2. Fatty Fish

Few foods have built as strong a reputation with cardiologists as fatty fish like salmon, mackerel, and sardines. They’re packed with omega-3 fatty acids, which help lower triglycerides, ease blood pressure slightly, and reduce the odds of dangerous heart rhythm problems. Some research even suggests omega-3s can slow the buildup of plaque inside your artery walls. Aim for two servings a week — grilled, baked, or pan-seared all count. It’s one of the easiest swaps you can make for a heart that works less hard.
