They typically feed on plankton and are close to the bottom of the food chain; many different kinds of predators eat sardines, including humans.
Sardines contain a variety of vital nutrients. Theyâre packed with heart-healthy omega-3 fatty acids, and theyâre a natural source of vitamin D, which is typically obtained from enriched foods. In spite of the benefits, whether canned sardines are good for you depends on one deciding factor: portion control.ven though they're low in total fat, sardines are a good source of omega-3 fatty acids. These fatty acids lower levels of cholesterol and triglycerides in your blood.
