Nutrition
Nutrition is a simple yet wide term if we go for its meaning. The definition of nutrition involves:
- Selection and preparation of the food that is needed for growth and life
- Ingestion of food (to eat or drink something)
- Assimilation of food by the body (the biology of inhalation, composition, and absorption of the food)
In simple language, nutrition is all about using the food in bodybuilding, body mechanism, growth, and getting energy.

Nutrients or Constituents of Food
There are two types of nutrition. Food constituents or nutrients are broadly classified into a list of two categories.
Macronutrients
Nutrients that our body needs in a larger quantity. These are used as energy resources and provide material to build our building blocks or body structure. Though the energy production or generated internal energy through these macronutrients depends on absorption and digestion efforts.
Macronutrients are:

Micronutrients
Nutrients that our body needs in small quantity, but are important for smooth and efficient body processes. They influence body systems maintaining the coordination between various body processes. Not only this, but they also ensure the proper consumption of energy and promotes self-defense.
Micronutrients are:
- Vitamins (Fat-soluble, Water-soluble)
- Minerals (Calcium, Magnesium, Iron, Potassium, Sodium, Copper, Manganese, Chromium, Cobalt, Nickel, Phosphorus, Zinc, Iodine, Selenium, Chloride, Molybdenum, Fluoride, Sulpher, Selenium)
- Trace elements
Water
Water is not involved in the list, but however, the content will remain incomplete if we do not mention this very important fluid.
Importance of Nutrients
Food is an incomplete term without macro-nutrients and micro-nutrients, which support health and life. They are stored in the form of energy, fat, and muscle mass, and that’s why a person can survive for 2-8 weeks without taking food. Poor nutrition or malnutrition results in less productivity or poor performance, whereas good nutrition promotes growth and development.
Where nutrition can save one from various chronic diseases, lack of them or poor diet can show its adverse impact on health too. It may cause one to suffer from:
- Deficiency diseases: Kwashiorkor and scurvy
- Unhealthy conditions: Metabolic syndrome and obesity
- Common systemic chronic diseases: Diabetes, osteoporosis, and cardiovascular
