Fish are regularly contaminated with PCBs and other pollutants, with bioaccumulation and biomagnification providing significant doses; this includes heavy metals.
Or you could skip the downsides and get those nuts and seeds and other plants with omega-3 fatty acids… or just algae based supplements (algae are the origin of the nutrient for those fish).
Nuts and seeds have way too many Omega 6 fatty acids, wich counteract Omega 3 and can cause heart problems
A vegan keto diet is hardly possible because of that
Omega 3 (ALA, a predecessor of EPA and DHA which you also need) comes from few plants in high concentrations: flax (linseed), hemp, chia
Additionally, microalgae oil for direct EPA and DHA can help, as the transformation of ALA in the body only fulfills the basic needs
A vegan diet needs a bunch of essential supplements, which you can take in a single pill like these a day as they are small. Others like iron, protein, B-Vitamins come with a diet rich in legumes and full grains.

So it’s a tradeoff: Fish consumption, methylmercury and child neurodevelopment - PMC

They don’t do it. It’s like I’m talking to a bot.
What? That was just an example. Nuts are not that healthy as a main part of the diet
You are right, but nuts and seeds are also more expensive.

Start subsidizing growing nuts and seeds at the same level as the subsidies for the fishing sector, and let’s compare prices then.
