Study warns pregnant women to avoid canned tuna

HONOLULU (HawaiiNewsNow) - Fish is often thought of as one of the healthiest foods in nature with loads of heart healthy fats and high protein content. But the rising presence of mercury can cause concern, especially for pregnant women.

Most people know that albacore tuna has a higher mercury content compared to "light" canned tuna, and the Food and Drug Administration has said that pregnant women are allowed to eat canned tuna in limited quantities.

Now, a recent study by Consumer Reports says otherwise, warning pregnant women to avoid eating canned tuna entirely.

Consuming too much mercury can result in toxic effects on the nervous system, and the levels in some species of fish have increased to nearly 30% in just the last two decades.

According to Consumer Reports, the problem is that the mercury levels in canned tuna can vary, so you never really know how much mercury you're getting.

The FDA found in their own research, that 20% of the canned tuna tested contained high levels of mercury.

While tuna may not be the best seafood choice if you're expecting, there are safer fish options to eat such as salmon, shrimp, pollock, tilapia, catfish and cod.
