Rich in heart-healthy omega-3s, salmon is a low-calorie protein source that’s likewise low in hydrogenated fat.
Persistent organic toxins (POP)
According to a short article in Diabetology & Metabolic Syndrome, POPs are human-made natural chemicals that take a long period of time to break down. POPs can build up in animal tissue. Fatty fish can include high amounts of POPs.
POPs consist of:
- pesticides
- pharmaceuticals
- industrial chemicals
The exact same short article states that POPs can increase the risk of type 2 diabetes in humans. POPs do this by impacting insulin.
POPs might (properties) also trigger neurotoxicity. Neurotoxicity might increase the threat of Parkinson’s and Alzheimer’s illness.
A current study discovered that wild Atlantic salmon consisted of greater levels of POPs than farmed salmon. This might be due to the fact that their environment is unrestrained and due to contaminants in the oceans.
A study taking a look at farmed Norwegian Atlantic salmon found levels of some POPs and pesticides were decreasing.
It appears that farmed salmon might contain fewer POPs than wild salmon. However, this is dependent on the type of fishmeal that farmed salmon consume.
If choosing farmed salmon, it is helpful to find a reputable, responsible, and sustainably-raised source.
Heavy metals
Heavy metals, such as mercury can produce oxidative tension in the human body. Oxidative stress can trigger damage to the cells, which can, in turn, trigger a range of health conditions.
Other heavy metals in fish include:
- arsenic
- cadmium
- lead
- mercury
One research study found that wild Atlantic salmon consisted of more mercury than farmed Atlantic salmon. All salmon have some level of mercury in their tissues.

A 2003 report from the Environmental Working Group found that seven out of 10 farmed salmon purchased in supermarket were infected with cancer-causing polychlorinated biphenyls (PCBs) at levels that raise health concerns.
Additionally, farmed salmon has been discovered to consist of poisonous chemicals methylmercury and dioxins, and farms have been accused of contaminating the oceans, fostering disease, and spreading sea lice.
Salmon farms have actually also been criticized for other doubtful practices, consisting of the content of the feed, which is typically supplemented with chemicals to give the fish their pink color.
Do the health dangers of farmed salmon surpass the benefits?
Some experts argue that farming practices are improving and ending up being more sustainable, and farmed fish are being fed healthier diets in an effort to improve their dietary profiles. Certain merchants have actually implemented rigorous quality requirements to guarantee they’re sourcing farmed seafood from strictly managed farms.
How should I pick? Firstly, do not panic! Two key considerations: whether the environment the wild salmon comes from is mostly pollution-free, and whether the farmed salmon comes from a respectable farm.
Diet Tips

Unfortunately, it is not constantly possible to discriminate in between wild and farmed salmon by checking out the labels on the bundles.
Judging whether farmed salmon is safe to eat is difficult. The level of impurities in farmed salmon differs from location to location and depends on their diet plan.
Direct exposure to pollutants is still a risk for wild salmon, but research studies may not constantly catch the level of threat.
Generally, wild salmon are nutritionally much better, and sustainably-fished salmon have a lower effect on the environment.
Both wild and farmed salmon are safe to consume and are outstanding sources of nutrients.
