This is the kind of advice my grandma swore by. High starch, sugar as a topping for fruits and "healthy, whole grain" cereals. No red meat. No butter. Olive oil and omega-3 enhanced light margarine.
She died of pancreatic cancer - a disease that has been strongly linked to sugar consumption. Not really a surprise, considering that the pancreas is also the primary organ affected in diabetes - also strongly linked to sugar consumption.
I just don't understand why the idea of eating real food, in forms that you can find in nature, without pre-processing, is so controversial.
