    Abstract:
    BACKGROUND: Folates and vitamin B12 are key nutrients in one-carbon metabolism and related diseases. Updated and plausible information on population intakes and their major dietary sources is scarce and urgently needed in Spain in order to increase the knowledge that can lead as previous step to prevention by fortification and supplementation policies. AIMS: The present study aims to evaluate main dietary folate and vitamin B12 sources and intakes in the Spanish population. MATERIALS AND METHODS: Results were derived from the ANIBES cross-sectional study using a nationally representative sample of the Spanish population (9-75 years, n = 2,009). RESULTS: Food groups with the highest mean proportional contribution to total folate intakes in both males and females were vegetables (21.7-24.9%) and cereals (10.7-11.2%), while meat and meat products (26.4%) and milk and dairy products (27.3%) were for B12. Total median folate and B12 intakes amongst women were 156.3 μg/d and 4.0 μg/d while for men were 163.6 μg/d and 4.5 μg/d, respectively. In all age groups, vitamin intakes were significantly higher in plausible than in non-plausible energy reporters. CONCLUSION: A limited number of participants had adequate folate intakes, whereas vitamin B12 intakes were adequate for practically the entire population. There is a clear need for improving folates intake in the Spanish population.
