Monk fruit and stevia are nonnutritive sweeteners. This means they have little-to-no calories or nutrients. Both are marketed as natural alternatives to sugar. This is true to a point. Monk fruit is typically not as refined as stevia, but may contain other ingredients. The stevia you buy in the grocery store is vastly different from the stevia you grow in your backyard. Even so, stevia and monk fruit sweeteners are more natural choices than artificial sweeteners containing aspartame, saccharine, and other synthetic ingredients. If you’re diabetic or trying to lose weight, read monk fruit or stevia product labels carefully to see if higher-calorie and higher-glycemic sweeteners were added. In the end, it all comes down to taste. If you don’t like the taste of monk fruit or stevia, their pros and cons don’t matter. If possible, try them both to see which you prefer.
