The link between dairy intake and cancer risk is controversial, as dairy contains bioactive compounds that have both positive and negative effects on carcinogenesis.
It has been suggested that the possible protective effect against some cancer may be related to its high content of some nutrients such as calcium; while the negative effects would be linked to the activation of a factor called IGF-1 (insulin-like growth factor 1).
With this in mind, we can understand why dairy consumption may in turn be associated with a decreased risk of some cancers such as colonrectal, and on the other hand, with an increased risk of prostate cancer and ovarian cancer.
Given these results, there is no need to stop taking dairy if you like it and you feel good, because these negative associations are linked to high dairy consumption.
If you like dairy and tolerate it, you can take 1-2 servings daily (1 serving equals 2 yogurt or 1 cup milk or cheese 60g).
Furthermore, consider taking yogurts (best natural and no sugar added) and other fermented milk to obtain their microorganisms content benefits.
