Genetic Information and Dietary Intake Behaviour

This study's primary objective is to determine if providing individuals with personal genetic information impacts dietary intake behaviour. Specifically, the investigators will be examining whether providing dietary advice based on genes that affect the metabolism of or sensitivity to caffeine, vitamin C, sugar and sodium will impact the intake of these dietary components. The study hypothesis is that providing dietary advice based on genetics will impact dietary behaviour to a greater extent than general dietary recommendations.

Treatment and study plan

Dietary advice with genetic information

Other

This group will receive dietary advice for caffeine, vitamin C, sugar and sodium based on genes that affect the metabolism of or sensitivity to caffeine, vitamin C, sugar and sodium.

General dietary recommendations

Other

This group will receive general dietary recommendations from recognized health organizations for caffeine, vitamin C, sugar and sodium, with no genetic information.

Primary outcomes

  1. Change from Baseline in Dietary Intake at 3 months

    Time frame: 3 months

    We will assess dietary intakes of caffeine (mg), vitamin C (mg), sugar (g and % energy) and sodium (mg) using Food Frequency Questionnaires (FFQ). An FFQ will be administered at baseline to determine dietary habits before dietary advice is given to either group (control or intervention). A second FFQ will be administered 3 months after the dietary advice is given, to examine if any changes were made to dietary intake in the short-term.

  2. Change from Baseline in Dietary Intake at 12 months

    Time frame: 12 months

    A third FFQ will be administered 12 months after the dietary advice is given, to examine if any long-term dietary changes were made in intakes of caffeine (mg), vitamin C (mg), sugar (g and % energy) and sodium (mg).
