It is already known from previous studies that vitamin D and omega-3 fatty acids can inhibit the growth of cancer cells. Sport and exercise, on the other hand, support the immune system and counteract inflammation, which can also prevent cancer. In the present study, the Swiss researchers therefore examined how a combination of these three measures protects against cancer. It was found that all three measures individually had a small protective effect, but in combination they worked much better and were able to reduce the risk of cancer in the elderly by 61 years. The study results are published in the journal Frontiers in Aging.
Cancer is the second leading cause of death in adults in Europe after cardiovascular disease. The risk of getting sick increases with age. As part of the three-year study, scientists at the University Hospital of Zurich therefore wanted to find out whether there were easy ways to reduce personal risk of disease.
2,157 people from five European countries took part in the study. They were divided into eight groups to analyze the individual and combined effects of vitamin D, omega-3 fatty acids, and exercise. Only one group received 2,000 international units of vitamin D per day, 1 gram of omega-3 fatty acids per day, and simple home exercise three days per week. The remaining participants received only one or two of the measures, one group was treated with placebo only.
