Ultra-processed foods as ingredients of culinary recipes shared on popular Brazilian youtube cooking channels

Social media platforms are readily accessible sources of information about cooking, an activity deemed crucial for the improvement of a population's diet. Previous research focused on the healthiness of the content shared on websites and blogs, but not on social media such as YouTube ®. This paper analysed the healthiness of 823 culinary recipes retrieved from 755 videos shared during a six-month period on ten popular Brazilian YouTube ® cooking channels. Recipes were categorized by type of preparation. To assess recipes' healthiness, ingredients were classified according to the extension and purpose of industrial processing, in order to identify the use of ultra-processed foods. Additionally, a validated framework developed from criteria established in both editions of the Dietary Guidelines for the Brazilian Population was employed. Recipes for cakes and baked goods, puddings, snacks and homemade fast foods, which were among the most frequently posted, contained the lowest proportion of unprocessed/minimally processed ingredients and the highest proportion of ultra-processed ingredients. Recipes containing whole cereals, fruits, legumes, nuts, and seeds were scarce. Results indicate that users should be critical about the quality of recipes shared on YouTube ® videos, also indicating a need for strategies aimed at informing individuals on how to choose healthier recipes or adapt them to become healthier.
