Last time I looked water use wasnt much more than a tomato when compared on a per calorie basis. I'd love to be shown evidence to the contrary however.
3 almonds are equivalent to 1 tomato according to this Mother Jones article (2014) [1].
AFAIK our almonds here in NL are imported, while we are known for our tomato export.
