For protein? really?
Not only is jello grosss - since it's really just ground bovine hoof, water, sugar, artificial flavors and colors - but how would it ever qualify as a protein source?
Plus, so many great protein options exist. In addition to soy protein sports drink mixes or bars, there are nuts, tofu, dehydrated legumes, quinoa and couscous, etc.
So much better and so easy to carry!
