Have you ever tried to know what are the components in our body, animals, or any living organisms which provide us energy and give us enough energy for some particular work?

Well, as we all know the human body has a complex structure consisting of various components that make the whole human body such as muscles, organs, and bones all are composed of nutrients.

In this blog, we have explained nutrients, types of nutrients, nutrition problems, and their solutions. Let's start with what are the nutrients first.

 

What are Nutrients?

Nutrients are the compounds that are present in foods that are essential to our body, life, and health and drive the biological activity of a human body. Nutrients provide us energy and nourishment essential for the maintenance of life and growth. In a simple meaning, nutrients provide nourishment. Our body depends on what we eat and drink.

Food is the major source of all the energy needed by a body, whether it is a human or animal, or any living organism. We need energy for work, run, jump, sing, and even when we sleep. We get all the energy from the food.

Nutrients are very essential to our body and essential nutrients can not be synthesized in the cell, they will only be provided by the food. In some animals, microorganisms live in the gut and may synthesize essential nutrients, which are further released into the bloodstream.

In many living organisms, nutrients provide not only the energy required in some vital processes but also the various materials from all structural and functional components that can be assembled.

 

Different Types of Nutrients & Sources

Based on the quantity of the nutrients that every person needs to consume daily, these nutrients are categorized into two groups. These are macronutrients and micronutrients where macronutrients should be consumed in fairly large amounts, and micronutrients, which are only required in small amounts.

 

1. Macronutrients:

The name itself has a meaning that is macro means large. These are the nutrients that people need to eat regularly and in a large amount and add in a daily routine. Nutrients include carbohydrates, fats, proteins, fiber, and water.

Macronutrients are the elements in food needed for an individual to grow and function. Macronutrients provide all of the calories that your body wants and you get it from food and beverages - nutrition facts labels use macros grams to calculate what percentage calories are in the food.

Macronutrients are divided into three groups: carbohydrates, protein, and fat. Alcohol is additionally considered a macro, it provides calories, but it's not considered a vital source of nutrition, so it's often ignored when counting macros.

Each macronutrient provides a significant calorie amount per gram - 4 grams per calorie for protein and carbs, and 9 grams of calories for fat (alcohol provides 7 grams per calorie). And although all macros provide valuable energy, each macro features a different function in your body.

Have a look at different macronutrients and their sources in detail:

Carbohydrates:

Carbohydrates are essential for the body as they are needed in large amounts by the body. Up to 65% of our energy comes from carbohydrates. They're the body’s main source of fuel because they're easily converted into energy. This energy is sometimes present in the form of glucose, which all tissues and cells in our bodies readily use.

As carbohydrates are the main source, the brain, kidneys, central nervous system, and muscles need carbohydrates to function properly. These carbohydrates are usually stored in the muscles and also the liver, where they're later used for energy.

Sources: bread, wheat, potatoes of all kinds, maize, rice, cassava, Shira, pasta, macaroni, kocho, banana, sweets, sugar cane, sweet fruits, and honey. Other foods like vegetables, beans, nuts, and seeds also contain carbohydrates but in fewer amounts.

 

Proteins:

About 10–35% of calories that our body needs come from protein. Proteins are needed in our healthy diets for growth (especially important for children, teens, and pregnant women) to boost their immune functions. They also play a very crucial role in making essential hormones and enzymes, in tissue repair, preserving lean muscle mass, and supplying energy in times when carbohydrates don't seem to be available.

Pregnant women need protein to build their bodies, which of the babies and placentas, to form extra blood and for fat storage. Breastfeeding mothers need protein to make breastmilk.

Sources: eggs, breastmilk, beans, groundnuts, seeds, lentils, fish, cheese, milk, meats, chicken, etc.

 

Fats and Oils:

Fats and oils are concentrated sources of energy that are important nutrients for young children who need plenty of energy-rich food. Fats can even make meals more tasty and satisfying. Fats are classified into two groups - saturated and unsaturated fats.

The classification is important to enable you to advise your community about which fats are often consumed with less risk to people’s health. Saturated fats aren't good for a person’s health. Unsaturated fats are usually liquid at room temperature. These kinds of fats are healthy fats.

Sources: meat, chicken, milk products, butter, creams, avocado, cooking oils and fats, cheese, fish, and groundnuts.

 

Water:

Water is a part of our lives, or we can say that we are alive because of water. People can live without food for a few weeks but a person can not live without water for more than a few days. An adult body needs more than 2-3 liters of water per day. We need water for the proper functioning of our body.

We need water for our whole body to make cells and fluids materials such as tears, digestive juices, and breastmilk. Water regulates sweat from sweat glands for cooling itself. Water is also important for the production of urine, which carries waste from the body.

