but any salmon is better than junk food.
Here's interesting research about the high level of toxic metals found in farmed salmon compared to wild salmon. It's unfortunate that the headlines are ablaze with this news, since eating salmon is such a healthy way to get Omega-3 fatty acids into your diet, but it's also worth pointing out that salmon raised in captivity are not the same as salmon raised in wild.
Whether this news will cause people to avoid eating salmon remains to be seen, but hopefully, the public will take this in context and realize that the health benefits of eating salmon are very great in deed, and that the toxicity of junk foods is very likely much higher than that of even farm raised salmon.
Of course there are also defenses you can use against the heavy metals found in salmon, shrimp and swordfish. A variety of nutritional supplements are available that absorb these heavy metals before they reach your digestive tract, protecting your body from suffering the destructive effects of toxins like mercury, lead, and arsenic.
