Is Jin Jiankang Nutrition Self-promotion Station a Lie?

Absolute scams often advertise (or may be fabricated) with a far-off coincidental and effective patient, aiming at deceiving middle-aged and elderly people and patients with chronic diseases. It seems that doctors nowadays (whether western medicine or Chinese medicine) don't understand nutrition and health care, but they don't understand it either. They are all professionals. It's incredible that they sell people like this. Without systematic study, they can cure all diseases. Does it conform to the law of medical development?
