Is Grapefruit a Good Source of Vitamin C ?
Grapefruit is a good source of vitamin C, contains the fiber pectin and the pink and red hues contain the beneficial antioxidant lycopene
Your body uses vitamin C for tissue growth and repair, immune function, making collagen, keeping your teeth and bones healthy and healing wounds. Since vitamin C is a water-soluble vitamin, you need to consume foods that contain this vitamin every day because your body does not store it. Grapefruit is one source for vitamin C.
Vitamin C Content
Half of a medium grapefruit provides you with 38 mg of vitamin C to go toward the recommended daily allowance of 75 mg per day for women and 90 mg per day for men. It is a good source of vitamin C, although a medium orange, a cup of strawberries, a 1/2 cup of cooked broccoli or a 1/2 cup of raw chopped red bell pepper all contain more vitamin C.
Possible Health Benefits
Components in grapefruit, including flavonoids, d-limonene, lycopene, naringenin glycoside, pectin and vitamin C may help to lower your risk for gum disease, heart disease, high blood pressure, cancer, infections, gout and arthritis. Although some people take vitamin C to fight colds, the evidence is conflicting as to whether this is beneficial, according to the Linus Pauling Institute.
Besides containing vitamin C, grapefruit has a lot of other beneficial nutrients. Half of a medium grapefruit only has 40 calories, and provides 1 g of fiber and 1 g of protein without any fat. It contains 4 percent of your vitamin A, vitamin B-6, magnesium, thiamine and folate and 2 percent of the daily requirements for calcium, riboflavin and niacin.
Grapefruit can interact with certain medications, so you should speak with your doctor before consuming large amounts of grapefruit or grapefruit juice to make sure it is safe for you. This is particularly important for elderly individuals and those with liver disease, according to Drugs.com.
