What is food? Food can be described as any nutritious substance that we eat or drink in order to maintain life and growth. Food benefits our body in a lot of ways. One of the ways that I am going to tell you about is THE NUTRIENTS PROVIDED BY FOOD TO OUR BODY.
The food that we eat everyday provides us with nutrients that we need to survive. There are seven main classes of nutrients: carbohydrates, fats, dietary fibre, minerals, proteins, vitamins and water. These nutrients can be classified into two categories. The first category is micronutrients (vitamins and minerals), which function to ensure that our body operates to the utmost level . The second category is the macronutrients (carbohydrates, fats, fiber, proteins and water), which give calories to our body but also maintain our health.


The main purpose of carbohydrates is to provide us energy to help us do our activities. This energy comes when the starch and sugars breakdown to their simplest forms which are converted into usable powers by our cells. Organs like brain and kidneys in our body specifically need a carbohydrate fuel source. 
 Examples of food rich in carbohydrates are rice, noodles, bread and other grain-based products.


Fats are highly concentrated sources of energy that is stored by our body. They supply more than twice the calories supplied per gram as a protein or carbohydrate. They provide structure to cell membranes and cushion our internal organs which helps in preventing damage to tissues. They store fat-soluble vitamins as an insurance against deficiency of these nutrients. 

Examples of foods thacontain fats are butter and olive oil.


During the process of digestion, carbohydrates that remain completely or partially undigested in our body are called fibres. They don’t give calories to our body, instead, they improve our gastrointestinal health*. It is important for our digestive health and may also reduce the risk of colon cancer. Whole grain fibres may help in reducing the risk of diabetes or to lessen insulin spikes.

Examples of fibre-rich foods are whole grains, beans and other legumes, fruits such as plums, and vegetables.


Vitamins and minerals are small molecule food components that we need in varying amounts to support our health. Vitamins help us in the production of energy, healing wounds, maintaining eye and skin health, formation of bones and also to strengthen our immunity. Minerals provide structure to our skeleton, maintain the cardiovascular health of our body and help in transmitting nerve impulses throughout our body. 

These nutrients can be provided to the body by having a well balanced diet consisting of a variety of fruits and vegetables.


Protein molecules are composed of amino acids which contain nitrogen and sulphur. Proteins are a component of all our cells and support the structure of our body. If the tissues become damaged, they are repaired with the help of proteins present in our cells. They provide antibodies so that our body can cope up with any kind of infection. In case other calorie sources are unavailable, they can be used as a fuel source for our body.

Examples of foods in which proteins are found are meats, milk and eggs.


Water is one of the most important nutrients in our diet. It regulates our body temperature and helps in the transportation of various substances in our body. It also distributes essential nutrients (such as minerals, vitamins and glucose) to cells. The waste products rejected by the cells in our body are removed with the help of water present. Water also helps in the process of digestion.
                  WHAT IS MALNUTRITION?

Malnutrition refers to insufficient, excessive or imbalanced consumption of nutrients. It can also be defined as the lack of nutrients necessary for the growth and maintenance of vital functions. In simple words, if a person does not consume the required amount of nutrients so that his/her body can function properly or when there is an excessive amount of these nutrients in his/her body, an imbalance is created, which is known as malnutrition. 

Consuming the right amounts of nutrients in their food, better known as having a healthy diet, by a person helps him/her to avoid malnutrition.


Good nutrition helps us in staying healthy, physically as well as mentally. Consuming a healthy diet provides us with energy, promotes good sleep and gives the body what it needs to stay healthy. When we make the conscious choice to eat better and healthier, we feel better about ourselves. By eating a healthy diet, we maintain our energy levels and also the blood sugar level of our body at constant. Having certain unhealthy foods may increase the risk of heart diseases and by avoiding the unhealthy food, our heart will function properly for many years that are yet to come. Eating healthy and making healthy food choices will result in a much better lifestyle. But most of us plan diet charts and cannot follow them. 

This also has a solution. 

We can start changing one eating habit each week. For example, a person has a habit of eating burgers, noodles, pizzas and other unhealthy foods. The person can start avoiding burgers in the first week, pizzas in the second week, noodles in the third and so on. This will really help him/her in having a control over his/her diet and maintain a healthy lifestyle throughout his/her life.
