anytime we eat ANYTHING, insulin rises, that's normal and healthy. nobody is saying it's not. but that is a far cry from the krazee spike induced by a 34 oz. blizzard or a box of oreos. what people ate pre-agriculture and pre-industrial society vs. our choices with grocers and restaurants and pepsico and general mills is like another world. they ate what was available, during the seasons and common to their area. western people now face choices of food so processed, so jacked with sugars and industrial oils and SO CHEAP it would boggle the mind of somebody from even 100 years ago, never mind 1,000 or 20,000.

have some bacon slathered in butter and calm down.
