Diana Hsieh has a great read over on Modern Paleo on “three major obstacles” — the value of health, individual differences, and the science of nutrition — that make it difficult to categorize essential vs optional paleo principles:
Of course, we can define a paleo diet, because it means something definite. We can also identify the general principles of a paleo approach to health … That’s crucial for doing paleo well, I think.
Yet to think of some of these principles as universally “essential” versus universally “optional” would be a mistake. Instead, they should stand in our minds as “more or less important for me.”
Do read the whole post! BTW, I’ve been in my new digs for a week and a half and hope to be back to a regular posting schedule fairly soon. Thanks for your patience.
