How can a person with diabetes eat watermelon; when it raises blood glucose? 

Like other fruits, watermelon contains carbohydrates. Carbohydrates then get digested and converted into sugar. The more carbohydrate you consume, the more rise in glucose will occur; in other words.

Carbohydrate consumption is directly proportional to sugar level.

So, a patient should keep an eye on his carbs intake.

Fruits have a high GI.

Scores are assigned to every food that ranges from 0-100.

High GI foods = score above 70

Medium GI foods = 56-69

Low GI foods = 1-55 

Watermelon has a high GI and won a 72 score, so it raises blood glucose levels quickly.

Ripe apples, mangoes, pineapples, and watermelon have a high GI. Here you will ask a question yourself.

Do You Know, What is GI?

This article is dedicated to helping you.

GI means how quickly a food raises the body’s glucose level.

The rise in glucose levels depends on portion sizes.

Serving size for the patient (Diabetics)

One serving size for a diabetic patient is one cup per day, which contains:

  • Calcium = 46g
  • Sugar = 9g
  • Fiber = 0.6g
  • Carbs = 12g 

How is the serving mentioned above size suitable for everyone?

A patient should check glucose level; after two hours of eating watermelon, it should not exceed 180mg/dl.

If the glucose level rises to 50 points after eating it, the person should decrease the portion size to half a cup.

Keep in mind

No doubt that watermelon contains natural sugar. Sugar is not solely responsible for raising your blood glucose level. Keep a proper check on the intake of carbohydrates.
