Delicious Sugar-Free Smoothies You Need to Try

Delicious Sugar-Free Smoothies You Need to Try

Smoothies are a crowd-favorite treat that are a hit any time of year. They are customizable, refreshing, delicious, and can be easily incorporated into a healthy, balanced diet. Most people are tempted to just grab a pre-made smoothie while on the go, but those options tend to be loaded with added sugar, making them a less-than-healthy treat. 

Sugar-free smoothies are the right combination of delicious and healthy — a fun treat without the extra sugar. Here, you’ll learn about what sugar-free actually means, which fruits and veggies are best for smoothies, and some healthy, sugar-free smoothie recipes you can make in your Blendtec.

What Does Sugar-Free Actually Mean?

According to the Food and Drug Administration, a food must contain less than 0.5g of sugar per serving to be considered sugar-free. It is important to note that naturally occurring sugar and a small amount of added sugar are still acceptable for sugar-free claims. If a food contains artificial sweeteners or sugar alcohols, it cannot be considered sugar-free.

What You Need to Know About Fruit Sugars

All fruit contains two types of natural sugars: fructose and glucose. Both of these sugars have a different effect on the body: glucose raises the blood sugar, whereas fructose is broken down by the liver. Fruit sugars, when they come from whole fruits, are safe when consumed in moderation as part of a healthy, balanced diet.
