Biobehavioral Factors in Health and Disease - Health and Behavior - NCBI BookshelfNCBI Bookshelf. Research into the bidirectional and multilevel relationships between behavior and health has been aided by technology and by conceptual advances in the behavioral, biological, and medical sciences. Our understanding of the interactions between brain function and behavior has been enriched by advances in behavioral neurobiology, neuroscience, and neuroendocrinology from molecular mechanisms to psychological systems. Real-time imaging of the living human brain during different behavioral states has promoted our understanding of the links between human behavior and basic neurochemical processes or specific neuroanatomic pathways. Common availability of monoclonal antibodies, routine production of genetically altered animals, and new understanding of the genetic code have contributed to exploration of how genetics interacts with development and early experiences to influence both vulnerability to disease and resistance to age-related decline.

Nutritional disease , any of the nutrient-related diseases and conditions that cause illness in humans. They may include deficiencies or excesses in the diet, obesity and eating disorders , and chronic diseases such as cardiovascular disease , hypertension , cancer , and diabetes mellitus. Nutritional diseases also include developmental abnormalities that can be prevented by diet, hereditary metabolic disorders that respond to dietary treatment , the interaction of foods and nutrients with drugs , food allergies and intolerances, and potential hazards in the food supply. All of these categories are described in this article. For a discussion of essential nutrients , dietary recommendations, and human nutritional needs and concerns throughout the life cycle, see nutrition, human. Although the so-called diseases of civilization—for example, heart disease , stroke , cancer, and diabetes—will be the focus of this article, the most significant nutrition-related disease is chronic undernutrition, which plagues more than million people worldwide. Undernutrition is a condition in which there is insufficient food to meet energy needs; its main characteristics include weight loss, failure to thrive, and wasting of body fat and muscle.
A disease is a particular abnormal condition that negatively affects the structure or function of part or all of an organism, and that is not due to any external injury. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency , hypersensitivity , allergies and autoimmune disorders. In humans, disease is often used more broadly to refer to any condition that causes pain , dysfunction , distress , social problems , or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries , disabilities , disorders , syndromes , infections , isolated symptoms , deviant behaviors , and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases can affect people not only physically, but also mentally, as contracting and living with a disease can alter the affected person's perspective on life. Death due to disease is called death by natural causes.
