There is also a "standard posture" for eating.

01. Eating standing: affects taste

A study published in the Journal of Consumer Research found that body posture affects people's perception of food.

The University of South Florida has conducted in-depth studies on the relationship between vestibular perception (the brain area responsible for balance, posture, and spatial positioning) and the taste perception system through a number of experiments. It was found that compared with sitting people, participants who were eating while standing had generally poorer evaluations of taste.

Research and analysis point out that when people stand, more blood enters the lower body due to gravity, and the heart rate increases, trying to pump blood back to the upper half of the body.

This process activates the hypothalamus, pituitary gland, and adrenal glands, leading to increased levels of the stress hormone cortisol.

This chain reaction will reduce sensory sensitivity and affect people's taste, temperature and overall perception of food and drinks. Even standing for only a few minutes will affect the taste buds and ruin a meal.

02. Eating lying down: cause abdominal distension

Some people may watch TV or play on their mobile phones, while lying on the sofa to eat snacks. The MSN website in the United States summarizes the article, try not to lie down and eat snacks. Eating snacks while lying in bed will greatly increase the chance of bloating.

James Reynolds, a professor of clinical medicine at the University of Pennsylvania in the United States, believes that gas will enter the lower abdomen if you lie in bed at night and chew food. You should sit up straight before eating.

03. Squatting and eating: affect gastrointestinal digestion

When eating, people who are used to squatting on a chair to eat think that this posture seems more comfortable.

In fact, when the body is squatting, a part of the blood will be distributed to the muscles of the lower limbs, which cannot fully supply the stomach and intestines.

For most people, there will be some tension in the local muscle groups when squatting, and the stomach and intestines will also be squeezed, which can not make the gastrointestinal function play a better role.

In addition, squatting to eat will accelerate physical fatigue, and the speed of eating will increase involuntarily. The food is swallowed without being chewed slowly, which will increase the burden on the gastrointestinal tract. It is more likely to cause indigestion over time, and even gastric ulcers may occur in severe cases. And other diseases.

In addition to the above eating positions, eating with a hunchback, eating at a low table, or sitting on a sofa will squeeze the abdomen to a certain extent, affect the digestion of food, and may induce stomach problems over time.

The correct eating posture should be to sit with your back straight and leave plenty of room for your abdomen.

Scientific diet, there is a sequence

Drinking soup before or after meals depends on physical fitness. For people who want to lose weight, you can drink soup before meals to increase the feeling of fullness; for patients with chronic atrophic gastritis and gastric ulcers, it is best to drink soup after meals.

Eat vegetables first, then meat. Vegetables contain a lot of dietary fiber, which can enhance satiety. Eating vegetables first can reduce the intake of meat and starchy foods.

Eat fruit after a meal. Eat fruit and eat immediately. The sourness and sweetness of the fruit stimulate excessive gastric acid secretion, which may cause other substances in the fruit to combine with gastric acid to form stones.

These 6 diet details, be careful to damage the digestive system

In addition to eating posture and order, eating must avoid some details that can detract from health.

1. Don't eat it while it's hot

Although the food tastes more delicious when eaten hot, long-term overheated diet can induce a variety of digestive diseases such as esophageal cancer.

The wall of the esophagus is very delicate and can only tolerate food at 50~60℃. If the temperature exceeds this temperature, the esophageal mucosa will be burned. If this happens repeatedly, it may cause qualitative changes and develop into tumors.

Recommendation: The most suitable food temperature is neither cold nor hot, and it is better to eat it at around 40°C.

2. Don't → eat while watching TV

Pay attention when eating, and it is best to turn off distractions such as the TV. This is also conducive to adequate chewing, which is convenient for weight control and avoids the risk of chronic diseases.

3. Don't talk about things while eating

It’s okay to talk about everyday things at the dinner table, but if you talk about work, business, or test scores while eating, it may hinder the digestion and absorption of food.

This is because when people are concentrating on thinking or are under great mental stress, autonomic nerve function is suppressed, blood supply in the digestive tract is reduced, and gastric peristalsis will slow down.

Suggestion: For people with weak digestion and absorption, eating wholeheartedly, relaxedly and happily can help the food to be fully digested and absorbed.

4. Don't eat with emotions

Eating with negative emotions such as anxiety and anger can also harm your health. Negative emotions may reduce gastrointestinal function and cause indigestion; it may also promote the secretion of gastric juice with high acidity and high pepsin, which can easily damage the gastric mucosa.

Medical research has found that nervousness will increase the level of adrenaline, thereby destroying the gastric mucosal barrier, which is an important cause of peptic ulcer and gastritis.

Recommendation: It is important to adjust your mood quickly when eating.

5. Don't → gobble it up

Without chewing, the brain has not reminded the stomach and intestines to be ready to receive food, and the stomach will be filled all at once, which can easily cause digestive and metabolic disorders.

Moreover, it is not conducive to grasping food intake, which is likely to cause obesity.

Suggestion: Eat at least 15 minutes of each meal, especially for the elderly, it is best to chew more than 20 times in one mouthful.

6. Don't mix and match hot and cold alternately

Eating a bite of hot dishes and drinking a cold beer or drink gives people a refreshing feeling, which is a favorite match for many people nowadays. But doing so can easily cause gastrointestinal discomfort.

A cold and a hot irritates the stomach strongly, easily causing indigestion, causing stomach cramps or stomach pain, and over time may induce gastritis or enteritis.
