The Effects of Jerusalem Artichoke and Fermented Soybean Powder Mixture Supplementation on Glucose Control

The objective of this clinical study was to evaluate the effect of jerusalem artichoke and fermented soybean powder mixture supplementation on blood glucose. A randomized, double-blinded, placebo-controlled study was conducted on 60 subjects with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or newly diagnosed type 2 diabetes. The subjects were randomly assigned to either a group ingesting 40 g jerusalem artichoke and fermented soybean powder mixture supplementation daily or a placebo group for 12-week. We assessed fasting and postprandial levels of glucose.

Inclusion criteria

• All subjects were with prediabetes (IFG or IGT) or newly diagnosed type 2 DM (T2DM) no taking medicine. IFG was defined as fasting glucose between 100 and 125 mg/dL and IGT was defined as 2-h OGTTs glucose levels 140-199 mg/dL. Newly diagnosed type 2 diabetes was defined as fasting glucose ≥126 mg/dL or 2-h OGTTs level ≥ 200 mg/dL.

Exclusion criteria

• glucose lowering medications or insulin injections;
• abnormal liver or renal function;
• chronic stomach and intestines disease;
• chronic alcoholism;
• pregnancy or intending to become pregnant during time of study.
• complications;
• an occupation that could be dangerous if hypoglycemia should occur.
