Sardines are an important part of the food chain. Jupiterimages/Photos.com/Getty Images. Sardines live in large schools that may contain thousands of fish. They typically feed on plankton and are close to the bottom of the food chain; many different kinds of predators eat sardines, including humans.
If you get your hands on some fresh sardines, they feature in fabulous recipes originating from all over the Mediterranean basin. But sardines are so simple and basic, you really donât need a recipe to get the best out of them.. They arenât bad for you. Sardines are low on the oceanic food chain, and therefore contain low amounts of mercury, PCBs and the other toxins that accumulate in longer-living marine predators such as salmon and tuna. This makes them a particularly good choice for children and pregnant women.
