Quotes to ponder:
"Ultra-processed foods commonly have added flavors, sugars, fats, preservatives and ingredients that you are unlikely to have stocked in your pantry."
"When the subjects ate from the ultra-processed buffet, they consumed about 500 calories above their baseline intake and they gained about 2 pounds in two weeks."
"Processing changes the food structure (matrix), and this impacts satiety, the feeling of fullness that persists after eating."
