Unagi is much-loved in Japan, and loaded with vitamins and minerals, protein and other key nutrients. “Unagi is also believed to have the highest amount of unsaturated fatty acids than any other sea creature — the omega-3 fatty acid in unagi could help improve blood pressure, lower cholesterol, and help maintain bone health,” says Derocha. “This and vitamin A are believed to reduce wrinkles and keep the skin supple as well.” Look for Japanese unagi, rather than American.

8. OYSTERS

As if you needed an excuse to test whether this shellfish is, in fact, an aphrodisiac! Oysters are not for beginners, but the salty, slimy slurp is a treat that have regulars racing to the raw bar. “Oysters contain a rich amount of zinc, which supports your body’s ability to fight off colds, viruses, and other icky bugs that make you sick,” says Agyeman. Or try cooking them, says Derocha, perhaps in a stew. They are also great for the environment. “The shells are an excellent source of calcium, which when used in the garden can help build strong plant barks as well as balance the soil pH,” she adds.
