Public health has been described as "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health has many sub-fields, but typically includes the interdisciplinary categories of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, and occupational health are also important areas of public health.
An important way to maintain your personal health is to have a healthy diet. A healthy diet includes a variety of plant-based and animal-based foods that provide nutrients to your body. Such nutrients give you energy and keep your body running. Nutrients help build and strengthen bones, muscles, and tendons and also regulate body processes (i.e. blood pressure). The food guide pyramid is a pyramid-shaped guide of healthy foods divided into sections. Each section shows the recommended intake for each food group (i.e. Protein, Fat, Carbohydrates, and Sugars). Making healthy food choices is important because it can lower your risk of heart disease, developing some types of cancer, and it will contribute to maintaining a healthy weight.

Australian health funds can be either 'for profit' including Bupa and nib; 'mutual' including Australian Unity; or 'non-profit' including GMHBA, HCF and the HBF Health Fund (HBF). Some, such as Police Health, have membership restricted to particular groups, but the majority have open membership. Membership to most health funds is now also available through comparison websites like moneytime, Compare the Market, iSelect Ltd., Choosi, ComparingExpert and YouCompare. These comparison sites operate on a commission-basis by agreement with their participating health funds. The Private Health Insurance Ombudsman also operates a free website which allows consumers to search for and compare private health insurers' products, which includes information on price and level of cover.
The state passed healthcare reform in 2006 in order to greater decrease the uninsured rate among its citizens. The federal Patient Protection and Affordable Care Act (colloquially known as "Obamacare") is largely based on Massachusetts' health reform.
