For instance, Vitamin C boosts the immune system, while calcium is essential for bone health. Ensuring an adequate intake of micronutrients is crucial for preventing deficiencies that can lead to health issues. Overall, eating a balanced diet rich in whole foods helps meet micronutrient needs for optimal health.
