Spinach is definitely a vegetable, not a lettuce - it's got more to do with the acid/base balance than the nutritional info.

My coach just pointed out that I haven't been having any lettuce. I was under the impression that since there is no nutritional value that is why it is unlimited and therefore not including it in my diet. My coach pointed it that it is also good "eat our water" as much as we drink it. Which makes sense with insoluble fiber and bowel motility. If that helps any

I might have one lettuce salad in a week and my coach hasn't said I need to eat more lettuce. I do drink well over the 64 oz of water in a day though.

Oooh, that's interesting!
