As farmed salmon becomes a regular feature in diets, it is important to understand its nutritional benefits. Salmon is still an excellent source of omega-3s, containing more than most other fish, but do consumers understand enough about the amounts of EPA and DHA found in salmon and the recommended levels in our diets? IFFO’s latest video helps answer this, focusing on the crucial role of omega-3s in salmon feed, especially EPA and DHA, and the changes in levels used.
Salmon have a very limited ability to make EPA and DHA. The concentration of EPA and DHA in their flesh is directly linked to their diet, which in the wild is rich in fish oil. Farmed salmon feed used to contain 100% fish oil, rich in EPA and DHA, but supplies of sustainable fish oil are limited. As salmon farming grows, more and more feed is required but the levels of available fish oil remain unchanged, says the IFFO. The amount of fish oil used in feed is therefore decreasing and is now supplemented with an increasing percentage of vegetable oil, resulting in lower levels of EPA and DHA in salmon. Farmed salmon still contains more EPA and DHA than most other fish but consumers need to be aware of the varying levels of EPA and DHA in salmon and ensure that they continue to eat enough to reach the recommended intake levels of 250 mg per day, as recommended by the World Health Organization.
