Here are the 7 health benefits of grapefruit.

1.     Grapefruits can help keep your eyes healthy.

Grapefruits are rich in vitamin A with 53 percent of the recommended need per serving. Vitamin A is known for improving your eyesight and preventing night blindness and macular degeneration from developing as we age.

2.     Grapefruits can help individuals fight infections.

A large grapefruit has 120 percent of the vitamin C daily requirements. Vitamin C is a potent natural water-soluble antioxidant that helps the body develop resistance against infectious agents and eliminates cancer-causing free radicals in the body.

3.     Grapefruits are great for the hair and skin.

Adequate vitamin C intake does not only improve the immune system, can also create and maintain collagen, an important protein found in hair and skin. In addition, the vitamin A in grapefruits also keeps the hair moisturized through increased sebum production.

4.     Grapefruits could help improve digestive health.

Grapefruits are a great source of fiber. Dietary fiber helps prevent constipation, making one’s bowel movement easier to accomplish.The daily recommended dietary fiber intake for men and women are 38 grams and 25 grams, respectively.

Also, grapefruit juice taken before all three meals of the day can work as a suitable probiotic and digestive enzyme and will relieve excess flatulence and stomach discomfort.

5.     Grapefruits can help maintain a healthy blood pressure.

Grapefruits are loaded with potassium and a low content of sodium. One large grapefruit contains an outstanding 311 milligrams of potassium, compared to zero milligrams of sodium. This helps the blood vessels relax and maintains proper blood pressure.

6.     Grapefruits can help your slumber.

Grapefruits have been known to help an individual sleep with its high content of magnesium, which is a mineral that is directly linked to improving the quality, duration, and tranquility of sleep. Grapefruits also help regulate the metabolism, to help reduce sleep disorders and the occurrence of insomnia.
