In our quest for a healthy lifestyle, we often come across the term “nutrients.” But…
- What exactly are nutrients?
- Why are they so important for our bodies? and
- What are the six essential nutrients
Basic nutrients are substances found in food that are essential for growth, development, and overall well-being. They provide the building blocks for our cells, support bodily functions, and help maintain optimal health.
In this article, we will explore the 6 essential nutrients that your body needs, their sources, functions, and the health benefits they offer.
Why are Nutrients Important for the Body?
Basic nutrients are crucial for sustaining excellent well-being. The human body requires 6 nutrients to maintain optimal health and function. Here are some key reasons why nutrients in food are important:
- Energy Production: Nutrients provide the energy needed for physical activity, growth, and metabolism.
- Growth and Development: Nutrients in food support the growth and development of tissues, organs, and overall body structure.
- Maintenance and Repair: Nutrients help maintain and repair cells, tissues, and organs that undergo wear and tear.
- Immune Function: Nutrients support a healthy immune system, helping to fight off infections and diseases.
- Cognitive Function: Nutrients play a crucial role in brain development, memory, concentration, and overall cognitive function.
- Overall Well-being: The 6 nutrients in food contribute to overall well-being by preventing nutrient deficiencies and promoting optimal health.
Macronutrients vs. Micronutrients
What are the nutrients that contribute to a healthy and balanced diet?
These 6 essential nutrients are broadly categorized into macronutrients and micronutrients.
- Macronutrients are nutrients that the body requires in large quantities. They include proteins, carbohydrates, and fats, and they provide energy (calories) to fuel the body.
- Micronutrients are nutrients in food that the body needs in smaller amounts. They include vitamins and minerals, and they are essential for various physiological functions, such as maintaining a healthy immune system and supporting enzyme activity.
Now, let’s delve into each of the essential nutrients, their sources, functions, and health benefits.
Major Food Nutrients || Sources & Functions
The first component of 6 nutrients. Proteins are the building blocks of life, playing a crucial role in the growth, repair, and maintenance of tissues in the body. They are made up of amino acids, which are essential for the synthesis of enzymes, hormones, and antibodies. Here are the main functions and health benefits of protein:
- Building and repairing tissues
- Enzyme and hormone production
- Antibody formation for a strong immune system
- Transportation of important nutrients and oxygen in the blood
- Helps regulate blood sugar levels
- Supports muscle growth and recovery
- Promotes healthy hair, skin, and nails
- Provides a feeling of fullness, aiding in weight management
Major Food Sources
Carbohydrates are the body’s primary source of energy. They are broken down into glucose, which fuels our cells, muscles, and brain. Carbohydrates also play a role in maintaining proper organ function. Here are the main functions and health benefits of carbohydrates:
- Energy production
- Storage of energy for future use
- Facilitation of brain and nervous system function
- Sustains energy levels throughout the day
- Supports physical performance during exercise
- Provides essential fibre for a healthy digestive system

Fats often receive a bad reputation, but they are an essential nutrient required for various bodily functions. They provide a concentrated source of energy and aid in the absorption of fat-soluble vitamins. Here are the main functions and health benefits of fats:
- Energy storage
- Protection of organs
- Insulation and temperature regulation
- Absorption of fat-soluble vitamins (A, D, E, and K)
- Regulate hormone production
- Supports brain function and memory
- Assists in the absorption of fat-soluble vitamins
- Provides a sense of satiety and satisfaction after meals
Major Food Sources
Vitamins are basic nutrients for normal growth, development, and overall health.
Water-soluble vitamins: These vitamins play essential roles in energy metabolism, immune function, and the formation of collagen and red blood cells.
Fat-soluble vitamins: These vitamins are crucial for vision, bone health, cell growth, and immune function.
- Boosts immune system
- Supports healthy skin and hair
- Enhances vision and eye health
