Eat a meal.

(1) First of all, keep a happy mood when eating, which is conducive to the normal secretion of gastric acid. In a bad mood, gastric acid secretion will increase or decrease, leading to overeating or loss of appetite. Long-term unhappiness is one of the causes of digestive tract diseases such as gastritis.

(2) After eating, it is best not to smoke. Because smoke contains alkaloids or nicotine and other substances harmful to human body, after being absorbed by human body, it will cause the increase of bile secretion in the body, leading to bile gastritis and other diseases. After the increase of bile in the body, it may also inhibit the secretion of pancreatic juice by the pancreas and affect the digestion and absorption of food by the gastrointestinal tract.

(3) Maybe you will find that parents in their sixties and seventies eat everything, while themselves are more or less partial to food, which is actually related to their living standards. In the past, the living conditions were poor, so it would be nice to have enough to eat. Who still insists on whether food is their favorite? But now it's different. Most families are at a well-off level.

(4) Many people will choose their favorite food, and they will definitely not eat what they don't like. In fact, this will lead to long-term lack of nutrition. For example, if you only like meat and don't like vegetables and fruits, you will lack dietary fiber in your body, and constipation is common. People who don't like meat will lack high-quality protein and iron in their bodies, which will affect their health.
