An innate quality of being brainwashed is that you don’t know you are. I gave up sodas in my mid-20s because my taste buds had developed enough I could sense how much they were mere liquid candy. But I remained convinced that 100% fruit juice was healthful and drank it every day when I was thirsty until about four years ago. I seriously needed to lose weight and a nutritionist clued me in that a key way to do that was stop drinking the juice-based equivalent of sodas.
Fruit juice is a scam. Been reported more and more often, but can’t be emphasized enough.
