Have an early dinner. Eating dinner early is a good health care policy recommended by medical experts. Studies have shown that eating early at dinner can greatly reduce the incidence of urinary calculi. There is a lot of calcium in dinner food. In the process of metabolism, part of calcium is absorbed and utilized by the small intestine, and the other part is filtered into the urinary tract and excreted. The peak of calcium excretion is usually 4-5 hours after dinner. If you eat dinner too late, when the peak of calcium excretion comes, people fall asleep, which is easy to deposit and form small crystals. Over time, it gradually expands to form stones.
The elements to eat for dinner. Dinner must be vegetarian, mainly with carbohydrate-rich foods, especially some fresh vegetables, and try to reduce the intake of protein and fatty foods. However, in real life, due to the relatively sufficient preparation time, most family dinners are very rich, which is not conducive to health.
If protein is ingested too much, it will stay in the intestine if it cannot be absorbed by the human body, and it will deteriorate to produce toxic substances such as ammonia, indole and ammonia sulfide, which will stimulate the intestinal wall and induce cancer. If you eat too much fat, your blood lipids will rise. A large number of clinical medical studies have confirmed that the blood lipid of people who often eat vegetarian food for dinner is generally three to four times higher than that of people who often eat vegetarian food, while people with hyperlipidemia and hypertension will add fuel to the fire if they often eat vegetarian food for dinner.
Eat less for dinner. Eat less dinner than breakfast and Chinese food. It is generally required that the calories provided by dinner should not exceed 30% of the total calories in the whole day. Eating too many calories at dinner often leads to the increase of blood cholesterol, and too much cholesterol accumulates on the blood vessel wall, which will induce arteriosclerosis and cardiovascular and cerebrovascular diseases over time; If you eat too much at dinner, the concentration of sugar, amino acids and fatty acids in your blood will increase. After dinner, people tend to exercise less and consume less calories. These substances will be converted into fat under the action of insulin, and the body will gradually become obese after a long time.
Generally speaking, if the staple food is100g of flower rolls, steamed bread or rice, porridge or noodle soup, and the non-staple food is 50-100g of meat and poultry,100g of fish and some vegetables as dinner, the heat energy, food intake and nutrients can meet the needs of normal people. However, dinner should be less, not too absolute, and cannot be generalized. For those workers who work at night, students who burn the midnight oil, and people who do word work, they should not only have a full meal, but also add a snack appropriately. Drinking a glass of milk, eating some biscuits or eating an apple two hours after a meal can satisfy hunger, increase heat energy and maintain energy.
No dessert for dinner. It's best not to eat sweets for dinner. No matter how much you love sweets, we should try to reduce the intake of sweets for our health. Eating sweets at night will decompose white sugar into sugar and glucose, which will be directly converted into fat after being absorbed by the human body. Because exercise can inhibit transformation, why eating sweets before exercise will not gain weight. Eating sweets for dinner and sleeping without exercise at all will inevitably lead to obesity.
Avoid eating late at night. Health experts pointed out that eating midnight snack often is more harmful to health and easy to cause gastric cancer. If you often eat at night and the gastrointestinal tract is not rested, it is impossible to repair its mucosa smoothly. At the same time, when sleeping at night, food stays in the stomach for a long time, which will promote the secretion of gastric juice and stimulate the gastric mucosa. Over time, it is easy to lead to gastric mucosal erosion and ulcer, and the resistance is weakened. If food contains carcinogens, such as fried, grilled and waxed food, it is more likely to have adverse effects on gastric mucosa, which will lead to gastric cancer. Therefore, this bad eating habit should be overcome as soon as possible.
Overeating at dinner will swell the stomach and oppress the surrounding organs. After meals, the intense work of the stomach, intestine, liver, gallbladder, pancreas and other organs will send information to the brain, which will cause the brain to be active and spread to other parts of the cerebral cortex, causing insomnia.
