Nutrients- Overview, Significance, Types and Sources


What are Nutrients?

Nutrients are compounds that the body needs for growth, survival, and good health. Our body cannot make these nutrients on its own in sufficient quantity so we need to get these nutrients from outside sources such as food and dietary supplements. 

Nutrients are the building blocks for restoration and growth and substances necessary to regulate chemical processes for the proper functioning of the body.

While there are a ton of essential nutrients that are required for the proper growth and functioning of the body but on a larger scale, we can divide these essential nutrients into two categories as Macronutrients and Micronutrients.

What Are Macronutrients?

Macronutrients are the nutrients that are required in large amounts by our bodies. They are the building blocks of our diet and contain nutrients like carbohydrates, protein, and fats which are necessary for the growth and proper functioning of the human body.

They consist of a significant chunk of our diet and they are the one who provides us constant energy to do our daily activities. The power from macronutrients comes from their chemical bonds and then that energy is converted to cellular energy which is utilized by our body to perform work.

Protein is a  macronutrient that is comprised of chains of subunits called amino acids which are called the building blocks of protein. Amino acids are only subunits composed of oxygen, carbon, hydrogen, and nitrogen.

Proteins secure the growth and development of muscle, skin, bones, and hair and the repair of tissues. They help you fight infection by creating antibodies and other essential substances.

Your body uses additional protein for energy as they serve as a fuel source for cells and tissues when required. Protein provides 4 calories per gram.

Fats are further divided into two major categories:

Saturated fats

Saturated fats are solid at room temperature and are occasionally called solid fats. Increased intake of saturated fat may eventually raise levels of low-density lipoprotein (LDL) cholesterol in the body, which increases the risk of cardiovascular disease and stroke.

Unsaturated fats

Unsaturated fats are fluid at room temperature, and they are mostly acquired from plant oils. Sources of unsaturated fats contain olives, nuts, and avocados.

Carbohydrates are the sugars that supply energy for all the cells and tissues in the body. They are the main source of energy and support in providing fuel to the body to carry out daily activities.

Carbohydrates fuel our brain and nervous system and defend against disease and should make up 45 to 65 percent of your total daily calories, according to the Dietary Guidelines.

The fruit, vegetables, dairy, and grain food groups all include carbohydrates. Numerous foods with carbohydrates also supply fiber. Fiber is a sort of carbohydrate that your body cannot digest.

It is grounded in numerous foods that come from plants, including vegetables, fruits, nuts, seeds, beans, and whole grains. There are two distinct types of carbohydrates: 

Simple Carbohydrates 

Simple carbs are sugars as they easily break down and transform into glucose which our body uses for quick energy.

They are not suitable for your body as they spike up your insulin which can be associated with a lot of diseases like diabetes and high blood pressure. So it is advisable to ingest them in a limited amounts. 

Complex Carbohydrates

Complex Carbohydrates are more beneficial than simple carbohydrates as they are high in fiber and digest slowly so our body can use them for a longer time. Due to fiber, they are perfect for people with type 2 diabetes as they help in managing blood sugar levels. 

Healthy Sources of Carbohydrates

  1. Oats
  2. Whole grain bread
  3. Sweet potato
  4. Brown Rice

You don’t have to sip lots of water to stay hydrated. Fruits and vegetables can also be a great source. Munch on some spinach or watermelon to remain hydrated.

The most reasonable way to know if you’re properly hydrated is the volume and color of your urine. If your urine isn’t regular and pale yellow or nearly clear, you need more water in your diet.

So It’s significant to have water in your diet in adequate amounts to avoid dehydration as even mild dehydration can make you feel tired and impair your concentration and physical performance.

Micronutrients are nutrients that are required by the body in small amounts as they indirectly support in carrying out essential functions of the body.

 They don’t deliver energy to the body unlike the macronutrients but they assist in the process by being part of enzymes that catalyzes chemical reactions in the body from producing energy to digesting nutrients to building molecules.


Micronutrients are divided into two further categories:

  • Vitamins
