Nutritional and Environmental Diseases

The video explores non-infectious diseases, which are not caused by pathogens and cannot be transmitted. It categorizes them into inherited, nutritional, and environmental diseases. Inherited diseases, like Down syndrome, are genetic and passed from parents to offspring. Nutritional diseases, such as scurvy, result from poor nutrition and are treatable by dietary changes. Environmental diseases, like asbestosis, are caused by environmental factors such as exposure to asbestos. The video concludes by summarizing these categories and their characteristics.
