This document discusses the classification and sources of macronutrients and micronutrients important for human nutrition. It outlines that nutrition consists of macronutrients like carbohydrates, proteins and fats that provide energy, and micronutrients like vitamins and minerals that are essential in smaller amounts. Common sources of carbohydrates include grains, potatoes and fruits, while proteins come from both animal sources like meat and eggs and plant sources like beans and nuts. The document also examines deficiency symptoms and functions of each macronutrient and micronutrient group.
