The food and beverages people consume (their diet) play an important role in their overall health and wellbeing. Food provides energy, nutrients and other components that, if consumed in insufficient or excess amounts, can result in ill health. A healthy diet helps to prevent and manage health risk factors such as overweight and obesity, high blood pressure and high blood cholesterol, as well as associated chronic conditions, including type 2 diabetes, cardiovascular disease and some forms of cancer (NHMRC 2013). Diet-related chronic conditions are among the leading causes of death and disability in Australia.
The Australian Dietary Guidelines provide evidence-based advice on healthy eating habits to promote overall health and wellbeing, reduce the risk of diet-related disease and protect against chronic conditions (NHMRC 2013). They recommend that Australians eat a wide variety of nutritious foods from the 5 food groups every day:
Discretionary foods are foods and drinks that aren’t needed for a healthy diet and don’t fit into the 5 food groups. They are high in energy, saturated fat, added sugars, added salt and/or alcohol and low in fibre. The Australian Dietary Guidelines recommend that their consumption should be limited.
The Australian Dietary Guidelines also provide advice on the number of serves of each food group that Australians should eat each day. Different amounts are recommended for people of different ages, sex, life stages, height and physical activity level.
This page presents the latest nationally available data to report the extent to which Australians are meeting the recommended guidelines.
See Australian Dietary Guidelines.
Data for 2020–21 are based on information self-reported by the participants of the Australian Bureau of Statistics (ABS) 2020–21 National Health Survey (NHS).
Previous versions of the NHS have primarily been administered by trained ABS interviewers and were conducted face-to-face. The 2020–21 NHS was conducted during the COVID-19 pandemic. To maintain the safety of survey respondents and ABS Interviewers, the survey was collected via online, self-completed forms.
Non-response is usually reduced through interviewer follow-up of households who have not responded. As this was not possible during lockdown periods, there were lower response rates than previous NHS cycles, which impacted sample representativeness for some sub-populations.
Additionally, the impact of COVID-19 and lockdowns might also have had direct or indirect impacts on people’s usual behaviour over the 2020–21 period.
Due to these changes, comparisons with previous diet data over time are not recommended.
Based on self-reported data from the 2020–21 NHS, for Australian adults aged 18 years and over:
This page includes dietary information about the Australian population from 2 surveys:
There are strengths of, and limitations to, the information from each survey – while the 2011–12 information is more comprehensive, the 2017–18 information is more recent. Because of this, information from both surveys is included on this page. However, because of the different methods used in the surveys, the results from the 2 surveys should not be compared with each other.
Data from both 24-hour dietary recalls and short survey questions are also subject to various biases. For example, data collected from nutrition surveys are subject to potential under-reporting of food intake, due to:
In 2011–12, most Australians didn’t consume the recommended number of serves from the 5 food groups (ABS 2017; Table 1).
Vegetables and legumes/beans
Grain (cereal) foods
Lean meat and poultry, fish, eggs, nuts and seeds and legumes/beans
Milk, yoghurt, cheese and alternatives

In 2017–18, most Australians didn’t consume the recommended number of serves of vegetables (ABS 2018). The proportion not meeting the recommendation was similar for boys (95%) and girls (93%) aged 2–17, and higher for men (96%) than for women (89%).
However, the proportion of Australians consuming the recommended number of serves of fruit in 2017–18 (ABS 2018) was higher than the proportion meeting the recommendation for vegetables. The proportion not meeting the recommendation was higher for boys (30%) than for girls (24%) aged 2–17, and higher for men (53%) than for women (44%).
More than one-third (35%) of total energy consumed in 2011–12 was from discretionary foods (ABS 2014). The percentage of total energy consumed from discretionary foods was:
Sugar sweetened drinks are a discretionary food. In the NHS 2017–18, the frequency and amount of soft drink, cordials, sports drinks, and caffeinated energy drinks consumed was collected. Fruit or vegetable juices, flavoured milk, coffee, tea and alcoholic beverages were excluded from the scope of the survey (ABS 2018).
Before 2011–12, the last national nutrition survey of children and adults was conducted in 1995. Under-reporting of food intake is estimated to have increased from 1995 to 2011–12, so comparisons between the 2 surveys are based on serves per 10,000 kilojoules rather than reported daily intake (ABS 2017).
Between 1995 and 2011–12, the estimated number of serves per 10,000 kilojoules consumed:
Burden of disease refers to the quantified impact of living with and dying prematurely from a disease or injury.
Burden of disease analysis estimates the contribution of various risk factors to disease burden. In 2018, 5.4% of the total burden of disease in Australia was attributable to dietary risks (such as a diet low in wholegrains and fruit) (AIHW 2021). Dietary risks were the third leading risk factor contributing to the total burden of disease, after tobacco use and overweight and obesity.
About 50% of coronary heart disease total burden and 26% of bowel cancer burden, type 2 diabetes burden and stroke burden were attributable to dietary risks (AIHW 2021). See Burden of disease.
See Determinants of health for Indigenous Australians for information on diet among Aboriginal and Torres Strait Islander people.
In 2017–18, after adjusting for age differences, a greater proportion of Australians aged 18 and over living in Outer regional and remote areas (53%) did not meet the daily fruit recommendation compared with those living in Major cities (48%) (Figure 1). The proportions not eating the vegetable recommendation were similar for adults living in Outer regional and remote areas (92%) and those living in Major cities (93%) (AIHW analysis of ABS 2019a).
In 2017–18, after adjusting for age differences , Australians aged 18 and over living in Outer regional and remote areas were more likely to consume sugar sweetened drinks daily (14%) than those living in Major cities (8.3%) (AIHW analysis of ABS 2019a).
In 2017–18, after adjusting for age differences, Australians aged 18 and over living in the lowest socioeconomic areas were less likely to meet the fruit and vegetable recommendations than those living in the highest socioeconomic areas, although the differences were not large:
Australian adults living in the lowest socioeconomic areas were 3 times as likely to drink sugar sweetened drinks daily (15%) as those living in the highest socioeconomic areas (4.4%) in 2017–18, after adjusting for age differences (AIHW analysis of ABS 2019a).
This chart shows that the proportion of adults who did not meet the vegetable recommendation was similar across remoteness areas and socioeconomic areas, ranging from 91% to 94% in all remoteness areas included (Major cities, Inner regional and Outer regional) and from 92% to 94% in all socioeconomic areas.
Data are highlighting how public health measures put in place during the early stages of COVID-19 (for example, quarantine, the closure of non-essential services and restrictions on venue capacity) have impacted Australians’ dietary habits.
Opportunity-induced eating and coping with negative emotions (such as stress) might also have an impact on unhealthy snacking behaviour (Verhoeven et al. 2015).
Data from the ABS Household Impacts of COVID-19 Survey showed that:
