Study summary

This study evaluates the effects of folate-rich foods regarding improvement of folate status compared with folic acid supplement. A randomized, parallel intervention trial with two active groups (folate-rich foods or folic acid supplement) and one control group (apple juice - 0 µg/d folate) was executed over 12 weeks.

Read the detailed description

Sixty-two women in reproductive age, apparently healthy, non-smokers, not consuming special diets (vegetarian), not pregnant, not planning conception or not lactating.

A randomized, controlled, parallel intervention trial with two active groups and one blinded control group was carried out for 12 weeks (March to June, 2013). The active food group (n = 21) consumed folate-rich foods (germinated canned faba beans, cookies, orange juice, providing additional 250 μg/d folate); the active folic acid supplement group consumed a supplement (n = 19, providing 500 μg/d folic acid); and the control group (n = 22) received apple juice containing no folate or folic acid) in addition to the freely chosen diet.

Fasted venous blood samples were collected at baseline, two months and three months for quantification of folate in plasma and erythrocytes and of homocysteine in plasma.
