Fruit is sweet and nutritious, and almost everyone likes it. However, the knowledge of eating fruit lies not only in "the right medicine", but also in the time of eating. Some fruits are suitable for eating before meals, which can stimulate appetite; Some fruits are best eaten after meals, which can help the digestion and absorption of food; Some eat in the morning to refresh themselves; Eating at night can soothe nerves and help you sleep ... Let's see how to correctly grasp the "time difference" of eating fruit. Hawthorn should not be eaten in the morning. Hawthorn, whether it is fresh fruit or its products, has the effects of removing blood stasis, resolving phlegm and detoxifying, heatstroke prevention and cooling, and stimulating appetite. However, people with an empty stomach or weak spleen and stomach should not eat in the morning, and those with gastritis and hyperacidity should eat less. Eating grapefruit after breakfast is the first choice for pregnant women. The pulp contains natural folic acid, which is not only very important for early pregnancy, but also essential throughout pregnancy. Moreover, grapefruit is rich in pectin, which can reduce the content of low-density lipoprotein cholesterol, reduce the damage of arterial wall, maintain vascular function and prevent heart disease. However, due to its high acid content, it is best to use it after meals, especially after breakfast, which can quickly wake up the brain. Eating bananas and red dates before meals is high in potassium, which is beneficial to the function of the heart and muscles. At the same time, bananas can help treat constipation and diarrhea in children and are suitable for eating before meals. Jujube contains a lot of vitamin C, so it has the reputation of "natural vitamin C pill", and it is better to eat it before meals. But people with stomachache, bloating and indigestion should avoid eating it. Eating pineapple after a meal helps digestion. Fresh pineapple contains protease. If you eat on an empty stomach, the proteolytic enzymes of pineapple will damage the stomach wall, and a few people will also cause allergic reactions. So it should be eaten after meals, which can also help digestion. Persimmons are best eaten at night. Persimmon contains a lot of persimmon gum and tannin. If you eat on an empty stomach in the morning, stomach acid will react with them to form blood clots, which will seriously affect the digestive function. Suitable for eating after meals or at night.
