So this video is based on a question someone had about the mercury in tuna fish.

There are certain types of tuna that are good and certain types that are not so good

because they contain three times as much mercury.

Now the problem with mercury is it interferes with certain enzymes involving selenium.

And certain fish have more selenium than others.

And so the mercury that's in the environment, it's in the water that the fish are exposed

to.

It might not affect you too much if there's high amounts of selenium because selenium

can counter this mercury, but you have to realize if there's too much mercury it can

lock up these selenium enzymes rendering them inactive.

And this can create a whole series of mercury toxic symptoms like tremors, headaches, nausea,

insomnia, weak muscles, twitches, mood swings, and there's a lot of other symptoms as well.

And so if you want tuna that's lower in mercury, skip jack is a good source and canned

light tuna.

Now a better option would be to do the canned salmon, sakai, or the pink alaskan salmon,

or even wild-called sardines.

But you want to avoid the tuna that is higher in mercury and that would be the albacore

or the canned white tuna.

Avoid that.

And then avoid ahi tuna, which is yellowfin in big eye because you're going to get three

times as much mercury.

Now if your child is consuming tuna, you want to really bring down the frequency because
