Brief summary
Several studies have been completed in countries other than Australia comparing urinary iodine concentration and iodine intake in omnivores, vegetarians and vegans. It has been found that plant based diets are lower in iodine in these studies. Dairy is one of the first or second main sources of iodine in the Australian diet, while it is variable depending on geographic location and supplementary feeding practices. Plant milks are currently low in iodine and are subject to fortification restrictions in Australia. The research may help to update fortification guidelines for plant based products. The hypothesis is that the plant based group will have a lower urinary concentration of iodine.
Interventions
This is a cross sectional pilot study including 50 pre-menopausal women, age 18-50. Recruitment will involve 25 vegan and 25 non vegan participants, which may include vegetarians. Participants will be asked to visit the clinical trials facility at the University of South Australia on two separate occasions to provide a spot urine sample as well as complete a diet record using an on-line diet analysis program over 2 days. dietary iodine and selenium intake between vegan and non vegan participant

Comparing urinary iodine concentration between the two groups. Participants are required to complete questionnaires, provide urine samples for urinary iodine concentration testing. Fill out an online dietary application for 2 days. (2 days dietary recording - research food diary application) (2 separate days taking urinary iodine concentration - 2 tests in 2 weeks) (2 further questionnaires (1 each week))
