Concept of dietary patterns is new in the filed of nutritional epidemiology. However, it has not been focused to the extent that foods or nutrients have been considered. Although, identifying the association between nutrients and foods intake with chronic diseases is valuable yet, recent evidences have shown that the clinical trials that have used nutrients are not too successful to indicate the effects of that nutrient on the disease risk. On the other hand, the studies used dietary patterns have shown the significant effects on disease risk. Therefore, using dietary patterns analysis is an efficient method to identify diet-disease relations. However, it should be kept in the mind that dietary patterns are different across gender, ethnics, cultures and regions. It is, therefore, recommended that investigators in different countries need to assess their own community dietary patterns and emphasize on these patterns when trying to reduce chronic disease risk. The current study has been conducted to review the studies that have assessed the association of dietary patterns and chronic disease risk.

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.

Background: Recently on the metabolic syndrome is considered as an inflammatory disease. So factors affecting inflammation are important in this condition.

Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Inflammatory markers were measured by ELISA.

 Results: The difference from the control diet for E-selectin (an inflammatory markers which shows the endothelial function) was -11.4% (P<0.01) on the soy nut consumption and -4.7% (p=0.19) on the soy protein diets. Soy nut consumption reduced interleukin-18 compared to the control diet (difference from the control diet: -9.2%, p<0.01). For C-reactive protein the difference from the control diet was -8.9% (P<0.01) on the soy nut diet and -1.6% (P<0.01) on the soy protein diet.

Conclusion: Short-term soy nut consumption reduced some markers of inflammation and increased plasma nitric oxide levels in postmenopausal women with the metabolic syndrome.

Background: Little evidence exists regarding the effects of soy consumption on the metabolic syndrome in humans. We aimed to determine the effects of soy consumption on components of the metabolic syndrome, plasma lipids, lipoproteins, insulin resistance and glycemic control in postmenopausal women with the metabolic syndrome.

Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with the metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Red meat in the DASH diet was replaced by soy protein in the soy protein period and by soy nut in the soy nut period.

Results: Total cholesterol was significantly reduced compared to the control (P<0.01) and soy protein groups (P<0.01). The results were the same regarding the fasting insulin serum (P<0.01 compared with the control and soy protein group), HOMA-IR (P<0.01 compared with the control and soy protein group), Fasting blood sugar (P<0.01 compared with the control and soy protein group), and LDL cholesterol (P<0.01 compared with the control and P<0.05 compared with the soy protein group). Both soy nut and soy protein reduced Apo B100 compared to the control group (P<0.01).  

Conclusion: Short-term soy nut consumption improved glycemic control and lipid profiles in postmenopausal women with the metabolic syndrome
