Nutrition is a key component that helps our bodies function and keep working for us to stay alive; if we didn’t receive any nutrients from the food we consume, we would not be able to nourish our cells that require vitamins and minerals to regulate chemical processes. For instance when we eat cheese, the proteins (amino acids) help build up our tissues and muscles, while the carbohydrates (glucose) are used to replenish and energise our bodies. However, eating and drinking certain foods and liquids (cakes, cheese, soda) can harm the body when consumed to a detrimental extent. A ‘diet’ is the sum of foods consumed to keep the body fit and healthy, and is a term generally used when people intend to lose weight or become more fit and healthy. Therefore, this article will try to explain why people should eat healthy foods, and how they can benefit us. Although, before we can explore how diets help, we need to first determine what nutrition is and how it plays an integral role in our life.

Nutrition helps our body by providing the substances that help our bodies function, this includes breathing, digestion and keeping our average body temperature at 37.5 degrees celsius. Nutrients are categorised into 7 ‘major nutrients’: fats, proteins, carbohydrates, dairy, vitamins, minerals and water. These nutrients help build parts of our bodies, produce mandatory power and heat energy, and overall keep the body in working order. For instance, whenever we consume foods such as cereals or potatoes, a carbohydrate called ‘starch’ enters our body and then later breaks down into glucose molecules; this glucose molecule enters our bloodstream and is then distributed to nearly every cell in the body including  the organs, muscles, and brain.
