Fish fan? Add sushi rolls to the menu tonight! Their savory seaweed wrapping is a well-known aphrodisiac in Asia. The reason: It’s rich in libido-boosting iodine, as well as energizing B-vitamins to keep you in frisky form. Not sure what to buy? Seaweed is currently available in several varieties, including kelp and nori (the usual sushi wrapping), and all will fit the bill. Not a sushi lover? Try some fresh seaweed salad or add some dried seaweed to a bowl of your favorite soup.
