DeWayfarer Omega-6 isn’t only in fish, it’s actually abundant in plant foods like sunflower seeds, soy, and walnuts. Also a tablespoon of flax or chia already meets daily omega-3 needs, so you don’t need huge amounts. Plants are actually the original source of most omega fats in the food chain.
1 tbsp ground flaxseed, or
1 tbsp chia seeds, or
a small handful of walnuts
That’s it for the day.
Many people also get smaller amounts from foods like:
tofu
soy milk
canola oil
1 tablespoon ground flaxseed ≈ 2.3–2.5 g ALA
That equals 2300–2500 mgSo one tablespoon already gives more than the daily recommended amount.
Several things came together that made people believe they need large amounts of omega-3 from animal foods, even if they already eat meat. It’s less about a single conspiracy and more about how nutrition science gets simplified and marketed.
1. Marketing focuses on EPA and DHA (the fish forms)Fish and fish-oil marketing emphasizes EPA and DHA, which are the long-chain omega-3s found in fish.
Because plant foods mostly contain ALA, marketing often frames it like this:
“ALA isn’t good enough — you need EPA/DHA.”
But what usually gets left out is:
humans can convert ALA into EPA and DHA
the original source of EPA/DHA in the food chain is algae, not fish
many health organizations say ALA intake is sufficient for most people
So the messaging becomes simplified to the point of distortion.
2. Nutrition advice often gets turned into “more is better”In the 1990s–2000s, studies linked omega-3 intake with heart health. That was real science.
But the public message became:
“Omega-3 is healthy” → true
“More omega-3 is better” → oversimplified
“You must eat lots of fish or supplements” → marketing leap
This happens with many nutrients (protein is another big example).
3. Industry groups promote foods that contain the nutrientIndustries naturally highlight nutrients their products contain.
Examples:
beef industry → protein, iron, B12
dairy industry → calcium
seafood industry → omega-3
Organizations like the National Fisheries Institute promote fish partly because of its omega-3 content.
That doesn’t mean omega-3 isn’t real — just that the messaging emphasizes their products as the solution.
4. People confuse “optimal intake” with “minimum requirement”The actual essential omega-3 requirement (ALA) is small:
~1.1 g/day women
~1.6 g/day men
That’s why a tablespoon of flaxseed already covers it.
But many articles talk about higher “optimal” amounts, which can make it seem like you need huge quantities.
5. Fish-oil supplement marketing amplified the ideaThe supplement boom also played a big role.
Once fish oil became a major supplement category, the message shifted toward:
“Everyone should take omega-3 supplements.”
But large modern reviews have found mixed evidence for major benefits in the general population.
