Diabetes is a chronic condition that affects millions of people worldwide. It is characterized by high blood sugar levels due to the body’s inability to produce or use insulin effectively. The management of diabetes involves maintaining a healthy diet and lifestyle, and cherries have been touted as a potential addition to a diabetes-friendly diet. In this article, we will explore the potential benefits of cherries for diabetes, backed by scientific evidence.


What are Cherries?

Cherries are a type of fruit that belongs to the genus Prunus. They are known for their sweet and tart flavor and come in different varieties, including sweet cherries (Prunus avium) and sour cherries (Prunus cerasus). Cherries are rich in nutrients such as vitamins A and C, potassium, fiber, and antioxidants. They are also low in calories and can be enjoyed fresh or dried, in smoothies, salads, or as a snack.

Cherries and Blood Sugar Control

One of the most significant concerns for people with diabetes is managing their blood sugar levels. High blood sugar levels can lead to various complications, including nerve damage, kidney disease, and cardiovascular disease. Several studies have explored the potential of cherries to help control blood sugar levels.

A study published in the Journal of Agricultural and Food Chemistry found that consuming sweet cherries led to a significant decrease in blood sugar levels in both healthy and diabetic participants. The study also found that sweet cherries had a lower glycemic index (GI) than other fruits, meaning they are less likely to cause a spike in blood sugar levels.

Another study published in the British Journal of Nutrition found that consuming tart cherries reduced insulin resistance in participants with metabolic syndrome. Insulin resistance is a common precursor to type 2 diabetes and occurs when the body’s cells become less responsive to insulin. The study suggests that tart cherries may improve insulin sensitivity, which could help prevent or manage diabetes.

Anti-inflammatory and Antioxidant Properties of Cherries

Cherries are also known for their anti-inflammatory and antioxidant properties, which may benefit people with diabetes. Chronic inflammation is a common characteristic of diabetes and is associated with insulin resistance and other complications. Antioxidants help neutralize harmful free radicals in the body, which can contribute to inflammation and damage to cells.

A study published in the Journal of Medicinal Food found that tart cherry juice reduced inflammation in healthy women. The study also found that the cherry juice improved antioxidant activity in the participants’ blood, suggesting that cherries may help reduce inflammation and oxidative stress in the body.

Cherries and Heart Health

People with diabetes are at a higher risk of developing heart disease, making heart health an essential aspect of diabetes management. Cherries may have a positive impact on heart health due to their high levels of antioxidants and anti-inflammatory compounds.

A study published in the American Journal of Clinical Nutrition found that consuming sweet cherries reduced risk factors for heart disease, including high blood pressure and cholesterol levels. The study also found that sweet cherries improved antioxidant capacity and reduced inflammation in the participants’ blood.

Another study published in the Journal of Functional Foods found that consuming tart cherry juice improved markers of cardiovascular disease in older adults. The study found that tart cherry juice reduced blood pressure and total cholesterol levels, suggesting that cherries may have a beneficial effect on heart health.

Incorporating Cherries into a Diabetes-Friendly Diet

Cherries can be a nutritious addition to a diabetes-friendly diet. They are low in calories and carbohydrates, making them an excellent snack option. Dried cherries may contain added sugar, so it is important to check the label and choose unsweetened varieties.

Fresh cherries can be incorporated into meals in various ways, such as adding them to a salad, mixing them into a smoothie, or using them as a topping for oatmeal or yogurt. Cherries can also be used in recipes for baked goods or desserts, but it is important to consider the overall carbohydrate and sugar content of the dish.

It is worth noting that while cherries have potential benefits for people with diabetes, they should not be seen as a substitute for other aspects of diabetes management. Maintaining a healthy diet and lifestyle, taking medications as prescribed, and monitoring blood sugar levels regularly are all essential for managing diabetes effectively.

Potential Risks and Precautions

While cherries are generally safe to consume for most people, there are some precautions to consider, particularly for those with specific health conditions. For example, cherries contain high levels of potassium, which can be a concern for people with kidney disease or those taking certain medications that affect potassium levels. It is important to speak with a healthcare provider to determine the appropriate amount of cherries or cherry products to consume based on individual health needs.

Additionally, some people may experience an allergic reaction to cherries, which can range from mild symptoms such as itching or hives to severe reactions such as difficulty breathing or anaphylaxis. It is important to be aware of any potential food allergies and seek medical attention immediately if an allergic reaction occurs.


Cherries are a nutritious fruit that may have potential benefits for people with diabetes. The anti-inflammatory and antioxidant properties of cherries may help reduce the risk of complications associated with diabetes, while the potential blood sugar-lowering effects may help manage blood sugar levels. Cherries can be incorporated into a diabetes-friendly diet as a healthy snack or as an ingredient in various meals and recipes. However, it is important to consider individual health needs and any potential risks or precautions when consuming cherries or cherry products. As always, it is recommended to speak with a healthcare provider before making any significant changes to a diabetes management plan.
