Have shortcomings. Accidentally ingesting too much carbohydrate will not cause too much harm to the body, but it will be difficult to digest and increase the burden on the gastrointestinal tract. However, long-term excessive intake of carbohydrates will lead to physical abnormalities and even diseases, such as obesity, diabetes, hypertension and so on. Carbohydrate refers to carbohydrate. When people eat too much carbohydrate, it will be converted into fat and stored in the body. However, excessive fat storage will lead to obesity and elevated blood lipids.

In addition, excess carbohydrates will be converted into glucose in the blood. When the excess glucose in blood exceeds the normal metabolic capacity of human body, it will lead to the increase of blood sugar, the disorder of blood sugar and lipid metabolism, and the increase of blood viscosity and blood pressure. The "three highs" population is a high incidence group of cardiovascular and cerebrovascular accidents, and the incidence of myocardial infarction, cerebral infarction and cerebral hemorrhage is high in this population. Therefore, we should also limit the intake of carbohydrates in daily life.

The disadvantages of high carbohydrate diet are also obvious. First of all, long-term high-carbohydrate diet leads to large fluctuations in blood sugar, which in turn leads to obesity, which should be the knowledge of fitness professionals and nutrition and health care professionals. Under the present dietary conditions, people are less and less hungry, thinner and eat more and more. This is mainly because most people's diet is high in carbohydrates, and they have no energy and time to exercise, which leads to the inability to gain weight continuously. Long-term high-carbohydrate diet will lead to many diseases, such as diabetes and cardiovascular diseases. Third, a high carbohydrate diet affects the work efficiency of mental workers. A high carbohydrate diet directly leads to an increase in postprandial blood sugar, while the brain that feeds on sugar is full of energy because of the existence of food. But one of the characteristics of carbohydrates is that they are easy to digest. When the sugar is used up, the brain will fall back into an uncomfortable state called "brain fog", resulting in dizziness, inattention and desire for more sugar.

A high carbohydrate diet is not healthy. Reducing the intake of carbohydrate diet, increasing the intake of fruits and vegetables, protein and healthy fat, and adopting a more scientific diet are more conducive to health. High levels of free sugar can inhibit the synaptic development of the brain, lead to cognitive defects, reduce the concentration of brain-derived neurotrophic factor (BDNF), and reduce the performance of memory and cognitive function. However, relatively speaking, the process of starting to digest carbohydrates like whole grains is slow and complicated, because they contain different nutrients, such as sugar, protein, vitamins and minerals, so they offset the harm caused by high sugar. Even so, it should be moderate.
