Key Terms to Review (45)
Anemia: Anemia is a condition characterized by a reduced number or impaired function of red blood cells, leading to a decrease in the oxygen-carrying capacity of the blood. This can have significant implications for an individual's overall health and wellness, particularly in the context of nursing practice and the management of various medical conditions.
Bioactive Compounds: Bioactive compounds are naturally occurring substances found in foods and plants that have beneficial effects on human health beyond basic nutritional functions. These compounds interact with the body's systems to promote overall well-being and prevent or manage certain diseases.
Bioavailability: Bioavailability refers to the degree and rate at which a substance, such as a nutrient or medication, is absorbed and becomes available for use or storage in the body. It is a crucial concept that connects the consumption of nutrients, minerals, and supplements to their ultimate impact on physiological processes and health outcomes.
