New research reveals that eating oily fish like wild salmon once or twice a week may increase your lifespan.
STORY AT-A-GLANCE
- Research suggests that eating oily fish once or twice a week may increase your lifespan by more than two years, and reduce your risk of dying from cardiovascular disease by 35%
- Compared to those in the lowest percentiles, those with omega-3 blood levels in the highest 20% were 27% less likely to die of any cause; 40% less likely to die of coronary heart disease, and 48% less likely to die of an arrhythmia
- If you want to maximize health benefits from fish, steer clear of farmed fish, particularly farmed salmon, and even more specifically, genetically engineered farmed salmon, which may end up being approved within the next two years — especially if you’re seeking to improve your omega-3 to omega-6 ratio
- The ratio of omega-3 to omega-6 fat of wild salmon is far superior to farmed. Whereas farmed salmon has a 1-to-1 ratio of omega-3s and omega-6s (due to its “junk food” diet), the ratio for wild sockeye salmon is between 6- and 9-to-1, which is a more ideal ratio
- Avoid Atlantic salmon, as salmon labeled “Atlantic Salmon” typically comes from fish farms. Look for “Alaskan salmon,” and “sockeye salmon,” as Alaskan sockeye is not allowed to be farmed and is therefore bound to be wild
Naturally, there’s still the issue of environmental pollution and contamination, which was not addressed in this study. Do the benefits of eating fish really outweigh the risks of contamination?
In my view, I believe the benefits CAN outweigh the risks, provided you make really wise choices. There are few uncontaminated fish available these days so you need to know what to look for. Needless to say, toxins like mercury and PCB will not do your health any favors.
Higher Blood Levels of Omega-3 Linked to Longer Life Span
The featured study investigated how eating fatty fish affected health. Nearly 2,700 American seniors in their seventies were included in the study. None of them had prevalent coronary heart disease (CHD), stroke, or heart failure at the outset of the study.Rather than rely on food diaries, the researchers measured blood levels of omega-3’s instead. Since none of the participants took omega-3 supplements, their levels were indicative of their omega-3 consumption primarily from fish.
“After controlling for factors like age, sex and lifestyle, the researchers found that, on average, adults with the highest blood levels of omega-3 fatty acids lived 2.2 years longer. In particular, these adults had a 35% lower risk of dying from cardiovascular disease — which is in line with other studies that have tied omega-3’s to cardiovascular benefits.
- 27% less likely to die of any cause
- 40% less likely to die of coronary heart disease, and
- 48% less likely to die of an arrhythmia
In the following video, I interview Randy Hartnell, founder-president of Vital Choice Wild Seafood and Organics, about the differences between wild and farmed salmon. Hartnell spent more than 20 years as a commercial fisherman before forming his company in 2001, which features sustainably harvested wild salmon that are particularly low in heavy metals.
I’m a huge fan of their sockeye salmon, and Vital Choice salmon is about the only type of fish I eat, for reasons I'll discuss below.
Media Tries to Mislead You About Healthful Fish Choices
According to lead author Dr. Dariush Mozaffarian, dean of the Jean Mayer Professor at the Tufts Friedman School of Nutrition Science and Policy, the reason we need omega-3 is because 95% of your cells’ membranes are made of fat. Without fats such as omega-3, your cells cannot function properly. He recommends eating one or two servings of fatty fish per week to optimize your blood levels of omega-3.Interestingly enough, the New York Times[3] gets quite specific about the types of fish recommended: “... 3.5 ounces of farmed salmon, 5 ounces of anchovies or herring, or 15 to 18 ounces of cod or catfish.”
FARMED salmon? I think not ... That is one of your WORST options, for a number of reasons that I will detail below. Cod and catfish also primarily come from aquatic fish farms these days. Unfortunately, fish farming has become big business, and a protected one at that.
Let me put it to you plainly: If you want to maximize health benefits from fish, you want to steer clear of farmed fish, particularly farmed salmon, and even more specifically genetically engineered (GE) farmed salmon. December 21, 2012, the US Food and Drug Administration took a giant step closer toward the final approval of the first genetically engineered (GE) food animal — a salmon designed to grow abnormally fast,[4] and to an unnaturally large size.
Today, if you get Atlantic salmon, it is all farmed, as commercial fishing for wild Atlantic salmon is banned in the U.S. under the Endangered Species Act.[5] Not only that, the FDA has approved the farming and sale of GE Atlantic salmon across the U.S. Most recently, a land-based salmon farm is going up in Pioneer, Ohio, in a 479,000 square-foot building, with the first harvest targeted for 2025.[6]
“AquAdvantage Salmon has been genetically engineered to reach a growth marker important to the aquaculture industry more rapidly than its non-GE Atlantic salmon counterpart.
How to Identify Wild Salmon From Farm-Raised
Unfortunately, salmon are often mislabeled (and when they are, as of January 1, 2022,[7] they’re labeled as “bioengineered,” a term that the USDA thought up, complete with a green, white and yellow label). Additionally, some studies have shown that as much as 70% to 80% of the fish marked “wild” are actually farmed. This includes restaurants, where 90% to 95% of salmon are farmed, yet may be mis-listed on the menu as “wild.”So, how can you tell whether a salmon is wild or farm-raised? The flesh of wild sockeye salmon is bright red, courtesy of its natural astaxanthin content. It’s also very lean, so the fat marks, those white stripes you see in the meat, are very thin. If the fish is pale pink with wide fat marks, the salmon is farmed. That’s why you should avoid Atlantic salmon which, as I said, comes only from fish farms.
