According to researchers at Harvard University’s School of Public Health, eating red vegetables may increase the production of healthy sperm, the New York Daily News reported.
Researchers found that this antioxidant improves sperm motility, or its ability to swim toward an egg, by 6.5 percent to 8 percent.
Lutein, a carotenoid or antioxidant also found in spinach and lettuce, had a similar effect on sperm motility, researchers said.
The participants with diets rich in lycopene, the chemical that gives tomatoes their red color, had lower levels of abnormally shaped sperm.
The study is published in the journal Fertility and Sterility.
