Watermelon rind as a sex boosterElvira Koneva/Shutterstock
Watermelon rind has nutritional benefits too: Not only does it contain vitamins C and B6 (skin, immunity, and nervous system boosters), but it could also sweeten your sex life. In a 2008 study, Texas A&M University researchers found that watermelon rind has high concentrations of the compound citrulline, which your body converts into an amino acid that helps improve circulation and relax blood vessels—even down there. To salvage rinds, blend them into a fruit smoothie, or try sautéing and adding to a stir-fry. They’ll contribute a zucchini-like texture and a slightly sweet flavor. Here are some more foods you may not know are aphrodisiacs.

About 40 million tons of banana peel are disposed of or go unused each year worldwide, according to a 2013 study. Use yours to polish leather (rub it against the outer side, then buff with a soft cloth) or to heal wounds (rub the pulp side on bruises and scrapes to deliver potassium) or to fertilize plants (soak peels in a jar of water—then mix five parts tap water to one part banana-water). You can also eat them! A 2011 article in Applied Biochemistry and Biotechnology found that banana peels contain many healthy antioxidants like carotenoids and polyphenols (thought to prevent diabetes, heart disease, and cancer). Wash well, then blend into a fruit smoothie. Alternately, boil chopped peels for 10 minutes and add to your favorite dish. In Indian dry vegetable curry, for example, chopped banana peels boiled with turmeric powder and salt are mixed with ingredients like mustard seeds, green chillies, and cabbage for a healthy meal. You shouldn’t throw banana strings away, either!
