Grapefruits are sour fruits full of health-inducing vitamins and minerals. Grapefruits can be pink, red, or white.
Half a grapefruit contains the following nutrients:
- 52 calories
- 13.11 g carbohydrate
- 2.0 g fiber
- 27 g calcium
- 11 g magnesium
- 166 g potassium
- 38.4 g vitamin C
The flavonoids in grapefruits can help protect against some cancers, inflammation, and obesity.
A review study suggests the compounds called furanocoumarins found in grapefruits can help protect against oxidative stress and tumors and may support healthy bones.
Some research from this review suggests that grapefruit furanocoumarins may have anticancer properties, which may be especially effective against breast cancer, skin cancer, and leukemia. Researchers still need to carry out more studies on animals and humans to confirm these properties.
People may wish to see a doctor before adding grapefruit to their diet, as it can interact with certain medications.
