A survey shows that up to one in five people believe they have a problem with gluten, a protein found in wheat, barley and rye.
An intolerance to gluten often causes unpleasant gut symptoms like stomach ache, bloating, gas, indigestion, constipation and diarrhoea.
The best way to overcome gluten intolerance is to ditch the ingredient from your life. However, this can have the unintended consequence of reducing other nutrients in your diet.
