People with diabetes should choose the best time to eat fruits, usually between 3 pm and 4 pm, and should exercise moderately after eating. The sugar content of different kinds of fruits is also different, and the sugar content of watermelons, apples, pears, oranges and kiwifruits is low. Banana, jujube, litchi and red fruit have higher sugar content; Although cherry tomatoes are shaped like tomatoes, their sugar content is high.
