Patients with diabetes and obesity should strictly control the amount of fruit they eat, while vegetables are relatively safe.

Compared with fruits, vegetables are alkaline foods that can more effectively adjust the balance of the internal environment, relieve fatigue, and excrete toxins. Fruits, due to their tannic acid content, have a weaker effect on regulating the internal environment of the human body.
