BACKGROUND Several studies have reported inverse associations between folate intake and colorectal carcinoma risk. Few were prospective studies and none evaluated the association between the intake of individual folate vitamers and colorectal carcinoma risk. METHODS The aim of the current study was to investigate the relationship between dietary folate intake and the risk of colorectal carcin...
BACKGROUND Serum folate concentration is lower in individuals with the methylenetetrahydrofolate reductase (MTHFR) 677TT genotype than in those with the MTHFR 677CC or 677CT genotypes. Since studies considering folate intake are limited, we examined the association between folate intake and serum folate levels, according to the genotype. METHODS The subjects comprised 170 Japanese persons (74...
We studied non-hospitalized 30-69 y-old Japanese subjects to ascertain the influences of a 677C-T methylene-tetrahydrofolate reductase (MTHFR) genotype, nutritional intake and lifestyle-related factors on plasma homocysteine (Hcys) and serum folate concentrations. Hcys was higher and serum folate was lower in males than in females (p < .01). The Hcys concentration was higher in the VV group tha...
To investigate the relationship between folate status and dietary folate intake in the Taiwanese elderly, we analyzed plasma folate levels and dietary folate intake in 725 males and 705 females aged 65-90 years, sampled from the Elderly Nutrition and Health Survey in Taiwan (1999-2000) (Elderly NAHSIT). Results showed that the mean plasma folate levels were 22.9+/-1.4 nmol/L (10.1+/-0.6 ng/ml) ...
BACKGROUND Folate is a B vitamin involved in one-carbon metabolism and has been postulated to influence the risk of breast cancer. However, epidemiologic studies of folate intake in relation to breast cancer risk are inconclusive. We examined the association between dietary folate intake and the risk of breast cancer by estrogen receptor (ER) and progesterone receptor (PR) status of the breast ...
BACKGROUND Previous observational studies regarding the existence of an association between folate intake and the risk of breast cancer have been inconsistent. This study aimed to summarize the evidence regarding this relationship using a dose-response meta-analytic approach. METHODOLOGY AND PRINCIPAL FINDINGS We performed electronic searches of the PubMed, EmBase, and Cochrane Library databa...
Introduction: Folate plays an important role in cell metabolism, but international studies show that intake is currently below recommendations, especially among women. The study objective was to identify folate food sources by food group, gender, and age group, and to identify factors influencing folate intake, based on food consumption data for Swedish adults in the 2010-11 Riksmaten study. Me...
The aim of the present study was to develop and validate a folate food frequency questionnaire (FFQ)1 designed to measure dietary folate equivalents. The self-administered FFQ containing 39 items and a reference period of 1 month (i.e. the previous month), was validated against three biomarkers: serum and erythrocyte (RBC) folate, and plasma homocysteine (Hcy). Subjects were women (n=99) betwee...
Folate plays an important role in the synthesis and methylation of DNA as a cofactor in one-carbon metabolism. Inadequate folate intake has been linked to adverse health events. However, comparable information on dietary folate intake across European countries has never been reported. The objective of the present study was to describe the dietary folate intake and its food sources in ten countr...
