Fish Oil Capsules Are as Good as Fish

The average American diet is seriously deficient in these essential omega 3's. Except for certain types of fish, there are very few sources of these vitally important fats. Unfortunately, what these studies don’t take into consideration is the sad fact that so much of our fish supply is grossly contaminated, and therefore completely counteracts any inherent benefits of the fish.

It would have been quite interesting to see these women’s mercury levels in addition to their omega-3 serum levels. If heavy metal contamination had been taken into account, the final conclusion would most likely have been that omega-3 supplements are in fact far superior to fish – especially tuna!

Are You Loading Up on Mercury or Omega-3?

The world’s oceans are so polluted with industrial waste that most commercially available fish have become significantly polluted  with many toxins – especially mercury -- throughout all the fat and tissues of their bodies. This shouldn’t come as a surprise, considering the fact that some 40 tons of mercury are released in the United States alone, every year, due to burning coal to generate electricity.

The most common contaminants found in fish include:

• Mercury
• PCBs
• Radioactive substances like strontium
• Toxic metals such as cadmium, lead, chromium and arsenic

Smaller fish, such as herring, sardines, and anchovies fare better than larger fish since they don’t have time to accumulate much mercury in their tissues. The highest concentrations are found in the large carnivorous fish of the ocean.

These are some of the ones you should definitely avoid, especially if you are pregnant, or trying to become pregnant: 

GotMercury.org is a good website if you’re curious to see just how high your intake of mercury might be. Not only do they have a handy mercury calculator, but they also perform independent testing on various sources of fish.

For example, if you’re a sushi lover and happen to live in the Chicago area like me, you may want to take a look at their Mercury Contamination in Chicago Tuna Sushi Report. After testing mercury concentrations in tuna sushi samples from ten high-rated Chicago sushi restaurants, the results were less than encouraging:

• The mean concentration of all 20 samples was 0.445 ppm (parts per million) total mercury – very close to the 0.5 legal limit in Canada and the EU
• 70 percent exceeded the Illinois Environmental Protection agency’s (IEPA) special advisory threshold for methylmercury. At that level, women of childbearing age and children are advised to eat no more than one serving per month
• 14 percent had a concentration higher than 0.730 ppm – a level that no women or children should ever consume
• 10 percent of the tuna samples were unsafe for all consumers, because they contained mercury levels above 1.0 ppm, which is the legal action limit for fish sold in the U.S.

Also be especially cautious of canned tuna if you’re interested in keeping yourself and your children safe from mercury contamination.

Most canned tuna is labeled either “albacore” or “chunk light.” According to FDA data, albacore (white) tuna contains three times more mercury than chunk light (0.353 ppm vs. 0.118 ppm). However, independent testing by the Mercury Policy Project found that the average mercury concentration in albacore canned tuna actually exceeded 0.5 ppm.

It’s often difficult to make practical use of these numbers, so to give you a better idea of the level of danger, consider this:

• A 22 pound toddler who eats just 2 ounces of tuna per week with a 0.5 ppm mercury concentration would exceed the EPA’s “virtual safe limit” by 400 percent
• A 132 pound woman who eats 12 ounces of tuna per week with a 0.5 ppm mercury concentration would also exceed the EPA’s limit by 400 percent
• An 88 pound child who eats 6 ounces of tuna per week with a 0.5 ppm mercury concentration would exceed the limit by 300 percent

Is Farm-Raised Fish a Healthier Choice?

Unfortunately, the answer is no. In farmed fish, you not only have the problem of mercury, but also higher PCBs, another poisonous industrial byproduct. Residues in farm-raised fish can be as much as 9 million times the amount found in the water.

If you eat fish in a restaurant, it most likely came from a fish farm. Almost half of the salmon, 40 percent of the mollusks, and 65 percent of the freshwater fish consumed today are raised in fish farms. What you may not know it that in order to be profitable, fish farms must raise large quantities of fish in confined areas, and the overcrowding leads to disease and injuries to the fish. The fish are therefore given antibiotics and chemicals for the parasites like sea lice, skin and gill infections and other diseases that commonly affect them.

Making matters worse, these fish are also given drugs and hormones, and sometimes are genetically modified, to accelerate growth and change reproductive behaviors. Farmed salmon are also given the chemicals canthaxanthin and astaxanthin to turn their flesh pink. Wild salmon eat a diet of shrimp and krill, which contain natural chemicals that make the salmon pink. Farm-raised salmon do not eat a natural diet, so their flesh would be gray if they were not given these additives.

Choosing the Best Omega-3 Supplement 

In a perfect world, fish would be a near-perfect food -- high in protein and full of essential nutrients and fats. But, as you now know, our world is not perfect, and nature’s bounty has been in large part destroyed. Therefore, I do not recommend eating any fish -- unless you have lab results in your hand that can attest to its purity. One such source is the Vital Choice Wild Alaskan salmon, which I have had tested on numerous occasions and have found to be mercury free.  

Your safest bet, however, is to take a high-quality omega-3 supplement on a regular basis. I used to highly recommend taking fish oil or cod liver oil, and I still do in some cases, but they do have drawbacks. Unfortunately, fish oil is weak in antioxidant content. Not only that, but as you increase your intake of omega-3 fats by consuming fish oil, you actually increase your need for even more antioxidant protection.

Why?

Well, fish oil is highly perishable. Antioxidants are necessary to ensure that the fish oil doesn't oxidize and become rancid inside your body (oxidation leads to the formation of unhealthy free radicals).

Because of this, I now recommend getting your omega-3 fats from Antarctic krill oil. It is superior to fish oil because it contains phospholipids, antioxidants – more than 47 times the levels found in fish oil! -- and omega-3 bonded together in a way that keeps them safe from oxidation, and makes them easily absorbed in your body. So with krill oil, you can ensure that you’re getting these incredibly healthy fats (EPA and DHA) without having to worry about oxidation issues.

Additionally, your risk of getting any mercury contamination is extremely small, as krill are so small they do not have the chance to accumulate toxins before being harvested.
