In this article, we will explore the basics of nutrition, the importance of a balanced diet, and how different nutrients contribute to our health.

What is nutrition?

Nutrition refers to the intake, digestion, absorption, and utilization of nutrients present in food. These nutrients are the chemical substances that our body needs to perform all its vital functions.  

Nutrients: the building blocks of life

Nutrients are classified into macronutrients and micronutrients.  

• Macronutrients: These are needed in large quantities and provide energy. They are divided into:
  • Carbohydrates: These are the main source of energy for the body. They are found in foods such as bread, rice, pasta, and fruits.  
  • Proteins: These are essential for tissue growth and repair. They are found in meats, eggs, legumes, and dairy products.  
  • Fats: These provide energy and help absorb vitamins. They are found in oils, nuts, avocado, and meats.  
   
• Micronutrients: These are needed in small amounts but are essential for many bodily functions. They are divided into:
  • Vitamins: These regulate metabolism and help maintain the immune system.  
  • Minerals: These are necessary for the formation of bones, teeth, and tissues.
