A diet rich in oily fish helps prolong life in people with prostate cancer. Regular consumption of omega-3 fatty acids reduces the risk of death from the disease by 34 to 40%, according to data from a study by the Harvard School of Public Health in Boston. It is also estimated that those consuming the highest amounts of saturated fat are twice as likely to not survive the disease. Nearly 40,000 cases of prostate cancer are diagnosed each year in the UK, 10,000 of which are fatal. In Bulgaria, about 1,530 new cases of prostate cancer are added every year. Age has been identified as a risk factor for prostate cancer. Heredity also plays a role. Men with a family history of the disease are about 2 times more likely to develop it. The way you eat is also essential. The American study included 525 men with an average age of 70 with prostate cancer. During the research period, the participants were surveyed about their eating habits, including the consumption of different types of fat.
