The sugar content in plums is not very high, about 100 grams of pulp contains 8.8 grams of sugar, it is generally recommended to eat 3-4 plums per day. Plums are flat, sweet and sour, so eating them in large quantities can stimulate excessive secretion of stomach acid and affect the function of the gastrointestinal tract, so patients with poor spleen and stomach function should try to reduce their consumption. Plums contain more dietary fiber, carbohydrates, carotenoids, vitamins, and trace elements and other nutrients, so moderate consumption is beneficial for patients with unfavorable urination, dry mouth and throat, indigestion, and cirrhotic ascites. However, excessive consumption of plums can lead to damage to the spleen, stomach and teeth, and even patients without the disease should strictly control the amount of plums consumed. Fruits with high sugar levels include dates, coconuts, passion fruit, mangoes, pears, lychees, watermelon, and carrots, etc. Diabetics and people on a diet should consume the above fruits in limited quantities. The sugar content of plums is moderate, except for patients who are allergic to plums, there is generally no need to absolutely contraindicate the diet, but there may be toxic ingredients in plums that have a bitter, astringent taste, and patients need to refrain from eating them.
