Acharya Prashant states that one might have high academic qualifications like an MBBS, MD, or DM, but could still be quite illiterate, lacking basic knowledge regarding the nutritional value of various food products. He suggests that even a graduate from the best medical college could be a quack. He points out that many doctors are unaware that milk or meat are nowhere close to being the best sources of protein, vitamins, iron, or calcium, and that there is a lot of misinformation, even about vitamin B12. Just as everybody else needs to be educated, doctors too need to be educated because the public believes them. It is very common for a doctor to scoff at a vegetarian with a disdainful glance. This attitude, he says, is a relic of the 1950s, 60s, and 70s. The idea that one must have meat to be big and strong has entered popular culture, but it is foolish. He questions if one has ever looked at an elephant, a horse, a rhinoceros, a gorilla, or a chimpanzee, implying these strong animals are herbivores. He identifies two categories of professionals who are adept at turning non-meat-eaters into meat-eaters: ill-read doctors and totally illiterate fitness instructors. He gives an example of a fitness trainer asking a client, "You're not having chicken? How will you build mass without chicken?" He clarifies that this advice is not coming so much out of ill-intention but from the fact that the person is ill-read and simply does not know the facts. Therefore, he concludes, these people need to be educated.
