Just got back from visiting two friends of mine. I offered to take them out to a nice dinner, their choice.
It took them over two hours to choose a restaurant.
Once we got there,
a gluten-free organic vegan restaurant, they looked at the menu and said, "We can't eat here. There isn't enough protein." So we walked down the street to a vegetarian Mexican restaurant.
They perused the menu for over an hour, asking the server all kinds of questions like what kind of beans are these, are they organic, are they locally sourced, how are they prepared.
They finally chose something and were apparently satisfied with it, but when they got home they each took a dozen or more vitamin pills, kelp pills, fiber pills, god knows what else. Apparently, the purity of their food is more important than the purity of their vitamins, which according to research only rarely contain the listed ingredient and instead contain all sorts of harmful heavy metals.
The whole "religion" -- and that's what it is -- of veganism and guten-freeism is not based on fact or science or research. It's a self-sustaining cult.
Shoot me if I ever go vegan or gluten free.
