Russet Potatoes Overview

Russet potatoes are a starchy root vegetable commonly used for baking, mashing, and frying. They are very high in carbohydrates and have a high glycemic impact, especially when cooked without cooling. Russet potatoes are not keto-friendly and are generally not diabetic-friendly in standard portions. Lower-carb substitutes include cauliflower, turnips, or rutabaga (portion-aware).
