“…Th e prevalence of serologically diagnosed CD in this study was found to be 0.71 % , equating to 1.8 million CD suff erers nationwide, yet up to 80 % were previously unaware of the diagnosis of CD and not taking a GFDwhat this data suggests is that the prevalence of the frequency of utilization of a GFD in American individuals is substantially greater than the prevalence of diagnosed CD. Furthermore, recent work from New Zealand has determined that CD aff ected 1 % of children, yet 5 % reported gluten avoidance ( 39 ). Further validating studies are needed elsewhere to determine the use of GFD among the general public, although it does appear clear that a signifi cant proportion are consuming a GFD in the absence of CD.…”

Historically, it has been reported that patients with undetected celiac disease (CD) may present with irritable bowel syndrome (IBS) type symptoms. This has led to the recommendation by the American College of Gastroenterology Task force that patients presenting with diarrhea predominant IBS type symptoms should be serologically tested for CD. Concurrently speculative media data suggest that the US general public have increased their uptake of a gluten-free diet (GFD) far in excess of the known prevalence of CD. This may suggest that individuals with gastrointestinal symptoms are deriving benefi t from a GFD even if they do not have CD. This has led to the scientifi c community considering the evidence for an emerging concept of non-celiac wheat sensitivity. There is a signifi cant disparity in our views about what this phenomenon may be. There is also confusion about the nomenclature for this entity and indeed whether patients are suffering due to symptoms related to gluten or perhaps other components of wheat, for example fructans. In this month ' s edition of the American Journal of Gastroenterology , we see evidence to support the clinical concept of wheat sensitivity or intolerance. Irrespective of the nomenclature Carroccio provides a clinically applicable approach that may be adopted internationally by clinicians. This offers a new option in our armamentarium when seeing patients with IBS type symptoms.

“…Tanpowpong et al [7] reported that 5 % of children without CD avoid gluten-containing food, and that this dietetic restriction in a different cohort is associated with improvement of non-specific behavioral and gastrointestinal complaints [14]. However, it is unclear how many children reporting gluten avoidance were indeed affected by NCGS, as the vast majority of the children were neither tested for CD nor underwent an intestinal biopsy.…”

“…Paradoxically in US population, more people are aware of NCGS than they are of CD [5]. Nowadays, marketers estimate that 15 to 25 % of North American consumers want gluten-free foods, although doctors estimate that just 1 % have CD [6] although recently published data would suggest this to be an overestimation [7].…”

Aim: The objectives of this study were to: (1) determine the prevalence of the GFD in a New Zealand adult population, (2) investigate the reasons why people are on the GFD and (3) explore what factors limit adherence to the diet.Methods: This was a cross-sectional online survey of 3,000 students and 3,000 staff at the University of Otago, New Zealand, undertaken in July-August 2013. Participants were randomly selected from databases of students and staff at the University of Otago in July 2013. Survey questions included four main sections: demographics, dietary habits, motivating factors and barriers to following a GFD. The analysis compared the variables between students and staff as well as between people on the GFD and those not on the GFD, using a linear regression analysis model. Results:The overall response rate was 35.5% (2123 respondents). The prevalence of people currently on the GFD was 6.1% in this university population, while another 6.2% reported having previously tried the GFD. The prevalence of CD was 1.2%. Feeling unwell when eating food that contains gluten was the main reason for following the GFD in our study population. Poor availability along with cost of gluten-free (GF) foods was the main factors limiting adherence to the GFD. Conclusion:A significant proportion of a New Zealand university population is currently following or has followed a GFD. People follow a GFD for multiple reasons other than medical indications. People with special diets in a university setting appear to have difficulty accessing dietary options.
