There's some heavy metal, but much lower than other fish.

And you have to be careful because it concentrates up the food chain.

So, you know, fish that eat other fish, that eat other fish, that eat other fish are the ones that are highest in mercury.

Shark, swordfish, tuna.

If you're in a home, there's plumbing, paint, homes built before lead regulations, cigarette smoke, one of the highest sources of toxins in general, but also can have chemicals and metals in them.

So be careful.

These metals can cause havoc.

I experienced it personally because I had mercury poisoning.

They affect your nervous system.

They can cause brain fog, fatigue.

I developed chronic fatigue syndrome from it, cognitive impairment, sleep issues.

I developed muscular damage, neurological damage.

It was bad.

In children, it can have a huge effect because it affects developmental learning and development of the brain.

So a lot of kids have problems.

One in six kids today have some neurodevelopmental disorder.

It's very concerning.

And heavy metals play a role.

The next thing you want to do is filter your drinking water.

I have a reverse osmosis filter at home.
