What does fish oil do for the body?
Fish oil is often recommended for a healthy diet because it contains the omega-3 fatty acids, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), that are said to have many health benefits. Let’s see what the recent studies reveal...
What good does fish oil do for the body?
According to Medline Plus
a service of the US National Library of Medicine, the intake of recommended amounts of DHA and EPA in the form of dietary fish or fish oil supplements:
- lowers blood triglyceride levels
- reduces the risk of heart attack
- reduces the risk of dangerous abnormal heart rhythms
- reduces the risk of strokes
- slows the buildup of atherosclerotic plaques
- lowers blood pressure slightly
An omega 3 fish oil supplement may also help with Alzheimer's disease and dementia, depression, heart disease, cancer, arthritis, diabetes, hyperactivity, ADHD.
What does fish oil do for your skin?
A recent study by dermatology researchers at Hope Hospital in Manchester, England, revealed that oily fish in our diets helps prevent skin cancer because essential fatty acids protect the skin against the DNA damage that can cause skin cancer. The study was published in an article called, “Fish oil to boost skin health,” published by the University of Manchester on January 20, 2009. The study was published in Insciences, a non-profit organization based in Switzerland. See: New Studies Reveal Oily Fish Helps Fight Skin Cancer

Although skin benefits are proposed for alpha-linolenic acid, scientific evidence is less compelling, and beneficial effects may be less pronounced. Multiple studies have been conducted in humans, with mixed results. Max-EPA fish oil supplement has been used in studies and has shown mild to moderate improvement in people's psoriasis. But most studies of EPA for eczema and psoriasis do not provide enough reliable evidence to form a clear conclusion.
Can fish oil harm your body and how to prevent the side effects?
Such fatty predatory fish like mackerel, lake trout, flounder, albacore tuna and salmon may be high in omega-3 fatty acids, but due to their position at the top of the food chain, these species can accumulate toxic substances.
Try to limit your consumption of fish species that are at the top of the food chain.
Instead of consuming fish every day, taking a fish oil supplement on a regular basis appears to be a safer choice nowadays.
A report by ConsumerLab.com
which conducts independent tests of supplements, examined 41 common
fish oil products and found none contaminated with mercury or PCBs.
report, by researchers at Harvard Medical School and at Massachusetts
General Hospital, studied five popular brands of fish oil, including
Nordic Ultimate, Kirkland and CVS. They found that the brands had
“negligible amounts of mercury, suggesting either that mercury is
removed during the manufacturing of purified fish oil or that the fish
sources used in these commercial preparations are relatively
mercury-free.” See: The Claim: Fish Oil Supplements Can Contain Mercury
take care when choosing and don't be guided simply by price as things
like dosage, purity and freshness all play their part.
Fish oil is primarily EPA and DHA, both of which are extremely
unsaturated. The greater the degree of unsaturation, the greater the
propensity to go rancid. When these oils go rancid, they convert to
harmful oxidized fats called lipid peroxides which can damage fatty
cellular membranes. How to avoid fish oil to go rancid?
your capsules in glass bottles because they are impervious to air, and
put the glass bottle in the refrigerator. The cold will markedly slow
down the oxidation process even if a little air gets in the bottle.
High doses may have harmful effects, such as an increased risk of bleeding. "Intake of 3 grams per day or greater of omega-3 fatty acids may increase the risk of bleeding, although there is little evidence of significant bleeding risk at lower doses. Very large intakes of fish oil/omega-3 fatty acids may increase the risk of hemorrhagic (bleeding) stroke." (NIH Medline Plus. "MedlinePlus Herbs and Supplements: Omega-3 fatty acids, fish oil, alpha-linolenic acid"
Omega 3 is an essential fatty acid, which means is cannot be manufactured by our own body and therefore must be obtained through our diet alone. Most people's diet's contain an insufficient amount of omega 3 and a very high amount of the omega 6 fatty acid. The ideal ratio of the two is something near 2:1. But in reality for the average person, it's more like 20:1 or even more. Most people lack omega 3, which is why a fish oil supplement is usually beneficial. However, it is best to ask your practitioner for safe dosage.
