Grapefruit is an excellent source of vitamin C, a vitamin that helps to support the immune system. Now more than ever, its important to ensure that our immune system is at its peak.
Vitamin C-rich foods like grapefruit may help reduce cold symptoms or severity of cold symptoms - over 20 scientific studies have suggested that vitamin C is a cold-fighter.
Vitamin C also prevents the free radical damage that triggers inflammation, and therefore also reduces the severity of inflammatory conditions, such as asthma, osteoarthritis, and rheumatoid arthritis.
Free radicals can oxidize cholesterol. This leads to plaque deposits which build up in the heart and may rupture causing heart attacks or stroke. Vitamin C is therefore beneficial to promoting cardiovascular health.
Owing to the multitude of vitamin C's health benefits, it is not surprising that research has shown that consumption of vegetables and fruits high in this nutrient is associated with a reduced risk of death from all causes including heart disease and stroke.
