Diabetics should try to avoid or strictly limit the following fruits due to their high sugar content or high glycemic index.
Watermelon: Has a high glycemic index. Although it contains plenty of water, its sugar is concentrated and can easily cause a sharp rise in blood sugar.
Lychees and longans: Extremely high in sugar, and easy to overeat, which may lead to a rapid increase in blood glucose.
Mangoes and bananas: Sugar content increases when fully ripe, with a significant blood sugar-raising effect; bananas in particular are high in carbohydrates.
Grapes and jujubes (red dates): Dense in sugar; even a small amount provides a large sugar intake, so they are not suitable for frequent consumption.
Processed fruit products: Such as dried fruits and canned fruits, which usually contain added sugar and have a much higher glycemic index than fresh fruits.
Of course, the above are only some of the fruits that diabetics should try to avoid or strictly limit. Since fruit varieties vary by country and region, it is impossible to list them all. When choosing fruits, you can select local fruits based on their sugar content and glycemic index.
In addition, even when eating fruits with low sugar content or low glycemic index, diabetics should note that fruit should be avoided when blood sugar is not well-controlled.
