Interpretive Summary:

Technical Abstract: Background: Elevated fasting blood glucose ranges from normal glucose tolerance (under 100 mg/dL) to impaired glucose tolerance (100-125 mg/dL) to diabetes mellitus (above 126 mg/dL). Dietary intake may have a direct influence on glucose metabolism. Objective: We hypothesized that dietary carbohydrate intake will be correlated with fasting blood glucose. Design: Participants (n=12) selected were a subset of “The Glycemic Effect of Honey” study sample. Individuals were recruited who exhibited both normal and impaired glucose tolerance. At baseline, fasting blood glucose levels were determined by Accu-Chek results are presented as mg/dL. Participants completed the Diet History Questionnaire II (DHQ II) online and the resultant energy, carbohydrate, protein, total fat, total sugar, fructose, glucose, sucrose, galactose, lactose, maltose, and starch were used for analysis. Reported nutrient intake was correlated to blood glucose using the fitted line regression on Minitab (version 15). Results: Blood glucose is related to reported total energy intake (P=.005) as well as total fat (P=.051), carbohydrate (P=.003), protein (P=.021), total sugar (P=.003), fructose (P=.015), glucose (.006), and sucrose (.002), galactose (P=.046), lactose (P=.037), and maltose (P=.009). Blood glucose is not largely statistically related to reported starch intake (P=.15). Conclusions: The reported dietary carbohydrate intake including reported energy, total fat, total protein, total sugar, fructose, glucose, sucrose, galactose, lactose, and maltose directly correlated to fasting blood glucose levels however reported starch intake did not. This information can be assessed further with a larger sample size to improve significance.
