Refined carbohydrate intake in relation to non-verbal intelligence among Tehrani schoolchildren.

Objective: Nutrition has long been considered one of the most important environmental factors affecting human intelligence. Although carbohydrates are the most widely studied nutrient for their possible effects on cognition, limited data are available linking usual refined carbohydrate intake and intelligence. The present study was conducted to examine the relationship between long-term refined carbohydrate intake and non-verbal intelligence among schoolchildren.

Fruits and vegetables consumption and esophageal squamous cell carcinoma: a case-control study.

The authors examined the association of food group intakes and the risk of esophageal squamous cell carcinoma (SCC) in a hospital-based case-control study in Iran. In total, 47 patients with esophageal SCC and 96 controls underwent face-to-face private interviews. Usual dietary intake was assessed using a semiquantitative food frequency questionnaire.

Dietary patterns and risk of oesophageal squamous cell carcinoma: a case-control study.

Objective: We conducted a hospital-based, case-control study to examine the association between dietary patterns and the risk of oesophageal squamous cell carcinoma in Iran.

Design: A total of forty-seven patients with oesophageal squamous cell carcinoma and ninety-six controls underwent face-to-face interviews. Factor analysis was used to detect dietary patterns.

Efficacy of folate and vitamin B12 in lowering homocysteine concentrations in hemodialysis patients.

To evaluate the efficacy of supplementation with high dose folic acid with and without vitamin B 12 in lowering plasma total homocysteine (tHcy) concentrations in hemodialysis (HD) patients, we studied 36 HD patients randomized into four groups according to the received therapeutic regimen: group I (only folic acid (FA), 5 mg/day), group II (FA, 5 mg/day + vitamin B 12 , 1 mg/day) group III (only FA, 15 mg/day), group IV (FA, 15 mg/day, vitamin B 12 , 1 mg/day) for a period of 8 weeks. Plasma tHcy and serum FA and vitamin B 12 levels were measured at baseline and after the supplementation period. Dietary intakes were assessed during the study period.
