Be careful with dairy products!

THE ESSENTIAL

  • Calcium intake can be non-dairy, through consumption of seeds, nuts, legumes and other vegetables, fruits or grains.
  • In men over 50, prostate cancer is the most frequently diagnosed disease in France, with more than 71,000 cases per year.

8,000 dead. This is the sad annual rating of prostate cancer in France in men according to Public Health France, making it the third deadliest cancer after lung and colon cancer. According to Vidal’s website, there are three main risk factors for prostate cancer: age (in men, most cases are diagnosed around the age of 70), family history, and ethnicity, as this cancer is more common in men of African descent, northern Europeans, and northern Americans. Then we find the consumption of certain products such as tobacco, cold cuts or dairy products.

A link between dairy consumption and prostate cancer risk

A new study published in the journal The American Journal of Clinical Nutrition also points to this last risk factor. According to researchers at Loma Linda University in California, men who regularly consume dairy products such as milk, but also yogurt or cheese, are more likely to develop prostate cancer than men who don’t.

To reach this conclusion, the scientists followed more than 28,000 men who had no signs of cancer at the start of the study. The participants were divided into two groups based on their diet: members of the first group did not eat dairy products and the second group consisted of men who consumed it regularly.

These participants were followed by the researchers for more than seven years. At the end of this period, 1,254 of them, or almost 4.5%, had prostate cancer or an incident related to this disease. 190 of these cases were at an advanced stage.

The risk increases with altitude

But there were also differences in the risk of developing prostate cancer among those who ate milk. In detail, men who consumed about 430 grams per day had a 25% higher risk of developing this pathology compared to men who consumed only 20.2 grams.

“The study data provided little evidence of an association between calcium intake and prostate cancer incidence. Dairy products, on the other hand, are causally associated with prostate cancer risk,” say the authors. So it’s not the calcium itself, but the dairy products that scientists are skewing. The reason given was the content of sex hormones in cow’s milk. But for now, this is just a hypothesis for other studies to test.
