According to the WHFood’s website, grapefruit is rated one of the worlds’s healthiest foods. Grapefruit is an excellent source of vitamin C, a vitamin that helps to support the immune system. 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 the inflammatory cascade, and is therefore also associated with reduced severity of inflammatory conditions, such as asthma, osteoarthritis, and rheumatoid arthritis. As free radicals can oxidize cholesterol and lead to plaques that may rupture causing heart attacks or stroke, vitamin C is 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, stroke and cancer.
Prevent Kidney Stones
Want to reduce your risk of calcium oxalate kidney stones? Drink grapefruit juice. A study published in the British Journal of Nutrition found that when women drank 1/2 to 1 liter of grapefruit, apple or orange juice daily, their urinary pH value and citric acid excretion increased, significantly dropping their risk of forming calcium oxalate stones.
Fresh is always best! Juicing citrus fruits is much more beneficial than buying the boxed version. I eat a lot of citrus fruits for their nutritional values.
Drug Reaction: Check with your healthcare practitioner about consuming grapefruit juice if you’re taking pharmaceutical drugs. Certain pharmaceutical drugs combined with grapefruit juice become more potent.
