What is the nutritional benefit of substituting mashed potatoes with mashed turnips or rutabaga for metabolic management?
Answer
It significantly lowers the overall glycemic load of the meal.
Turnips are favorable for individuals monitoring blood sugar because they are relatively low in carbohydrates and calories, and high in fiber. When used as a substitute for starches like potatoes in mashed preparations, the high fiber content of the turnip slows down the rate at which any remaining sugars are absorbed into the bloodstream. This slowing effect prevents the sharp post-meal spikes in glucose levels typically associated with high-glycemic index foods, thereby lowering the overall glycemic load of the entire meal.
