Why You Should Eat Fish

People have been eating fish since the dawn of man. It’s been a staple for humankind in every area where fish can swim and has without a doubt been one of the foods that have kept humans alive, but in many more ways than offering mere sustenance. It’s a lean protein, with vitamins, minerals, fatty acids and numerous compounds that can stave off high blood pressure, macular degeneration, depression, osteoporosis and diabetes.

Another new study in the journal Circulation reveals that people who eat two or more servings of oily fish per week had a “significantly lower risk of heart attack and stroke,” even in individuals who don’t make “eating healthy” a priority. The study authors wrote:

“We conclude that one to two seafood meals per week be included to reduce the risk of congestive heart failure, coronary heart disease, ischemic stroke, and sudden cardiac death, especially when seafood replaces the intake of less healthy foods.”

One of the most glowing reviews of fish as a healthy food was in light, again, of the high levels of omega-3s, with a notation that they’re one reason the Mediterranean diet has been all the rage over recent years. Omega-3s enter your cell membranes, which is important for cell signaling and essential for an optimally functioning heart. Forbes noted a number of other perks:

“Research has focused largely on the anti-inflammatory influence of omega-3s, which counters the hardening and narrowing of arteries that characterizes heart disease. Diets higher in omega-3s are also linked to lower triglyceride levels and fewer fatty deposits that clog arteries …

But don’t think a Friday night plate of fried catfish and slaw will fill the need. Eating fried seafood doesn’t provide the same benefits, and likely contributes to the very problem eating non-fried fish helps improve. The results of one study suggested that people who ate fried fish at least once a week were nearly 50 percent more likely to develop heart failure than those who rarely ate fried seafood.”

So should you eat fish? Again, pregnant moms and young children — and really, everyone — should steer clear of high-mercury seafood, but if you choose the healthiest options, the benefits are worth the risk for most people.

As a general rule, your best choices are small, cold-water, fatty fish, which are an ideal source of omega-3s with a low risk of contamination. The healthiest fish I suggest you consider eating more often include anchovies, sardines, mackerel, herring and wild-caught Alaskan salmon — step away from farmed varieties, both for your health and for the environment.

Toxic Threats to Farmed Fish Food

Science reported that a worldwide assessment of the threat to the salmon market as a whole can be answered by the 13 persistent organic pollutants, including PCBs (polychlorinated biphenyls), known as one of the most toxic and environmentally persistent chemicals ever created.

The Environmental Protection Agency (EPA) notes that PCBs (and there are dozens of trade names for them) don’t break down, can remain for long periods cycling between air, water and soil, travel long distances and can be taken up into the bodies of small organisms and fish.

“Studies in humans support evidence for potential carcinogenic and noncarcinogenic effects of PCBs,” it notes, but the list of potential health problems for humans and animals is frankly staggering. Sure, industries are now being regulated to more stringent laws, but once it’s out there, trying to take it back is no longer possible. The EPA site details a list of life-altering and hair-raising consequences PCBs can cause or impact:

Cancer	Immune system
Reproductive system	Nervous system
Endocrine system	Neurological effects

Keep in mind that PCBs are only one of many pollutants associated with farmed fish. One of the most treacherous is ethoxyquin, a chemical developed by Monsanto in the 1950s as a synthetic tire chemical. Ethoxyquin is found only in farmed salmon — not in wild.

It’s used as a rubber stabilizer, pesticide, preservative and antioxidant all in one, and is a suspected carcinogen that “caused chromosomal aberrations, holes and fractures in chromosomes” of human cells and “was chemically toxic, destroyed chromosomes and DNA,” according to a Norwegian newspaper review.

Because it prevents fat oxidation, it’s used in some animal feeds, including fish food. According to Nutraceutical Business Review, the European Food Safety Authority’s description of the chemical was pretty clear: Ethoxyquin is “considered to be toxic to aquatic organisms based on the acute toxicity data provided for fish, daphnia and algae.”
