A high fiber drink is a beverage intended for use as a nutritional supplement and sometimes as a food item. While some of these drinks come premixed and ready to drink, others come as powders that need preparation. Dietary fiber is desired in a human diet for a variety of reasons, including relieving constipation and aiding weight loss. High fiber beverages are manufactured to meet this dietary need for fiber quickly without ingesting large amounts of foods containing fiber.
There are varying recommended daily dosages of fiber, most above 20 grams per day. People who eat mainly processed foods and not a balanced diet will often end up eating much less than this amount. A high fiber drink can supplement an unhealthy diet, but it is often thought to be less successful than eating fiber in foods. This could be due to a general dietary trend towards eating unhealthy food on the part of the consumer, or because the concentrated fiber found in a high fiber drink is less effective by its nature. Still, natural fibers in foods are thought to digest better than those taken as an independent supplement.
Dietary fiber is divided into two types: soluble fiber and insoluble fiber. Soluble fiber forms a gel when combined with water and is fermented by bacteria during digestion. Insoluble fiber passes through the digestive tract relatively unchanged and absorbs water. These fiber types aid digestion and change how nutrients are absorbed in the body. Both types of fiber should be present in a healthy diet, and both are available as supplements in high fiber beverages.
The dosage and type of fiber available in a high fiber drink vary depending on the brand. Many fiber drinks come as powders, and adding more powder to the liquid can change the amount of fiber consumed per drink. Fiber drinks can contain fiber from several sources, such as phyllium or wheat bran. How the consumer uses the product determines how much and what kind of fiber is generally contained in these types of drinks.
While many high fiber drink companies boast the products' ability to dissolve clearly and tastelessly in water, high fiber drink mixes are also available flavored. When the drink comes prepared, it is available in a variety of flavors and textures. As a powder, it can be used in many different drinks, such as fruit smoothies and juices. Many brands offer drink recipes along with their product, which can inform consumers of different ways to use the fiber drink mix.
