There are more carbohydrates per kilogram in grains than there are in vegetables. Same as with meat. Grains are therefore a more dense energy source, as vegetables contain more water and fibrous tissue that is not carbohydrates.
I never said carbohydrates had more energy than protein, I said that grains contain more carbohydrates compared to vegetables.

My facts are straight.
And it was Searching that said "...and it's high time the lie stopped being spread that eating plants will improve your health over an animal-based diet."
And sorry for that single typo, I guess I should be more pedantic about my typing.
And double rereading the link again. Yeah, sorry, I missed the line where eating meat isn't a factor. So if you want to be healthy, eat more green vegetables, eat less wheat and processed wheat products and don't worry about your meat intake.
This all goes to prove another point. We all use data for our own means, to prove our own view of the way things run. If we really want to have the best life possible for ourselves, we need to get as much accurate information together as possible. People have opinions, and we use that to shape our interpretation of data. Saying that eating plants is wrong is a hugely dangerous mistake, as is telling people to not eat meat. We need to be more accurate with our information, and stop trying to push pro-meat or anti-meat agendas.
