blog author name

The secret to our health is nutrition. And we all know that a balanced diet helps to improve our immune system. It also makes us productive by reducing the chances of getting sick. However, our overall health will be hampered if we don’t eat properly.

The same goes for the students who are studying nutrition. They have to feed themselves with learning and research during their study. And most of them struggle to find good research topics at the end of their term. Hence, we have jotted down around 100+ nutrition topics for your assistance.

But first, attain some basic knowledge!

What is Nutrition?

Nutrition is an essential component of health and growth. Stronger immune systems, safer pregnancies and deliveries, a decreased chance of non-communicable diseases (like diabetes and cardiovascular disease), and longer life spans are all associated with better nutrition.

Healthy kids learn better. Proper nourishing people are more creative and can progressively open doors to end the cycles of hunger and poverty.

Every type of malnutrition poses serious risks to human health. Undernutrition and overweight are major causes of malnutrition globally, particularly in low- and middle-income nations. Malnutrition can take many different forms, such as undernutrition, a lack of vitamins or minerals, being overweight or obese, and the ensuing non-communicable illnesses that are brought on by poor diet.

The worldwide burden of malnutrition has severe and long-lasting effects on people and their families, as well as on communities, nations, and the economy.

The Types of Nutrition

Types of Nutrition

Autotrophic Nutrition

The phrase autotrophic nutrition combines two words: ‘auto’ (self) and ‘trophic’ (nutrition). This type of organism includes a green pigment called chlorophyll that traps energy from the sun.

Heterotrophic Nutrition

Heterotrophic organisms cannot make food independently and must rely on animals and plants for food. This group is divided into three groups based on the food and feeding method.

Classification of Nutrients

Food contains over 40 distinct types of nutrients, which can be broadly classified into the seven major groups listed below:

Classification of Nutrients

Why are they necessary for our bodies?

Although each of the seven main groups of nutrients serves a different and distinct purpose in our bodies, they are all necessary because they work together to promote our health. The following are the primary functions of these major nutrients:

Necessary For Our Bodies


Carbohydrates are a significant energy source in our bodies, primarily derived from grains like rice and noodles. Carbohydrates can also be found in fruits, root veggies, dry beans, and dairy products.


Protein-rich foods include meat, fish, seafood, eggs, dairy products, dry legumes, and beans. Its primary tasks include forming, repairing, and maintaining healthy body tissues.


Fats can be found in various meals, including meat, seafood, fish, dairy products, seeds, nuts, and oils. Fats are a source of energy. They safeguard organs from shock and avoid heat loss in extremely cold weather. They are in charge of forming a portion of our body cells and transporting fat-soluble vitamins such as A, D, E, and K.


Vitamins come from various food groups and play various roles in body metabolism, such as keeping healthy skin and hair, building bones, and releasing and utilizing energy from foods. Water-soluble vitamins and fat-soluble vitamins are the two types of vitamins.


Minerals are a class of important nutrients that control many bodily processes, such as fluid balance, muscle contraction, and nerve impulse transmission. Calcium, for example, contributes to the bodily structure and the formation of strong and healthy bones.

Dietary fibre

Dietary fibre is an indigestible component of plants. It aids in blood sugar regulation, gut health, and constipation prevention. Soluble and insoluble fibre is two types of dietary fibre.


Water is the most abundant substance in the human body and an important nutrient for our health. Water’s primary duties include bodily temperature regulation, fluid production, nutrient transportation, and waste removal.
