A handful of walnuts a day could help keep prostate cancer at bay.
Snacking on the nuts can cut the size of tumours and slow their growth, research shows. Although the experiments were carried out on mice, the researchers believe they are relevant to humans. They advise that men add around 14 shelled nuts to their diet for optimal health.
Prostate cancer is the most common cancer among men and the second highest killer after lung cancer. Some 35,000 Britons are diagnosed with it each year, and 10,000 die. Although the causes of the disease are not entirely clear, it is known to be linked to diet, and tends to be most common in those who eat fatty meals low in fruit and vegetables.
