A study published in the journal Alimentary Pharmacology and
Therapeutics titled, "Randomised clinical trial: gluten may cause
depression in subjects with non-coeliac gluten sensitivity - an exploratory
clinical study," revealed that gluten consumption significantly increases
the risk of depression.
The doubled-blind cross over study consisted of twenty-two
subjects (24-62 years, five male) with irritable bowel syndrome who tested
negative for celiac disease and whose condition was symptomatically controlled
on a gluten free diet.
The participants randomly received one of three dietary
challenges for 3 days, followed by a minimum 3-day washout before crossing over
to the next diet. Their gluten free diet was challenged with either gluten (16
g/day), whey (16 g/day) or not supplemented at all (placebo).
The study concluded:
"Short-term exposure to gluten specifically induced
current feelings of depression with no effect on other indices or on emotional
disposition. Gluten-specific induction of gastrointestinal symptoms was not
identified. Such findings might explain why patients with non-coeliac gluten
sensitivity feel better on a gluten-free diet despite the continuation of
gastrointestinal symptoms."
In another 2012 study published in the journal of Psychosomatic
Research titled, "Reduced quality of life in coeliac disease is more
strongly associated with depression than gastrointestinal symptoms," found
that even in classical celiac disease patients, it was not the bloating,
diarrhea and multitudinous gastrointestinal problems which caused the most
suffering, rather, it was their declining quality of life – particularly
depression– that they identified to be causing most of their suffering.
