Conclusion
Usual intake of 1C nutrients in male and female young Thai adults was adequate for vitamins B2, B6 and B12. The majority of participants had inadequate folate intake and did not achieve recommended intake levels for choline. The intake levels of vitamin B2 and choline were inversely associated with BMI in men. These findings are in line with reports in Western countries, suggesting that inadequate intake of folate and choline is not geographically constrained.
