Vitamin B12 Supplementation Adequacy in Australian Vegan Study Participants

In our initial analysis of the Australian Vegan Study we estimated the mean daily intake of vitamin B12 of each participant and compared this to the Recommended Dietary Intake (RDI). However, the proportion of vitamin B12 that can be absorbed from large doses typically contained in oral supplements is considerably lower than the amount absorbed from food. In this analysis we took into account the estimated absorption from supplements in order to compare adequacy of vitamin B12 intake to the RDI. A cross-sectional online survey was used to obtain information from women (N = 1530) of reproductive age on a vegan diet in Australia. Vitamin B12 intake from food was estimated using a validated food frequency questionnaire and detailed questioning was used to estimate supplemental intake. We used published data on dose-dependent absorption rates to estimate amount of the vitamin absorbed to enable comparison to the RDI. Supplementation practices varied widely. Based on estimated amount absorbed, 39% of participants had an estimated total intake of vitamin B12 below RDI equivalency, compared to 26% based on mean daily intake. The potential absorption of vitamin B12 needs to be considered when estimating adequacy of intake and recommending supplementation.

Recently there has been an increase in the number of people adopting plant-based diets in many countries, mainly out of concern for animals but also for health and environmental reasons. The widespread adoption of a vegan diet could result in a substantial reduction in chronic disease and economic and climate-change benefits. However, there is a lack of international consensus on the safety and desirability of such diets for infants and children. This chapters explores the infant feeding guidelines for vegan parents.

(i) To examine demographic and health characteristics of women of reproductive age on a vegan diet in Australia and compare these to the general population; (ii) to identify sources and intake of vitamin B₁₂ and compare intake to current recommendations and (iii) examine associations between participant characteristics and adequacy of vitamin B₁₂ intake. In this cross-sectional study, data were collected via an online survey. Demographic and health characteristics of women on a vegan diet were compared with women in the general population (using Australian Bureau of Statistics data). Intake of vitamin B₁₂ was estimated using a FFQ and estimation of supplemental intake. Australia. Participants (n 1530) were women aged 18–44 years who had been on a vegan diet for at least 6 months. While BMI, smoking habits and intakes of fruit and vegetables compared favourably with the general population, 26 % of respondents had estimated intakes of vitamin B₁₂ below recommendations. Analyses of relationships between vitamin B₁₂ intake and participant characteristics revealed that the strongest predictor of intake was supplementation (P < 0·001); however, 25 % had not supplemented with vitamin B₁₂ in the past 3 months. The vitamin B₁₂ intakes of a substantial proportion of Australian women of reproductive age consuming a vegan diet do not meet the recommended intake, which could adversely affect their health, and, if they are pregnant or lactating, that of their infants too. There is a need for further research in this area to identify effective strategies to address this situation.

Vitamin B12 intake of women of reproductive age on a vegan diet in Australia

2020

This study examined the vitamin B12 intake of 1530 women of reproductive age on a vegan diet in Australia, using an online survey which included a food frequency questionnaire and assessment of supplemental intake. Relationships were found between adequacy of intake and participants' characteristics, including knowledge attitudes and beliefs relating to vitamin B12. The limitations of current methodology for assessing vitamin B12 status and of considering supplemental intake as equivalent to intake from food were examined. The information gained from this study provides direction to interventions aimed at ensuring adequacy of vitamin B12 intake in people on plant-based diets.
