Existing evidence suggests that the type of dietary fat may influence the metabolism of glucose. The aim of this study was to assess the relationship between the type of dietary fat and blood glucose.
Materials and methods
In this cross-sectional study, 12600 individuals were selected among adults aged over 19 years in three provincial cities of Isfahan, Najaf-Abad and Arak, using random-cluster sampling method. The frequency of food consumption in samples was assessed with a food frequency questionnaire.
There was a significant positive relationship between fasting blood glucose and consumption of foods containing polyunsaturated fatty acids (PUFA) in Arak (P=0.040). In all three provinces, age had a significant relationship with fasting blood glucose, 2-hour post load plasma glucose, waist-to-hip ratio, BMI (Body Mass Index), and waist circumference (P<0.001). A significant negative relationship with all of the variables except fasting blood glucose was seen in males (P<0.001).
In Isfahan, consumption of foods containing PUFA displayed a significant positive relationship with BMI (P=0.002) and waist circumference (P<0.001). In Najaf-Abad, consumption of PUFA sources was significantly and positively related to BMI and waist circumference (P<0.001). In all of the three provinces, the pattern of fat consumption in diabetics was healthier than in non-diabetics.
People (in the areas under study) have inadequate nutritional knowledge of dietary fats. Disease constitutes an important motive for patients to modify their lifestyles. Thus, people's awareness of the importance of disease prevention will increase following interventions in Isfahan Healthy Heart Program.
