Increased intestinal permeability, so called leaky gut, has been linked to food allergies[87] and some food intolerances.[88][89] Research is currently focussing on specific conditions[90][91][92] and effects of certain food constituents.[93][94][95] At present there are a number of ways to limit the increased permeability, but additional studies are required to assess if this approach reduces the prevalence and severity of specific conditions.[89][93]
