The influence of yacon syrup on the cardiovascular system and cholesterol
In a rat study, it was shown that taking yacon syrup in the diet in the company of fatty acids caused a decrease in blood triglyceride levels by about 40%.At the same time, no changes in the absorption of cholesterol were noted.This is probably related to the inhibition of triglyceride synthesis in the liver.It seems that the fructooligosaccharides contained in the syrup reduce fat obesity resulting from excess fructose in the diet.In a group of obese people with dyslipidemia, for 120 days, yacon syrup was administered in an amount that provided 140 mg of fructooligosaccharides per kilogram of body weight (10 gu of a person weighing 70 kg).It was found that the level of LDL cholesterol in the blood was reduced without a clear decrease in total cholesterol and without affecting the HDL fraction.
The effect of yacon on the level of glucose in the blood
