Eating wild-caught fish as part of a heart-healthy diet is a great idea.

However, the fish found in most every American restaurant is far from what you want to be eating.

If you’re concerned about the health of your heart, and having a heart attack, this will be the most important thing you read today.

When patients come to see me concerned about having a heart attack, there are several things I make sure to educate them about:

Heart attack warning signs, so they know when to call 911.

The heart healthiest vitamin they should take each morning.

A simple tip that can reduce their risk of a fatal heart attack by up to 40%!

Plus, certain foods that are supposed to be heart healthy, but are actually the exact opposite.

And those include the 4 fish we’re going to cover today.

Whether you eat these at home, or like to order them when eating out, in my medical opinion you should avoid these as much as possible.



FISH #1 Tilapia

For years, tilapia was promoted by the health and fitness industry as a fantastic fish…

But they couldn’t be more wrong.

In fact, tilapia is one of the WORST fish you can ever eat.

Tilapia contains very few healthy Omega-3 fatty acids…

Which is the #1 reason to eat fish in the first place.

And the concentration of harmful fats in tilapia is almost as high as in lard!

Tilapia is NOT recommended for those who have heart diseases, asthma or arthritis.

But there’s another reason to stay away from tilapia.

Tilapia doesn’t really grow in the wild.

It’s all farmed. And not even in this country!

And only 5% of tilapia is farmed in the United States.

While 95% of tilapia is farmed outside the US in countries which don’t have the same fishing standards as we do.

Which is why most tilapia are farmed in extremely bad conditions.

For example, it’s common for tilapia to spend their entire lives in very small bodies of water.

And since they’re packed so tight, they live in their own filth.

And very often they eat their own feces.

So the farmers throw in huge amounts of antibiotics so they can survive…

Which then trickles down into our system.

So in short, avoid tilapia at all costs!



FISH #2 Mackerel

Mackerel contains mercury which accumulates in the human body.

And it’s very hard to get rid of.

In fact, it takes 12-18 months for mercury to leave our body!

Since the industrial revolution, more and more mercury has been polluted into the oceans.

Which then poisons the fish and enters our body when we eat fish.

And fish like mackerel are especially high in mercury.

It can have a devastating impact on your health.

Make you feel like total garbage.

Cause issues within your muscle tissues making you feel weak.

And for pregnant women, it can lead to developmental issues with their children…

Even slowing down brain development in their offspring.

So mackerel is definitely one to stay away from.



FISH #3 Sea Bass

Sea Bass is another fish which contains a lot of mercury…

But here’s the real problem with sea bass in restaurants.

Sometimes, especially when it’s served as filet…

Instead of sea bass, you get a fish called pangasius.

Which is much cheaper for restaurants to use.

And this is a real problem because most pangasius that we see in our stores is brought from Vietnam…

Specifically, from the Mekong river which is considered one of the most contaminated bodies of water in the world.

Even worse, pangasius contains an elevated level of nitrofurazone, and polyphosphates…

Also known as carcinogens.

This type of fish isn’t recommended for food, at all!

And since it’s so often served instead of sea bass, I highly recommend you stay away from it.

And finally…



FISH #4 Tuna

We all know that tuna contains lots of mercury…

Especially bluefin and blackfin tuna…

But in addition, full grown tuna is almost impossible to find…

Because wild caught tuna is almost extinct.

Almost all tuna comes from farms, where they have poor living conditions…

And the fish are fed with antibiotics and hormones.

When you eat tuna, those hormones and antibiotics end up wreaking havoc inside of your body.

Now, If you absolutely must eat tuna…

Then I highly recommend you choose is yellowfin caught in American waters.

It’s the healthiest kind of tuna.

And because it’s from the USA, it doesn’t have as much in terms of heavy metals.
