A recent study (ID Croall, et al. Gastroenterol 2019; 157: 881-3) provides additional data indicating that a gluten-free diet does not confer health benefits to healthy individuals.
A double-blind randomized placebo 2-week trial with 30 healthy adults divided subjects into two groups –some received flour sachets to consume with organic gluten (14 g) and some received a gluten-free blend (rice, potato, tapioca, maize, buckwheat flour). Both groups were instructed to take their flour sachets twice a day along with a gluten-free diet (GFD).
Key finding: The group receiving gluten did not experience any increase in gastrointestinal symptoms or fatigue compared to the placebo group.
My take: While this study lasted only 2 weeks and had a small sample size, nevertheless, it adds to the literature indicating that a GFD is unlikely to be beneficial in otherwise healthy individuals. Those who stick with a GFD should seek the help of a well-qualified dietician.
