Grapefruit Health Benefits

Grapefruit belongs to the citrus family, so it's rich in vitamin C. It is a result of the natural combination between orange and pomelo. Grapefruit is huge in size like pomelo, but looks like an orange from outside. This fruit gets its name from grapes, because like grapes, it grows in clumps and can be found in white, pinkish or reddish pulps having varying degrees of sweetness. The grapefruit tree is cultivated all over the world for its bitter-sour tasting fruits that are loaded with essential nutrients and minerals which help in preventing as well as curing a host of diseases. Let's take a look at the nutritional value of grapefruits that make them such a wonderful fruit for health conscious people.


According to food experts, grapefruit is a rich source of vitamin C, vitamin A, vitamin B5, folate, calcium and dietary fiber (about 12 gram per fruit). The calories in grapefruit are relatively low, approximately 36 in a medium-sized fruit. Also, grapefruits contain high amounts of antioxidants and phytochemicals. The pink or red-colored pulp is due to the presence of a carotenoid phytonutrient, called lycopene (found in tomatoes) that has a strong antioxidant activity. The antioxidant content is claimed to be much higher in grapefruit seed extract (GSE).


Speaking about grapefruit benefits, including grapefruits in the diet is an easy way to ensure good health. They contain negligible amounts of fat, cholesterol and sodium. As per American Heart Association (AHA), grapefruit and grapefruit juice are recommended as healthy food items for the heart. Discussed below are some of the notable benefits of grapefruits:

✔ Promotes a Healthy Skin: The antioxidant content in grapefruit aids in promoting a smooth and healthy skin. Grapefruit and GSE are also used for treating skin allergies, infections and other medical symptoms. It also helps in the treatment of acne and pimple, which are caused due to bacterial infections. When applied topically, GSE promotes quick healing of the skin and also helps to reduce fine lines and wrinkles.

✔ Fights Signs of Premature Aging: Grapefruits contain a high percentage of polyamine. In animal studies, this compound plays a crucial role in reducing the aging process. In short, consuming grapefruits helps in slowing down the aging process. However, more clinical trials are yet to be done to check for the same effectiveness in humans.

✔ Aids in Weight Loss: The benefits of grapefruit in terms of losing weight has been a widely studied topic. The well-known 'grapefruit diet' is based on the fat burning enzyme present in this bitter fruit. Drinking grapefruit juice reduces fat and starch accumulation in the body.

As per the proponents of grapefruit-based food products, there are specific enzymes in grapefruits that minimize the levels of insulin in the blood. Hence, consuming grapefruits and grapefruit-based food products help control diabetes. Another benefit of grapefruit for diabetic patients is the presence of dietary fiber and low carbohydrate content, which are useful for controlling blood sugar levels. If you have a family history of diabetes, consuming grapefruit regularly is a good way of preventing the disease.

Moreover, consumption of grapefruit juice is a good way of curing fever. It is also a great remedy for sore throat and cough.

The fiber present in the fruit, especially in its rind prevents constipation and helps in smooth and regular bowel movements. Grapefruit is also one of the best treatment measures for acidity. The juice of this fruit creates an alkaline reaction in the body, subsequently relieving the discomfort caused due to acidity.

✔ Treats Other Ailments: Being an excellent source of vitamin C, grapefruit is used in combating cold symptoms and inflammatory problems manifested in arthritis and asthma. It helps fight the action of free radicals against cholesterol, thus promoting heart and cardiovascular health. However, if you are taking medicines for cholesterol, please consult your doctor before consuming grapefruit, because it may cause certain side effects if consumed with those drugs. The lycopene content in grapefruits is also shown to have anti-cancerous properties, which help in the prevention of various types of cancer like breast cancer, prostate cancer. A study conducted on the effects of grapefruit on cancer patients showed that it helped in treating cancer to a certain extent. Consumption of grapefruit juice helps reduce leg swelling and water retention, in pregnant women.

Despite the several benefits, avoid consumption of large amounts of grapefruit or grapefruit juice. As per studies based on drug interaction effects of grapefruit, it is shown that certain compounds are present in this fruit that inhibit specific enzyme activities. This, in turn, enhances the potency of various therapeutic drugs, leading to overdose effects. Taking this into consideration, those who are currently on medication should consult the concerned physician before taking grapefruit or its products.
