Mueslis can be packed full of healthy goodness or full of hidden fat and energy. Hannah Blamey sorts the best from the worst.

Misunderstandings are rife when it comes to muesli, says Kate Deppeler, a spokesperson for the Dietitian's Association of Australia.

While muesli is often packed full of healthy goodness, muesli types vary widely in fat and energy content, with some outstripping a burger for fat content, so it pays to practise due diligence before assuming that bowl full is doing you good. Portion size can be an issue, as muesli is often more energy dense (i.e. more calories per spoonful) than other cereals.
