Abstract

This purpose of this study was to compare the nutritional content of vegetarian recipes published in food blogs written by registered dietitians (RDs) and by non-registered dietitians (non-RDs). Twelve food blogs written by RDs and 12 written by non-RDs were selected using a systematic approach. For each food blog, 2 vegetarian entrée recipes per season were selected (n = 192 recipes). Descriptive analyses were performed using Fisher’s exact test. Median nutritional values per serving between RDs’ and non-RDs’ recipes were compared using Wilcoxon–Mann–Whitney tests. RDs’ recipes were significantly lower in energy, non-heme iron, vitamin C, and sodium, contained significantly more vitamin D and had a higher protein proportion than non-RDs’ recipes. Disparities were also observed across type of entrée and vegetarian dietary pattern. In conclusion, this study showed that RD and non-RD food bloggers provided vegetarian recipes with few nutritional differences. Whether expanding the comparative analysis between RDs and non-RDs’ blogs targeting different nutrition-related topics would yield different results remains to be investigated.

Résumé

Cette étude visait à comparer la valeur nutritive de recettes végétariennes publiées dans des blogues culinaires tenus par des diététistes (R.D.) vs par des gens ne détenant pas un titre professionnel de diététiste (non-R.D.). Douze blogues culinaires tenus par des R.D. et 12 tenus par des non-R.D. ont été choisis au moyen d’une approche systématique. Dans chaque blogue, 2 recettes végétariennes de plat principal ont été sélectionnées par saison (n = 192 recettes). Des analyses descriptives ont été effectuées à l'aide du test exact de Fisher. Les valeurs nutritives médianes par portion des recettes des R.D. et des non-R.D. ont été comparées au moyen de tests de Wilcoxon–Mann–Whitney. Les recettes des R.D. étaient significativement plus faibles en énergie, en fer non hémique, en vitamine C et en sodium, et contenaient significativement plus de vitamine D ainsi qu’une plus grande proportion de protéines que les recettes des non-R.D. Des disparités ont également été observées entre les types de plats principaux et les modèles alimentaires végétariens. En conclusion, cette étude a montré que les blogueurs, qu’ils soient R.D. ou non, présentaient des recettes végétariennes comportant peu de différences sur le plan nutritionnel. Il reste toutefois à déterminer si les résultats d’analyses comparatives ciblant d’autres sujets relatifs à la nutrition sur les blogues tenus par des R.D. et des non-R.D. contrasteraient avec ceux de cette étude.
