vezelbron

Vezelbron is a Dutch term that can refer to a source of dietary fiber or, in the field of fiber optics, to a light source used for optical fibers. In everyday Dutch usage, the nutritional meaning is the most common, but the term can arise in technical contexts as well.

Dietary fiber, or vezel in nutrition, consists of plant-based carbohydrates that humans cannot fully digest. It is categorized as soluble or insoluble, depending on its reaction in water. Soluble fibers, such as pectins and beta-glucans, can slow digestion and help regulate blood cholesterol and glucose levels. Insoluble fibers, including cellulose and lignin, add bulk to stool and support bowel regularity. Vezelbronnen include fruits, vegetables, whole grains, legumes, nuts, and seeds. A diet rich in fiber is associated with reduced risk of certain conditions, including constipation, colorectal issues, and some cardiometabolic diseases. Daily intake recommendations vary by country, but are generally around 25–30 grams or more for adults, with higher targets for some populations.

In fiber optics, a vezelbron refers to a device that emits light used to illuminate an optical fibre. Common sources are light-emitting diodes and laser diodes, sometimes broadened by supercontinuum or broadband sources for specialized applications. The choice of source depends on factors such as wavelength, optical power, coherence, and system requirements for communication, sensing, or imaging.

Because the term spans disciplines, the meaning of vezelbron is determined by context. In Dutch science and industry, it is translated as fiber source and applied to both dietary fiber contexts and technical fiber-optic technology.
