BEIJING, Dec. 27 (Xinhuanet) -- Eating two grapefruits a day for a fortnight may have help those with gum disease, a study suggests.
Researchers at Friedrich Schiller University in Germany found eating grapefruit daily increases the serum vitamin C level and relieves periodontitis.
On average, smokers' vitamin C level was 29 percent lower than that for non-smokers. Eating two grapefruits a day raised vitamin C plasma levels for all those who consumed it, it said.
Vitamin C in the periodontitis patients was below the normal level.
Each grapefruit contains approximately 92.5 mg of vitamin C.
Vitamin C-rich fruits and vegetables include oranges, grapefruit, tomatoes, pineapple, broccoli, cantaloupe, cauliflower, asparagus, and strawberries.
However, the researchers suggested that those consuming acidic fruits should not brush their teeth immediately after consuming the grapefruit because acidic citrus juice can weaken tooth enamel making it susceptible to erosion.
The findings are published in the British Dental Journal.
