Folate, methionine, betaine, choline, zinc and Vitamins B(12), B(6) and B(2) are involved in one-carbon metabolism, which includes S-adenosylmethionine (SAM) substrated methylation. Inadequate enzyme activities and imbalances of substrates and cofactors in one-carbon metabolism, together referred to as the 'methyldietary' constituents, may cause homocysteine and S-adenosylhomocysteine accumulation. Hyperhomocysteinemia is associated ...

For decades, the traditional food folate extraction method involved two steps including heat treatment, to release folate from its binding proteins, and folate conjugase treatment, to hydrolyze polyglutamyl folate to monoglutamyl folate. However, a trienzyme-extraction method of food folate was developed in the mid 1990s. This method involves the use ...

Only very small quantities of vitamins and minerals are needed for human health but deficiencies can have disproportionately large, often life-threatening, effects. Micronutrient deficiencies lead to a vicious cycle of malnutrition and infection in poorly nourished populations. Fortification of staple foods is the cheapest, most efficient and most effective way ...
Bower Carol - - 2004
BACKGROUND: Since the publication of randomized controlled trials demonstrating the prevention of neural tube defects (NTDs) with periconceptional folate, several Australian states have promoted an increase in periconceptional use of folic acid supplements. Since 1996, voluntary fortification of food with folate has been allowed in Australia and New Zealand for ...
McNulty Helene - - 2004
The achievement of optimal folate status to prevent neural-tube defects, and possibly other diseases, is hindered by the well-recognised incomplete bioavailability of the natural folates found in foods compared with the synthetic vitamin, folic acid. Folate bioavailability from different foods is considered to be dependent on a number of factors, ...

Folic acid deficiency is very rare in Japan. However, recent concerns in relation to causal relationships between cancer and low folic acid levels necessitate information on actual folate intake by Japanese, which has hitherto not been well studied. We therefore evaluated folate contents of a hospital diet for 7 consecutive ...
