> This article isn't correct. The human body synthesizes DHA from short-chain omega-3 alpha-linolenic acid (ALA), which can be found in things like hemp, flax, algae, pumpkin seeds, etc. That's true, but is that pathway effective enough to effectively provide what the body needs for optimal function? IIRC, the ALA -> DHA pathway is quite rate limited. > I have a hard time believing anything said about the need for certain kinds of nutrients. I've done all-cheese diets, all-meat diets, and all-plant diets for months on end with no serious side effects other than constipation and boredom of eating a monodiet. The human body is resilient and doesn't need to be fed as much as people think. I don't think a few anecdotal short-term experiments with extreme diets say much about what the human body needs to function well. The human body can be somewhat resilient in the face of malnourishment, but it doesn't follow from that malnourishment is an acceptable state. It's sort of like this: If you've got a four-server cluster for your application, would you rather it be in a state where two offline due to hardware failures, or would you rather they all be functioning normally? The former might be an example of "resilience," but your users might also be experiencing slowness issues due to the reduced capacity.
