I'm vegan and REALLY struggling with protein as I have major aversions to all protein sources, it seems, and every time I eat something I almost immediately vomit it up.
Not good times. I EVEN, in desperation, ate some dairy produce in the hope that I could find something... Alas, no.
Last night I decided to see if I could find some decent protein-shake type stuff that I could at least drink, and hopefully keep down. If you're struggling to get enough some shake or smoothie might help. I bought some hemp protein powder, which is really really delicious (it also contains a great profile of amino acids and has 12 grams of fiber per 80 cals serving). I combined it with almond milk and a banana. I also bought Amazing Meal (by Amazing Grass... I think this product is only made for Whole Foods) and made it with apple juice. It's pretty good and very nutrient dense (the protein they use is again hemp).
I've also tried rice protein powder... which is fine, but not the tastiest. Ever so often I'll use soy powder.
I have read in several books that our protein needs go from 60grams to 71grams.
