Acharya Prashant advises that one does not need to take extreme measures like distancing oneself from parents or engaging in emotional quarrels over a vegan diet. He points out that since the parents have a medical background, the most effective approach is to present them with current medical facts and scientific research, which overwhelmingly support veganism. He suggests that the parents may simply need to update their knowledge with the latest research papers and journals that highlight the health benefits of a plant-based diet and the risks associated with animal products, especially for the elderly. Acharya Prashant emphasizes that this is a secular matter of health and science rather than a debate over ethics, religion, or compassion. He explains that while opinions on ethics can vary, scientific facts are established in black and white and should be used as the primary tool for communication. He concludes that instead of confronting them on principles, one should provide potent medical evidence to resolve the disagreement.
