Definition of nutrients
Nutrients are essential compounds that our bodies need in order to function properly and maintain good health. They are substances that provide energy, promote growth and development, and enable various bodily processes. Nutrients are divided into two main categories: macronutrients and micronutrients.
Role of nutrients in the body
Nutrients play a crucial role in maintaining optimal health and well-being. They are involved in various bodily functions, including metabolism, growth and repair of tissues, and the maintenance of a strong immune system. Proper intake of nutrients ensures that our bodies receive the necessary energy and building blocks to carry out these functions efficiently.
Macronutrients
Macronutrients are nutrients that our bodies require in large amounts. They provide energy and are necessary for the proper functioning of our organs and systems. The three main macronutrients are carbohydrates, proteins, and fats.
Carbohydrates
Carbohydrates are the body’s primary source of energy. They are broken down into glucose, which is used by our cells to produce energy. Carbohydrates also play a role in maintaining stable blood sugar levels and providing dietary fiber, which aids in digestion and promotes bowel regularity.
Proteins
Proteins are essential for growth, repair, and maintenance of tissues in the body. They are made up of amino acids, which are the building blocks of proteins. Proteins are involved in various bodily functions, including the production of enzymes, hormones, and antibodies. They also play a role in the transportation of nutrients and oxygen within the body.
Fats
Fats are another important source of energy for our bodies. They play a vital role in the absorption of fat-soluble vitamins and the production of hormones. Fats also provide cushioning for organs and insulation for the body. There are different types of fats, including saturated fats, monounsaturated fats, and polyunsaturated fats, each with their own unique properties and functions.
Micronutrients
Micronutrients are nutrients that our bodies require in smaller amounts, but are equally essential for maintaining good health. They include vitamins and minerals.
Vitamins
Vitamins are organic compounds that are vital for various bodily functions. They are involved in the production of energy, the formation of red blood cells, and the maintenance of healthy cells, tissues, and organs. There are thirteen essential vitamins, each with their own specific roles and functions.
Minerals
Minerals are inorganic substances that are essential for the proper functioning of our bodies. They play a role in enzyme activity, fluid balance, and the maintenance of healthy bones and teeth. Minerals are classified into two categories: macrominerals and trace minerals, depending on the amount our bodies require.

Carbohydrates
Types of carbohydrates
Carbohydrates can be classified into two main types: simple carbohydrates and complex carbohydrates. Simple carbohydrates are made up of one or two sugar molecules and are quickly digested and absorbed by the body. Examples of simple carbohydrates include table sugar, honey, and fruits. Complex carbohydrates, on the other hand, are made up of multiple sugar molecules and provide a slow and steady release of energy. Examples of complex carbohydrates include whole grains, legumes, and vegetables.
Functions of carbohydrates
Carbohydrates are the body’s preferred source of energy. They provide fuel for the brain, muscles, and other organs. Carbohydrates also have a sparing effect on proteins, which means that they prevent the breakdown of proteins for energy. Additionally, carbohydrates provide dietary fiber, which aids in digestion, promotes satiety, and helps regulate blood sugar levels.
Food sources of carbohydrates
Carbohydrates can be found in a wide variety of foods. Good sources of carbohydrates include fruits, vegetables, whole grains, legumes, and dairy products. It is important to choose carbohydrates that are rich in fiber and nutrients, and to avoid foods that are highly processed and high in added sugars.
Proteins
Types of proteins
Proteins can be classified into two main types: complete proteins and incomplete proteins. Complete proteins contain all the essential amino acids that our bodies require, while incomplete proteins do not. Animal-based proteins, such as meat, fish, eggs, and dairy products, are considered complete proteins. Plant-based proteins, such as legumes, grains, nuts, and seeds, are considered incomplete proteins, as they may lack one or more essential amino acids.
Functions of proteins
Proteins play a crucial role in the growth, repair, and maintenance of tissues in the body. They are involved in the production of enzymes, hormones, and antibodies, which are essential for various bodily functions. Proteins also aid in the transportation of nutrients and oxygen within the body and contribute to the structure and strength of muscles, bones, and skin.
Food sources of proteins
Proteins can be found in both animal and plant-based foods. Good sources of animal-based proteins include lean meats, poultry, fish, eggs, and dairy products. Plant-based sources of protein include legumes, grains, nuts, and seeds. It is important to consume a variety of protein sources to ensure an adequate intake of all essential amino acids.
Fats
Types of fats
Fats can be classified into different types based on their chemical structure and properties. Saturated fats are solid at room temperature and are commonly found in animal-based products, such as meat, butter, and cheese. Monounsaturated fats and polyunsaturated fats are liquid at room temperature and can be found in plant-based oils, such as olive oil and canola oil. Trans fats are artificially produced fats that are commonly found in processed foods, including packaged snacks and fried foods.
Functions of fats
Fats are an important source of energy for our bodies and help us absorb fat-soluble vitamins, such as vitamins A, D, E, and K. They also play a crucial role in hormone production and help regulate body temperature. Fats provide cushioning for our organs, protect nerves, and contribute to healthy cell membranes.
Food sources of fats
Fats can be found in a variety of foods. Good sources of healthy fats include avocados, nuts, seeds, olive oil, fatty fish (such as salmon and mackerel), and plant-based oils. It is important to consume fats in moderation and choose healthier sources to promote overall health.
Vitamins
Types of vitamins
There are thirteen essential vitamins, each with its own specific roles and functions. These vitamins can be classified into two categories: fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins (vitamins A, D, E, and K) are absorbed and stored in fat, while water-soluble vitamins (vitamins C and the B-complex vitamins) dissolve in water and are not stored in the body for long periods of time.
Functions of vitamins
Vitamins play a crucial role in various bodily functions. They are involved in energy production, the formation and repair of tissues, the production of red blood cells, and the maintenance of a healthy immune system. Each vitamin has its own specific functions and benefits for overall health and well-being.
