Nuts definitely consume a lot of water, but your usage link compares per kg. When you adjust for calories it tells a different story, e.g. Almonds [0] have around 3x more calories per kg than Steak [1].

You're right, comparing just the weight doesn't tell the whole story. However, the same is true for calories. I think you should consider a kg of "weighted average" beef and not just steak, as steak tends to be lean. You would also have to take into account nutrients. That's why I'm not a huge fan of just comparing how much water different food need. Things are more complex than that.

  Agreed - I think it would be better to just compare an overall diet of someone eating more plants vs less plants, then sum up their water usage. I’d have a hard time believing that overall eating fewer animals resulted in higher water usage (since those animals had to eat plants to grow), but would be interesting to see data on it.

I agree too, but I don't think water falling from the sky on non-arable land is the same as using potable water for agriculture. I think those two should be counted separately.

IMO the criterion to compare by should be protein content (also taking into account the https://en.m.wikipedia.org/wiki/Biological_value https://en.m.wikipedia.org/wiki/Biological_value) rather than calories. For most people suffering from malnutrition worldwide their biggest problem probably isn't getting enough calories but rather getting enough protein and vitamins and so on. Getting calories in the rich countries is more of an anti problem. Many people take in too many calories, because there's too little protein in the foods they eat (so they have to eat more of it, giving them too many calories). Protein dilution.

Now do water per gram of complete protein
