Yes the diet has changed a lot as the diabetes has gotten younger, but don't forget what the 50s was like when people drank kool-aid and used margarine and it's not like we didn't have those things plus tons of packaged crap and fast-food in the 70s either. I ate a lot of pop-tarts and cereal with skim milk and sugar growing up. Don't forget about Tang. This dietary change has been going on for a while, and yes it has been increasing, but it has been a long time that people have not been eating real food because fake food (not to mention stuff like DDT) was associated with "Progress". When it first came out, it didn't seem to hurt people of my parent's generation. It hasn't harmed me as much as some of the younger folks on this forum. I've been eating the same dwarf hybrid wheat as everyone else my whole life. The harm seems to be accumulating. Even all those kids nearby me in wealthy Montecito with their pasty skin and pudgy bodies and vegan chefs don't look normal.
