A Comparative Content Analysis of Vegetarian Food Blogs Written by Registered Dietitians and Non-Registered Dietitians.
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.
