What are essential nutrients known for?

Essential nutrients are known for their bioavailability, which refers to the degree and rate at which the nutrients are absorbed and utilized by the body after ingestion. Bioavailability is crucial because even if food contains essential nutrients, they must be effectively absorbed for the body to benefit from them. For instance, some vitamins and minerals may have varying levels of bioavailability depending on the food sources and the presence of other compounds that can either enhance or inhibit absorption.

Understanding bioavailability is vital, especially in nutritional science, as it highlights the importance of food sources not just providing essential nutrients in theory but also ensuring that these nutrients can be adequately absorbed and utilized by the body's systems. This concept underscores why certain dietary selections can have a significant impact on overall health and nutrient status.
