#22 Canned Sardines
Before you start questioning this… yes, canned goods contain processed food, but according to the Food and Drug Administration, canned sardines are a healthy alternative to their fresh counterparts.
Also, sardines generally contain a lot less mercury than most other types of fish, and they provide just as many omega-3 fatty acids as pink salmon. And health buffs already know that omega-3 fatty acids lower blood pressure, slow the development of plaque in the arteries, reduce the risk of heart ailments, help maintain normal heart rhythm, minimize triglycerides, and prevent strokes. Flex your canned sardines, people!
