1, honey can't be boiled with boiling water or cooked at high temperature, because unreasonable heating will seriously destroy the nutrients in honey, inactivate the enzymes in honey, darken the color, volatilize the fragrance, change the taste and have an unpleasant sour taste. High temperature destroys the unique fragrance and taste of honey, which makes it volatilize, reduces the antibacterial effect and destroys the nutritional components. So honey is best diluted with warm water or cold water below 40℃. Especially in hot summer, drinking honey with cold water is a good cool and healthy drink. 2. The eating time of honey is very particular. Generally speaking, it is more appropriate to eat honey before meals 1- 1.5 hours or 2-3 hours after meals. However, for patients with gastrointestinal diseases, the eating time should be determined according to the condition, so as to play its medical role. If you eat honey one and a half hours before meals, it can inhibit the secretion of gastric acid; If you eat honey immediately after eating, it will stimulate gastric acid secretion; Warm honey solution can dilute gastric juice and reduce its acidity, while cold honey solution can increase the acidity of gastric juice and stimulate intestinal movement, so it can be used for diarrhea. Therefore, patients with hyperacidity or hypertrophic gastritis, especially those with gastric and duodenal ulcer soup, eat warm honey water 1.5 hours before meals, which can not only inhibit gastric acid secretion, but also reduce gastric acid, thus reducing the irritation to gastric mucosa and facilitating the healing of ulcer surface; Patients with gastric acid deficiency or atrophic gastritis should eat cold honey water immediately after eating. People with neurasthenia eat honey before going to bed every day, which can promote sleep, because honey has the function of calming the nerves, increasing wisdom and improving sleep.
