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.
CALORIES, FAT AND CHOLESTEROL According to the Department of Agriculture, one can of sardines packed in oil contains 191 calories and 11 g of fat. Fortunately, most of this fat is polyunsaturated or monounsaturated rather than saturated. Sardines are one of the best sources of certain heart-healthy omega-3 fatty acids.
