Caviar doesn’t have to be one of those things you have once in a blue moon with a nice bottle of champagne. These little bursting bubbles of fish roe are actually full of vitamins A and D and omega-3 fatty acids, which are great for your skin, among other things. They’re also rich in arginine, which dilates your blood vessels and increases blood flow (this is also why caviar is considered an aphrodisiac). With health benefits in spades, you can have it more regularly, without the guilt.
