Couscous has gained popularity worldwide, often regarded as a staple in many Mediterranean and North African diets. This versatile grain-like substance can be used in salads, side dishes, and main courses. But for those mindful of their blood sugar levels, one essential question comes to mind: Is couscous a low GI (glycemic index) food? This article will unravel the complexities of couscous and its impact on blood sugar, exploring whether it can be a healthy addition to your diet.
What is Couscous?
Couscous is a type of pasta made from semolina flour, which is derived from durum wheat. While many people consider it a grain, it is technically a form of pasta due to its production process, in which durum wheat is moistened and rolled into tiny granules. Couscous is often found in three forms:
- Traditional Couscous: Steamed and fluffy, this is the most common type found in North African cuisine.
