Dietary fiber is an essential part of [[human]] [[nutrition]] as it help in many [[digestion|digestive]] and [[nutrition|nutritional]] roles. Also called “roughage,” dietary fiber is a type of [[carbohydrate]] found in mostly plant based [[foods]] such as [[leafy greens]], [[vegetables]] etc and is made up of many sugar molecules linked together. But unlike other carbohydrates (such as starch), dietary fiber is bound together in such a way that it cannot be readily digested in the small intestine.

==Structure and Composition==
* Dietary fiber is made up of multiple sugar molecules linked together. 
* The molecular structure of dietary fiber makes it resistant to digestion in the small intestine, meaning it does not break down into simple sugars like glucose. 
* Instead, dietary fiber travels through the digestive system intact, providing numerous health benefits along the way.

== Types of dietary fiber ==
There are two types of dietary fiber, and most plant foods contain some of each kind: 
* Soluble fiber dissolves in water to form a thick gel-like substance in the stomach. It is broken down by bacteria in the large intestine and provides some calories. 
* Insoluble fiber does not dissolve in water and passes through the gastrointestinal tract relatively intact and, therefore, is not a source of calories.

== Sources of dietary fiber == 
Soluble fiber is found in a variety of foods, including: 
* Beans and peas 
* Fruits 
* Oats (such as oat bran and oatmeal) 
* Nuts and seeds 
* Vegetables Insoluble fiber is found in a variety of foods, including: 
* Fruits 
* Nuts and seeds 
* Vegetables 
* Wheat bran 
* Whole grain foods (such as brown rice and whole grain breads, cereals, and pasta)

== Benefits of dietary fiber ==
* Soluble fiber can interfere with the absorption of dietary fat and cholesterol. 
* This, in turn, can help lower low-density lipoprotein (LDL or “bad”) cholesterol levels in the blood. 
* Soluble fiber also slows digestion and the rate at which carbohydrates and other nutrients are absorbed into the bloodstream. 
* This can help control the level of blood glucose (often referred to as blood sugar) by preventing rapid rises in blood glucose following a meal. 
* Insoluble fiber provides “bulk” for stool formation and speeds up the movement of food and waste through the digestive system, which can help prevent constipation. 
* Both soluble and insoluble fiber make you feel full, which may help you eat less and stay satisfied longer.
====More benefits====
* Supports digestive health: Dietary fiber is essential for digestive health, as it helps to regulate the movement of food through the digestive system and promotes regular bowel movements. This reduces the risk of digestive disorders such as constipation, diverticulitis, and colon cancer.
* Lowers cholesterol levels: Soluble fiber has been shown to reduce total and LDL cholesterol levels, which is beneficial for cardiovascular health.
* Aids in weight management: Dietary fiber helps to promote feelings of fullness and reduces calorie intake, making it a useful tool for weight management.
* Supports gut health: Dietary fiber provides food for the beneficial bacteria in the gut, helping to promote a healthy gut microbiome.
== Recommended amount of fiber ==
The Daily Value for fiber is 25 g per day based on a 2,000 calorie diet — your daily Value may be higher or lower depending on your calorie needs.
== Lack of fiber in diet ==
Most Americans do not get the recommended amount of dietary fiber. Dietary fiber is considered a “nutrient of public health concern” because low intakes are associated with potential health risks.
* Diets higher in dietary fiber promote intestinal regularity and can reduce the risk of developing cardiovascular disease.
