About Our Study
The Effects of Milk and Yogurt Supplementation on Bone Health, Body Composition and Gut Health in Canadian Young Adults: A Randomized Controlled Trial aims to assess the impact of consumption of fermented (like yogurt) and non-fermented dairy products (like milk) on:
- bone health and the development of osteoporosis (a condition characterized by loss of bone mass and tissues making bones weak and more likely to break)
- body composition (such as percentage of fat mass and lean mass) and the development of obesity (a condition characterized by extra accumulation of body fat)
- on gut microbiomes (the bacteria inside our intestine, which facilitate different functions inside our body like protection from infections and other diseases).

What to Expect
The study will take place over the course of two years.
Your dairy pick up, if you are in the milk or yogurt groups, will be every two weeks and you can book a time that is convenient for you on this page.
After the intake interview you will be contacted via email four times for remotely administered questionnaires. During these times we will also interview you about your diet. You will also be asked to attend three sessions in person for sampling and measurements. Each of these sessions is expected to take approximately 2 hours. The first in person session may be a bit longer and take approximately 2 and a half hours. We will do our best to make you comfortable and that no time is wasted during the process. This page contains premeasurement instructions.
