I’m guessing that giving babies fruit juice doesn’t help, either. The sugar promotes insulin spikes, which promote fat storage.
Probably one major factor. Even better, all that sugar is a double whammy:
- Fructose for, well, many things. Like building up insulin resistance over time, etc.

- Glucose for getting that insulin going, driving fat storage.
Fruit juices and purées are just soda / desserts with added vitamin C, that´s pretty much what you need to know.
