OBJECTIVES: The periconceptional intake of 0.4 mg folic acid is recommended in many countries to prevent neural tube defects. This paper describes the poor implementation of corresponding guidelines in Germany, the effectiveness of an intervention-based on providing adequate information and the problems associated with the implementation. METHODS: Two cross sectional ...

Biocidal activities of monochloramine and peracetic acid were studied on cysts of Naegleria lovaniensis. Until recently the most commonly used biocide to disinfect cooling water systems was hypochlorite. Owing to its negative impact on the aquatic environment, ecologically less harmful alternatives have been sought. As the biocidal activity of monochloramine ...

Data about folate intake and blood values of the German population, published between 1997 and 2000, have been reviewed. Median folate intake is about 250 micrograms/day in the adult population, which indicates a high likelihood of inadequate intake when compared to the Estimated Average Requirement (EAR) of 320 micrograms/day. Only ...

The Texas-Mexico border population has a high prevalence of neural tube defects (NTDs). In 1998, in an effort to reduce the risk of NTD-affected pregnancies, the US Food and Drug Administration mandated folic acid fortification of enriched grain products. Since then, the median serum folate and red blood cell (RBC) ...

BACKGROUND: The association between vascular disease and elevated plasma total homocysteine (tHcy) concentrations is caused, in part, by inadequate intakes of dietary folate. Increasing folate intake either through supplements or foods naturally rich in folates has been shown to decrease tHcy concentrations. OBJECTIVE: The aim of this study was to ...

Folate catabolism represents the major route of folate turnover in humans and involves cleavage of the C9-N10 bond producing a pterin and para-aminobenzoylglutamate (pABG). Thus, the quantitation of pABG and its acetylated more predominant counterpart para-acetamidobenzolyglutamate (apABG) may be useful in assessing folate status and requirements. However, until the in ...

Our knowledge on the absorption of folate is incomplete. The deconjugation process as a possible limiting factor in the absorption of folates was investigated. The study also attempted to validate the use of the area under the serum response curve (AUC) from food compared with folic acid as a proxy ...

BACKGROUND: Betaine (Bet) supplementation is an effective strategy for dietary treatment of homocystinuria. However,previous reports on diet therapy have only examined methionine (Met)and cystine concentrations, but not those of Bet and homocysteine(Hcy) in food items. We set up a hypothesis that there are some food items, which contain a small ...

Dietary folate consists of monoglutamate and polyglutamate folate species. In the small intestine, folate polyglutamate is deconjugated to the monoglutamate form before absorption takes place. This enzymatic deconjugation might limit the bioavailability of polyglutamate folate. Until now, no data have been available on dietary intake of both folate forms and ...

The American public receives conflicting messages from dietitians, nutritionists, physicians, and manufacturers regarding food supplements. Consumers commonly distrust scientists and justify supplement use based upon word of mouth and friendship patterns. Scientific-based education regarding supplement use is vital in the present atmosphere where consumer misinformation is rampant.

Dietary advice to breastfeeding mothers in post-World War II Queensland, 1945-1965, was not evidence-based, but based on cultural beliefs. Diet-based recommendations for boosting the breastmilk yield included increased intake of milk and protein foods, food supplements, especially chocolate-flavoured supplements, and tablets. Although community beliefs about foods to be avoided during ...

A method is described for the determination of anabolic steroids including testosterone, 19-nor-4-androstene-3,17-dione, 4-androstene-3,17-dione and nandrolone in food supplements. Initial clean-up is done by HPLC followed by determination with GC/MS. A 'contaminated' food supplement was analysed and appeared to contain 19-nor-4-androstene-3,17-dione and 4-androstene-3,17-dione. One capsule of this nutritional supplement was ...

Most randomised placebo-controlled trials show no benefit of phytoestrogens in managing menopausal vasomotor symptoms. Concentrated phytoestrogen supplements appear to have oestrogenic actions in the breast and may interfere with the therapeutic use of tamoxifen. Unlike concentrated supplements, foods rich in phytoestrogens, such as vegetables, grains and legumes, are also excellent ...
