Biotillgång

Biotillgång, or bioaccessibility, refers to the extent to which a substance can be absorbed and utilized by the body. It is a critical factor in determining the nutritional value of a food or supplement. Bioaccessibility is influenced by several factors, including the chemical form of the substance, the presence of inhibitors or enhancers, and the individual's digestive and metabolic processes.

In the context of minerals, bioaccessibility is often assessed using in vitro digestion models, which simulate the digestive process and measure the amount of mineral that becomes available for absorption. This is important because the form in which a mineral is consumed can significantly affect its absorption. For example, calcium in the form of calcium carbonate is less bioaccessible than calcium citrate.

Biotillgång is also relevant in the field of nutrition and health, as it can impact the efficacy of dietary supplements and the overall nutritional status of an individual. Understanding bioaccessibility can help in designing more effective nutritional interventions and in interpreting the results of nutritional studies.

In summary, biotillgång is a key concept in nutrition and health, referring to the extent to which a substance can be absorbed and utilized by the body. It is influenced by various factors and is crucial in determining the nutritional value of foods and supplements.
