7 Health Benefits Of Grapefruit
1. It’s great for your immune system
of all that glorious nutrient density: grapefruits are a good source of vitamins A, C, and E—a trifecta that works together to keep the immune system up. (Specifically, one whole grapefruit has 77 mg of vitamin C—more than what you’d get in a large orange.) So you know those times of the year when everyone in your office seems to be sick? (Um, like right now?) It’s the perfect time for some grapefruit.
2. Eating grapefruit regularly is linked to higher nutrient consumption
One study found that women who ate grapefruit had a higher intakes of vitamin C, magnesium, potassium, dietary fiber, and improved diet quality. “Grapefruit may provide a healthful option for adults striving to meet fruit recommendations,” the study concludes. However, they weren’t only eating grapefruit, so it’s hard to tell how much the grapefruit made an impact on those overall levels. But the association itself is certainly promising.
3. It could help prevent diabetes
There’s evidence that eating grapefruit—which is moderate on the glycemic index scale—can help keep insulin levels even, protecting against type 2 diabetes. “Greater consumption of blueberries, grapes, apples, bananas, and grapefruit were significantly associated with a reduced risk of type 2 diabetes,”reads one large 2013 study. “Our findings suggest that there is significant heterogeneity in the associations between individual fruits and risk of type 2 diabetes.”
4. It could help keep fat from building up in artery walls
There’s evidence—at least in mice—showing that naringin (a flavonoid in grapefruit) can help prevent atherosclerosis, when plaque and cholesterol build up in your arteries. Again, this is just a mouse study, but grapefruit certainly could be worth adding to a heart-healthy lifestyle.
5. It’s high in antioxidants
Grapefruit is also a good source of antioxidants, which help reduce inflammation and fight damage caused by free radicals in the body. Even grapefruit peels are high in antioxidants, so don’t just enjoy the refreshing, vibrant meat and juice of the fruit; use the peels as zest in various dishes, such as poultry or in baked goods.
6. It keeps you hydrated
Grapefruits are 88 percent water (one whole fruit has 216 grams of the stuff!) making them a pretty stellar way to stay hydrated in addition to your regular S’well bottle habit. While grapefruit juice is a popular breakfast beverage, it’s more beneficial to the body to eat the fruit so you’re also getting fiber.
7. Grapefruits help keep bones strong
Potential risks of eating grapefruit
Okay, so it’s pretty obvious that eating grapefruit on the reg is hugely beneficial to the body. However, there’s a catch. Grapefruit can interfere with an enzyme that metabolizes a wide variety of drugs, allowing more of the drug to make its way into the bloodstream and increasing the risk of side effects and even overdose. This isn’t a niche issue; a 2012 study found that 85 medications ranging from OTC antihistamines to prescription blood pressure medications could be affected by grapefruit. “Taking one tablet with a glass of grapefruit juice is like taking five tablets with water,” a pharmacologist told NPRin 2012.
