Go Full Fat When it Comes to Dairy Products

Standard health advice is to look for low-fat or no-fat products, including dairy. But that advice changes when it comes to conceiving. One or two daily servings of full-fat dairy products seems to help protect against infertility. Consuming low-fat dairy products actually does the opposite. In a study of more than 18,000 women, researchers found that women who had one or more daily servings of full-fat dairy products daily were 27 percent less likely to be infertile than those who had less than one serving a week. However, women who ate two or more servings of low-fat dairy daily were almost twice as likely to be infertile. Just drinking one 8-ounce glass of whole milk daily cut the risk of infertility by 50 percent. Why the different results from the full-fat and low-fat products? Possibly because estrogen and progesterone in the milk attach to the fat globules. Skimming the fat skims off those hormones, leaving behind others that are not conducive to conception, such as some androgens, insulin-like growth factor-1, and prolactin.
