Likewise, there is also evidence based on different scientific studies that ensure that vitamin D plays a key role in reducing the risk of different types of cancer, such as colorectal cancer.
Among all these research works we can highlight an ecological study carried out by the brothers Cedric and Frank Garland. This analysis was based on colon cancer mortality rates relative to geographic variations in annual solar radiation in the United States.
The results of this study showed that the incidence of all types of cancer and cardiovascular disease did not vary significantly from participants who received a placebo.
However, death rates for all types of cancer decreased by up to 25%. “Cancer incidence rates were 25% lower for black participants and significantly lower 25% for those with a BMI <25 kg / m2,” the study adds.
Therefore, there is moderately strong evidence that the administration of vitamin D is effective in reducing the risk of cardiovascular disease and also a large number of pathologies with high mortality.
