Not All Canned Tuna is Created Equal

Though canned tuna is a good source of protein, omega-3 fatty acids, iodine, iron and B vitamins, too much however, can be problematic for your health.There are some healthier options out there, you just have to know what to look for.

Canned tuna contains methylmercury, a known neurotoxin. If you consume too much of it, mercury can accumulate in your body over time and cause serious symptoms like numbness in your skin, shakes or tremors, difficulty walking, vision problems, memory problems, seizures and damage to the fetal brain when mom eats it during pregnancy or during breast feeding. Additionally, cans can contain BPA, another toxin that can wreak havoc on the body.

If you love tuna like I do, this is kind of a bummer, right? Don’t worry, you don’t have to give up the canned tuna entirely. Here are a few tips on what to look for when buying canned tuna:

  • Read labels (look for BPA free)

  • Opt for light, which has less mercury than white

  • Go for the skipjack variety (albacore varieties have higher mercury levels)

And remember: just with anything in life, moderation is key.