Why Farmed Salmon Is an Inferior Choice
As the first video discusses, there are three major differences between wild-caught and farmed salmon, and once you realize how different the fish are, based on how they were raised, you'll see why opting for the cheaper alternative isn’t the wisest choice — especially if you’re seeking to improve your omega-3 to omega-6 ratio:- Nutritional content — Wild salmon swim around in the wild, eating what nature programmed them to eat. Therefore, their nutritional profile is more complete, with micronutrients, fats, minerals, vitamins and antioxidants like astaxanthin (which gives salmon its pink, or in the case of sockeye, red-colored, flesh.)
- Fish Health — Wild salmon return to their native spawning grounds each year, without you having to do anything, while farmed salmon are kept in pens. Naturally, fish swimming in the wild get more exercise, and this alone makes wild fish healthier than their incarcerated counterparts.
- Environment — Nearly 99% of farmed salmon are raised in net pens in the open ocean. All the excess food that is dropped in ends up going out in the environment — the genetically engineered ingredients, the pesticides, the antibiotics and chemical additives. Anything the fish do not consume, along with all their now unnatural waste products, ends up contaminating the environment.
Lethal Salmon Virus Found in Installed Salmon Farms
In 2011, according to whistleblower Rick Routledge, professor and fisheries statistician at Simon Fraser University in Canada, wild river inlet sockeye were found to be infected with infectious salmon anemia virus (ISA), also known as salmon influenza.[12] This highly lethal and much-feared virus is directly attributed to farmed salmon, and has proliferated in every region across the globe where Atlantic salmon farms have been installed.At least 11 species of fish in the British Columbia’s Fraser River were also been found to be infected with ISA, yet the Canadian food inspection agency has aggressively refuted the findings. In fact, everyone who spoke up about these salmon viruses, which can be traced back to salmon farms, was shut down in some way or another.
By muzzling scientists looking into this problem, the Canadian government was allowing potentially contaminated farm-raised salmon to be sold, exported, and consumed, which is yet another reason to avoid farmed salmon.
- ISA has only appeared where salmon are raised in aquaculture and has spread worldwide since first being reported in Norway in 1984.
- ISA can infect herring, as well as, salmon. ISA was first reported in Eastern Canada in 1996 and continues to cause problems there.
- In 2007, ISA began in a nonlethal form in Chile and became a virulent epidemic killing 70 per cent of the farm salmon. Chile does not have wild salmon.
- In January 2009, a group of Canadian scientists, including David Suzuki, signed a letter warning the Canadian Fisheries Minister of the risks of introducing ISA into B.C.
“Currently, PRV-1 is running rampant in farms where Atlantic salmon are raised. The authors found that more than 97% of fish in all Atlantic salmon farms had the virus by the time they were 18 months into the aquacultural production cycle. From those farms, the authors’ findings suggest, PRV-1 is continually spreading to wild Pacific salmon …
The Best and Worst Fish in Terms of Environmental Toxins
Interestingly enough, and fortunately for us, the types of fish that tend to suffer the least amount of toxic contamination also happen to be some of the best sources of fat and antioxidants. So, by choosing wisely, the benefits of a diet high in fish can still outweigh the risks.Most major waterways in the world are contaminated with mercury, heavy metals and chemicals like dioxins, PCBs and other agricultural chemicals that wind up in the environment.
However, the risk of authentic wild-caught Alaskan sockeye salmon accumulating high amounts of mercury and other toxins is reduced because of its short life cycle, which is only about three years. Additionally, bioaccumulation of toxins is also reduced by the fact that it doesn’t feed on other, already contaminated, fish.
If you still want to take precautions, you can do what I do: Whenever I eat fish, I eat it with chlorella tablets. The chlorella is a potent mercury binder and if taken with fish will help bind the mercury before your body can absorb it, so it can be safely excreted in your stool.

- Anchovies
- Herring
“… people averaging about 14 grams of tuna each day had a 20-percent higher risk for malignant melanoma than those averaging just 0.3 grams per day. Similarly, those eating 17.8 grams of nonfried fish per day had an 18-percent higher risk of developing melanoma and a 25-percent higher risk for stage 0 melanoma.” Study authors added:
- Tuna (tuna steaks, sushi, and canned)
- Sea bass and largemouth bass
- Marlin
- Halibut
- Pike
- Walleye
- Shark
- Sword fish
- White croaker
Enjoy Your Fish, but Choose Wisely!
Fish has always been the best source for the animal-based omega-3 fats EPA and DHA, but as levels of pollution have increased, this treasure of a food has become less and less viable as a primary source of healthful fats. However, there are still exceptions, and the key is to understand which types of fish are the least contaminated.I strongly recommend buying wild fish, and Wild Alaskan salmon is in my opinion one of the absolute best, both in terms of nutrition and potential contamination.
Remember, fish farms are the aquatic version of a confined animal feeding operation (CAFO), and just like land-based cattle and chicken farms, fish farms breed disease due to crowding too many fish together in a small space.
They also produce toxic waste and fish of inferior quality. These fish are further contaminated by drugs and genetically engineered corn and soy meal feed, and in the case of salmon, synthetic astaxanthin, which is made from petrochemicals that are not approved for human consumption.
