Coffee, honey and yogurt should not be drunk on an empty stomach.

Coffee

Coffee is a familiar drink for white-collar workers who travel around office buildings-coffee shops are the preferred place for daily business meetings, and coffee is also a refreshing tool for staying up late. Coffee contains caffeine, after entering the body will promote sympathetic excitement, thus eliminating drowsiness, improve blood circulation, the body also feels warm, do not feel tired, so there is a "refreshing" effect.

However, when the sympathetic nerve is stimulated and excited, it has a negative effect on appetite, that is, appetite will be reduced, so drinking coffee before a meal will not want to eat. In addition, due to the stimulation of the stomach and the increase of gastric juice secretion, stimulating the empty stomach is disadvantageous to patients such as gastric ulcers. But drinking after a meal is helpful to digestion because the secretion of gastric juice will increase. Therefore, there is absolutely no problem with drinking after a meal. Of course, as the saying goes, "going too far is not as good as it is". No matter how good it is, we have to "enough is enough". In principle, it is appropriate to drink two to three cups of coffee a day. If you drink four or five cups, most people will feel sick, so be careful.

Honey

Honey is a kind of nutritious natural nourishing food, and it is also one of the most commonly used tonics. Contains a variety of inorganic salts and vitamins similar to the concentration of human serum, which is easy for human body to absorb. Many white-collar workers have the habit of drinking honey water, which can prevent constipation, nourish the skin and keep the body healthy.

Experts remind: the consumption time of honey is very fastidious, it is recommended to drink 1.5-2 hours after meals. Drinking honey water on an empty stomach is easy to increase the acidity of the body, and over a long time, you will have too much gastric acid and get gastric ulcer or duodenal ulcer. If you have a bad stomach, it is best to drink with a 30-degree bubble, otherwise it is easy to cause diarrhea, gastroenteritis and other adverse symptoms. But the temperature should not be too high, from a pharmacological point of view, honey heated to more than 67 degrees, will destroy the vitamin, and reduce its aroma, nutritional value will be reduced.

Yoghurt

People often discuss how to drink yogurt is more beneficial to health, or when to drink yogurt is more conducive to nutrition absorption. If you drink yogurt on an empty stomach, it is easy to stimulate gastrointestinal emptying, and the nutrients in the yogurt will be excreted before thorough digestion and absorption. Drinking after meals can reduce irritation and allow yogurt to be slowly absorbed in the stomach.

Nutrition expert Li Guangyi said: generally speaking, it is best to drink yogurt between 30 minutes and 2 hours after a meal. Under normal conditions, the PH value of gastric juice is between 1 and 3; when fasting, gastric juice is acidic and the PH value is less than 2, which is not suitable for the growth of active lactic acid bacteria in yogurt. Only when the PH value of the stomach is relatively high, can the lactic acid bacteria in the yogurt grow fully, which is beneficial to health. In addition, the best temperature to drink yogurt is 10 ℃-12 ℃, pay attention to yogurt temperature should not exceed 50 ℃, otherwise it will make the beneficial bacteria inactive.
