Is Coconut Water Good for Diabetes?

Coconut water can lower blood sugar and retinal damage caused by diabetes and acts as medicine or a nutrient in treating diabetes and its complications. [1]

Not much research on the effects of coconut water on diabetes is available there. 

However, several animal studies show that consumption of coconut water can improve glycemic levels. In a study, diabetes-inducing drug alloxan was injected into rates and given mature coconut water for forty-five (45) days. [2]

Blood glucose, hemoglobin A1C (HbA1c), and oxidative stress were significantly improved in coconut-treated rates compared to controls. [3]

The researchers link these findings to high levels of potassium, magnesium, manganese, vitamin C and L-arginine in coconut water, all of which help improve insulin sensitivity. [4]

So, coconut water in diabetes can help a patient. 

However, most of these studies used matured coconut water, which is much fatter than young coconut water. Therefore, it is not known whether ordinary coconut water can have the same effect. 

Although unsweetened coconut water is a natural sugar source, it is a better choice than other sweetened beverages and has little effect on blood sugar levels.

A study on rats showed that administration of coconut water inhibited the increase in total cholesterol (very-low-density lipoprotein and low-density lipoprotein), cholesterol and triglycerides but increased high-density lipoprotein. [8]

Tissue fat levels such as liver, heart, kidney, and aorta levels were significantly reduced in coconut water treated rates. [9]
