I also don’t like the emphasis on meat protein. Small amounts of meat protein a few times a week are definitely healthy for most people, but organic (not soaked in pesticides) beans, lentils, etc. are almost certainly a healthy way to consume extra protein.
I sense the ugly hand of the meat industry in realfood.gov. I think if more people understood how (especially) chickens and pigs are tortured in meat production, it would help people who are addicted to excess meat cut back on their consumption to just what they need for good health.
EDIT: the documentary movie The Game Changers (2018) is an excellent source of information. The scenes interviewing huge muscular vegetarian NFL football players really put the lie to the ‘must have meat’ addicts. That said, I still think small amounts of meat protein are very healthy for most people.
