Busting the myths: rye flour’s true glycemic index revealed
What To Know
- The GI of a food is determined by comparing its effect on blood sugar levels to that of pure glucose, which has a GI of 100.
- Foods with a GI of 55 or below are considered low GI, while those with a GI of 70 or above are considered high GI.
- The GI of rye flour varies depending on the type of rye used, the milling process, and the presence of other ingredients.
The glycemic index (GI) is a measure of how quickly a carbohydrate-containing food raises blood sugar levels. Foods with a low GI release glucose slowly and steadily, while high-GI foods cause a rapid spike in blood sugar.
