Are Cherries Safe for Diabetes?
Patient's Query
My cousin has diabetes and we both love cherries. Some people say cherries are good because they are a fruit, while others say they increase sugar levels.
Can a person with diabetes eat cherries? How much is safe? Are all cherries the same?”
Endocrinologist Answers

Yes, fresh cherries can be eaten by people with diabetes, but portion size is the key.

Cherries and blood sugar
Cherries contain natural sugar, but they also have water, fiber, and plant compounds. Because of this, cherries usually raise blood sugar more slowly compared with sweets, juices, or desserts.
Many glycemic index (GI) tables classify cherries as a low to moderate GI fruit. This means they generally cause a smaller sugar spike when eaten in reasonable amounts.
Portion size matters more than the fruit itself
Even healthy foods can raise blood sugar if eaten in large quantities.
A practical portion for most people with diabetes is:
- About half a cup of fresh cherries.
- Or one small handful.
Eating more than this at one time can still push sugars up.
Helpful tip: Eating cherries along with protein or fat (for example, nuts or curd) may reduce sudden sugar spikes.
Fresh cherries vs processed cherries
Not all cherries behave the same in the body.
- Fresh cherries: Usually acceptable in moderation.
- Cherries in syrup, candied cherries, or sugar-added dried cherries: These act more like sweets and can raise blood sugar quickly.
Simple rule: If cherries taste like dessert or candy, they should be treated like dessert.
Digestive effects to know
Cherries naturally contain compounds such as sorbitol, which can cause bloating, gas, or loose stools in some people, especially if eaten in large amounts. This is not dangerous, but it is a sign to reduce quantity.
Who should be extra careful
Extra caution is needed if:
- Blood sugars are currently poorly controlled.
- There are frequent sugar highs after meals.
- Insulin or sugar-lowering tablets that can cause low sugars are being adjusted.
In such cases, it is best to check post-meal sugars after eating cherries and adjust portions accordingly.
Simple takeaway
- Fresh cherries are not forbidden in diabetes.
- Moderation is the key.
- Processed or sugar-added cherries should be limited.
- What you eat matters, but how much you eat matters even more.
