BACKGROUND Epidemiological studies evaluating the association between folate intake and risk of pancreatic cancer have produced inconsistent results. The statistical power to examine this association has been limited in previous studies partly because of small sample size and limited range of folate intake in some studies. METHODS We analyzed primary data from 14 prospective cohort studies th...
Laboratory and human studies suggest that folate intake may influence the risk of some cancers. However, prospective information about the relation between folate intake and the risk of exocrine pancreatic cancer is limited. The authors examined the relation of dietary folate intake to the risk of pancreatic cancer in two large prospective US cohorts. Folate intake was assessed by food frequenc...
OBJECTIVE To evaluate factors associated with the risk of low folate intake among adolescents. METHODS We employed cluster sampling, using a random selection of 40 representative census sectors and households within those sectors, including all individuals between 10 and 19 years of age. The weight, height and skin folds of subjects were measured and socioeconomic data on their families were ...
background: oxidative stress is detrimental to semen quality and has a significant role in the etiology of male subfertility. methods: dietary intake of antioxidants were compared between thirty two men with oligolastheno/ teratazoospermic (cases) and 32 normospermic volunteers (controls) attending fertility clinic in mirza koochak-khan hospital in tehran, iran. all participants were nonsmokers...
Sporadic colorectal cancer (CRC) is characterized by genetic and epigenetic changes such as regional DNA hypermethylation and global DNA hypomethylation. Epidemiological and animal studies suggest that aberrant DNA methylation is associated with low dietary folate intake, which is aggravated by high alcohol intake. The relationship between promoter methylation of genes involved in CRC carcinoge...
Background: Oxidative stress is detrimental to semen quality and has a significant role in the etiology of male subfertility. Methods: Dietary intake of antioxidants were compared between thirty two men with oligolastheno/ teratazoospermic (cases) and 32 normospermic volunteers (controls) attending fertility clinic in Mirza Koochak-khan Hospital in Tehran, Iran.

This study assessed folate intake, folate concentrations in plasma and erythrocytes, plasma total homocysteine (tHcy) concentrations, and urinary excretion of folate metabolites in Korean women of childbearing age. A total of 36 women voluntarily participated in this study. Precise dietary intake for 3 consecutive days was determined by weighing all foods consumed, and folate intake was calcula...
Epidemiologic evidence indicates an inverse association of folate intake with risk of colorectal cancer, but whether this association is modified by intake of caffeine (in coffee and tea) or cigarette smoking—factors that possibly interfere with folate—has not been studied. Thus, we examined whether the association between dietary folate intake and incidence of colorectal cancer is modified by ...

introduction: there is no comprehensive study on the effect of folate on food intake therefore the present study was carried out to determine the effect of folate supplementation on serum concentrations of leptin and grehlin and food intake in male wistar rats. methods: the study was carried out for 42 days during which the animals were weighed weekly their food and water intakes were measured ...
