Dietary fiber does much more than aid bowel movements. It can be considered a prebiotic food. Prebiotics are not actively digested or absorbed, but are used selectively to stimulate the growth of beneficial types of microbes in the gut. These microbes then help digest the food.
Fiber may also affect the immune system. Due to this, inflammation in the body decreases.
It is recommended to take 25-38 grams of protein daily. But this also depends on the person’s age, gender and physical activity level.
Good sources of dietary fiber include whole grains, vegetables, fruits, beans, legumes, seeds and nuts. Many foods contain a mixture of both soluble and insoluble fibers.
Diets low in fiber have been scientifically proven to be associated with gastrointestinal disorders such as irritable bowel syndrome or inflammatory bowel disease.
On the other hand, consuming adequate amounts of fiber also reduces the risk of obesity, heart diseases and death caused by them. There are studies showing improvements in cognitive function when taking certain types of fiber.
But not all fiber is healthy. Additionally, excessive consumption of fiber supplements can cause constipation, bloating, and gas. This is partly due to differences in gut microbiomes between people.
