@ddnomad @BuddyTheBeefalo Omega-3 is an EFA, not an amino acid. It also isn't an issue if you get fats in their whole form (i.e. flax seeds instead of flax oil) as far as I understand.
The only actual deficiency that is present in a balanced whole foods plant based diet is B12, and that is a product of modern sanitation practices (dairy has it btw b/c cows are fortified with it as I understand it). Easily satisfied with a Vit B12 supplement or nutritional yeast.
@ddnomad @BuddyTheBeefalo Vitamin D is the other one, but that's true for *everyone* (it's why both dairy and plant-based milks are fortified with D3) and there are, again, supplements if necessary (this one is necessary for pretty much everyone not living near the equator).
Otherwise, nutritionally, a WFPB diet is pretty much the most balanced and nutritious (esp for long-term health) diet one can have.
