Bionutrition: The study of the affect of genetics on health
Nutritional Genomics is the study of how foods affect our genes and how individual genetic differences can affect the way we respond to nutrients (and other naturally occurring compounds) in the foods we eat. Under certain circumstances and in some individuals, diet can be a serious risk factor for various diseases. Genetics affect our chances of having several common illnesses like heart disease, asthma, and diabetes. This is called genetic disposition. Diseases like sickle cell anemia, HIV, and some cardiovascular conditions can cause health problems to a person even if they are leading a perfectly healthy lifestyle. Genes can also affect nutrient absorption or the body’s processing and metabolization of food. Conditions like food allergies and food intolerances, such as lactose intolerance, come about from genetic protein deficiencies or inhibitors.
Bionutrition: The Study of The affect of Environment on Health
Nutrition also involves the study of how environmental factors affects a person’s health. Environmental factors include anything from location, food availability, access to medical facilities, and the amount of stress your environment produces. Adequate food security requires the availability of physical supplies of food as well as household access to such supplies either through production, purchase in the market or other means. But, to guarantee nutrition security, food supplies need to meet the specific nutrient requirements of individuals. Major environmental concerns of nutrition are food insecurity, poverty, food deserts, which cause health disparities. Bionutritionists help study these concerns to create equitable conditions for people, regardless of their environment, through programs and assistance usually provided by the government.
