Without food you will not be able to live long. You eat different kinds of foods such as bread, rice, meat, etc. You also take liquid foods like milk, soups and fruit juices. Whatever may be the food, it is made up of small units, which keep you healthy and fit. One of the saddest features of the modern world is that millions of people do not have enough to eat and many more do not have the right kinds of food required for good health. In order to be healthy, man needs a balanced diet, i.e. a diet that contains the right amounts of protein, fat, carbohydrate, vitamins and minerals. The carbohydrate in bread, rice, potatoes and sugary foods provides energy for the body. Too much carbohydrate, however, can make people obese and obesity can endanger health. These people usually have serious health problems since they are extremely fat. The oils and fats in milk, cream, butter, cheese and meat provide the body’s main stored food and contain much more energy than carbohydrates. The protein in cheese, eggs, meat, fish and milk quickens growth and repair damage to the body’s tissues. The body also needs small amounts of vitamins and minerals. When a persons diet consists of a variety of foods, the required amounts of vitamins and minerals are taken in. Historically, the diets of different societies depend on such factors as climate, soil and the ease or difficulty of transporting foods from one place to another. The simple diet of the Bedouin Arabs consists of dates, grains and sometimes meat and vegetables. This is because the land is very dry and, as a result, very few foods can be grown there. On the other hand, a country such as France, with a good climate and rich soil, has always had plentiful and a great variety of foods.en-USinşaat mühendisliğigıda mühendisliğicivil engineeringfood engineeringmasterThesis
