In some ways this supports the point, in others it's the exact opposite. He says spoonfeeding information to people in bite-size chunks is like processed food and it should be hard, but you're saying that information should be spoonfed to 'smart' kids in exactly the right level of difficulty or they'll wreck their lives. Possibly it's like the concept of flow, where the standard suggestion is that things should be not too hard and not too easy, in order to keep your attention, interest and focus. But philosphically, that's just 'spoon-feeding' information in bite-size chunks like processed food, it's just varying the size of the bite to suit the level of the reciever, which again is exactly what he's saying is bad.
