There Is Panic Concerning Mercury Poisoning In Our Fish. Tuna Is The Most Common Fish Mentioned, But Other Fish Have It Too.

Does Your Fish Have Mercury Poisoning?

Will It Hurt Your Weight Loss Program Or Kill You?

 

 

Mercury poisoning seems to be in everything from the sea.

Will it hurt us?

• • The fish most likely to be contaminated with unsafe levels of mercury are those highest up on the food chain, including shark, king mackerel, tilefish, and swordfish.
  • The fish with the least mercury are salmon, trout, catfish, haddock, flounder, crab, or shrimp.
  • Most health organizations still recommend including high-fat fish such as salmon, herring, trout, sardines, or mackerel at least twice per week to provide healthy omega 3 essential fatty acids (EFA’s).
  • If you don’t eat fish, a pure fish oil supplement is a good idea.
  • Use flaxseed oil, which is the richest vegetable-based source of essential fatty acids.
  • You would have to stop eating (and breathing!) to avoid exposure to every possible toxin.
  • The Center for Science in the Public Interest (CSPI), recommends the equivalent of only 1 can of white (albacore) tuna per week or 2 cans of light tuna. However, they added that men, older children, or women beyond childbearing age could probably safely consume 2 to 3 times these amounts. (This would increase their recommended limit to just under a can a day).

 

Mercury Poisoning, Tuna, And Mercury
Are You Being Poisoned By The “Healthy” Fish You’re Eating?

By Tom Venuto, NSCA-CPT, CSCS

QUESTION: Hi Tom: I love albacore tuna or salmon.

Do you have any concerns about the levels of mercury now being found in tuna and in larger fish?

I still eat them. I’d have to quit eating to avoid all the things wrong with food.

I’ve never been too environmentally minded, but I found myself perturbed that the fish are becoming toxic, little by little.

My vegetarian daughter is our family environmentalist, and I’m on her side on this one.

Recently there was an article in our paper suggesting that the breast milk of a nursing mother, could now be considered toxic in a high percentage of cases.

If true, it’s a sad indictment of our society.

 

ANSWER: According to the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA), the fish most likely to be contaminated with unsafe levels of mercury are those highest up on the food chain, including shark, king mackerel, tilefish, and swordfish.

These larger, longer-lived predatory fish feed on the smaller fish and retain in their bodies the contaminants that were in the small fish.

The FDA released a mercury advisory warning in 1994, which advised the public that these fish were safe as part of a balanced diet if eaten no more than once per week. In 2001, the FDA upgraded its advisory, recommending that pregnant women, nursing women, or women of childbearing age who may become pregnant, avoid the high-risk fish completely because mercury can harm the nervous system of a developing unborn baby.

According to the FDA, the fish with the least mercury are salmon, trout, catfish, haddock, flounder, crab, or shrimp. And what about tuna fish – that classic bodybuilding and fitness staple food?

The FDA says that certain species of large tuna, usually sold as fresh tuna, tuna steaks, or sushi, can have mercury levels above the FDA’s danger level of 1 part per million.

The smaller tuna species such as albacore and skipjack, have much lower levels of mercury (that’s why canned tuna is less likely to be contaminated with mercury than fresh tuna).

In a recent report on tuna and mercury published by the Center for Science in the Public Interest (CSPI), they recommend the equivalent of only 1 can of white (albacore) tuna per week or 2 cans of light tuna.

However, they added that men, older children, or women beyond childbearing age could probably safely consume 2 to 3 times these amounts. (This would increase their recommended limit to just under a can a day).

I know a lot of bodybuilders who eat can after can of tuna every day… some live on it as their prime protein source. In the 60’s and 70’s some of the bodybuilders of that era were famous (or infamous) for their Spartan “tuna and water” diets for getting ripped very quickly.

Today, unfortunately, this practice appears unwise.

I used to be one of those 2-3 cans of tuna a day guys too.

Even though it was bland, it was a fast and easy way to get lean protein for a bodybuilding diet.

Today I eat a much wider variety of lean proteins, including a wide variety of fish, including salmon or trout two or three times per week, and I recommend the same to my clients.

Most health organizations still recommend including high-fat fish such as salmon, herring, trout, sardines, or mackerel at least twice per week to provide healthy omega-3 essential fatty acids (EFA’s).

In light of the Mercury scare, many people are turning to fish oil pills to get their EFA’s.

Aside from providing an uncontaminated source of EFA’s (check the purity standards of the manufacturers), the list of health benefits of fish oils seems to keep growing and growing.

I prefer to eat fish a few times a week rather than take handfuls of pills.

I spare no expense to get wild (not farmed) Alaskan salmon. This gives me quality calories, lean protein and omega 3’s at the same time. It tastes good and is more economical, besides.

But if you don’t eat fish, a pure fish oil supplement is a good idea. You can also use flaxseed oil, which is the richest vegetable-based source of essential fatty acids, although the conversion of ALA must take place in the body to EPA and DHA, the omega-3 fats found in marine oils.

In summary, it would be wise to pay attention to the FDA and EPA warnings and guidelines, but moderation in all things is good advice in this situation, rather than total paranoia.

When I’m dining out, I’ll occasionally have swordfish, fresh tuna steak, or sushi and I don’t give any thought to whether it’s contaminated – I just enjoy it.

As you said, you would have to stop eating (and breathing!) to totally avoid exposure to every possible toxin… and the people who live in fear of disease are usually the ones who get it.