 

Fiber: 

Many people do not realize that fiber is a kind of carbohydrate. But fiber isn't as easily digested, and can't be absorbed by the body, making it significantly different from other carb types.

There are two main types of fiber available which we use to study, a soluble fiber that helps draw water into your gut, aiding in feelings of fullness and promoting heart health. And insoluble fiber that kind of pushes everything through, supporting digestion and regularity.

Fiber makes food bulky or bigger, this will help a person who is overweight to eat less food. Fiber makes the feces soft and bulky, this will help to prevent constipation

Sources: whole grains, beans, nuts, seeds, fruits, and vegetables.

 

2. Micronutrients:

Same as with macro, taken from its name micro means small, these are the nutrients that are needed only in very small amounts. Micronutrients are substances that do not provide any calories but enable our bodies to produce enzymes, hormones, and other substances vital to the development, disease prevention, and well-being.

Micronutrients are commonly mentioned as vitamins and minerals. And the regular intake of micronutrients helps to reduce your risk of chronic disease, promote an extended life and improve your overall wellbeing. Many research even indicates that higher intakes of micronutrients are related to improved mood, energy levels, and appetite control.

There are 26 essential vitamins and minerals from the food that each one contributes to endless bodily functions. This is why correcting even a minor deficiency during a micro can result in drastic improvements in your health and day to day life.

Vitamins:

Vitamins are a group of related substances that are produced by plants and animals. It can be classified into two groups: fat-soluble vitamins and water-soluble vitamins. Fat-soluble - vitamins are vitamins A, D, E, and K, are more easily absorbed when fat is present and can be stored in your body fat. Water-soluble vitamins are vitamin c and B vitamins that can dissolve in water. You get vitamins from the various foods you eat. Vitamins are a vital factor in your diet.

  • Vitamin A: Healing epithelial cells and normal development of teeth and bones.
  • Vitamin B: It helps in metabolism of carbohydrates, proteins and fats
  • Vitamin C: prevention of scurvy, aiding wound healing
  • Vitamin D: It is needed for absorption of calcium from small intestines
  • Vitamin E: It helps to slow down processes that damage cells, and also work as antioxidants.
  • Vitamin K: It is used for blood clotting.

 

Minerals:

Minerals are inorganic substances, meaning they're found in soil and water and aren't produced by living organisms like vitamins. Because minerals aren't easily destroyed by the elements, they can be transported from soil and water into plants and animals, and so later absorbed by you without losing their structure.

This also means they don’t deform once you absorb them. These are the substances that people need to make sure the health and proper working of their soft tissues, fluids, and their skeleton. Examples of minerals are calcium, iron, iodine, fluorine, phosphorus, chloride, potassium, magnesium, chromium, zinc, selenium, molybdenum, and sodium.

 

Why Nutrients are Needed?

Seven main essential nutrients perform different and unique functions in our body, they all are needed by the body because they work together and contribute to our healthiness. Let's know why nutrients are necessary for our body?

  • Carbohydrates: Carbohydrates are the major source of energy, that is they provide the energy of our body. Carbohydrates come from the grains, such as rice. Besides this, fruit, root vegetables, dry beans, and dairy products also contain high amounts of carbohydrates.

 

  • Proteins: Seafood, eggs, meat, fish, dairy products, dry beans, and bean products are very good sources of protein as they contain large amounts of protein. Proteins help to build, repair and maintain body tissues. We all know protein is very essential for our body to maintain good health. Regularly intake of the right amount of protein into the body will result in strong bones and good health.

 

  • Fats: Fats are present in meat, fish, seafood, dairy products, nuts, seeds, and oils. Fat also is an energy source that prevents heat loss in extreme cold weather and protects organs against any kind of shock. Fats help to make some of our body cells and transport fat-soluble vitamins in our body.

 

  • Vitamins: Vitamins help our body to grow. Vitamins take part in metabolism. Vitamin A is essential for eye health, Vitamin B1 is essential for producing various enzymes that help break down blood sugar, B2 helps to grow and develop body cells, Vitamin C is necessary for healthy skin, etc.

 

  • Minerals: Minerals are the essential nutrients that help to regulate many body functions such as fluid balance, muscle contraction, and transmission of nerve impulses. Minerals are also needed in building strong and healthy bones.

 

  • Dietary fiber: Dietary fiber helps to prevent constipation. It helps to stabilize blood sugar levels and promote gastrointestinal health.

 

  • Water: Up to 60-70% of the human body is water. The major functions of water include the production of body fluids, regulation of body temperature, transportation of nutrients from one part to another, and removal of waste products.
