Essential nutrients

Essential nutrients are substances that our bodies need for normal growth, development, and maintenance of overall health. These nutrients cannot be produced by the body in sufficient amounts or not at all, so they must be obtained through our diet. There are six major classes of essential nutrients:


Carbohydrates: Carbohydrates are a primary source of energy for the body. They are broken down into glucose, which is used by cells as fuel. Good sources include whole grains, fruits, vegetables, and legumes.


Proteins: Proteins are essential for building and repairing tissues, producing enzymes and hormones, and supporting the immune system. Good sources include meat, poultry, fish, eggs, dairy products, legumes, and nuts.


Fats: Fats provide energy, help absorb fat-soluble vitamins, and are crucial for the structure and function of cells. Healthy sources of fats include avocados, nuts, seeds, olive oil, and fatty fish.


Vitamins: Vitamins are organic compounds that are necessary for various metabolic processes in the body. There are 13 essential vitamins, including vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, and vitamin K. They can be obtained from a diverse diet that includes fruits, vegetables, whole grains, and other food sources.


Minerals: Minerals are inorganic substances that are essential for various bodily functions. Examples of essential minerals include calcium, potassium, iron, magnesium, zinc, and iodine. Good sources of minerals include dairy products, leafy green vegetables, whole grains, nuts, and seeds.


Water: Water is essential for numerous physiological processes, including temperature regulation, nutrient transportation, and waste removal. It is crucial to stay hydrated by drinking water and consuming water-rich foods.


It’s important to maintain a balanced and varied diet to ensure an adequate intake of these essential nutrients. Consulting a healthcare professional or registered dietitian can provide personalized guidance on nutrient requirements based on individual factors like age, sex, activity level, and overall health.
