Biscuits have a glycemic index of between 55 and 70, making them a medium to high GI food. This means that consuming them can cause a relatively rapid rise in blood sugar levels, especially if they are made with white flour and sugar. Of course, the type of biscuit, its fiber content, and its ingredients play a significant role in changing the glycemic index.
What is the glycemic index of biscuits?
The glycemic index of most plain biscuits is around 60. Whole-wheat biscuits have a lower GI, and some sweet, processed biscuits can reach a GI of around 70.
What does the glycemic index of biscuits mean?
The glycemic index, or GI, is a measure of how quickly a food raises blood sugar. The higher the number, the faster it will raise blood sugar. Biscuits tend to raise blood sugar more quickly than high-fiber foods because they contain refined flour and sugar.
Glycemic index table for biscuits
| Consumption mode | Glycemic Index (GI) |
|---|---|
| Plain biscuits | 60 |
| Whole grain biscuits | 50 to 55 |
| Creamy and sweet biscuits | 65 to 70 |
| High-fiber diet biscuits | 45 to 50 |
What factors change the glycemic index of biscuits?
Cooking and preparation method
Longer baking times and higher temperatures can speed up the digestion of starch, which can increase the GI of the biscuit. Crispy biscuits tend to have a higher glycemic index.
Amount of processing and form of consumption
The more refined the flour, the higher the glycemic index. Biscuits made with wholemeal, oat, or high-fiber flours tend to have a gentler effect on blood sugar.
Combining biscuits with other foods
Eating crackers with protein, nuts, or dairy can slow the rise in blood sugar. For example, eating crackers with Greek yogurt or peanut butter is a better choice than eating them alone.
Are biscuits suitable for diabetics?
Biscuits are suitable for diabetics with caution. Plain, sweet varieties can quickly raise blood sugar, but whole-wheat or low-sugar biscuits are a better choice in controlled amounts. It is important to pay attention to the amount consumed.
Frequently Asked Questions About the Glycemic Index of Biscuits
Does baking increase the glycemic index of biscuits?
Yes, in many cases, high heat and further processing cause starch to digest faster and increase the GI.
What is the difference between glycemic index and glycemic load?
The glycemic index only shows how quickly blood sugar rises, but the glycemic load takes into account not only the speed but also the amount of carbohydrates consumed.
What is the best way to consume biscuits to control blood sugar?
Choosing whole-grain, low-sugar biscuits and consuming them with protein or healthy fat can reduce blood sugar fluctuations.
Final summary
The glycemic index of biscuits is usually in the medium to high range, and the type of ingredients plays a significant role in its level. If your goal is to control your blood sugar, it is best to consume high-fiber, low-sugar varieties in moderate amounts.
