5 groups of people should not eat and drink at the same time
The habit of eating and drinking at the same time not only affects digestion but also tends to cause weight gain, especially harmful to people with certain health problems.
According to Dr. Giang Quan - Head of the Department of Gastroenterology, Beijing Changgung Tsinghua Hospital (China), a recent study published in the journalAppetiteAmerican, said that drinking water while eating will make you eat more without knowing it, silently causing weight gain.
In the study, 44 adults ate lunch once a week in the lab for a total of four weeks. For each meal, they ate only pasta, in four weights: 400g, 500g, 600g and 700g, with an additional 700ml of water at the meal.
According toGG, the authors recorded how much each person ate each time and videotaped the participants' meals to count the number of times they switched between eating noodles and drinking water.

The results showed that regardless of the amount of water, participants who drank while eating increased their food intake. On average, food intake increased by 5.7 grams for each additional drink of water during a meal.
Researchers suggest that frequent switching between food and drink weakens the feeling of satiety, leading to increased consumption. Satiety is the feeling of satisfaction with a given amount of food that decreases when people eat a given amount of the same food, leading to a feeling of fullness.
Not only does it reduce the feeling of fullness, drinking too much water during meals can also affect your digestive system:
- The stomach contains high concentrations of gastric acid to digest food. Drinking a lot of water will dilute the gastric acid, affecting digestion.
- When eating, with a large amount of food taken in, the stomach will take on the function of temporary storage. However, the stomach volume is limited, after drinking a lot of water, the space in the stomach will shrink, become tense, the stomach wall will enlarge, easily causing nausea, bloating and other uncomfortable feelings.
The stomach wall in a state of high tension for a long time will cause diseases such as reduced stomach motility and gastritis.

Five types of people should not eat and drink at the same time
1. Patients with gastroesophageal reflux
Patients with gastroesophageal reflux have lower esophageal sphincter insufficiency. Drinking a lot of water while eating can easily increase pressure in the stomach, causing stomach contents to reflux into the esophagus, worsening symptoms of acid reflux and heartburn.
2. Elderly people
The digestive function of the elderly is weak, stomach motility is reduced, drinking too much water when eating can easily cause stomach discomfort, not good for digestion.
3. Children
The stomach cavity of children is very small, if drinking water at the same time can lead to insufficient food intake, causing malnutrition. Therefore, when eating, children should not drink more than 300ml of water and soup.
4. Diabetic gastroparesis patients
Diabetic gastroparesis, also known as delayed gastric emptying, is when the movement of food from the stomach to the small intestine is slowed or stopped even though nothing is blocking the stomach or small intestine.
In this condition, the vagus nerve that controls the muscles of the stomach and small intestine is damaged, causing food movement to slow or stop. Other cells in the stomach may also be damaged, causing the stomach to stop emptying its contents.
Patients are prone to nausea and upper abdominal discomfort after eating, these patients should drink as little water as possible while eating.
5. People with dental diseases
People with dental diseases cannot chew food thoroughly due to problems such as pain when chewing, tooth loss. If you drink a lot of water while eating, the food will not be chewed thoroughly, after swallowing it will increase the burden on the digestive tract, increasing the risk of chronic gastritis.
So what is the right way to drink water when eating rice?
According to expert advice, you should drink water before eating, ideally half an hour and drink 1 hour after eating. This allows hydrochloric acid enough time to properly digest food and prevent the formation of gas, acid and bloating.
