Nutrient Digestibility

Digestibility of a nutrient is the proportion of a nutrient that enters the body that the body is able to absorb. It depends on several factors, such as food digestibility and completeness of absorption. Digestibility is determined by how well the body can process food, and absorption is how efficiently the body absorbs nutrients from food.

Nutrient absorption can be high or low depending on the type of food. For example, carbohydrates, proteins and fats have different degrees of digestibility. Carbohydrates, such as starch and sugar, are absorbed by the body easily and quickly, while proteins and fats require a longer time to be absorbed.

In addition, digestibility may depend on the state of the body. For example, people with digestive problems may have low absorption of certain nutrients. Other factors such as age, gender, physical activity and diet may also affect absorption.

It is important to understand that digestibility is not the only factor determining nutritional requirements. It also depends on other factors such as physical activity level, age and health status. Therefore, it is important to balance your diet, taking into account not only digestibility, but also other factors.

Nutrient digestibility (from Latin digestio, “digestion”) is a value indicating what proportion of a particular nutrient is absorbed by the body.

Digestibility can be determined either using modeling of the contents of the gastrointestinal tract, which gives a good approximation of reality, or experimentally by analyzing changes in the chemical composition or amount of a substance in the material that has passed through the digestive tract. It can be most accurately determined only by measuring the amount of a substance after passing through the body, but this requires animal or laboratory tests.
