Reason:
1, staple food can provide more B vitamins, especially vitamin B 1.
For China residents, the main source of vitamin B 1 is the staple food, the whole grain staple food is the best, and the refined white rice flour is greatly reduced. Most fruits do not contain vitamin B 1.
The main function of B vitamins is to help the metabolism of nutrients in the body, and convert the sugar, fat and protein we eat into the energy needed by the body. If you lack B vitamins, not only energy metabolism is blocked, it is difficult to lose weight, but also dermatitis, beriberi and various nervous system diseases.
Our stomachs like warm food and hate cold and hard food.
Most fruits are cold, especially those just taken out of the refrigerator. Long-term overeating will definitely cause weakness of the spleen and stomach and affect the absorption and utilization of nutrients by the human body. Especially in the morning, drinking a bowl of porridge with temperature is definitely more nourishing than eating a big apple.
3. The fertilization ability of fruits can not be ignored.
Many fruits have high sugar content. For example, the sugar content of bananas is as high as 2 1%, and the calories of two bananas are equivalent to a big bowl of rice. Because they are sweet and delicious, they are easy to eat. Even an apple with a sugar content of about 14% is equivalent to half a bowl of rice.
Moreover, people often mistakenly think that fruit is a healthy food, which is both beautiful and healthy, and it doesn't matter if you eat too much. In fact, the fructose of fruit is more easily absorbed by the human body, which is more likely to cause abdominal fat accumulation.
4, leading to malnutrition
The trace elements in fruit are relatively simple, which is not enough to supplement the needs of human body. It is not enough to use fruit instead of staple food to lose weight. If you persist for a long time, it will even be harmful and lead to malnutrition.
Extended data:
Solution:
1, let the fruit become a supporting role. Taking 1-2 days a week and eating fruit meals can help the body detoxify, which is not bad. But don't do this every day. Usually eat a proper amount of staple food to maintain the basic needs of the body. People who are losing weight should also ensure the intake of staple food, but they can take the method of eating less and eating more meals and not eating after 5 pm.
2, eat eight points full. After lunch, the blood in the body will be concentrated in the stomach to help digestion and absorption, during which the brain is in a state of ischemia and hypoxia. Eating too much will prolong the time when the brain is in a state of ischemia and hypoxia, thus affecting the work efficiency in the afternoon.
The greater the workload, the more you need to eat dinner seriously to supplement your physical strength.
