True, but also what performance are we optimizing? Do I want to be able to run faster, hit harder, lift more, etc..?
Or do I want to live longer?
They aren't necessarily mutually exclusive, but different actions could result in different outcomes for each.
This is true, but I don't think our understanding of nutrition is good enough to really pick and choose what we want to optimize for. Eg we still don't have a recommendation on whether we should costume external vitamin K2 or not. The same goes for many amino acids. Some of the non-essential ones can have interesting effects when taken alone, eg glutamine - seems to help the gut lining. (We also don't know whether that's perfectly safe due to cancer risks, because some cancers eat glutamine.)
