Lettuce, Raw: A Low-Glycemic Leafy Green

Lettuce is one of the most commonly consumed leafy greens worldwide, serving as a base for countless salads and a crisp addition to sandwiches. But beyond its culinary versatility, raw lettuce offers impressive nutritional benefits while maintaining a low impact on blood sugar levels.

Glycemic Index and Glycemic Load

Raw lettuce has a Glycemic Index (GI) of 32, placing it firmly in the low-glycemic category. Foods with a GI below 55 are considered low-glycemic and cause a slower, more gradual rise in blood sugar levels compared to high-GI foods.

Even more impressive is lettuce’s Glycemic Load (GL) of just 0.76. Glycemic Load takes into account both the quality (GI) and quantity of carbohydrates in a food, providing a more accurate picture of how a food affects blood sugar. A GL under 10 is considered low, making lettuce an excellent choice for those monitoring blood glucose levels.
