Whether you prefer to consume them whole or in juices combined with other citrus fruits or just other fruits, the fact is that by consuming enough grapefruit, you are providing your body with the following five benefits:
Antioxidant-rich
The grapefruit contains nutrients and plant compounds that exhibit antioxidant properties. In particular, they are a good source of beta-carotene, which is converted in the body into vitamin A and reduces the risk of chronic diseases such as macular degeneration. Grapefruit is also a good source of lycopene, which is associated with a reduced risk of cancer.
Contributes to heart health
Grapefruit is rich in potassium and fiber, as well as antioxidants that help regulate blood pressure and cholesterol levels. Studies in humans have shown the beneficial role that grapefruit, and red grapefruit in particular, can play in improving cholesterol levels, particularly in those with atherosclerosis.
In 2012, the American Heart Association even published a report recommending that a diet high in certain flavonoids, compounds found in citrus fruits and grapefruit, can reduce the risk of stroke in women.
Helps with weight loss
There is some evidence to suggest that eating grapefruit can help you lose weight. A 12-week Japanese study looked at the effects of eating grapefruit and a placebo and found a significant reduction in weight as well as blood glucose levels in those who consumed half a grapefruit before meals.
Regulates blood sugar
Animal studies have examined the beneficial role that grapefruit juice may play in reducing blood glucose levels and improving insulin resistance. This is further supported by the higher intake of fruits and green vegetables being associated with a significantly reduced risk of type 2 diabetes mellitus.
Improves brain function
There is research evidence on the role of flavonoids in nutrition and enhancing memory and cognitive function, as well as in the prevention of neurodegenerative conditions.
Despite the multiple health benefits of grapefruit, the UK's National Public Health Agency advises against combining fresh grapefruit or grapefruit juice with certain drugs, as it has been shown to reduce their breakdown and elimination, which can lead to increased levels of the drugs in the blood.
These include statins, calcium channel blockers, immunosuppressants and some anti-cancer drugs. Consult your doctor if you are taking prescription drugs before consuming grapefruit or grapefruit juice.
