Grapefruit is good for your gums
Tucking into grapefruit on a regular basis could help to fight gum disease which is the biggest cause of teeth loss in adults.
Dentists found that people with gum disease who ate two grapefruits a day for a fortnight showed significantly less bleeding from the gums.
It is thought that vitamin C found in the fruit travels in the bloodstream to the site of the infection to fight off bacteria.
The study of 58 people - all with chronic gum disease - found that eating grapefruits had a positive effect on both smokers and non-smokers. Smoking is known to increase the risk of gum disease.
At the start of the two-week study, almost all those taking part had low levels of vitamin C in their blood plasma.
On average, the smokers' vitamin C level was 29 per cent lower than that of the nonsmokers.
Eating two grapefruits a day raised vitamin C plasma levels for all those in the study. In smokers, the level almost doubled, but because they started from a lower baseline, their average vitamin C level remained lower than the nonsmokers.
Vitamin C 'promotes healing'
The research, by Friedrich Schiller University in Germany, is published in the British Dental Journal.
Experts say the study reinforces previous research that if you have enough vitamin C in your diet, it tends to promote healing. Each grapefruit contains about 92.5 mg of vitamin C.
Other sources of vitamin C - including oranges, tomatoes, pineapples, broccoli, cantaloupe, cauliflower, asparagus, and strawberries - may be used instead of grapefruit.
