Discussion: Why does the gut flora have a far-reaching effect on the immune system? Is it relevant for patients with autoimmune diseases?

Strengthening the immune system and maintaining a balanced intestinal flora is vital for patients with autoimmune diseases. The gastrointestinal tract is the primary non-sterile internal system, forcing the immune system to fight relentlessly to prevent pathogens' overgrowth. Poor nutrition of processed and industrialized foods significantly affects the liver and kidneys. Bile fluid, a strong chemical base, tends to crystallize and clog the liver and gallbladder; thus, the problem only worsens. Bile flow is critical for maintaining proper gastrointestinal function. It is oily and lubricates the intestines; it also counteracts the high acidity of the food from the stomach, thereby preventing an acidic intestinal environment.
