What is the Importance of Nutrition: Everything you need to know



The food you eat has a profound impact on the functioning of your body, mind and soul. Food gives you the energy to do everything. It helps you function to the best of your ability.

Diet is what you eat, and nutrition is how your body processes what you eat. Nutrition is the science of how your body reacts to the food you eat. 

Sometimes, even if you are eating right. The body fails to absorb necessary nutrients. Failure to absorb nutrients is what causes nutritional deficiencies. 

Why does this happen? The study of nutrition explains this and provides solutions.


Nutrition and Health

Sometimes our body fails to absorb the necessary nutrients from the food we eat. This causes nutritional deficiencies and health problems. Here are a few things you can do to reverse that:

  • Detox your body 

The body cannot absorb nutrients from the food because it is filled with toxins. The toxins are accumulated in the small and large intestines. This prevents the body from absorbing nutrients. 

When you detox and clean your body from inside, it again begins to absorb nutrients from food. Ever wonder why you don’t feel energetic even after eating the right foods?

This is because of the toxicity and obstruction in your body. A deep detox will solve the problem of malabsorption. And will help you live a healthy and vibrant life. 

After detox, you may notice, you don’t need to eat as much as you were eating before. Small portions of food make you feel full. This is because your body has again started to absorb necessary nutrients and is now functioning correctly. Let’s begin with understanding the different types of nutrients.


Types of nutrients

Nutritionists divide nutrients into two major categories:

  • Macronutrients 
  • Micronutrients 



Fats, proteins, carbohydrates and water are macronutrients. They are called macronutrients because we need them in large amounts. 


Fats are essential micronutrients. Here are some of the benefits of fats:

  • They help in lubricating joints. 
  • Fats also help organs produce hormones. 
  • Healthy fats help the body absorb specific vitamins. 
  • Eating healthy fats also reduce inflammation
  • They also improve brain health 

However, consuming too many fats can be harmful. Trans fats and saturated fats are very heavy on the body. They can cause heart diseases, heart attacks. This is because they increase LDL (bad cholesterol) and blood pressure. 

It is better to eat unsaturated fats. There are two types of unsaturated fats:

  • Monounsaturated fats
  • Polyunsaturated fats

Monounsaturated fats are present in olives, peanuts, nuts, seeds and avocados. Polyunsaturated fats are present in walnuts, flaxseeds, fish and sunflower oil. 


Proteins are made up of essential chemicals known as amino acids. Protein is an integral part of each cell in the body. The body uses proteins for various purposes like:

  • Growing and maintaining the body. The main component of hair and nails is protein. 
  • The body builds and repairs tissues with protein.
  • Protein provides the necessary material to produce enzymes and hormones.
  • Your bones, cartilage, teeth, skin, blood and muscles. They are all made up of proteins.

Proteins are made up of 20 amino acid. These amino acids are essential. Our body produces some of them and some, we get from our food. 

However, consuming too much protein can be harmful. Too much of it can cause kidney problems, heart diseases and high cholesterol. So, enjoy your proteins in a healthy amount.

You can get healthy proteins from fish, beans, nuts and whole grains. 


We all love carbs. The delicious potato chips, pies and muffins are rich in carbohydrates. But they are not healthy carbohydrates. 

Sugar, fiber and starch are three types of carbohydrates. Some of them are healthy, and some are not. 

Fiber is a complex carbohydrate. And sugar is a simple carbohydrate. It is easy for the body to break down sugar. That is why sugar provides instant energy. 

However, too much processed sugar can cause diabetes. It can also increase blood pressure and cause cancer. Natural sugars, on the other hand, are supremely healthy. 

Fruits and dry fruits are excellent sources of natural sugars. 

There are two types of fiber:

  • Soluble fiber 
  • Non-soluble fiber 


Soluble fiber takes some time to break down and digest. Whereas, non-soluble fiber doesn’t break down. It remains intact. Both types of fibers are essential for optimum health. 

Non-soluble fiber helps clean the digestive tract. It makes the elimination process smooth and easy. Soluble fiber turns into a gel and slows down the digestion process. So, the body can absorb the required nutrients from the food.

You can get healthy carbohydrates from quinoa, oats, bananas, blueberries, oranges and kidney beans.


Water is one of the most essential macronutrients. Our body is 70 per cent water. It is a macronutrient because we need it in large amounts. Without water, there would be no life. 

Doctors and nutritionists recommend drinking at least 2 litres of water every day. However, beware of drinking too much water. Research suggests that drinking too much water can also be harmful. 



Micronutrients are also essential nutrients. They are called micronutrients because we need them in small amounts. 

Vitamins and minerals are two types of micronutrients. Our body needs them to function at its best capacity.


Our body has 13 kinds of vitamins. They are as follows:

  • Vitamin A, C, D, K, and E
  • Biotin
  • B-12
  • B-6
  • Niacin
  • Folate
  • Thiamine
  • Pantothenic acid
  • Riboflavin


These 13 vitamins are essential to the body. You can get them from sunlight, healthy foods and supplements. 

Vitamins are also classified into water-soluble and fat-soluble. Vitamin A, E, D and K are fat-soluble vitamins while the rest are water-soluble. 


Minerals make up 4 per cent of the body’s mass. There are 103 minerals in the human body. However, a few of them are classified to be essential minerals. They are as follows:

  • Iron
  • Potassium
  • Magnesium
  • Copper
  • Sodium
  • Calcium
  • Zinc
  • Selenium 
  • Manganese 


All of these are essential minerals. They are naturally produced by the body. Different types of fruits, vegetables, whole grains, lean meats and lentils are healthy sources of minerals. 




Swedish Physicist Elina Berglund Develops ‘Natural Alternative’ To Birth Control Pills

While modern birth-control techniques are considered ‘effective’, there are still side-effects to consider. Girls as young as 12 can be prescribed birth control by doctors and only learn about the threats they do years later. Swedish nuclear physicist Elina Berglund Scherwitzl wanted to develop a method of contraception that did not damage hormonal cycles. She created an alternative called ‘Natural Cycles’ that used a combination of research and advanced math. It is an app-based algorithm that identifies when exactly the ovulation period occurs during the cycle. This way, a woman would need to use protection or abstain from sexual intercourse during this period alone.

Canada Approves ‘Magic Mushroom’ Therapy For 4 Dying Cancer Patients

Canada’s top doctor has approved the use of Psilocybin, commonly referred to as ‘magic mushrooms’ to relieve the pain of four individuals suffering from terminal cancer. Patty Hajdu, the country’s health minister introduced a new exemption the Controlled Drugs and Substances Act since psilocybin has been illegal in Canada since 1974. Studies have proved that the psychoactive components in psilocybin can ease anxiety and pain, especially in those with terminal illnesses.

Release Built-Up Stress That’s Stored In Your Body

A technique known as Craniosacral Therapy is a powerful way to allow your body to relax better. It helps your parasympathetic nervous system to gently function in a non-invasive manner. The more you use touch as a means of nervous resonance, the more stress you gradually melt away. This form of therapy, although considered ‘alternative’ allows the synarthrodial joints of the cranium to smoothly palpate. You will be able to alleviate a wide variety of dysfunctions from strokes to sport injuries.

Go Bananas on Bananas!

Bananas, especially Burro Bananas, are chock-full of nutrients that aid in digestion and help relieve blood pressure imbalances. They should be a staple regardless of what kind of diet you are following. Pregnant women are especially benefited by the consumption of bananas as they help relieve morning sickness during the first trimester. Bananas are also a great source of folate, which is necessary for the development of the baby’s brain and spinal cord.
