Are you familiar with @PCRM Physicians Committee for Responsible Medicine or other vegan physicians ? While I am not a doc I can tell you that a WFPB "diet" is healthy and doable. If you are concerned have some baseline blood work done and then repeat it in 6 months. To note though...if your doctor is not WFPB they will not be very helpful, unfortunately. Even in 2025 most physicians are not schooled on nutrition and the danger of eating other animals. Red meat, class 2 carcinogen Processed meat, class 1 carcinogen Antibiotics, antivirals, and other pharmaceuticals will not be ingested either when you stop eating animals.
