Prevalent low Mediterranean diet adherence and low folate status in a Spanish Km 0 Mediterranean coast population.

ABSTRACT:

Background

Folate, vitamin B₁₂, riboflavin, and vitamin B₆, play interrelated roles in one-carbon metabolism, vital for several physiological processes.

Objective

To assess intake and status of these B-vitamins in an adult Mediterranean population unexposed to mandatory food fortification or B-vitamin supplementation, and to examine the associations with Mediterranean diet adherence (MDA).

Methods

A representative sample of adults aged 18-77 (n = 740) provided fasting blood samples and 3-day dietary records. MDA was assessed using the Trichopoulou score. Plasma folate, red blood cell folate (RBCF) and plasma vitamin B₁₂ were measured via microbiological assays. Riboflavin and vitamin B₆ status were determined by erythrocyte
