Simply hearing the name of this juicy fruit, or seeing it in the produce aisle, can make our palates cringe and our face scrunch up. Although somewhat sour and bitter taste of grapefruit may not cater to all taste buds, its red, pink, and white pulp varieties are full of vitamins and minerals, which add on to its many health benefits. The moon-shaped fruit is not only rich in vitamin C, but the health benefits of grapefruit are many— from our immune system to our metabolism.

Grapefruit grows in clusters just like grapes, hence the name. It was first discovered in South America. It is a natural hybrid between orange and pomelo which accounts for its large size and tangy flavour.

What’s the best part? While grapefruits are normally in season from winter through early spring, you can experience the health benefits of grapefruit all year round.

The health benefits of grapefruits are many and practically unmatched by any other fruit. A glass of chilled grapefruit juice can boost your levels of vitamin C – this gives grapefruits a superior place amongst various citrus fruits. This fruit is packed with the benefits derived from various nutrients and vitamins, including potassium and lycopene. Along with these, it also contains calcium, sugar and phosphorous. Talking about its culinary value, it is regarded as a superb appetizer, and is regularly included for breakfast as a refreshing and energizing start to the day.

Lauren Blake, a registered dietician at the Ohio State University Wexner Medical Center, believes we should opt for the pink- and red-colored varieties to reap the most benefits of this cancer-fighting fruit. “Pink and red colored grapefruit contain the antioxidant lycopene. Lycopene appears to have propertied that help fight free radicals, which are compounds that can damage cells.”

1.  An Incredible boost to the Immune System

We all know that any fruit which is rich in vitamin C will strengthen and support our immune system. Vitamin C in combination with other micronutrients provides good and regular nourishment to our body. Maintaining the level of vitamin C in our body reduces the severity of cold symptoms, acting as a natural antihistamine. This helps in controlling allergies, since it reduces histamine levels. “Grapefruit is abundant in vitamin C which help supports the immune system. Half of a grapefruit provides about 78 percent of your recommended daily intake of Vitamin C,” Blake said.

2. Kidney Stone Prevention

One of the great health benefits of grapefruit is that it helps in preventing kidney stones. Kidney stones are usually a buildup of calcium. If developed these stones must either pass through the urethra or broken up medically. The greatest benefit can be reaped through drinking up to a liter of grapefruit juice daily.

3. Helps in Weight Loss

Have you ever heard of the grapefruit diet? Also known as the Hollywood Diet, the grapefruit has been around for decades, and apparently holds some merit. A study led by Dr. Ken Fujioka found that including grapefruit or grapefruit juice into your daily diet does help in weight loss. For the study, 100 participants were separated into 3 groups with varying grapefruit and grapefruit juice intake levels. In the end, participants who ate 1/2 grapefruit with each meal lost 3.6 pounds on average while those drinking grapefruit juice 3 times daily lost 3.3 pounds on average.
