Which has the most mercury? -Carol H.
Here are your seafood answers, Carol:
1) Tuna packed in oil contains way more fat and calories, otherwise the nutrition is the same. The oils most used with canned tuna are sunflower oil or olive oil, and both contain healthy unsaturated fats.
2) A 10 year-old study states “There were no significant differences in mercury levels in tuna packed in oil compared to water,” and found that draining the fluid didn’t affect mercury levels. According to the Environmental Protection Agency, solid white albacore tuna has nearly three times the mercury content of canned light.
The official EPA advisory recommends that adults eat up to two 6 oz servings of low mercury fish/shellfish per week. The fish with the highest mercury to avoid are swordfish, king mackerel, tilefish and shark.
