Colon health: A diet rich in fiber is associated with a lower risk of developing colorectal cancer. Gut microbiome support: Fiber acts as a prebiotic, promoting the growth of healthy bacteria in ...
Researchers found that when gut bacteria break down plant fiber, they produce two compounds that act on genes to help prevent the growth of cancers. The study is published in Nature Metabolism.
Studies show that thanks to these and other compounds, asparagus spears can promote the growth of certain beneficial gut bacteria, including lactobacilli and bifidobacteria.
Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
Fiber provides bulk to the intestinal contents, and insoluble fiber facilitates peristalsis – the rhythmic muscular contractions of the intestines which move contents along the digestive tract. Some soluble and insoluble fibers produce a solution of high viscosity ; this is essentially a gel, which slows the movement of food through the ...
The high density of bacteria in the colon (about 10 12 per ml.) that are subject to dysbiosis compared to the relatively low density in the small intestine (about 10 2 per ml.) may account for the greater than 10-fold higher incidence of cancer in the colon compared to the small intestine.
The less complicated, the better, and do your best to steer clear of products with added sugar. Soluble vs. insoluble fiber There are two main types of fiber: insoluble and soluble fiber.
Fibre supplements (also spelled fiber supplements) are considered to be a form of a subgroup of functional dietary fibre, and in the United States are defined by the Institute of Medicine (IOM). According to the IOM, functional fibre "consists of isolated, non-digestible carbohydrates that have beneficial physiological effects in humans".
