FAQ
Frequently asked questions about glycemic index guide.
What does the glycemic index measure?
The glycemic index measures how quickly a food raises blood sugar compared with pure glucose. Lower GI foods generally cause a slower, steadier rise in blood sugar, which can help with energy stability and diabetes management.
How is glycemic load different from GI?
Glycemic load combines the GI value with the amount of carbohydrate in a serving. It gives a more practical estimate of a food's real-world impact because portion size matters, not just the GI number alone.
Which foods are considered low GI?
Most non-starchy vegetables, legumes, many whole grains, nuts, and some fruits are low GI. Foods with more fiber, protein, or fat tend to digest more slowly and usually score lower.
Why can GI values vary?
GI values are estimates and can change based on ripeness, cooking method, processing, and how the food is eaten. Combining foods with protein, fat, or fiber can also lower the overall blood sugar response.
Is a low GI food always healthy?
Not always. GI only measures blood sugar response, not overall nutrition. For example, some highly processed foods may have a lower GI but still be low in nutrients, so it's best to consider the full nutrition profile.
