Discussion
No prior randomized controlled trials demonstrating that the entity of “gluten intolerance”
does actually exist
This study supports the existence of non-celiac gluten sensitivity based on the following symptoms:
Bloating
Dissatisfaction with stool consistency
Abdominal pain
Tiredness

Future studies
Gluten may have the following deleterious effects in non-celiac patients:
Increase fermentation, and thus, distension
Increase cholinergic activation, and thus, increased smooth muscle contractility
Increase enteric NS stimulation by gluten digestion creating neurally active peptides
Symptoms may not be related to gliadin proteins of gluten

Novak Djokavic claims his energy improved on gluten-
free diet and coincided with his winning streak
“A gluten-free diet can have implications far beyond the physical, especially in tennis, which taxes the mind like few other sports.”
