Case in point: the Mayo Clinic article titled "Are you getting enough protein?"[0]
It claims that protein is only a concern for people who are undereating or on weight loss drugs, yet it cites protein recommendations that many people find challenging to meet (1.1g/kg for active people, more if you're over 40 or doing strength or endurance workouts.) To top it off, it's illustrated with a handful of nuts, which are pretty marginal sources of protein. It's bizarrely mixed messaging.
