Turbinado sugar is a less processed option than white sugar that retains small amounts of molasses. However, it does not contribute significant nutritional value and is rather expensive. Though it can be a flavorful ingredient, sweetener, or topping, it's best used in moderation  like all types of sugar.

Outside of pure stevia, I recommend using either raw honey or pure maple syrup. These sugars are not processed and they contain trace amounts of vitamins and minerals. At the end of the day, it is important to understand what sugar is doing to your body.
