Everyone knows that eating can't be wolfed down, which not only affects digestion and absorption, but also harms the human body. But do you know that chewing slowly is unhealthy?
The speed of eating mainly depends on the time of eating!
Scientific eating time
Generally speaking, eating too fast or too slow is basically unhealthy. According to the recommendations in Dietary Guidelines for China Residents, breakfast should be finished within 15~20 minutes, and lunch and dinner should be about 30 minutes, not too soon.
Eating fast is harmful.
1. Easy to get fat
The amount of fast food is not controlled by the brain, but only recognized by the mechanical receptors of the stomach. Therefore, for this white and soft food, when the stomach feels full, the diet has obviously exceeded the needs of human beings.
2. Stomach trouble
The reason why each part can digest and absorb food is because gastric acid can be combined with food and decomposed. If you eat too fast, the food can't be fully chewed and directly enters the stomach, which will cause great pressure on the stomach, so it will secrete a lot of gastric acid to help the food digest and absorb, which is particularly harmful to the function of the stomach. And eating too fast will cause food to accumulate in the stomach, which will affect the digestion speed of food in the stomach, and then lead to discomfort such as stomach pain.
3. Insufficient nutrition
Many people want to fill their stomachs faster, and what they usually eat is also very simple, which makes people unable to get enough nutrition through food. Even for convenience, many people will choose instant noodles or hamburgers in a large number of processes. For a long time, if the human body can't get enough nutrition, there will be a series of reactions such as malnutrition.
The slower you eat, the better.
Chew slowly when eating, but it doesn't mean that the slower the better, because the digestive enzymes that digest and absorb food have a secretion peak, which is generally maintained within ten minutes. This is the best time to digest and absorb food, which is conducive to the absorption of nutrients. If it takes a long time, you will probably feel that your appetite is greatly reduced and you will be full without eating anything.
How to eat scientifically
In addition to the frequency of chewing and the time of eating, there are actually several points to pay attention to when eating:
1. Eat at a fixed time
Eat regularly, and breakfast is recommended at 7-8 o'clock; Lunch11-13; Dinner 17-18. If you have a slimming plan or people with poor gastrointestinal tract and other special circumstances, you can make some adjustments if you want to eat less and eat more meals.
2. Not picky about food, not partial eclipse, not full.
Most of the nutrients needed by the human body are obtained from food, so a balanced diet every day is the foundation, so we must ensure that we are not picky eaters and partial eclipse; But don't eat too much, so as not to increase the pressure on your stomach. Just be full at seven points.
3. The food temperature is moderate
Food should be put on the dining table for 5- 10 minutes before eating, because the highest temperature that a person's mouth can bear is about 60 degrees Celsius. If the food is too hot, it will easily damage oral cavity, esophagus and gastrointestinal cells, which will increase the risk of oral cancer and esophageal cancer for a long time.
Watch your diet
Don't play mobile phone, watch TV, play games or chat while eating. Can not concentrate on eating, easy to ignore chewing food, easy to eat more.
