A new study out of Harvard Medical School links high-fat diets with lower sperm counts in men. The more saturated fat men ate, the worse their sperm quality and concentration was. At the other end of the spectrum, eating a lot of omega-3 fatty acids seemed to improve sperm quality.
We all know we’re supposed to eat a healthy diet. This is just one more on the long list of reasons why choosing health food over junk food is good for your body. But if you’re trying to conceive, it might be the one you care most about.
Or it might not. While the findings sound compelling, the study is small and more research is necessary. Most of the men participating in this study were overweight, and none had sperm counts below the “normal” range as defined by the World Health Organization. So it’s not like high fat diets were causing full-on infertility. Just less fertility than you’d get with better food.
The BBC says:
Compared with those eating the least fat, men with the highest fat intake had a 43% lower sperm count and 38% lower sperm concentration (number of sperm per unit volume of semen).
The takeaway here seems to be that you don’t need to give up Big Macs in order to become a Daddy. If you’re interested in eating healthier, though, you might be motivated by the knowledge that you’ll be improving your fertility as well as your fitness.
Will this information affect how you eat? Especially if you’re trying to conceive? Or is it just one more bit of health data in a sea of advice?
