Grapefruit makes a healthy addition to any meal. This softball size fruit is known for having nutrients beneficial to your health. Three types of grapefruit can be found in most supermarkets: white (blond), red and pink. For an extra boost choose the pink or red varieties, which contain higher concentrations of some nutrients.
Cancer-Fighting Nutrients
Grapefruit contain two main phytonutrients found to help fight cancer. Limonoids, in the flesh of the fruit, are known to stimulate the production of enzymes that help the liver rid the body of toxic substances more easily. Research also has shown limonoids have the potential to fight breast and colon cancer, as well as cancers of the mouth, skin and stomach. Lycopene is a phytonutrient found in the pink and red varieties of the fruit. The antioxidant capabilities of lycopene have been shown to have anti-tumor properties that reduce the risk of some cancers, such as prostate cancer.
Vitamin C and Vitamin A
The grapefruit is an excellent source of Vitamin C, with half a grapefruit providing about 47 mg. Similar to lycopene, Vitamin C is also an antioxidant. It is associated with a reduced risk of inflammation, which is beneficial for people suffering from asthma and rheumatoid arthritis. Vitamin C also is associated with a reduced risk of heart disease, stroke and some cancers. Research has also found adequate intake of Vitamin C may play a role in reducing cold symptoms. Grapefruit is a good source of Vitamin A, which plays a role in cell growth and development, reproductive and bone health and eyesight.
Fiber
Grapefruit provides soluble fiber in the form of pectin. Pectin has been linked to slowing the rate of hardening of the arteries (atherosclerosis), a condition that increases the risk of heart attack and stroke. Pectin also is associated with a reduction in LDL ("bad") cholesterol levels.
Drug Dangers
Grapefruit juice has been found to interfere with effectiveness of some common medications. If you currently take prescription drugs, talk with your doctor before eating grapefruit. Eating grapefruit can negatively affect the performance of immunosuppressant drugs, calcium channel blockers, antihistamines, hormones, antiviral agents and statins.
