A balanced diet
Today, weight problems, heart trouble and many forms of cancer are becoming more common because of unhealthy diets. Everywhere, people are thinking about how they can eat more healthily. There are many different answers to this question. Some people think that sugar is bad for your health. Others say that sugar is the best source of energy. Some people eat meat while others were vegetarians. It is difficult to say who is right.
Most doctors agree on one thing, however: you need a balanced diet to stay healthy. A balanced diet means eating various foods from each of the five food groups: grains, vegetables, fruit, milk products and meat. The importance of having various foods in your diet is quite clear. Doctors warn us that a lack of certain kinds of foods is dangerous. Your body cannot work properly without a balanced diet. On the other hand, having too much of anything, including your favourite food, is dangerous too. Doctors say, for example, if people eat lots of food such as cheeseburgers and butter, they are likely to become fat. This may increase the risk of a heart attack.
Therefore, to help you decide what to eat and what not to eat, you should do some research. Scientific information about your body’s needs for fats, proteins, minerals and vitamins can help you decide on the right things to eat and the right amount to eat. It can also help you understand your body better. If you learn how to balance your diet properly, you will have a healthier future.
