Monk fruit extract is a natural sweetener that may help with calorie control, diabetes, immunity, and more. Still, the science behind it is young and warrants further investigation. Read on to learn about the benefits and side effects of this peculiar Asian fruit.<\/p>\n
<\/p>\n
Monk fruit (Siraitia grosvenori) <\/i>or Luo han guo is a fruit native to south-east Asia and a member of the gourd (Cucurbitaceae) family. It is named after the Buddhist monks who first cultivated the fruit nearly 800 years ago.<\/p>\n
It contains powerful antioxidants called mogrosides that are 250 times sweeter than table sugar (sucrose) [R<\/a>].<\/p>\n For this reason, monk fruit extract has been traditionally used as a natural, non-caloric sweetener<\/b> to replace sugar [R<\/a>].<\/p>\n Proponents<\/b>:<\/p>\n Skeptics<\/b>:<\/p>\n Monk fruit has:<\/p>\n Monk fruit extract contains mogrosides<\/b>, antioxidants that decrease blood vessel leakiness (permeability), inhibit histamine<\/a> release from mast cells, and prevent inflammatory damage.<\/p>\n Mogrosides are saponins, chemicals that prevent the excess leakiness of cell membranes (membrane hyperpermeability), which protects mitochondria<\/a> and DNA from oxidative damage [R<\/a>, R<\/a>, R<\/a>, R<\/a>, R<\/a>, R<\/a>].<\/p>\n Mogrosides also protect DNA by increasing the production of PARP<\/a>1, p53, and MAPK9 [R<\/a>].<\/p>\n They decrease inflammation by:<\/p>\n Monk fruit extract may improve glucose<\/a> and fat metabolism by reducing CREB<\/a> and activating AMPK<\/a> [R<\/a>, R<\/a>].<\/p>\n No clinical evidence supports the use of monk fruit extract for any of the conditions listed in this section. Below is a summary of the existing animal and cell-based studies; they should guide further investigational efforts but should not be interpreted as supportive of any health benefit.<\/i><\/p>\n Different compounds from monk fruit extract showed anti-cancer effects in preclinical research:<\/p>\n If used as a replacement for sugar, monk fruit extract may help limit the fuel (glucose) cancer needs to thrive and protect the genes that initiate cancer cell death (p53) [R<\/a>, R<\/a>, R<\/a>].<\/p>\n Clinical trials are needed to investigate the anticancer effects of monk fruit extract. At this point, we can\u2019t tell what role, if any, it may have in cancer prevention or treatment.<\/b><\/p>\n The therapeutic effects of monk fruit on diabetic rabbits was studied by administering an extract for 4 weeks. It significantly decreased sugar, total cholesterol, and triglyceride levels in the blood, while increasing HDL<\/a> cholesterol (\u201cgood\u201d cholesterol) [R<\/a>].<\/p>\n Monk fruit extract prevented the rise of blood sugar in mice when given 3 minutes before a high-sugar meal [R<\/a>].<\/p>\n It also reduced blood sugar and urinary albumin levels in diabetic rats, indicating that it may improve kidney damage caused by diabetes [R<\/a>].<\/p>\n Monk fruit extract decreased physical fatigue in mice in a dose-dependent manner. The treated mice had extended swimming times compared to the control group [R<\/a>].<\/p>\n The extract also enhanced endurance by increasing liver and muscle glycogen, while decreasing blood lactic acid<\/a> and serum urea<\/a> nitrogen (SUN<\/a>).<\/p>\n According to cellular research, monk fruit extract may stimulate mitochondrial function (by increasing PGC-1\u0251 activity) [R<\/a>].<\/p>\n Mogroside helps break down cholesterol and protect the liver from oxidative damage. In diabetic mice, mogroside treatment reactivated liver antioxidant enzymes (superoxide dismutase<\/a>, and glutathione<\/a> peroxidase<\/a>), which play a critical role in detoxification<\/a> [R<\/a>, R<\/a>, R<\/a>].<\/p>\n The fruit has been used for centuries in traditional Chinese medicine to treat a sore throat and cough.<\/p>\n A compound of monk fruit extract called siraitiflavandiol<\/i> is antimicrobial against the growth of Streptococcus mutans, Porphyromonas gingivalis, and<\/i> Candida albicans<\/i> in cell culture [R<\/a>].<\/p>\n In the lab, components of monk fruit prevented the growth of oral bacteria and fungal species [R<\/a>].<\/p>\n After repeated administration, monk fruit extract prevented allergic symptoms <\/b>(nasal rubbing or scratching) in mice. The mogrosides and extract inhibited the release of histamine from mast cells [R<\/a>].<\/p>\n Mogrosides significantly enhanced cellular immunity in immunosuppressed mice (by promoting phagocytosis and T lymphocyte<\/a> proliferation) [R<\/a>].<\/p>\n Keep in mind that the safety profile of monk fruit extract is relatively unknown, given the lack of well-designed clinical studies. The list of side effects below is not a definite one, and you should consult your doctor about other potential side effects, based on your health condition and possible drug or supplement interactions.<\/i><\/p>\n A review found that extracts and individual compounds in monk fruit are non-toxic according to existing research [R<\/a>].<\/p>\n Monk fruit juice concentrate is generally recognized as safe (GRAS) by the FDA as an ingredient in conventional food and infant and toddler foods [R<\/a>].<\/p>\n Just like with any other food, there\u2019s a possibility of monk fruit allergy. Monk fruit belongs to the Curcurbitaceae<\/i> (gourd) family, along with pumpkin, squash, melons, and cucumbers. People allergic to gourds should pay special attention.<\/b><\/p>\n The available forms include:<\/p>\n Both are zero-calorie, high-intensity sweeteners [R<\/a>].<\/p>\n Although monk fruit and stevia<\/a> are increasingly used as sweeteners, the number of studies on their health effects is limited [R<\/a>].<\/p>\n Monk Fruit Pros<\/b>:<\/p>\n Stevia Pros<\/b>:<\/p>\n The serving size of commercial monk fruit extracts ranges from 0.8-4 grams<\/b>.<\/p>\n The opinions expressed in this section are solely from the users who may or may not have a medical background.
