Abstract Objectives Describe the gluten content of leading U.S. brands of cookies, crackers, hot cereals, ready-to-eat (RTE) cereals, specially formulated bars (e.g., Clif, Luna bars), granola bars, savory snacks, and candies. Methods To address the needs of researcherers examining the role of gluten in gastrointestinal health, gluten was added to a U.S. food and nutrient database. Few foods have been chemically analyzed for their gluten content. Thus, gluten values were assigned to foods based on the assumptions that: 1) foods that do not include any gluten containing grains or their derivatives- wheat, rye or barley may be presumed to contain 0 grams of gluten; and 2) a specified fraction of vegetable protein found in wheat, rye, barley and their derivatives (0.75) may be presumed to be gluten (factor selected based on studies in which gluten content of some gluten containing grains were determined by chemical analysis). Gluten values were assigned to brand name products in the database, thus presenting a unique opportunity to describe the gluten content of brand name products in the U.S. marketplace. For each food category the % of products containing gluten was calculated, and the mean and range in gluten content among gluten containing products were determined. Results Food categories with the highest proportion of products containing gluten were cookies (97.1%), crackers (82.7%), hot cereals (66.0%), and RTE cereals (64.8%). Categories with the lowest proportions were candies (15.7%) and savory snacks (25.0%). The mean gluten content among gluten containing products was highest for hot cereals (2.62 grams/serving), crackers (1.82 grams/serving), RTE cereals (1.76 grams/serving), and savory snacks (1.51 grams/serving). Granola bars and specially formulated bars had the lowest content (0.27 and 0.31 grams/serving respectively). The range in gluten content per serving for gluten containing products was lowest for granola bars (0.002–1.11 grams/serving) and highest for RTE cereals (0.001–7.03 grams/serving). Conclusions There is considerable variation in the gluten content of brand name products in the categories examined in this study. Studies quantifying dietary gluten intake may need to consider using a dietary assessment method that captures product brand. Funding Sources American Gastroenterological Association.

Abstract FFQ are one of the most widely used tools of research into nutritional epidemiology, and many studies have been conducted in several countries using this dietary assessment method. The present study aimed to evaluate the relative validity of FFQ, in comparison with other methods, in assessing dietary intake of children and adolescents, through a systematic review. Four electronic databases (Embase, PubMed, Scopus and Web of Science) found sixty-seven articles, which met the inclusion criteria (healthy children and adolescents from 3 to 18 years of age; journal articles written in English, Spanish and Portuguese between 1988 and March 2019; results showing the comparison between the FFQ with other methods of assessment of dietary intake). The articles were analysed by two independent reviewers. A meta-analysis was conducted using correlation coefficients as estimate effects between the FFQ and the reference standard method. Subgroup analysis and meta-regression were performed to identify the probable source of heterogeneity. In fifty-five of the sixty-seven studies, a single dietary assessment method was used to evaluate the FFQ; nine combined the two methods and three used three reference methods. The most widely used reference method was the 24-h recall, followed by the food record. The overall relative validity of the FFQ to estimate energy, macronutrient, certain micronutrient and certain food item intakes in children and adolescents may be considered weak. The study protocol was registered in PROSPERO under number CRD42016038706.

The relationship between diet and the development of chronic disease still remains a controversial area. One major difficulty is to obtain a valid estimate of habitual pattern and level of food consumption for each individual. There is, in fact, a voluminous and largely negative literature on the validity of dietary assessment methods. In the present paper the utility of the most frequently used dietary assessment method in epidemiological studies is discussed in terms of precision and accuracy.

AbstractObjective:This study aimed to determine the accuracy with which children aged 5 to 7 years were able to report the food eaten at a school lunch.Subjects/setting:Two hundred and three children (103 boys, 100 girls) aged 5–7 years were recruited from three primary schools in Oxford.Design:Trained investigators made observational records of the school dinner and packed lunch intakes of four or five children per session. Children were interviewed within two hours of finishing the lunchtime meal and asked to provide a free recall of their meal. When the child had completed the recall, non-directive prompts were used to assess if the child was able to remember anything else. Foods recalled were classified as matches (recalled food agreed with observation), omissions (failed to report a food observed) or phantoms (recalled food was not observed).Results:The percentage of accurate recall was significantly higher (P<0.01) in children eating packed lunch (mean 70±29%) than in children consuming school dinners (mean 58±27%). This difference may have been due to increased familiarity of foods in packed lunches. Leftovers were not readily reported in this age group. Prompts and cues enhanced recall by all children.Conclusions:This study indicated that there was a wide range in the ability of children aged 5–7 years to recall intake from a packed lunch and/or school dinner. This dietary assessment method is unlikely to be suitable at an individual level. Investigators using dietary recall to estimate food intake in children aged 5–7 years need to be aware of the limitations of this method.
