If the abdomen is full, the diaphragm will move up, affecting the normal activities of the heart and lungs. In addition, more food needs to be digested, and a large amount of blood will be concentrated in the gastrointestinal tract to help, resulting in reduced blood supply to the heart and brain, which is easy to cause symptoms such as acute gastroenteritis, acute pancreatitis, angina pectoris and stroke.

Second, avoid drinking too much.

Drinking too much at night can easily lead to acute alcoholism, which will hurt the stomach, liver and brain.

Third, avoid fat, sweet and greasy.

Too much greasy food will stimulate intestinal mucosa, cause indigestion, affect the absorption of nutrients and aggravate the deposition of fat. Dinner should be light, which is beneficial to stomach, body fluid and sleep.

Fourth, avoid eating too salty.

Sodium in salt can lead to water retention in the body, increase the burden on the heart and kidneys, and cause high blood pressure, fatigue and stroke.

Five, avoid drinking strong tea.

Drinking too much tea will increase frequent urination and affect the quality of sleep. At the same time, tea contains a lot of caffeine, which is exciting and difficult to sleep. Tannic acid in tea can combine with protein in food to form a large amount of tannic acid protein, which makes people constipated. Moreover, drinking too much tea in a short time will suddenly increase the water in the body and increase the burden on the heart and kidneys of the elderly, which is even more harmful to the elderly who already have high blood pressure, heart disease and kidney disease.

Sixth, avoid eating raw.

Eating cold drinks and cold dishes will cause vasoconstriction of gastric mucosa and decrease the secretion of gastric juice, leading to loss of appetite and indigestion.

Seven, avoid eating fast.

Chew slowly to facilitate the digestion and absorption of nutrients.

Old people should not take eating as the only purpose of maintaining life and filling their stomachs. In fact, a correct and reasonable diet is the most valuable shortcut for the elderly to supplement and strengthen their health, and it is also the most beneficial and effective fitness method.
