13 Trendy Foods We Waste Too Much Money On

Tuna is called “sea dumpster.”

Tuna also often appears on the lists of healthy foods. Just like any kind of fish, it contains fatty acids and phosphorus. But, aside from these healthy elements, it often contains something you don’t need at all — mercury. This is the result of the dirty environment that tuna are very susceptible to.

So, if you want to eat some fish, there is no need to pay extra money for tuna. You can buy regular mackerel instead. It contains just as much phosphorus but doesn’t absorb mercury as fast as tuna does.
