As with anything, and I would use the example of tobacco control, it's a multi-pronged approach that works.
Yes, public awareness and public education are important, and that's an important starting point. As well, we have to make sure that the environment we live in makes the healthy choice the easy choice, so price is important. You need to have affordable foods and you have to ensure that the unhealthy foods are not as affordable. With regard to the difference in the price between milk and sugary drinks, especially in northern communities there's a huge disparity, so we have to improve that.
Affordability is important. Accessibility of healthy food, accessibility of healthy living and health-promoting infrastructure, as I just mentioned, are all important. There are a number of things we have to do, but basically the easiest way is to use public policy to change our environment.
Another example, which has been raised by the government and on which a commitment has been made, is to put restrictions on the marketing of unhealthy foods and beverages to kids. That's another example that can improve health and improve heart disease and stroke in the long term.
