A vegetarian diet can easily meet human dietary protein requirements as long as energy needs are met and a variety of foods are eaten. Vegetarians should obtain protein from a variety of plant sources, including legumes, soy products, grains, nuts and seeds. ⋯ There is no need to consciously combine different plant proteins at each meal as long as a variety of foods are eaten from day to day, because the human body maintains a pool of amino acids which can be used to complement dietary protein. The consumption of plant proteins rather than animal proteins by vegetarians may contribute to their reduced risk of chronic diseases such as diabetes and heart disease.

While intakes of the omega-3 fatty acid α-linolenic acid (ALA) are similar in vegetarians and non-vegetarians, intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are low in vegetarians and virtually absent in vegans. Plasma, blood and tissue levels of EPA and DHA are lower in vegetarians than in non-vegetarians, although the clinical significance of this is unknown. Vegetarians do not exhibit clinical signs of DHA deficiency, but further research is required to ascertain whether levels observed in vegetarians are sufficient to support optimal health. ⋯ However, we suggest that vegetarians double the current adequate intake of ALA if no direct sources of EPA and DHA are consumed. Vegetarians with increased needs or reduced conversion ability may receive some advantage from DHA and EPA supplements derived from microalgae. A supplement of 200-300 mg/day of DHA and EPA is suggested for those with increased needs, such as pregnant and lactating women, and those with reduced conversion ability, such as older people or those who have chronic disease (eg, diabetes).

• Five years on from the establishment of the National Health and Hospitals Reform Commission, it is timely to review the context for reform and some of the actions taken to date, and to highlight remaining areas of concern and priority. • The Commission's final report was released in July 2009 and presented 123 recommendations organised under four reform themes: Taking responsibility: individual and collective action to build good health and wellbeing - by people, families, communities, health professionals, employers, health funders and governments Connecting care: comprehensive care for people over their lifetime Facing inequities: recognise and tackle the causes and impacts of health inequities Driving quality performance: leadership and systems to achieve best use of people, resources and evolving knowledge. • Overall, the Australian Government's response to the Commission's report has been very positive, but challenges remain in some key areas: Financial sustainability and the vertical fiscal imbalance between the federal and state governments Getting the best value from the health dollar by reducing inefficiency and waste and using value-based purchasing across the public and private health sectors National leadership across the system as a whole Getting the right care in the right place at the right time Health is about more than health care - increasing focus on prevention and recognising and tackling the broader social determinants of health.
