In the current human trial, the efficacy and safety of ingesting
new sweetener “RSS” over a 12-week period were
investigated by a randomized double-blind parallel experiment
for the first time. Significant reductions of body weight,
body fat percentage and waist circumference in the rare sugar
syrup group were observed compared to the high fructose corn
syrup group. We also confirmed that no adverse effects or abnormal
blood parameters were observed with regard to lipid
and carbohydrate metabolism, hepatic and renal functions. RSS
also gives natural sweetness, which resembles that of sucrose,
even if combined with high intensity sweetener, such as stevia,
sucralose, acesulfame-K or aspartame, because of its superior
masking ability. A calorie sweetener blended with RSS and
high intensity sweeteners might be a highly effective means
of countering obesity
