Grapefruit, scientifically known as Citrus paradisi, is a citrus fruit that originates from a cross between the pomelo and the orange. Its consumption can bring a range of health benefits, including supporting the normal functioning of the immune system, helping to maintain skin health, and aiding weight management.
The fruit can present with skin and flesh of varying colours, including yellow, pink, red, and orange.
Health benefits of grapefruit:
Boosts the immune system
Grapefruit is rich in vitamin A, vitamin C, and antioxidant and anti-inflammatory compounds that contribute to the normal functioning of the immune system and help protect cells against damage caused by free radicals.
Vitamin C also plays an important role in supporting the body’s defences.
2. May help combat certain bacteria
Grapefruit contains bioactive compounds with antimicrobial properties, including flavonoids, saponins, and tannins.
These compounds have demonstrated activity against certain bacteria, including Escherichia coli, Salmonella Typhimurium, and Staphylococcus aureus. However, effects observed in laboratory studies do not mean that consuming the fruit can replace medical treatment for a bacterial infection.
Helps prevent premature ageing
Grapefruit is rich in vitamin C, a nutrient that participates in the production of collagen, a protein essential for skin firmness and elasticity.
Vitamin C also plays an important role in supporting the body’s defences.
In addition, its antioxidant compounds help protect cells against damage caused by free radicals, contributing to the maintenance of skin health.
May contribute to cell protection
Grapefruit contains various antioxidant compounds, including flavonoids, limonoids, and furanocoumarins, which have been studied for their antiproliferative properties and their capacity to protect cells against oxidative stress.
Some laboratory studies suggest a possible action of these compounds against the development of certain tumour cells. However, further studies in human subjects are needed to confirm these effects.
Contributes to bone health
Grapefruit contains bergapten, a natural compound found in various plants and also in the juice of this fruit.
Some studies indicate that this compound may be linked to processes of bone regeneration and the maintenance of bone mineral density. However, more evidence is needed to determine its effects in the prevention of conditions such as osteoporosis.
May assist with weight management
Grapefruit is a low-calorie fruit with a high water and fibre content — nutrients that can help increase the feeling of fullness and reduce the urge to eat between meals.
Grapefruit contains bergapten, a natural compound found in various plants and also in the juice of this fruit.
Including it in a balanced diet can therefore be useful for those seeking to manage their weight. However, no fruit on its own causes weight loss. Weight reduction depends on a combination of factors, including diet, physical activity, and energy balance.
May help control blood sugar levels
Grapefruit contains soluble fibres, such as pectin, which can slow the absorption of carbohydrates in the intestine.
Furthermore, certain compounds present in the fruit, such as flavonoids and terpenoids, have been studied for their possible effects on glucose metabolism.
As such, grapefruit can form part of a balanced diet for people who need to manage blood glucose levels. However, it does not replace medication or the recommended treatment for diabetes.
May contribute to cholesterol management
Grapefruit contains fibre and antioxidant compounds that may contribute to fat metabolism and the maintenance of adequate cholesterol levels in the blood.
Soluble fibres can also help reduce the intestinal absorption of cholesterol and promote its elimination through bile acids.
9. Helps maintain hydration
Grapefruit is composed of approximately 88% water, contributing to daily fluid intake.
It can therefore be a good option to complement hydration, particularly during periods of intense heat. However, water should remain the primary source of hydration, especially during prolonged or intense physical activity.
