Micronutrients are vitamins and minerals essential for maintaining health and supporting bodily functions. Unlike macronutrients that provide energy, micronutrients play diverse roles, including supporting immune function, bone health, and cellular processes. They are crucial for metabolism, energy production, and neurological functions. Micronutrient deficiencies can lead to various health issues, underscoring the importance of a balanced diet rich in fruits, vegetables, whole grains, and lean proteins to ensure adequate intake.
