Acharya Prashant addresses a questioner's concern regarding doctors and dieticians prescribing animal products like milk, meat, and eggs even in prestigious medical institutions. He explains that doctors and medical professionals generally follow social norms and acceptance. If a society does not socially accept a certain product, such as beef in India, a doctor will not prescribe it regardless of its potential medicinal value. Conversely, in societies where it is accepted, like America, it is commonly prescribed. He emphasizes that any nutrient or chemical compound required by the human body can be obtained from multiple sources or synthesized in a laboratory. There is no absolute biological necessity to rely on animal-derived sources for health.
