Directly and indirectly.
Buying decisions from parents was influenced. Advertising influenced people. School lunches. What parents would feed other kids after activities. Habits of people "never giving it a second thought" were still being shaped by these forces. Even if someone only thinks about it a fraction of the time, it moves the needle. If my mom ate 10% more processed carbs than her parents and passed those habits to me, I was impacted. Rinse Repeat for 60 years.
