Bioactive compounds that help protect cardiovascular health.
According to the U.S. Centers for Disease Control and Prevention (CDC), citrus fruits like grapefruit provide large amounts of vitamin C and flavonoids—compounds that help reduce oxidative stress in the body.
Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard University School of Public Health (USA), said that diets rich in citrus fruits are associated with a lower risk of cardiovascular disease and stroke.
The mechanism is explained as follows: flavonoids such as naringin in grapefruit help reduce oxidative stress, thereby limiting damage to blood vessel walls and improving blood circulation.
Positive effects on gut health and weight.
Grapefruit is rich in soluble fiber, especially pectin – an ingredient that helps nourish beneficial gut bacteria. According to the U.S. National Institutes of Health, fiber not only improves digestion but also helps regulate blood sugar.
According to Dr. Roxana Ehsani (American Academy of Nutrition and Dietetics), eating grapefruit before meals can help reduce appetite by increasing feelings of fullness, thereby aiding in weight management.
The study, published on PubMed, also showed that adding grapefruit to the diet can help reduce overall energy intake without increasing feelings of hunger.
How to eat grapefruit in a way that's good for your health?
Experts recommend eating fresh grapefruit instead of juice to retain its beneficial fiber content. A serving of grapefruit (about half a fruit) can be included in a daily diet, according to the Mayo Clinic.
For those with sensitive stomachs, it's best to avoid eating acidic fruits on an empty stomach. Additionally, limiting added sugar or salt helps preserve the nutritional value of the fruit.
Notably, according to the U.S. Food and Drug Administration, grapefruit can interact with certain medications, so those undergoing medical treatment should consult their doctor before consuming it regularly.
