A 30-year follow-up survey conducted by the Karolinska Institutet in Sweden shows that people who regularly eat fish do not easily develop prostate cancer.
According to a report in the Swedish daily, the researchers of the medical school conducted a 30-year follow-up survey of 6,000 men in Sweden from 1967 to 1997. The results showed that people who never eat fish have a two to three times higher risk of developing prostate cancer than those who regularly eat fish. For 30 years, 466 of these people surveyed had prostate cancer and 340 died of the disease.
According to preliminary analysis, researchers believe that an omega-3 fatty acid contained in the fish has the effect of preventing prostate cancer. In particular, fish such as salmon, which contains more fat, contain more omega-3 fatty acids. Adam Volcker, professor of epidemiology at Karolinska Institutet, who participated in the study, said that he and his colleagues plan to conduct more in-depth studies to further clarify why eating more fish can prevent prostate cancer.
Prostate cancer is one of the most common cancers among men in Sweden. More than 5,000 people in the country suffer from this disease each year. It is believed that 10% of patients are affected by genetic problems and the rest are due to other reasons.
