While we’re on the topic of heart-healthy fish, why not tuck into some mackerel? Sure, it may taste a little on the strong side, but mackerel has even higher percentages of omega-3s than wild salmon! You’re even better off having mackerel once a week than popping fish oil pills every day. The vitamins and minerals found in mackerel help your body to more effectively absorb and utilize the fatty acids. The best news is that mackerel is virtually never farmed, so you know you’re getting wild-caught fish every time.
