Social media is used daily by most Australians and there is a plethora of content online about food and nutrition, including on the platform Instagram(1). Among nutrition-related Instagram posts, the provision of recipes is common(1). Australians have reported that they use social media to source recipes and meal ideas(2), however, little is known about the healthfulness of recipes published on social media. Therefore, this study examined the nutrient and food group composition of recipes published by influential Australian Instagram accounts. A list of the top 1000 Australian health influencers was initially screened, and furthered via snowballing, to identify Instagram accounts with ≥100,000 followers who regularly posted a sufficient amount (25%+ within 1 month) of relevant content. All posts (September 2020-2021) for each account were downloaded and screened to identify nutrition-related posts, resulting in a sample of 10,964, (described qualitatively elsewhere(1)). A random subsample of posts (n = 1,199) was screened to identify recipes. Recipes were classified based on the type of meal and analysed in Foodworks to determine the amount of key nutrients and food groups per serve of each recipe. Statistical analysis was undertaken in Stata. In total, 119 recipes were included (n = 30 breakfast, n = 33 lunch/dinner, n = 23 snacks, n = 33 desserts and n = 11 beverages). Per serve, recipes had a median of 1441 ± 1572 kilojoules, 9.0 ± 21.4 grams of protein, 14.6 ± 18.7 grams of fat, 3.7 ± 7.2 grams of saturated fat, 32.5 ± 43.2 grams of carbohydrates, 3.9 ± 9.1 grams of added sugar, 4.9 ± 7.9 grams of fibre and 224.9 ± 446.3 milligrams of sodium. Overall, 46 (39%) recipes contained vegetables, 54 (45%) fruit, 68 (57%) grains, 32 (27%) wholegrains, 85 (71%) meat or meat alternatives, and 40 (34%) milk, cheese, yoghurt or alternatives. On average vegetable, wholegrain and meat/meat alternative content was highest per serve for lunch/dinner recipes (1.23, 1.40 and 0.64 serves, respectively), and fruit and dairy were highest per serve for beverages (1.83 and 0.56 serves, respectively). Recipes published by popular Australian Instagram accounts tended to be low in saturated fat, added sugars and contain moderate amounts of sodium and fibre per serve. Less than half the recipes analysed contained vegetables and the amount of vegetables per serve tended to be low. Overall, there was a large amount of variation in the energy density, nutrient and core food group composition of recipes and social media users should be selective about which recipes from Instagram they choose to prepare.
