Obesity and Nutrition - Level 3

For people in many countries, one of the great triumphs of modern life is that there is a great abundance of food. In those places, problems such as starvation and malnutrition are no longer prevalent, and people do not worry about going hungry. 
Despite the fact that there is plenty of food in modern countries, people still face many health problems that are related to their diet. One problem is that modern technology has made it possible to produce cheap and tasty food that is not very healthy. This leads to the problem that many people are obese, or very overweight. 
One example of this is the "fast food" that is served by many restaurants. This food is often cooked by frying. Fried food contains a high proportion of fat. Also, fast food meals are often very large. When people frequently eat large amounts of fried "fast food," they will likely eat too much fat. This excess can lead to weight gain. Of course, many people enjoy the taste of fried fast food and like to eat it occasionally. However, eating this kind of food too often is bad for one's health. 
Another example of health problems caused by modern food products involves soft drinks and other sweetened beverages. These drinks, sometimes called "pop," have a sweet taste that many people enjoy on occasion. However, these drinks contain large amounts of sugar. When people drink soft drinks very frequently, they consume a great deal of sugar. This excess sugar can lead to weight gain. 
The weight gain that can result from consuming too much fast food and too many soft drinks can have several harmful effects. For example, people who are very obese have an increased risk of heart disease and of diabetes. Of course, fast food and soft drinks are not the only causes of obesity. Other eating habits may be involved, and so are lack of exercise and genetic factors. 
To avoid the health problems that are associated with obesity, it is important that one does not eat too much food. However, this does not mean that one should try to eat as little as possible. People need an adequate amount of food in order to stay healthy. Also, it is important to avoid new "fad" diets that [bad word] popular from time to time, because these are often unsafe. Some of the diets that are [bad word] in popular books do not contain adequate amounts of nutrients, such as vitamins and minerals. 
Instead, one should try to eat foods that are nutritious. For example, foods such as [bad word]  vegetables, grains, and lean meats have many vitamins and minerals that are needed for good health. People whose diet consists mainly of these foods will probably be much healthier, on average, than people whose diet contains too many foods that have high levels of fat or sugar. In addition, many of these nutritious foods are also very tasty and enjoyable to eat!
