General population eating persimmons will not cause blood sugar to rise, while patients with high blood sugar and diabetes can eat in moderation if their blood sugar control is up to standard, and cannot eat if their blood sugar control is not up to standard. The content of carbohydrates in each 100g persimmon is about 10%-14%, mainly containing sucrose, glucose and fructose, so it can be easily absorbed after eating and make blood sugar rise. I. General population General population eating persimmon blood sugar will not rise because insulin is secreted on demand.
