Can Foods Make You Fertile?

I was recently interviewed for an article by The Daily Beast, entitled “Can Foods Make You Infertile?” The author wanted to substantiate some research claims about foods that were good and bad for your fertility. It is an interesting piece. I still take issue with the study on whole milk and ice cream being good for your fertility, but they were not looking for refuting evidence; only substantiating evidence. Milk is not good for your fertility, but fat is. Milk fat, butter fat, Omega-3s, coconut oil, flaxseed oil… I still advise avoiding cow dairy products, and including plenty of non-trans fat. Other than that, here is the list from the Daily Beast:

1. Men who drink at least a quart of cola daily have sperm counts almost 30 percent lower than men who drink no cola.

2. Women who eat lots of low-fat dairy products face an 85 percent higher risk of ovulatory infertility than women who consume little or no low-fat dairy products.

3. Men who eat large quantities of soy-based foods produce 32 percent less sperm per milliliter than men who consume no soy-based foods.

4. Women who consume at least one daily serving of whole milk are more than 50 percent less likely to experience ovulatory infertility than are women who consume less than one serving of whole milk per week.

5. Men who are exposed to large quantities of bisphenol-A (BPA), a chemical used in the manufacture of canned foods, have sperm counts about 23 percent lower than men with no BPA exposure.

6. Vegan women are only one-fifth as likely to have twins as are vegetarian and omnivorous women.

7. Men with high concentrations of trans-fatty acids in their semen have 96 percent fewer sperm than men with low concentrations of trans-fatty acids in their semen.

8. Women who consume at least one alcoholic beverage per day have a nearly 50 percent greater risk of ovulatory infertility than women who drink no alcohol.

9. Women who are exposed to large quantities of perfluorooctanoic acid (PFOA), a synthetic chemical used in the linings of microwave-popcorn bags, face an infertility risk ranging from 70 percent to 134 percent higher than that of women with the least amount of PFOA exposure.

10. Men who eat a traditional Dutch diet have sperm counts nearly twice as high as do men who eat a fish-and-produce-based diet.

11. Women who eat large quantities of omega-3 fatty acids are 22 percent less likely to be diagnosed with endometriosis—a common cause of infertility—than women who eat little or no omega-3s.

12. Women who consume large quantities of non-heme iron—the kind found in lentils, spinach, and supplements—have a 40 percent lower risk of ovulatory infertility than women who consume little or no non-heme iron.

13. Women who consume at least 5 percent of their daily calories in the form of vegetable protein rather than meat protein have a 50 percent lower risk of ovulatory infertility than women who consume only meat protein.

14. The sperm of men who consume very low quantities of antioxidants is only two thirds as motile as the sperm of men who consume high quantities of antioxidants.

15. Men whose mothers ate beef at least seven times a week while pregnant with them are three times as likely to have low sperm counts as men whose mothers ate less beef while pregnant.
