Dietary Intake and Food Sources of Niacin, Riboflavin, Thiamin and Vitamin B₆ in a Representative Sample of the Spanish Population. The Anthropometry, Intake, and Energy Balance in Spain (ANIBES) Study †.

Thiamin, riboflavin, niacin, and vitamin B₆ are essential micronutrients that are mainly involved in energy metabolism; they may prevent the occurrence of developmental abnormalities and chronic degenerative and neoplastic diseases. The aim was to analyze dietary intake and food sources of those four nutrients in subjects ( = 2009) aged 9⁻75 years old from the Spanish ANIBES (Anthropometry, Intake, and Energy Balance in Spain) study. Dietary data were collected by means of a validated, photo-based three-day dietary food record. Underreporting was analysed according to the European Food and Safety Authority (EFSA, Parma, Italy) protocol. Mean (max⁻min) reported intake for the whole population of thiamin was 1.17 ± 0.02 mg/day, (0.30⁻3.44 mg/day), riboflavin 1.44 ± 0.02 mg/day, (0.37⁻3.54 mg/day), niacin 29.1 ± 0.2 mg/day (6.7⁻109 mg/day), and vitamin B₆ 1.54 ± 0.01 mg/day (0.28⁻9.30 mg/day). The main sources of intake for thiamin, niacin, and vitamin B₆ were meat and meat products, and for riboflavin were milk and dairy products. An elevated percentage of the Spanish ANIBES population meets the EFSA recommended intakes for thiamin (71.2%), riboflavin (72.0%), niacin (99.0%), and vitamin B₆ (77.2%).
