Explanation:

1. Dental caries is caused by sugar fermentation by bacteria, not underconsumption; others link to insufficient nutrients (e.g., fiber for diverticulitis, iron for anemia).
2. Adolescents in rapid growth need more protein for tissue building, so protein needs depend on growth rate.
3. Basal metabolic rate typically decreases ~2% per decade after 30 due to muscle mass loss.
