When you eat, it will be the amount of carbohydrates in your meals that determines how much your blood sugar will go up.
Therefore, counting carbohydrates can help avoid large fluctuations in your blood sugar.
In this film I will review the principles of counting carbohydrates.
Anyone with diabetes can use this regardless of the type of medication you are getting to lower your blood sugar.
In order to count or assess the amount of carbohydrates in your food, it is necessary to know what kinds of food and drink contain carbohydrates.
Then you can calculate the amount of carbohydrates in the portion you eat or drink of the product in question.
There are several ways to do this.
For example, you can look at the nutritional labelling on the packaging of the product.
The content of carbohydrates measured in grams per 100 grammes of the product will appear there.
Sometimes it is for example also listed how many grams of carbohydrates there are in 1 roll or 1 slice of bread, and then you don't have to figure this out for yourself.
To figure out how many grammes of carbohydrates there are in your meal, weigh the parts of the meal that contain carbohydrates.
On the plate here, it is the rye bread that contains carbohydrates.
This rye bread contains 50 grammes of carbohydrate per 100 grammes.
Therefore, you start by finding out how much carbohydrate there is per gramme of rye bread.
To do this, divide the 50 grammes of carbohydrate by 100.
The result is that there is 0.5 grammes of carbohydrate in 1 gramme of rye bread.
My slice of rye bread weighs 40 grams, so now I have to multiply 0.5 by 40, which gives 20.
There are therefore 20 grams of carbohydrate in this slice of rye bread.
It may take a little getting used to when you suddenly have to look at declarations and maybe get out your calculator, but over time, this will definitely become routine for you.
