What nutrient is typically low in adolescents' diets, potentially affecting their health?

The answer identifies calcium as a nutrient that is typically low in adolescents' diets, which can have significant health implications. Adolescence is a critical period for bone health, as the majority of bone mass is built during this time. Adequate calcium intake is crucial to support this growth and development. Insufficient calcium can lead to decreased bone density and increased risk of fractures and osteoporosis later in life.

Calcium deficiency during adolescence may arise from dietary preferences, such as reduced consumption of dairy products or other calcium-rich foods, as well as increased dietary restrictions or emphasized calorie content over nutrient density. Therefore, focusing on improving calcium intake through accessible food sources, such as fortified foods, leafy greens, and dairy alternatives, is essential for promoting optimal health in adolescents.
