Men who eat over 10 portions a week of tomatoes have an 18 per cent lower risk of developing prostate cancer, new research suggests.
With 35,000 new cases every year in the UK, and around 10,000 deaths, prostate cancer is the second most common cancer in men worldwide. Rates are higher in developed countries, which some experts believe is linked to a Westernised diet and lifestyle.
David Neal of the Department of Oncology, together with researchers at the Universities of Bristol and Oxford, looked at the diets and lifestyle of 1,806 men aged between 50 and 69 with prostate cancer and compared them with 12,005 cancer-free men.
The NIHR-funded study, published in the medical journal Cancer Epidemiology, Biomarkers and Prevention, is the first study of its kind to develop a prostate cancer ‘dietary index’ which consists of dietary components – selenium, calcium and foods rich in lycopene – that have been linked to prostate cancer. Men who had optimal intake of these three dietary components had a lower risk of prostate cancer.
