11 Low-Sugar Fruits

Why do low-sugar fruits matter?

Because with them, your homemade smoothie runs a much lower risk of turning into a sugar bomb or, in other words, truly deserves to be called a healthy smoothie.

Now that you know how much sugar some of your favorite fruits contain, you may also want to know whether it is actually possible to build an altogether low-sugar smoothie.

We have analyzed, deconstructed and rebuilt the DNA of a truly low-sugar smoothie for you, from the fruit and greens over the healthy fats and superfood spices down to the liquid base to include, all of it with as little sugar as possible. Check out our list of 9 truly low-sugar smoothies here.

One thing we can tell you for sure when it comes to cutting down on sugar in your smoothies is this: quantities and serving sizes make all the difference.

If you add 3-4 or more servings of fruit to one smoothie, even a low-sugar fruit might produce a sugary drink. 

So, it is important to enjoy fruits, even low-sugar fruits in moderation by keeping an eye on the number of servings you consume. In terms of overall daily fruit servings, the American Heart Association recommends 4 servings of fruit a day.

Keep in mind, that when it comes to dealing with the effects of sugar on your system, fiber is your friend. High-fiber fruits help slow down digestion, which means that your blood sugar may not spike as quickly. That way, fiber provides for more steady energy levels.

Finally, if you are serious about cutting back on sugar in your diet while optimizing for nutritional value, consume the fruit whole rather than extracting just its juice. The skin contains higher levels of fiber and makes you fuller, controlling how much you take in.

People with any health condition, including diabetes, may want to speak with their doctor or registered dietitian about the type and amounts of fruit to consume.
