A good eating habit is very important for good health.Habits determine health. If you want to be healthy and work efficiently, please stay away from bad eating habits. Eating habits refer to people's preferences for food and drink.These include preferences for food ingredients, cooking methods, and cooking flavors and condiments.Eating habits are an important element in food culture.The eating habits of people all over the world are very diverse due to the various influences of regions, products, and cultural history. We all know that to sustain life, we need to eat.As the saying goes, habits determine health. If you want to be healthy and work efficiently, please stay away from bad eating habits.

(1) Eat too little. Some people go on a diet for weight loss.People who eat less, especially those who skip breakfast, are prone to fatigue and sleepiness.Students who need to go to school in the morning or salaried workers who are limited by working hours often skip breakfast.Not eating once or twice becomes a habit over time. However, nutritional studies have proven that breakfast is the most important meal of the day.Breakfast is the "switch" that activates the brain.After a night of sound sleep, the secretion of hormones enters a trough, and the stored glucose is exhausted 8 hours after a meal, and the cells of the human brain can only obtain energy from the nutrient glucose.Breakfast, such as timely rain, can make hormone secretion quickly enter a climax and provide energy for brain cells.

If you eat less breakfast, it will make you depressed and reduce work efficiency.After a long time, it will make people tired, dizzy, emotionally unstable, and even nausea, vomiting, fainting, etc., making it impossible to study and work energetically. (2) Overeating. After a large amount of food is eaten, the gastrointestinal tract has to increase blood supply in order to complete the task of digestion and absorption, so that a large amount of blood flows to the digestive tract, and the blood supply to peripheral tissues and the brain will decrease accordingly, especially the brain, which cannot store energy. Oxygen, energy metabolism will be hindered, directly affecting the normal performance of brain function, making people feel sleepy.

Recent research data also shows that if you eat too much for a long time, it can accelerate cerebral arteriosclerosis and easily cause senile dementia.For this reason, relevant experts remind everyone that no matter men, women, old or young, their diet should not be too full, especially the elderly should be 70% full. (3) Overeating greasy food. Occasionally consuming too much fat is not harmful to the body, but if a patient with hyperlipidemia consumes too much fat, it will make the blood lipids that have exceeded the standard higher.At this time, people are not only prone to sleepiness, but also a little strenuous activity will increase the load on the heart and aggravate fatigue.

(4) Overeating seafood. Seafood food contains a substance called sodium glutamate, which is the main chemical component of monosodium glutamate. It can decompose glutamic acid during digestion. After sodium glutamate enters the human body, it can be converted into δ-aminobutyric acid. δ-Aminobutyric acid is an inhibitory neurotransmitter, and its production is insufficient, which can easily cause excessive excitement of the central nervous system, such as mania or convulsions.But producing too much will have an inhibitory effect on the central nervous system, making people drowsy. (5) Excessive intake of tryptophan-containing foods.

Tryptophan is an essential amino acid for the human body, which can promote the secretion of serotonin from brain nerve cells.Serotonin has the function of inhibiting the thinking activity of the brain.Therefore, people who consume a diet rich in tryptophan are prone to fatigue and drowsiness.Foods rich in tryptophan include millet, milk, shiitake mushrooms, sunflower seeds, black sesame, soybeans, pumpkin seeds, meat floss, fried tofu, eggs, etc. (6) Drink a lot of acidic beverages after exercise. After strenuous or large-scale exercise, the body will accumulate more lactic acid. Drinking a lot of acidic drinks at this time will cause the accumulation of acidic metabolites in the body, which will aggravate the feeling of fatigue.At this time, the reasonable method is to eat more light and digestible foods, preferably alkaline foods such as vegetables and fruits.

Icelandic residents eat smoked mutton and smoked salmon all year round, and more than 50% of the cancer deaths in the population are gastric cancer patients.Data show that eating too hot food can cause hyperemia and damage to the oral mucosa, resulting in ulcers. Rough food and eating too fast can cause mechanical irritation to the esophageal mucosa. These may be one of the causes of esophageal cancer. The intake of aflatoxin-contaminated food is related to the occurrence of liver cancer. The warm and humid climate in Southeast Asia provides conditions for food mildew, so the incidence of liver cancer is higher. People who eat greasy food, milk and other high-fat diets for a long time will cause Increased blood lipids in the body increase bile secretion, resulting in high saturation of cholesterol in bile and easy formation of gallstones; eating too much sweets will increase insulin secretion in the body, promote the formation and accumulation of cholesterol, and thus easily form gallstones; often do not eat Breakfast, fasting for too long, can lead to reduced bile secretion, reduced bile acid content, the formation of high-cholesterol bile and the formation of stones.Therefore, patients with gallstones should start from adjusting their diet to prevent gallstones.

With the rapid development of social economy in the United States, great changes have taken place in people's dietary structure and eating habits. The proportion of grains, beans and potatoes in the dietary structure has dropped significantly, and the intake of animals and oils has increased accordingly. Excessive consumption of pork, beef, and mutton can increase the risk of colon cancer and kidney cancer; excessive intake of animal fat and protein can increase the incidence of endometrial cancer and ovarian cancer; Processed foods such as dried, sun-dried, and fried foods are closely related to the occurrence of cancers in the oropharynx, esophagus, stomach, pancreas, nasal cavity, and throat of the digestive tract.
