disease. It is a good source of pectin (a soluble fiber that helps lower cholesterol) and vitamin C. Because it is not very sweet, it is a good fruit for those who wish to limit carbohydrate. Grapefruit seeds have also been shown to have an antibacterial effect.
As is often the case, the more brightly colored fruit tends to have more antioxidants and other life-saving compounds. That means that pink- and red-fleshed varieties of grapefruit pack more nutrient punch than white grapefruit, including the antioxidant lycopene, which may help prevent age-related blindness.Nutritional Facts
