Dietary exposure refers to the amount and frequency of consumption of specific foods or nutrients by an individual. It is a measure of how much of a particular substance, such as vitamins, minerals, or other nutrients, enters the body through food intake rather than supplements or medications. Dietary exposure can be influenced by factors such as age, gender, lifestyle habits and cultural practices that affect food choices. It is an important consideration in public health efforts to promote healthy eating patterns and reduce the risk of chronic diseases related to diet.
