<p>According to a new study, a combination of high doses of Vitamin D, omega 3 fatty acids, and a simple home strength training program (SHEP) has been shown to reduce a cumulative reduction by 61 per cent in cancer risk for healthy adults age 70 and older.</p>.<p>This was the first study to test the combined benefit of three affordable public health interventions for the prevention of invasive cancers. Mechanistic studies have shown that vitamin D inhibits the growth of cancer cells. Similarly, omega-3 may inhibit the transformation of normal cells into cancer cells, and exercise has been shown to improve immune function and decrease inflammation, which may help in the prevention of cancer.</p>.<p>The results show that all three treatments (vitamin D3, omega-3s, and SHEP) had cumulative benefits on the risk of invasive cancers. Each of the treatments had a small individual benefit but when all three treatments were combined, the benefits became statistically significant, and the researchers saw an overall reduction in cancer risk by 61 per cent.<br /> </p>
