Back in the 70's when living in southern CA I worked for a very wealthy family while going to school. This is where I learned about processed foods. I did clean up for the cook (dishwasher) Fresh produce and fruit was delivered every morning. One of the dairy farmers brought dairy twice a week. The lady of the house was perfection in my young eyes and I hung on her every word about foods to be prepared and what her kids were allowed to eat. I never got out of the kitchen area and that's all she talked about when she came to the kitchen. She was serious about her food. I never saw a box of mac and cheese, deli meats, chips, white bread, sweetened cereals, or packaged snacks like cookies. She said she'd pick dandelion leaves before spending money buying poison for her family's health. I grew up on a farm and I thought I was unlucky to have nothing but garden stuff and raised meats to eat and here these people ate nothing else and less of it.
