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.
Genetics, or inherited traits from parents, also play a role in determining the health status of individuals and populations. This can encompass both the predisposition to certain diseases and health conditions, as well as the habits and behaviors individuals develop through the lifestyle of their families. For example, genetics may play a role in the manner in which people cope with stress, either mental, emotional or physical. For example, obesity is a significant problem in the United States that contributes to bad mental health and causes stress in the lives of great numbers of people[32]. (One difficulty is the issue raised by the debate over the relative strengths of genetics and other factors; interactions between genetics and environment may be of particular importance.)
Health, as defined by the World Health Organization (WHO), is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."[1][2] This definition has been subject to controversy, as it may have limited value for implementation.[3][4][5] Health may be defined as the ability to adapt and manage physical, mental and social challenges throughout life.[6]
