Is Coconut Water Good For Diabetes?


  • Coconut water is good for hydration and is a great source of electrolytes.
  • It is naturally low in calories and contains sugar along with some minerals.
  • Coconut water has a moderate glycemic index (GI) which means it can moderately increase blood sugar levels.
  • There is not enough research that concludes whether coconut water is good for diabetes.

Coconut water, the clear liquid found inside young green coconuts, has gained popularity in recent years as a natural and refreshing beverage. It is a low-calorie beverage containing natural sugars. It helps restore electrolytes after exercise and prevents dehydration.

Coconut water calories

One glass (240 mL) of coconut water contains 36 kcal with 84% carbs, 7% protein, and 9.4% fat. It is a good source of potassium, vitamin B5, vitamin B6, vitamin E, magnesium, and an excellent source of manganese.

Glycemic index of coconut water

The glycemic index (GI) is a measure of how quickly a food raises blood sugar levels. Foods with a high GI rating are more likely to cause a rapid increase in blood sugar, while foods with a low GI rating are less likely to cause a rapid increase.

It's also worth noting that coconut water is not a low-glycemic beverage. Coconut water has a GI rating of around 55, which is considered moderate1.

Health benefits of coconut water

Coconut water is a good electrolyte, high in antioxidants which hydrates the body, lowers blood pressure and provides energy during workout.

Coconut water is great for hydrating your body. It is often advertised as a healthy alternative to sugary sports drinks.

It might not only provide enough energy during a workout, but it can help with rehydration afterward.

Research on animals has shown that coconut water contains antioxidants that may help modify free radicals so they no longer cause harm2.

Free radicals are a type of unstable reactive oxygen species. These free radicals can build up in cells and cause damage to other molecules like DNA, lipids, and proteins.

All the health benefits of coconut water mentioned above concerning hydration and reduction of oxidative stress do not conclude whether coconut water is good for diabetes.

Let's take a closer look at what research suggests.

Coconut Water and Diabetes

There are two independent animal research studies conducted to determine the effect of coconut water on diabetes. No human studies to support testing this hypothesis were found to date.

A study conducted on diabetic rats indicates that the diabetic rats treated with coconut water had decreased blood glucose levels and reduced oxidative stress3.

However, this study was conducted on rats with matured coconut water (MCW) and the nutritional composition of matured coconut water could be significantly different from tender coconut water.

In a second study on diabetic rats4, it was reported that coconut water can effectively reduce blood glucose in diabetic rats, but its mechanism remains unknown and requires further experimental studies.

Even though these animal studies on coconut water and diabetes demonstrated encouraging results, it is not sufficient to conclude that coconut water is good for sugar patients.

More comprehensive human studies are required to support this hypothesis.

Based on the sugar composition and moderate glycemic index of coconut water, we do not recommend regular consumption of coconut water for diabetic patients.

Coconut water has a GI rating of around 55, which is considered moderate. This means that it is likely to cause a moderate increase in blood sugar levels, which may not be suitable for individuals with diabetes.

In addition, some brands of packaged coconut water may contain added sugars or other sweeteners, so it's important to check the label before purchasing.

Considering the high mineral content and hydration properties of coconut water, diabetic patients can drink not more than 1 glass (240 mL) of unsweetened tender coconut water post workouts to restore electrolytes lost during exercise.

However, despite its potential benefits, it's important to remember that coconut water should not be used as part of diabetes treatment.

Managing diabetes requires a combination of lifestyle changes, such as eating a healthy diet, getting regular exercise, and taking medications as prescribed.

In conclusion, while there is some limited evidence to suggest that coconut water may have potential benefits for individuals with diabetes, more research is needed to determine its effectiveness.

Additionally, coconut water is not a low-glycemic beverage and should not be relied upon as a sole method of managing Diabetes.

While incorporating coconut water into your diet as a post-workout may have some potential benefits, it's important to remember that managing diabetes requires a combination of lifestyle changes and medications.
