Grapefruit, sometime referred to as shaddock is a citrus fruit. It comes in many varieties which are determined by colour and the most popular varieties cultivated today are red, white, pink and hues. Like bananas, grapefruits are available throughout the year except two varieties namely Florida and Texas.

These two are seasonal and available between the months of November – June. Grapefruits have different tastes – acidic, bitter sweet and sugary. The essential nutrients of grapefruit are vitamins A and C, potassium, calcium, fibre, iron, magnesium, manganese, folic acid and phosphorous.

Health benefits of grapefruits

Cardiovascular disease

Grapefruit contains the powerful combination of potassium, fibre, lycopene, and vitamin C. All these nutrients helps our body to maintain a healthy heart. It regulates the cholesterol levels and reduces the risk of heart disease.

Consumption of grapefruit can reduce LDL cholesterol (bad cholesterol). Red grapefruit influences blood lipid levels and reduces triglycerides, a form of cholesterol which is a primary cause for heart disease. But if you are taking medications for any heart issue, then get your doctor’s advice to consume grapefruits.


Helps digestion

Grapefruit juice helps to promote digestion. Eating the fruit along with the spongy white tissue is important to get extra fibre that aids bowel movements. It hence helps your digestion to be smooth.

Though it has a sub-acid taste, its juice has an alkaline reaction after digestion that helps in the treatment of acidity in the digestion system.

Weight loss

Just eating half a grapefruit or its juice before every meal helps in weight reduction, and hence works well for breakfast. As already discussed, grapefruit is loaded with fibre that keeps you free of hunger for a longer time. The compounds present in grapefruit, reduces insulin levels converting food into energy swiftly without converting it into fat. Grapefruit is hence an ideal choice of snack for those who are looking to shed a few pounds.
