This crustacean isn’t just a tasty source of superlean protein, it’s also packed with vitamin B12, which balances mood and fights fatigue. B12 also keeps red blood cells healthy so they can ferry oxygen to our brains, helping us think clearly and stay energized. B12 is only found naturally in animal foods like meat, chicken, and fish, so it might be easy to fall behind on daily needs. Consider crab as an efficient (and delicious) source: One tiny 3-ounce serving dishes up nearly a third of the B12 you need each day for only 71 calories and less than a gram of fat. Buy it canned for a speedy addition to salads, risotto, and pasta or splurge on fresh lump crabmeat for company-worthy crab cakes.
