Canned tuna has long been considered a health food.
It’s packed full of protein and low in fat, making it a great option for lunch or dinner.
But did you know that canned tuna isn’t always safe to eat?
In fact, some brands contain high levels of mercury, a toxic metal that can cause serious damage to your brain and nervous system.
Mercury is a naturally occurring element found in rocks and soil.
It’s also present in the atmosphere, where it becomes part of rainwater and snowmelt.
Mercury enters our bodies through fish consumption, air pollution, dental fillings, and other sources.
While it’s true that canned tuna contains less mercury than fresh tuna, it’s still important to limit your intake.
The Environmental Working Group EWG recommends limiting your tuna intake to 12 ounces per week.
If you want to get even healthier, try switching to tuna packed in water instead of oil
