With the accelerated pace of life, for office workers, supper almost has become the main meal during the whole day. People always eat too much nutritious and rich food at supper. However, they have not realized that such a habit is very unhealthy to human body. Experts point out that, improper supper may lead to five diseases.

1. High blood pressure:
Eating too much meat at supper not only will increase the burden on the stomach and intestines, but will also increase the blood pressure in the body. Besides, as the speed of blood flow will slow down during sleep, so a lot of blood will deposit on the vessel wall, thus leading to atherosclerosis and high blood pressure. Scientific evidence shows that, people who always eat meat or fish at supper are more likely to suffer from high blood pressure and obesity than those vegetarians.

2. Cardiovascular diseases:
Compared with breakfast and lunch, we should eat less at supper. In general, the calories provided by the supper should not exceed 30% of the total calories during the whole day. If the body takes in too much calories at supper, it will increase the level of blood cholesterol. At the same time, it will also stimulate the production of low-density lipoproteins, and accumulate the excessive cholesterol on the artery wall. This is one of the major causes of atherosclerosis and cardiovascular diseases.

3. Diabetes:
If the middle-aged or elderly people always eat too much food at supper, it will repeatedly stimulate the secretion of a large number of insulin. This will often result in the early failure of islet cells, and thus leading to diabetes.

4. Dreaminess:
Eating too much at supper will cause great pressure on stomach, intestines, liver, gallbladder, pancreas, and so on. When this information is transformed to the brain, it will make the corresponding brain cells active, thus resulting in dreaminess or nightmare. This may often make people feel tired. With a long time, it can even cause diseases such as neurasthenia.

5. Obesity:
If you eat too much food at supper, the concentration of glucose, amino acids and fatty acids in the blood will increase, thus promoting the secretion of a large number of insulin. People always do little exercise at night, so the excessive heat will synthesize into a large number of fats under the action of insulin, which makes people gradually gain weight. As a result, the supper should be simple and light, and the intake of calories should not exceed 30% of the total calories throughout the day. This is beneficial for the prevention and control of obesity.
