Once upon a time, we had limited options for sweeteners. There was sugar, of course, and usually a couple of pastel-colored packets of artificial sweeteners. Now, alongside those old-school choices, you’ll often find more natural sugar substitutes and alternative sweeteners, from agave nectar and coconut sugar to stevia and luo han guo.
Otherwise known as monk fruit, luo han guo is a sweetener that comes from an Asian fruit. Here’s what you need to know about luo han guo.
What is luo han guo?
Luo han guo is commonly known as monk fruit. It’s most likely named after the Buddhist monks who grew the sweet fruit in Southeast Asia centuries ago.
In summer, you might sip a monk fruit beverage to beat the heat and quench thirst. It’s also consumed hot as a soothing beverage.
What are the benefits of luo han guo?
Let’s take a look at a few of the perks of this sugar substitute.
1. It comes from fruit.
While luo han guo sweetener needs to be processed, it starts with monk fruit.
2. It’s a zero-calorie sweetener.
“Luo han guo is a non-nutritive sweetener,” explains Cary Kreutzer, EdD, MPH, RDN, FAND, an associate clinical professor at the University of Southern California Leonard Davis School of Gerontology and USC Keck School of Medicine.
That means it doesn’t provide nutrients — like carbs, fat, protein, as well as micronutrients — but gives you a sweet flavor.
3. It’s much, much sweeter than sugar.
Luo han guo is 100 to 250 times sweeter than granulated sugar, so a little goes a long way. It’s not the sweetest sweetener, though. By comparison, sucralose is 600 times sweeter than sugar, while saccharin is 200 to 700 times sweeter!
What are the cons of using luo han guo (monk fruit)?
There are a few items to consider with this zero-calorie sweetener.
1. It’s not a “whole food.”
While the monks plucked the fruit from the trees and crushed them by hand to sweeten foods, luo han guo sweeteners are extracted via processing, explains Kreutzer.
2. It doesn’t taste exactly like sugar.
Luo han guo does come close, though. A 2018 study in the Journal of Dairy Science compared two sugar-free, and five reduced-sugar blends in vanilla protein shakes. Of the sugar-free options, a combination of monk fruit (and stevia) tasted the most like the control shake made with sugar.
At first, and if you have sensitive taste buds, you may note bitter or metallic flavors in alternative sweeteners, including luo han guo.
3. It should be consumed in moderation.
Kreutzer warns against leaning too heavily on any sugar substitute.
“They’re an easier way to make things taste sweeter,” she says. “However, we are perpetuating this notion that everything needs to taste sweet.”
How to use luo han guo?
Since luo han guo is sweeter than sugar, start with a fraction of what you’d typically use.
If you’re using a packaged monk fruit sweetener, read the label. You’ll find conversion instructions to help you avoid overdoing it.
