Soy (yes, soy) & Salmon
It’s true that soy has been shown in studies to lower sperm counts, but that’s mainly in processed forms such as soy cheese, soy milk, and the unpronounceable forms listed on the labels of your favorite artery-clogging processed foods. This means that eating unprocessed forms of soy, such as edamame and tofu, is perfectly fine in moderation. That’s good news, because an isoflavone in soy called genistein inhibits enzymes in the colon and prostate, raising the amount of vitamin D bioavailability in those tissues, according to Mark Messina, Ph.D., former director of the diet and cancer branch of the National Cancer Institute at the National Institutes of Health and now an adjunct associate professor at Loma Linda University. “The higher vitamin D levels may offer protection against cancer,” says Messina. “There is emerging research suggesting that vitamin D reduces cancer risk, and many people don’t get enough of the vitamin. You do make it in your skin, but most people don’t make enough.” Fish such as salmon and tuna are high in vitamin D, so take a cue from the Asian diet and eat fish with a side of edamame.
