5 Health Benefits of Grapefruit

5 Health Benefits of Grapefruit

Feb. 12th, 2022

Grapefruit is a large citrus fruit that is known for its sweet and sour taste that many people describe as bittersweet. Grapefruit resulted as a cross between a pomelo and an orange, where it originated as an accidental hybrid.1 Grapefruit got its name because it grows in clusters, similar to grapes.

Aside from its unique, delicious taste, grapefruit provides many health benefits. Here are 5 health benefits of grapefruit that you can get from adding this fruit into your diet.

Grapefruit is Loaded with Nutrients

One of the health benefits of grapefruit is that it contains nutrients and antioxidants that can improve your overall health.

Here are some of the nutrients found in one medium-sized grapefruit:

  • Vitamin C. Vitamin C aids the body in many ways, from collagen production to lower blood pressure to preventing iron deficiency.2 One half of a grapefruit contains almost half of the recommended daily intake of vitamin C for adults.
  • Vitamin A. Vitamin A supports vision health, the immune system, and reproductive health.3
  • Potassium. Potassium is an electrolyte that is involved in many body processes, from heart function to muscle contraction to nerve transmission.4
  • Fiber. Grapefruit is high in fiber. Half of a grapefruit contains 2 grams of fiber and the recommended daily intake is 25 grams. Fiber supports digestion and lowers your risk of diabetes and heart disease.5
  • Antioxidants and Phytochemicals. Antioxidants help reduce inflammation in the body. Phytochemicals have been found to help improve blood pressure. Multiple studies suggest a link between the antioxidants and phytochemicals found in grapefruit and a decreased risk of cancer.3

Grapefruit is Hydrating

Most of a grapefruit’s weight comes from the water it holds.6

There’s about four ounces of water in just one half of a medium-sized grapefruit, which is close to 90% of its weight. Consuming four ounces is about half a glass of water.

Eating foods with a large water content is helpful when it comes to staying hydrated. Hydration is important because your cells, tissues, and organs all need water to properly function.7

Grapefruit Can Boost Immunity

As with many citrus fruits, grapefruit is loaded with vitamin C which has been proven to boost the immune system. Vitamin C is an anti-inflammatory, antiviral, and antibacterial, all of which help your cells fight off viruses.8

Grapefruit also contains zinc, which is known to be an immune system booster.9 In one study, researchers concluded that the intake of zinc and vitamin C shortened the durations of respiratory infections, including the common cold.10

Grapefruit Aids in Healthy Skin

The vitamin C that grapefruit contains is essential for collagen production. Collagen is a protein that aids in skin health and helps with healing wounds.11 Vitamin C also allows the body to replenish hyaluronic acid, which enables you to produce more collagen. This chain reaction keeps the skin youthful and healthy.

Exposing your skin to the sun produces free radicals, which can cause tissue damage to the skin. However, vitamin C is an antioxidant that works to remove free radicals and can ultimately help protect the skin against sun damage and signs of aging.13

Grapefruit May Improve Heart Health

Many of the nutrients in grapefruit can aid in heart health.

The American Heart Association recommends that people increase their daily intake of potassium, as it can prevent high blood pressure and health concerns, such as heart attack and heart failure, that come with it.14 One small grapefruit alone contains 278 milligrams of potassium, which is about 6% of an individual’s daily recommended potassium.1

Grapefruit is free of cholesterol and saturated fat, which makes it a healthy snack for the heart. Phytonutrients found in grapefruit, including carotenoids and polyphenols, also support heart health.15

How to Add Grapefruit Into Your Diet

Although most people enjoy grapefruit simply by cutting it in half and eating it by itself, there are many recipes that incorporate this fruit. Here are some ideas to add grapefruit into your meals:

  • Eat half or a whole grapefruit as a snack
  • Add grapefruit slices to your yogurt or make a yogurt parfait
  • Make grapefruit muffins
  • Make a jam or glaze with grapefruit
  • Slice grapefruit and add it to a salad
  • Try fresh grapefruit juice
  • Add grapefruit to your water or lemonade
  • Broil grapefruit and top it with yogurt, honey, and cinnamon for a sweet treat
  • Make a fruit salad and include grapefruit
  • Try fresh grapefruit sorbet or popsicles
  • Make grapefruit bars with a shortbread crust
