Participants in this case-control study of youth with T1D+CD (n\u2009=\u200910) and T1D only (n\u2009=\u20097) wore blinded continuous glucose monitoring systems for six days. Blood glucose levels (BGLs) were compared between groups for each meal, including pre-meal, peak, 2-hour postprandial and time-to-peak. Participants consumed a test-breakfast of GF cereal and milk for three days and kept weighed food diaries; nutrient intake was analyzed and compared to national recommendations. Youth with T1D+CD had shorter time-to-peak BGL (77 vs 89\u2009mins,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.03), higher peak (9.3 vs 7.3\u2009mmol\/L,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.001) and higher postprandial BGLs than T1D (8.4 vs 7.0\u2009mmol\/L,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.01), despite similar pre-meal BGLs (9.2 vs 8.6\u2009mmol\/L,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.28). Regarding test breakfast, greater pre and post-meal BGL difference correlated with longer CD duration (R\u2009=\u20090.53,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.01). Total energy and macronutrient intake didn\u2019t differ between groups; however the majority of participants collectively had inadequate intake of calcium (76%), folate (71%) and fiber (53%), with excessive saturated fat (12%) and sodium (&gt;2,000\u2009mg\/day). The GFD is associated with greater glycemic excursions and inadequate nutritional intake in youth with T1D+CD. Clinical management should address both glycemic variability and dietary quality.\n                  <\/jats:p>","DOI":"10.1038\/srep45286","type":"journal-article","created":{"date-parts":[[2017,3,24]],"date-time":"2017-03-24T06:13:45Z","timestamp":1490336025000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Greater postprandial glucose excursions and inadequate nutrient intake in youth with type 1 diabetes and celiac disease"],"prefix":"10.1038","volume":"7","author":[{"given":"Anna","family":"Pham-Short","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim C","family":"Donaghue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey","family":"Ambler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Garnett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria E.","family":"Craig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,3,24]]},"reference":[{"key":"BFsrep45286_CR1","doi-asserted-by":"publisher","first-page":"359","DOI":"10.1111\/j.1365-277X.2009.00970.x","volume":"22","author":"AR Lee","year":"2009","unstructured":"Lee, A.
