4 reasons why Coach Park banned U23 Vietnam from eating and using phones at the same time

In addition to discipline regarding time, clothing, internal information, and interviews, Coach Park also requires players not to use their phones while eating or in meetings.

Explaining from a medical perspective, Dr. Tu Ngu, General Secretary of the Vietnam Nutrition Association, said that eating while using the phone is very bad for the digestive system.

Digestive disorders

Dr. Tu Ngu analyzed that, according to conditioned reflexes, at mealtimes, gastric juices from the mouth to the stomach are secreted to support better digestion of food. Therefore, one should eat at a certain time to form a reflex.

When eating, if you only focus on eating, your brain will devote all its energy to this task, focusing on digesting food, but when you eat while using your phone or watching TV, your brain will be divided.

At that time, secretions will decrease, limiting the body's natural activities, limiting conditioned reflexes, causing the digestive process to decrease.

Easy stomach ache

Eating while using the phone will also reduce concentration. Instead of chewing enough times before swallowing, sometimes you swallow it all before you even have time to chew.

While right from the moment food enters the mouth, the saliva in the mouth helps decompose a lot of glucide there, helping to tear the food into small pieces.

“If you eat carefully, when it reaches the stomach, along with stomach contractions, digestive juices, and hydrochloric acid, it will help the digestion process better, the stomach will not have to work too hard, reducing the risk of inflammation and ulcers,” Dr. Tu Ngu analyzed.

Reduced nutrient absorption

When food reaches the stomach, it opens when it has enough acidity and is sent down to the duodenum for absorption into the body. If the food in the stomach is soft enough, as soon as it reaches the first part of the duodenum, many nutrients are absorbed, including glucide.

In case of unfocused eating, food is not fully digested, making it more difficult and takes longer to absorb nutrients.

Risk of weight gain

Eating without concentration can easily lead to uncontrolled eating and not knowing when you're full. I should have eaten 2 bowls and stood up, but I was so engrossed in watching that I kept eating.

“Many times when I meet children, I often ask them what they ate today, but they say they don’t know because they are too busy looking at their phones. When they eat like that, they don’t know what is delicious, they can’t even chew,” Dr. Tu Ngu shared.

In addition to harming the stomach, causing inflammation, and reducing absorption, Dr. Tu Ngu said that using mobile devices close to the body is also not good, not to mention that it is a hotbed of bacteria, making it easy for the body to become infected.
