Abstract
Background: Cardiovascular diseases are the first cause of death in Iran and hypercholesterolemia is one of the most important risk factors. This problem could be partially managed by dietary modifications such as supplementation of diet with dairy products and probiotic bacteria. The aim of this study was to comprise the effect of consuming a probiotic yoghurt and ordinary yoghurt on serum cholesterol levels in mild to moderate hypercholesterolemia.
Methods: This randomized cross-over trial was conducted on 14 healthy subjects aged 40-65 years with total serum cholesterol 200-300 mg/dl. We asked the subjects to avoid consumption of yoghurt for a two-week pre-study period and add 300 g/day of milk to their diet. Then they were randomly allocated to 2 groups to receive either 300 g of ordinary yoghurt (fermented with S.thermophilus and L.bulgaricus) or probiotic yoghurt (fermented with a starter composed of L.acidophilus and B.lactis plus bacteria in ordinary yoghurt) for 6 weeks as substitution for milk. After a wash-out period of 7 weeks, the cross-over was made (those consuming probiotic yoghurt, changed to ordinary yoghurt and vice versa) and the study lasted for another 6 weeks. Anthropometric measurements, a 3-day dietary recall and blood lipid tests were done at the beginning (after a 2-week elimination period of yoghurt from diet) and at the end of each period.
Results: Comparison of weights, BMIs and dietary confounding factors during the period of consuming ordinary yoghurt and probiotic yoghurt, did not show any significant differences. Consumption of probiotic yoghurt in comparison with ordinary yogurt caused a significant decrease in total serum cholesterol (P=0.049). Comparison of other blood lipid criteria did not show any significant differences between these two periods.
Conclusion: Consumption of the yoghurt containing two probiotic bacteria, L.acidophilus and B.lactis, in comparison with ordinary yoghurt causes reduction in total serum cholesterol in mild to moderate hypercholesterolemia.

Abstract
Background: Medical-nutritional interventions, can reduce the risk of complicationsin T1DM. There has been some conflicting data on the issue of the association between diabetes knowledge and metabolic improvement of T1DM patients. Therefore the aim of this study was to evaluate the effect of nutrition education on biochemical changes, nutritional status, knowledge, attitude and practice of patients withT1DM in Aligoodarz.
Methods: This study was a self – control quasi survey. Census sampling was used for subject selection. ِِData was collected by observation and interview techniques. Biochemical indices were measured on blood samples by standard methods and anthropometric measurements, diet survey and KAP study were carried out on 30 patients with T1DM by a nutritionist at the first and 3 months after training. All cases participated in educating programs for 12 hours. The results were analyzed by SPSS and Food processor softwares and results compared with paired t-test and McNemar test. P-values less than 0.05 were considered as significant.
Results: 30 patients with 15 – 45 years old ( Mean ± SD = 30.8 ± 11.3 ) participated in study all participants were educated. Mean duration of diabetes was 10.9±6.44 years. FBS, HbA1c, total cholesterol and LDL-C levels decreased significantly. After educating interventions also hypoglycemic attacks reduced. Macronutrients intake were in recommended ranges for diabetic patients. Simple carbohydrates and cholesterol intakes decreased and dietary Folate, Vit c and fiber increased. Calcium intake was less than RDA. Both knowledge and practice scores increased significantly (P<0.001). Attitude was changed for some items significantly.
Conclusion: Findings of this project emphasyzed on the importance of nutrition education to patients with T1DM. It may significantly changes biochemical indices, dietary fiber and simple carbohydrate and improves metabolic control in T1DM. And the patients KAP scores increased. Thus appropriate nutrition education as well as insulin therapy are the main factors in metabolic control of T1DM.
