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."[51] 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.

Natural health care products are currently regulated under the Natural Health Product Regulations, under the authority of the Food and Drugs Act.[3] The regulations address the sale of natural health products, manufacture, packaging, labelling and importation for sale of natural health products, the distribution of natural health products, and the storage of natural health products.[4] Under the regulations, all natural health products require a Natural Product Number (NPN), analogous to the Drug Identification Numbers (DINs) used to identify and monitor drugs in Canada.


Many teens suffer from mental health issues in response to the pressures of society and social problems they encounter. Some of the key mental health issues seen in teens are: depression, eating disorders, and drug abuse.

Mental health can be treated and be attentive to teens' behavior.[40]
Smoking is one of the worst things you can do for your health. Secondhand smoke is also very dangerous. Nearly 7,300 nonsmoking Americans die from lung cancer caused by secondhand smoke every year, reports the Centers for Disease Control and Prevention (CDC). Smoking and secondhand smoke exposure can also cause other health conditions, such as chronic obstructive pulmonary disease (COPD), emphysema, and heart disease. They also raise your risk of developing many types of cancer.
In the first decade of the 21st century, the conceptualization of health as an ability opened the door for self-assessments to become the main indicators to judge the performance of efforts aimed at improving human health[16]. It also created the opportunity for every person to feel healthy, even in the presence of multiple chronic diseases, or a terminal condition, and for the re-examination of determinants of health, away from the traditional approach that focuses on the reduction of the prevalence of diseases[17].

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.[43]

An increasing number of studies and reports from different organizations and contexts examine the linkages between health and different factors, including lifestyles, environments, health care organization and health policy, one specific health policy brought into many countries in recent years was the introduction of the sugar tax. Beverage taxes came into light with increasing concerns about obesity, particularly among youth. Sugar-sweetened beverages have become a target of anti-obesity initiatives with increasing evidence of their link to obesity.[22]– such as the 1974 Lalonde report from Canada;[21] the Alameda County Study in California;[23] and the series of World Health Reports of the World Health Organization, which focuses on global health issues including access to health care and improving public health outcomes, especially in developing countries.[24]
