The glycemic index in 30 seconds
The glycemic index ranks carbohydrate foods by how fast they raise blood sugar, compared with pure glucose at 100. Low GI is 55 or less, medium is 56–69, and high is 70 or more.
Glycemic load adds portion size: watermelon has a high GI (76) but a GL of only 5 per slice.
Small swaps add up: sourdough for white bread, basmati for jasmine rice, rolled oats for cornflakes.
Why the glycemic index matters
Two foods with the same amount of carbohydrate can affect your blood sugar very differently. High-GI foods are digested quickly and cause a sharp rise, often followed by a dip that leaves you hungry again. Low-GI foods are digested slowly, so blood sugar rises gently and stays steadier. Choosing lower-GI versions of the foods you already eat is one of the simplest ways to even out your energy through the day.
Six swaps that make the biggest difference
| Instead of | Try | GI |
|---|---|---|
| White bread | Sourdough or pumpernickel | 75 → 50–54 |
| Jasmine rice | Basmati or parboiled rice | 89 → 38–58 |
| Instant oatmeal | Rolled or steel-cut oats | 79 → 52–55 |
| Cornflakes | Original All-Bran | 81 → 44 |
| Baked russet potato | Boiled new potatoes | 85 → 57 |
| Soft-cooked pasta | Pasta cooked al dente | 49 → 38 |

Frequently asked questions
What is a low glycemic index food?
A food with a GI of 55 or less. Lentils, chickpeas, most fruit, rolled oats, sourdough, and pasta cooked al dente are all in the low range. See the full low GI food list.
Which matters more, glycemic index or glycemic load?
Use both. GI tells you how fast a food’s carbs act; glycemic load adjusts for how much you eat. Watermelon has a high GI but a low GL per slice, while a big plate of pasta has a low GI but a high GL. More in glycemic load vs. glycemic index.
Do meat, eggs, and vegetables have a GI?
Most don’t. Meat, fish, eggs, oils, and non-starchy vegetables contain so little carbohydrate that a GI can’t be measured, which makes them the easiest foods to build a low-GI meal around.
Can these lists help with diabetes?
They can help you understand how different foods affect blood sugar, and our diabetes-friendly food list and blood sugar chart are good starting points. Your own meal plan and targets should come from your doctor or dietitian.
