5-a-day keeps oral cancer away

A major review of 16 studies has revealed that increasing the amount of fruit and vegetables you eat can reduce the risk of mouth (oral) cancer. The research showed that each additional serving of fruit reduced the risk of mouth cancer by 49 per cent and each additional serving of vegetables showed a 50 per cent reduction in mouth cancer. Some fruits were more effective than others; citrus fruits reduced the risk by a whopping 62 per cent. Even if your current intake is low, eating just one extra serving of fruit or vegetables per day could significantly reduce the risk of mouth cancer as well as lowering the risk for heart disease, stroke, high blood pressure and obesity.
