Not only do sardines taste great — they really do! — they’re very healthy, too. These little fish are packed with protein, calcium, vitamins B12 and D, and a nutrient called Omega-3 fatty acids, which is good for your heart and your brain. Sardines are also “sustainable” — which means that they’re quick to grow and reproduce, so we won’t run out of them or make them become extinct by eating them. There are lots of varieties to choose from: Some are plain and packed in water or olive oil, some are smoked, some are spicy, and some come packed in different kinds of sauce, like tomato or mustard. Try a few different kinds to find out which one you like best.
