Monkfruit–The Curiously Sweet, Low Calorie Natural Sweetener

You may have seen an interesting new ingredient on your healthy food products lately and have been wondering exactly what it is. Monk fruit, or lo han guo, is a small green melon from China with a very sweet taste—but zero calories as a sweetener and zero carbs. It also does not raise blood sugar levels. This sweet little secret has been around for decades, but is just now making its way into mainstream foods as a healthy, zero calorie, natural alternative sweetener.

We’ve had a variety of choices for low calorie sweeteners over the years. However, most of them have previously met with negative reviews due to potentially serious health issues.

Consider for example, these low-calorie artificial sweeteners that have been on the market (all approved by the FDA):

• saccharin/SweetN’Low
• aspartame/NutraSweet
• sucralose/Splenda
• neotame/Newtame
• acesulfame potassium/Ace-K, Sunett, Sweet One


All of these have been found to have adverse health effects, negatively affect the gut microbiome, have links to some types of cancers, increase appetite and actually cause weight gain.

Saccharin or benzoic sulfinide, was discovered by a scientist studying coal tar derivatives. This coal tar derivative was considered a cancer risk and has been a controversial sweetener ever since.

Aspartame, or NutraSweet as it is called, has been found to be neurotoxic and the excitatory amino acids in it can cause long term damage to the brain neurons. One of aspartame’s primary ingredients, phenylalanine, blocks the production of serotonin in our gut, which not only negatively affects moods, causing anxiety and depression, but low serotonin also brings on food cravings—especially for sweet, starchy foods. Result is often weight gain.

While sucralose was marketed as a safer artificial sweetener called Splenda, it is a chemically created compound modified by adding chlorine atoms to sugar. This is like ingesting small amounts of chlorinated pesticides. Oh, and by the way, sucralose was discovered in the 1970’s by scientists who were working on creating a new pesticide.

Many people are actually allergic or sensitive to artificial sweeteners and can have reactions ranging from an itching, oozing rash, hives, eczema to nausea, diarrhea, and wheezing.


Artificial sweeteners have been found to disrupt our microbiome in our gut as well, causing a big drop in serotonin production. This can lead to a variety of digestive problems, brain dysfunction and mood disorders including:

• Migraines/headaches
• Gut dysbiosis
• Asthma
• Anxiety
• Stroke, dementia, Alzheimer’s
Brain tumors
• Sperm damage
• Kidney dysfunction

Artificial sweeteners also trigger insulin release and increase appetite, defeating the purpose for which they are used in the first place—causing cravings, excessive eating and weight gain.

Stevia, a natural sweetener derived from the stevia plant, has been used for years as a safe and natural alternative to artificial sweeteners. Stevia, however, when used in its more natural form, can have an unpleasant aftertaste that is bitter or metallic tasting. And, some people actually have allergic reactions to stevia. Many of the commercially marketed stevia products are mixed with dextrose, erythritol, and lactose, making them nutritionally much different and iffy as far as being a healthy sweetener.


Enter monk fruit. Monk fruit has traditionally been used in herbal medicine and has a naturally sweet taste. Monk fruit contains something called mogrosides, which are intensely sweet.

Monk fruit sweetener has several health benefits as a natural sweetener. It has zero calories, zero carbohydrates and no harmful side effects–like the FDA-approved artificial sweeteners listed above.

Monk fruit also contains antioxidants and does not raise blood sugar, making it safe for diabetics or weight loss. According to this 2011 study, monk fruit has been safely used in traditional Chinese medicine for many, many years. One of its uses is to relieve sore throats and minimize phlegm in colds and flu.

And since monk fruit has been used for centuries, it is a safe and healthful sweetener. The Food and Drug Administration has determined that monk fruit is “generally recognized as safe (GRAS)” for everyone, including pregnant women and children.

However, outside of traditional Chinese medicine, monk fruit mass is just now beginning to be mass marketed, so more scientific studies will have to be done to determine its overall effects.

The downside of monk fruit includes the fact that monk fruit is difficult to grow and harvest–and it spoils easily–so it is still a fairly expensive product. While it is gaining in popularity, it is still tricky to find monk fruit sweetener at your local grocery or health food store.


Monk fruit does have a little bit of a bitter or strange aftertaste, depending on the food or drink it is included in. Monk fruit sweeteners can be used in coffee, tea, salad dressings, sauces, baked goods, and even as a sweetener in collagen and protein powders.

While monk fruit has zero calories and carbohydrates, be careful because most baked goods, smoothies and other drinks still have plenty of calories on their own, and can fool you into thinking you are not eating any calories.

Monk fruit is a member of the Curcurbitaceae family, which includes pumpkin, cucumbers, squash, and melons. If you are allergic to any of these foods, you may be allergic to monk fruit.

While monk fruit may need further research to study all of its health impacts, it seems to be a great, natural alternative to other artificial sweeteners—and great for anyone who wants to limit sugar in their diet. Especially those with diabetes or following a weight loss diet. While there are a few claims about monk fruit’s ability to prevent cancer or other health problems, more research is needed.

  1. There is only one mention in the article about Erythritol, but no comment. This is a no cal, no carb crystalline sweetener, very similar to sugar, but 70% as sweet. Slight coolness effect, like glucose, but a pleasant taste

  2. Yes, you are right. We have monk fruit sweetener in Australia but only 1% Monk fruit. The rest is Erythritol. I’m wondering if this is still ok?

    Thank you for your added comment. I was thinking the same thing. ???‍⚖️?
