Abstract:

Objective To explore the correlation between the intake of different dietary nutrients with fasting blood glucose (FBG) and insulin resistance (IR). Methods Based on the data of the China Health and Nutrition Survey(CHNS), the data of 1 376 samples were included by matching the basic demographic data and serological test results with ID. The differences in fasting blood glucose of people with different nutrient intake groups, and their correlation with IR indexes were analyzed. Results Serum total cholesterol, triglyceride, LDL-C and serum uric acid in prediabetes group and diabetic group significantly increased, especially in the latter group (P<0.05). FBG was significantly higher in the highest quartile of fat intake group than that in the lowest quartile of fat intake group (5.38±1.34 vs 5.06±1.10 mmol/L, P=0.017). It was positively correlated with fat intake (r=0.1122, P<0.01), but not correlated with carbohydrate and protein intake (both P>0.05). In addition, fat intake was correlated with Homeostatic model assessment of insulin resistance(HOMA-IR) (r=0.0525, P =0.051), and negatively correlated with the Homeostatic model assessment of insulin sensitivity (HOMA-IS) (r=-0.0520, P=0.053) and Homeostasis model assessment for beta-cell function (HOMA-β) (r=-0.0681, P=0.011). Conclusion Fat intake is closely correlated with the increased FBG and IR in healthy population, although the specific mechanism needs to be further explored.
