What Is the Importance of Nutrition? Is It Critical for Good Health?

Nutritional wellness, a term that you must have come across when you googled “How to stay healthy?”, is less daunting than it appears.

Nutritional wellness is essentially just focusing on improving your health through diets, this would include incorporating a balanced nutritious diet in your daily life.

Importance of Nutrition

Now that we’re more acquainted with what nutritional wellness means, let’s dig deep into the importance of nutrients in our bodies.

An overall healthy diet constituting all the nutrition our body might require, will not only help the body function efficiently but will also increase your longevity.

If you’re into sports, then nutrition becomes all the more essential, because consuming the right foods can prevent sports-related injuries like muscle cramps, ligament tears, muscle fatigue, etc.

Potassium is especially known to prevent muscle cramps; so now if you find an athlete snacking on a banana, you know why! (1)

Pregnancy can be draining and exhausting, it only makes sense to provide your body with the best for all that it is doing.

Consuming all the essential nutrients like folic acid, calcium, vitamins, etc. will not only help your body cope but will also prevent any birth defects and birth complications.

It will also ensure the proper development of the fetus. (2)

New lactating mothers also have to keep a close eye on their nutrition because what you eat determines the energy, protein, nutrient, and vitamin content of your breast milk, and this, in turn, determines the health of your baby.

As a parent, it’s only natural to prioritize your baby, however, another reason for new mothers to watch their food intake is that their bodies would have undergone an immense amount of trauma and blood loss. 

To avoid any deficiency of health complications that might occur after childbirth, it is important to consume a healthy diet, one which contains protein, calcium, iron, and vitamins, both for the sake of the mother’s health as well as that of the baby’s. (3)

Now when pregnancy and lactation are out of the way, watching your child’s intake becomes your primary concern.

The right nutrition at a young age will not only help in their development, but it will also help establish a good foundation for healthy eating habits and nutritional knowledge, and imparting this knowledge is one of the most important things one can do for their child! (4)

This knowledge could affect the food choices they make when they are an adolescent. During this period, the body goes through various changes; one might even say it’s evolving!

To keep up with your body, it is vital to feed it nutritious food, food that is rich in carbohydrates, fats, proteins, vitamins, and minerals.

Adolescents require twice as many nutrients than an adult because this is the period where they gain around 40% of their adult weight and 15% of their adult height! (4) (5)

Nutrition is a vast subject to cover, however, there are 6 essential nutrients that you must be aware of!

  • Carbs

Carbs are short for carbohydrates, a large group of organic compounds that you find in foods, and living tissue.

Sugars, starch, and fiber are all a type of carbohydrate.

They are ideally broken down to release energy in the human body. They also fuel your brain, kidneys, heart muscles, and central nervous system.

  • Protein

Proteins are essential macronutrients that are also known as the building blocks of body tissues, and muscles. It also helps in fueling the body since it can provide as much energy density as carbohydrates.

A major function of this nutrient is to help maintain your bones, muscles, cartilage, and skin. It also plays a role in various other functions of the body like digestion, oxygenation, and regulation.

  • Fats

Fat is also a nutrient that helps fuel the body. It comes in several forms, saturated, monounsaturated, polyunsaturated, and trans. 

Monounsaturated and polyunsaturated fats are known as the “good fats”; this is because they are good for your heart, your cholesterol, and your overall health.

The fat stored in our body helps store energy while also keeping us warm. They also absorb all the fat-soluble vitamins and help store them in our bodies.

  • Vitamins 


Vitamins are organic substances present in minute quantities in various foods; our bodies cannot synthesize them, and hence consumption through foods rich in vitamins is essential.

There are two types of vitamins, water-soluble and fat-soluble.

Water-soluble vitamins can not be stored in the body, and any excess will be passed out in the form of urine. Fat-soluble vitamins can be stored in the body for days and, at times, months. They are stored mainly in fatty tissues and the liver.

Vitamins are essential for the proper functioning of our body.

Specific vitamins help absorb other nutrients; vitamin C helps absorb iron from plant foods, and vitamin D helps absorb calcium. Apart from aiding in absorption, vitamins also help convert food into energy, building and maintaining our bones, teeth, muscles, skin, and hair. They also ensure the efficient functioning of our brains, eyes, nervous and immune systems.

  • Water

An inorganic, transparent, taste, and odorless chemical substance, water, is as essential to our body as it is to plants.

Water helps keep our body hydrated while also regulating body temperature, and maintaining other body functions like excretion.
