Which three elements are classified as micronutrients?

Vitamins, minerals, and water are classified as micronutrients because they are essential nutrients that the body requires in smaller amounts compared to macronutrients, which include carbohydrates, fats, and proteins. Micronutrients play critical roles in various bodily functions, including immune response, bone health, and fluid balance.

Vitamins are organic compounds necessary for diverse metabolic processes, while minerals are inorganic substances that contribute to structural integrity and physiological functions. Water, although not a nutrient in the traditional sense, is crucial for maintaining hydration and is involved in numerous biochemical reactions in the body.

In contrast, carbohydrates, fats/lipids, and proteins are macronutrients needed in greater quantities to provide energy and support growth and development. Other options listed, such as calories (a measure of energy), sugar, sodium (a type of mineral but not a complete representation of mineral diversity), or whole food groups like fruits and vegetables, do not fit into the category of micronutrients. Fruits, vegetables, and grains are important for overall nutrition and may contain both macronutrients and micronutrients but are not classified as micronutrients themselves.
