Finding omega-3 fats in fish: Farmed versus wild

Fatty fish are rich in heart-healthy omega-3 fatty acids. But do is farm-raised salmon have a better or worse omega-3 level than wild-caught? While a recent study found that the omega-3 content of farm-raised salmon varies widely, the type of fish you choose probably isn’t as important as following the American Heart Association’s advice to eat two servings of fish a week, letting affordability and availability guide your choices.

Fish oil: friend or foe?

News out of Seattle is sure to fuel confusion about fish oil supplements. A study by scientists at the Fred Hutchinson Cancer Research Center in Seattle linked eating a lot of oily fish or taking potent fish oil supplements to a 43% increased risk for prostate cancer overall, and a 71% increased risk for aggressive prostate cancer. Fish oil loaded with omega-3 fatty acids, which play important roles in health. Deficiencies in them have been linked to a variety of health problems, including cardiovascular disease, some cancers, mood disorders, arthritis, and more. But that doesn’t mean taking high doses translates to better health and disease prevention. Despite this one study, you should still consider eating fish and other seafood as a healthy strategy. Twice a week is a good goal.
