Final answer:
The statement that psyllium may be helpful in treating diarrhea because it reduces stool liquidity is true, as psyllium is a soluble fiber that thickens fecal matter and allows for better water absorption in the intestines.
Step-by-step explanation:
The assertion that psyllium may be helpful in the treatment of diarrhea because it reduces the liquidity of the stool is true. Psyllium is a form of soluble fiber that can help regulate bowel movements. Viscous fibers such as psyllium work by thickening the fecal mass, which can help provide relief from diarrhea. This is because, in cases of diarrhea, waste matter moves too quickly through the intestines, leading to insufficient water absorption. Adding soluble fiber like psyllium slows down this process, allowing for more water to be absorbed and thus reducing the liquidity of stools.
In addition to aiding with diarrhea, psyllium and other viscous fibers can be part of an overall dietary plan for managing irritable bowel syndrome (IBS) by helping modify food choices and bowel habits. Furthermore, fermentable fibers like inulin are beneficial for the health of gut microbiota and may help in relieving inflammatory conditions of the bowel.
