Maybe? It's easier to believe that 100 years of massively increasing calorie density and engineering chemical perfection in terms of hitting the body's pleasure markers might have had a larger effect. That and our move to sedentary, thinking jobs. Or prolonging the day with evening entertainment, so eating later. And services that make the worst food arrive on your doorstep in 30 minutes. There are so many things above "plastics" we should blame first. But I'm sure blaming someone else is far more appetising than looking at our own lack of self control.
