I can answer questions about the relationship between spiritual and religious teachings and nutrition -- why some advocate vegetarianism (yet most don't require it), why some have an ambivalent attitude, and why some pay no attention to the subject or even reject it. Based on my research, I would generally recommend to everyone that they include some form of animal food in the diet (dairy at a minimum) because of the nutritional importance of animal foods. There is no religious tradition that requires adherents to exclude all animal foods. I cannot answer personal questions about diet as individual diet must be based on individual needs. Personal questions should be addressed to a qualified dietary or medical practitioner.
I have been studying the relationship between spirituality and nutrition for over 30 years and wrote an academic thesis on the subject. I have now completed a manuscript and am seeking a publisher.
