@InfraBlue,
My take is a "Boooooooo". I think they think most people think Meat when they say Protein.
Infrablue is correct, you can get Protein from Veggies and Grains and Fruit and Dairy.
(It's tough to do in isolation. I had a friend who decided to be a fruitarian, eat only fruits. Right. Then it was pointed out that in a six ounce (170gram) chicken breast there are about 50 grams of protein where in a six ounce banana there are 2. You have to eat a lot of fruit to get enough Protein.)
Anyway, we need to come up with a better chart for them.
