Can Diabetics Eat Fruits?
Diabetes is a common disease among middle-aged and elderly people, and if uncontrolled, it may lead to complications. Treatment typically combines diet, exercise, and medication, with dietary therapy serving as the foundation of all approaches. For mild diabetes, dietary therapy alone may suffice to control the condition.
The basic principle of dietary therapy is to estimate the required total caloric intake based on the patient's weight and activity level, and to reasonably plan daily meals. Foods high in sugar should be avoided, and those high in fat and starch should be eaten sparingly. The diet should primarily consist of vegetables and whole grains, supplemented with a certain amount of high-quality protein sources such as lean meat, milk, eggs, and soy products. Since fruits contain sugar, can diabetics eat them?
Completely avoiding fruits is impractical, as they are rich in vitamins, fiber, and minerals—beneficial nutrients for diabetics. Fruits contain glucose, fructose, and sucrose. Fructose does not require insulin for metabolism, so diabetics whose blood sugar is under control do not need to completely avoid fruits.
Moreover, sugar content varies significantly among fruits, so they cannot be treated equally. Fruits with less than 10 grams of sugar per 100 grams include green plums, watermelon, honeydew melon, coconut milk, oranges, lemons, grapes, peaches, plums, apricots, loquats, pineapples, strawberries, sugarcane, coconuts, cherries, olives, etc.—these can be selected by diabetics. Fruits with 11–20 grams of sugar per 100 grams include bananas, pomegranates, pomelos, tangerines, apples, pears, lychees, mangoes—these should be consumed cautiously. Fruits exceeding 20 grams include jujubes, red fruits, especially dried jujubes, honeyed jujubes, persimmon cakes, raisins, dried apricots, longans—these have very high sugar content and should be strictly avoided.
Many vegetables can serve as fruits, such as tomatoes, cucumbers, and gourds. With less than 5 grams of sugar per 100 grams and rich in vitamins, they can fully substitute for fruits and are suitable for diabetic patients—this practice should be widely promoted.
In addition, portion size must be adjusted flexibly—not rigidly fixed. Watermelon contains 4% sugar, pear 12%, banana 20%. Although watermelon has low sugar content, eating 500 grams is equivalent to consuming 100 grams of banana or 170 grams of pear, so portion sizes must not be excessive. The way fruits are eaten also matters: avoid eating immediately after meals. Instead, consume between meals or before bedtime. It is best to try gradually—test urine sugar levels two hours after eating. If urine sugar increases, reduce the amount; if urine sugar remains high even after reducing fruit intake, appropriately decrease staple food consumption.
