Fiber volume意思

"Fiber volume" is a term that can be used in various contexts, but it most commonly refers to the volume of dietary fiber consumed. Dietary fiber is a type of carbohydrate that is found in plant-based foods such as fruits, vegetables, whole grains, and legumes. It is an important part of a healthy diet because it can help improve digestion, prevent constipation, lower cholesterol levels, and reduce the risk of certain diseases such as heart disease and type 2 diabetes.

When talking about fiber volume in the context of nutrition, it typically refers to the total amount of fiber in a food or in a person's diet over a certain period of time, such as in a day or a week. The recommended daily intake of dietary fiber varies depending on age and sex, but generally, adults need about 25 to 38 grams of fiber per day.

In materials science, "fiber volume" may refer to the volume fraction of fibers in a composite material. Composite materials are made by combining two or more materials with different properties, such as strength and stiffness, to create a material with improved properties over those of the individual components. For example, fiber-reinforced plastics are composites that use fibers such as glass or carbon to reinforce a plastic matrix, resulting in a material that is both strong and lightweight. The fiber volume in this context would refer to the volume of fibers relative to the total volume of the composite.
