Hey everyone! Our Yacon Syrup is extremely popular because of how good it is for the gut and its potential to help people slim down. On top of that, it’s a really good-tasting, low-glycemic sweetener – just 7 calories per teaspoon.
1. Concentrated FOS
FOS (fructooligosaccharides) are prebiotic sugars found in many plants, but never in concentrations as high as in yacon roots. Yacon juice is 40–70% FOS, and concentrating it into syrup packs even more into every teaspoon. → See Gut Health.
2. Straight to the Colon
Yacon’s FOS resist digestion in the upper digestive tract, so they go straight to the colon. There, they’re completely fermented by beneficial bacteria like Bifidus and Lactobacillus, producing short-chain fatty acids like butyrate and acetate – postbiotics. Animal studies found yacon reduced intestinal permeability and improved the intestinal barrier and mucosal immunity.
3. The 4-Month Study
In a clinical study, women took a teaspoon of yacon syrup 3–4 times a day for 4 months with no diet changes. On average they lost 33 lb and 4 inches from their waist, while the placebo group gained 3.5 lb. BMI dropped from 34 to 28, bowel movements went from 0.28 to 0.99 per day, fasting insulin fell 42%, insulin resistance fell 67%, and LDL fell 29%. All reported feeling fuller, which researchers linked to the FOS slowing stomach emptying. → See Weight Loss.
4. A Sweetener That Helps
It’s a sweetener that seems to have only positive effects on insulin. Put it in juice, water, coffee or food. It pairs nicely with Rose Hips and Sea Buckthorn in a weight-management routine.
How Much to Take
1 teaspoon 3–4 times a day, the amount used in the study. More than that may cause extra gas.
