Being allergic to many many vegetal protein source makes it hard to get good vegan meals.

Sesame seeds and tahini is used as seasoning in all the good Eastern meals i know, and nuts/peanuts consist of most of the "long lasting" snacks i know of.

Focusing on the limited remaining vegan proteins makes for a very homogeneous diet that turns out is bad for the gut biome.

I'll support anyone who wants to eat vegan, but I won't do it myself... I do reduce meat as much as my health allows.
