If you're trying to get pregnant, you may want to give up the low-fat diet for awhile and take a trip to Ben and Jerry's. A recent study found that women who ate one or more servings of high-fat dairy foods--such as ice cream--every day decreased their risk of infertility from ovulatory disorders by 25 percent.
The opposite is also true, according to the findings published in the journal Human Reproduction. Researchers found that women who ate two or more servings of low-fat dairy foods per day increased the risk of anovulation (lack of ovulation) by 85 percent.
Several factors may be responsible for the dairy fat/fertility link, including high-fat dairy contains fertility-essential vitamin A from butterfat and helps make sex hormones that balance the chemicals in the reproductive system. Another possibility is that low-fat dairy products contain added whey protein, which is suspected of having a testosterone-like effect.
The bottom line is that if you're trying to get pregnant switching from low-fat dairy foods to the full-fat versions may help you achieve your goal.
