In Japan, a new study emerges among others and concerns the risk of onset of dementia related to fiber intake. Here is the detail.
The dementia it is a type of neurodegenerative disease of the brain typical of old age. A Japanese study correlated the onset of this pathology with fiber intake. They are in fact a fundamental food for our body and every dietician and nutritionist suggests including them in your diet for better health. Fiber is known for its importance to the digestive system and also has cardiovascular benefits as it affects cholesterol.
Evidence has recently emerged in Japan, in which the fiber it would also be important for a healthy brain. The research was published in Nutritional Neuroscience and was conducted by Japanese scholars. It showed that a high-fiber diet is associated with a reduced risk of developing dementia. The study’s author, Professor Kazumasa Yamagishi claimed that dementia is a devastating disease that requires long-term care, so he was interested in carrying out research that suggested that dietary fiber could play an important role.

Dementia and fiber, the Japanese study
The study involved thousands of adults residing in Japan, a study that goes on from 80s. In fact, the participants completed surveys that assessed their diets between 1985 and 1999. People were generally healthy and between the ages of 40 and 64. Then from 1999 to 2020 it was noted whether or not people had developed a form of dementia that required treatment.

Researchers found that the link between fiber intake and dementia is more relevant when it comes to soluble fibers, or those fibers found in foods such as oats and legumes. They are important for the bacteria that live in the gut and for good health. The mechanisms of how dementia and fibers are related are still unknown but great strides have already been made.
