Diet-related health problems require us to change our food choices rather than emphasise individual nutrients

After almost 4 years of review, in February 2013 the National Health and Medical Research Council released the latest revision of its dietary guidelines for Australians.1 Recognising that people consume foods rather than single nutrients, the new guidelines feature food-based advice, emphasising dietary patterns that are associated with health and wellbeing and are relevant to reducing the risks of obesity and chronic disease.
