What is the effect of nutrition on overall functioning during middle childhood?

What will be an ideal response?

A good answer would include the following key points:
- The level of nutrition children receive during this time impacts many aspects of their behavior.
- For example, Guatemalan villages show that children's nutritional backgrounds are related to several dimensions of social and emotional functioning at school age.
- Children who had received more nutrients were more involved with their peers, had less anxiety, and more positive emotion, than their peers who had received less adequate nutrition.
- Nutrition promotes bone growth and healthy teeth.
- Nutrition is linked to cognitive performance as well.
