The human gut contains a large number of bacteria. Most of these bacteria are beneficial and helpful with food digestion and with limiting growth of harmful bacteria and yeast.

Some children with autism have low levels of beneficial bacteria and high levels of harmful bacteria and yeast. That’s were probiotics come in.

Probiotics do two things that significantly can benefit an autistic person:

  1. They increase the level of beneficial bacteria in the intestinal tract at the expense of undesirable and pathogenic bacteria by a process called competitive exclusion. In other words, the good bacteria compete for the space where the bad bacteria are and win.
  2. They improve the integrity of the soft-lining or mucosal surface of the intestinal tract which reduces the harmful effects of incompletely digested foods and toxins.

When the intestinal tract is healthy, bowel movements are normal and predictable. And when intestinal surfaces are colonized with probiotics, it is difficult for pathogenic microorganisms to infect those surfaces. Then the intestinal surfaces can begin to improve an heal.

The small intestine’s gatekeepers keep incompletely digested foods from entering the bloodstream. But when they are damaged or inflamed, leaky gut results and undigested proteins(like those from wheat gluten and milk casein) pass into the bloodstream and cause a complex of reactions, none of them good.
