We already told you regarding it nearly ten years ago, low exposure to sunlight seems to significantly increase the risk of developing prostate cancer, and this disease is all the more widespread the farther away the place of residence is. the equator (read “Prostate cancer: is it necessary to be cured?” and “Prostate cancer: is it as serious as they say?”). Researchers at the famed nonprofit Cedars-Sinai Medical Center in Los Angeles have taken a closer look at this theory by looking at the differences in the way the bodies of European American men and American American men look. american descent manage vitamin D.
African origins that promote vitamin D deficiency
African-American men, with darker skin, are more likely than European American men to develop prostate cancer and are twice as likely to die from the disease. They also suffer from more aggressive prostate cancers and at a younger age than lighter-skinned European American men.. Large-scale studies have shown that differences in access to health care do not fully explain this disparity, thus pointing to biological differences that need to be better understood.
« The ancestors of African American and European American men adapted to the climates from which they originated and men of African descent retain higher levels of melanin in the skin to protect once morest strong sunlight “, explains Moray Campbell, lead author of the study and biologist specializing in hormone-dependent cancers. ” However, since melanin acts as a natural sun protection, dark-skinned people must expose themselves three to five times longer compared to those with fair skin to synthesize the same amount of vitamin D. For this reason, their descendants who live in the United States and receive fewer hours of sunlight per year than in African countries are often deficient in vitamin D “, he details.
However, continues Moray Campbell, vitamin D stimulates cell maturation (it helps the oldest cells in our body to “die” and the youngest to develop) and without a sufficient level of vitamin D, to make them mature, the cells of a tumor multiply even more uncontrollably and rapidly. For researchers, these data mean that in the future, nutritional recommendations might be made for men of African descent or with dark skin encouraging them to pay particular attention to their vitamin D levels.
In the meantime, the team also plans to examine the possible role of vitamin D in explaining disparities in other hormone-dependent cancers, such as breast.

Unhealthy diet increases risk of aggressive tumor
Another study, published this time in the British Journal of Urology Internationalrevealed that while eating a healthy diet does not appear to reduce the risk of prostate cancer in general, eating an unhealthy diet may, on the other hand, increase the risk of developing aggressive prostate cancer.
By evaluating the diets of 15,296 Spanish men followed for seventeen years, the researchers classified the eating habits of the participants into three categories:
- western diet (consisting of high consumption of high-fat dairy products, processed meat, refined grains, sweets, caloric beverages, ready meals and sauces, and low consumption of low-fat dairy products and whole grains );
- careful diet (high consumption of vegetables, fruits, whole grains, fruit juices, low-fat dairy products);
- mediterranean diet (high consumption of fish, vegetables, legumes, boiled potatoes, fruits, olives, vegetable oil, and low consumption of fruit juice).
Men with conservative and Mediterranean diets had no lower risk than average to develop prostate cancer. In contrast, a detrimental effect was observed with the Western diet which seemed to favor aggressive tumors. So much so that, according to the researchers, Avoiding unhealthy eating habits might be the ” best nutritional strategy » to prevent aggressive prostate cancer.
