Non-core foods are discouraged in favour of core foods in
dietary guidelines. Australian data indicates that
consumption of non-core foods and drinks, or ‘extra’
foods, exceeds 20% of energy, the recommended limit for
the healthy population. While energy-dense, nutrient poor
choices are associated with excessive energy intake and
weight, we found that trial participants who reported
consuming greater amounts of non-core foods and drinks
at baseline, lost more weight at 3 months than those
consuming foods closer to guideline recommended foods.
However, more detail about the types of non-core foods is
required to give effective dietary advice.
