Macronutrients are essential nutrients that provide our bodies with energy and support growth and development. These include carbohydrates, proteins, and fats. They are important for providing energy, building and repairing tissues, and supporting various bodily functions.

A varied diet consisting of different food groups ensures that your body receives a balanced intake of all essential nutrients. Diversity in foods helps prevent deficiencies and promotes optimal health.

Overnutrition occurs when an individual consumes excessive calories and nutrients, leading to weight gain and associated health problems. Undernutrition, on the other hand, happens when there is an inadequate intake of essential nutrients, resulting in deficiencies and potential health complications.
