IIUC, it takes more water to produce a single almond (~7 calories) than an orange (~45 calories).

Almonds are a great source of protein. Oranges are negligible by comparison.
Almonds are a good source of vitamin E. Oranges contain none by comparison.
Almonds are high in healthy monounsaturated fats. Oranges contain none by comparison.
So now compare water per the above metrics and see where Almonds stand.
Almonds and Oranges are both unique and valuable in their own way.
A ag product should be priced to reflect their 'externalities', and that includes things like water use, but perhaps we should be subsidizing healthy stuff like produce over field corn and soybeans
Biggest problem with soy is that 77% is consumed by animal agriculture, which is causing much harm in the world (deforestation, pesticides/herbicides, runoff, biodiversity loss, co2 emissions, ...).
Almonds are closer to 1 gallon per ~6 calories - or almost 4 times worse.
It's almost as if there's reason almonds are expensive and tomatoes and oranges and lemons and limes aren't.
From what I can gather a single tomato uses on average 3.3 gallons of water and a single almond is 1.1 gallons. That is 35 calories vs 7 calories. It comes out to 10 calories per gallon vs 6 calories per gallon which is not nearly as bad as your example. I'm not saying these numbers are 100% accurate, but I'm very skeptical it is 4 times as much water.
