Because of the busy work and high pace of life, modern people pay less and less attention to their daily diet. Over time, they will easily form some bad habits in dieting. These bad habits are not only very harmful to their body, but may also cause premature senility.

The first bad habit: eating instant noodles for breakfast.
Often eating instant noodles for breakfast is very harmful to the health and development of human body. Because the human body needs six categories of nutrients to maintain its normal physiological metabolism, but the main component of instant noodles is carbohydrate. It lacks of other essential nutrients. As a result, if you eat instant noodles as breakfast for a long time, it will cause dizziness, lack of energy, palpitation, and so on. If it is severe, it can even cause weight loss, muscle atrophy and other symptoms of malnutrition.

The second bad habit: drinking mineral water instead of plain boiled water.
Many people think that mineral water contains a large number of minerals, so they can replace plain boiled water by mineral water. However, they rarely know that mineral water may also be contaminated by the harmful substances in the land. Recently, the Dutch scientists find out that mineral water is more vulnerable to the contamination of harmful microbes and bacteria. Although these bacteria may not cause great threat on human body, but for those whose immunity is relatively weak, the bacteria contained in bottled mineral water may cause serious danger on their body.

The third bad habit: eating livestock meat instead of fish.
Many people like eating livestock meat rather than fish. Although the amount and absorption rate of protein contained in these two kinds of food are similar, but the constitution of fat is different. The fat in fish contains certain polyunsaturated fatty acid, which plays a beneficial role in the development of children's brain and in the prevention of cardiovascular disease. While livestock meat, especially red meat, mainly contains saturated fatty acid, which is not beneficial to human health.

The fourth bad habit: eating fruits instead of vegetables.
Both fruits and vegetables contain plenty of vitamins. Therefore, many people think that, as long as they eat some fruits every day, they can eat less or even do not eat any vegetables. In fact, vegetables are essential to human body. They can effectively promote the absorption of proteins, fats and carbohydrates by the body. If people only eat animal food, the absorption rate of protein is only 70%, but if they eat vegetables at the same time, the absorption rate can reach 90%. Moreover, the plant crude fiber and pectin contained in vegetables can stimulate the bowel movement, so it has the function of promoting digestion and preventing intestinal cancer.
