The carbohydrate content of a Granny Smith apple is a key nutritional characteristic. These carbohydrates primarily exist as natural sugars (fructose, glucose, and sucrose) and dietary fiber. A medium-sized Granny Smith apple typically contains approximately 20-25 grams of total carbohydrates, a significant portion of which is fiber, around 4-5 grams. This fiber contributes to feelings of fullness and aids in digestive health.
Understanding the carbohydrate profile of this popular fruit is important for individuals managing their blood sugar levels, such as those with diabetes, or those following specific dietary plans like low-carb or ketogenic diets. The balance between natural sugars and fiber in the apple contributes to its relatively low glycemic index, meaning it causes a slower and more gradual rise in blood sugar compared to foods with a high glycemic index. Additionally, apples have been a staple in human diets for centuries, valued not only for their taste but also for their nutritional properties, including the energy provided by the carbohydrate content.
