Theory:

The different nutrients that can be classified as:
  1. Macronutrient
  2. Micronutrient
Macronutrient:
Macro means large, and macronutrients are thus require in larger amounts or quantities. Macronutrients include:
 
1. Carbohydrates
2. Fats
3. Proteins

1. Carbohydrates:
  
These are substances which act as the main energy source. It includes breads, fruits, grains, sugar and vegetables.
 
2. Proteins:
  
These are substances that form the main structural components of cells and helps in building the body tissue. Low-fat meat like chicken, beans, eggs, green leafy vegetables are good sources of protein.
 
3. Fats:
  
It s a source of energy that is consumed to increase the absorption of fat-soluble vitamins.
Micronutrients
Micro means small, and micronutrients are nutrients required in small amounts. They include:
  1.  Minerals and 
  2.  Vitamins

1. Vitamins:
  
They provide structure to the blood vessels, ligaments and bone. 
Example:
Fishes, carrots, spinach, nuts etc., are some of the sources of vitamins
2. Minerals:
  
They are some of the elements required by the body for its proper functioning.
Example:
Phosphorus, potassium, sodium, chloride, magnesium
Division of nutrients
Given below is a simple pie chart decorated with a corresponding food item. It depicts that we don't require all the nutrients in the same quantity. This chart explains quantitatively how much one should consider the type of nutrients in their food.
 
Nutrients present in the food:
  • The maximum part of the pie diagram is filled with carbohydrate and proteins
  • The position of fat is limited with few food items.
Compared to fats, carbohydrates are more in quantity as they are rich in starch and give quick energy. Fats do have a lot of energy but in concentrated form, due to which they take a lot of time to get digested. Hence, the amount of fat in the food we consume should be less than the carbohydrates.
In addition to this, we should also consume protein-rich food like meat, milk and sprouts. Protein-rich foods build the body and protects it from diseases. Fruits are rich in vitamins and minerals that help the body to function smoothly.
