How to Buy Canned Tuna

What to look for on labels to buy the healthiest tuna.

A great meal can start with something as simple as a can opener and a can of light tuna. Light tuna comes primarily from skipjack, a much smaller predatory fish than its cousin albacore or "white" tuna, which is also commonly found in cans. Light tuna provides a healthy dose of vitamin D along with heart-healthy omega-3s. Though it has fewer omega-3s than white tuna does, we go for light tuna because it also has less mercury. Any way you serve it, light tuna is a great catch.

Check the label to find light tuna caught by troll or pole-and-line. It’s the most environmentally sustainable option, according to Monterey Bay Aquarium’s Seafood Watch Program. Or look for the blue Certified Sustainable Seafood label from the Marine Stewardship Council.
