Eating healthily can be less expensive than the unhealthy diet many Australians currently live on. A study compared the cost of the recommended Australian Dietary Guidelines to an average Australian family buys and eats a fortnight. It found that the healthy diet can save $150 at the checkout a fortnight, or $3,900 a year. The study also highlighted the health benefits of the guidelines, which include eating more fruit and vegetables, wholegrains, lean meats, and dairy products, and avoiding processed foods, sweetened drinks, desserts, and alcohol. The researchers said that diets in fruit and vegetables can protect against high blood pressure, heart disease, stroke, Type 2 diabetes, and some cancers, as well as mood and mental wellbeing. They suggested that families can start making small changes, planning meals with their kids, and trying to make healthy versions of takeaway meals at home.
