We all know that food is medicine to the human body. Food is generally any substance ingested to give nutrition to an organism. The human body requires a variety of food sources to satisfy the needs of its different organs and systems. Food is generally of animal, plant or fungi origin, and usually contains vital nutrients, including proteins, carbohydrates, vitamins, or other minerals. We also need certain substances such as oxygen, carbon dioxide, water and various hormones to survive.
A wide range of food is required for our survival. This process of gathering food from the environment in a natural manner is called “nutrition” and is necessary to supply energy to the body tissues, as well as to serve as a source of food for the various organs. Therefore, a healthy diet is essential to maintain a healthy human body, with a well-balanced diet consisting of a wide variety of carbohydrates, protein, fats, vitamins and minerals. However, food can be classified into several types:
Carbohydrates or main food groups include sugar, starch and fiber. These three food groups are usually the basis of the majority of the diets worldwide. Energy from carbohydrates is stored as fats in the body. Consequently, fat is used as a source of energy by the body, even when food does not get stored in the body (through carbohydrates) – such as in case of excessive weight loss or weight gain.
The carbohydrates are divided into two categories: simple and complex. Simple carbohydrates consist of glucose, sucrose, simple sugars and flour. Complex carbohydrates consist of different kinds of non-simple carbohydrates such as rice, corn, pasta, cereals, legumes, vegetables and fruits.
Each type of food has different effects on the human body. Although some foods do not have negative effects on human health, many people have difficulty eating enough food to meet their daily requirement and lead unhealthy lives. As a result, there are many people who suffer from obesity and overweight problems. Eating too much food results in poor weight management, which causes many people to become unhealthy. According to most nutritionists and dieticians, a good body weight is around 17% of the body mass.
