Watermelon Glycemic Index

Food that can be consumed by diabetics should have a glycemic index (GI) of not more than 50 units. Food with a GI of more than 70 is unacceptable, because it leads to a sharp increase in blood glucose, can cause hyperglycemia and exacerbate the disease. The average level of glycemic load is from 11 to 20 units of carbohydrates, and low is less than 10. The possibility of consuming watermelon depends on its calorie content and glycemic load. It’s important for diabetics not to exceed the amount of 200 g per day.

Watermelon has the following indicators:

  • glycemic index – 75 units;
  • glycemic load per 100 g of product – 4 g of carbohydrates;
  • calories – 38 kcal per 100 g.

The bread index is an indicator of how much sugar will be in the blood after consumption of carbohydrate-containing foods. As a measure, a piece of bread with a thickness of one centimeter and a weight of 20 g was selected. The body will spend 2 bread units of insulin to process such a slice without increasing the sugar level. The daily index has the following meanings:

  • for those with physical activity – 25;
  • with sedentary work – 20;
  • with diabetes – 15;
  • with obesity – 10.

Effect on the body

Sugar in watermelon is represented by fructose, which prevails over glucose and sucrose. In the berry it is more than other carbohydrates. It is important to note that fructose is far from harmless for diabetics, it can cause obesity if the norm is increased. At 40 g per day, fructose is very useful and easily absorbed by the body. Such a quantity will require a small dose of insulin, so you should not expect dangerous consequences.
