Luo Han Guo fruit and its benefits, review of side effects
October 22 2016 by Ray Sahelian, M.D.

Luo han guo is a very sweet fruit found in China. Extracts (also spelled Luo han kuo or
lo han kuo) are now being marketed as a sweetener. The amounts normally used are so small that luo han guo is not likely to have any appreciable effect on human physiology.

My experience
I keep luo han guo on my kitchen counter and use it occasionally to sweeten teas. It is low-calorie, has a fruity sweetness, and I would recommend it as an alternative to sugar and artificial sweeteners. It's great that we now have two low or no-calorie alternatives to traditional sweeteners:
stevia and Luo han guo. I prefer Stevia since it is a much more potent no calorie sweetener.
Another sweetener to consider is D Mannose.

Lo Han Kuo is the fruit of Momordica grosvenori, a plant cultivated in the mountains of southern China. Mogrosides, which are water extracted from the Lo Han fruit, offer a pleasant, sweet taste without elevating blood sugar. Lo Han Kuo Mogrosides are up to 250x sweeter than sugar.

Xylitol, a naturally occurring polyol, is sweet with a distinct cooling sensation in the mouth. Xylitol is metabolized differently from a conventional sugar and does not cause or contribute to tooth decay. Xylitol is as sweet as sugar, having 40% less calories.

Inulin-FOS (FructoOligoSaccharide) is a soluble fiber and promotes beneficial intestinal bacterial growth.

About the plant
Lo Han Guo (Siraitia grosvenori) is a perennial vine native to the Guangxi province in southern China. The mountains of Guilin in this region provide the ideal environment for the vine, allowing it to thrive in warm, shaded mists. These vines grow 10 to 15 feet long, wrapping their tendrils around and climbing over other plants. Lo Han Guo is particularly prized for its round, sweet-tasting fruits, which are harvested while green and become brown when dried.

Biosci Biotechnol Biochem. 2010. Digestion and absorption of Siraitia grosvenori triterpenoids in the rat. When administered to rats, mogroside V (a pentaglucose-conjugated mogroside), the main sweetening component of Siraitia grosvenori, was mostly degraded by digestive enzymes and intestinal microflora, and was excreted in the feces as mogrol (aglycone) and its mono- and diglucosides. However, trace amounts of mogrol and its monoglucoside were found in the portal blood as sulfates and/or glucuronide conjugates.

Nutr Res. 2008. Mogrosides extract from Siraitia grosvenori scavenges free radicals in vitro and lowers oxidative stress, serum glucose, and lipid levels in alloxan-induced diabetic mice.

For those who do not want to trigger their insulin, and who are watching their weight, is Luo Han Gao product considered a good sugar alternative?
     A. Thus far it appears to be a good choice, along with stevia natural sweetener. You can alternate the two.
