Are Insect-Based Foods Healthy? An Evaluation of the Products Sold in European E-Commerce

Over the past few years, edible insects have been recognised as potential "new" food sources in Western countries due to their sustainability and adaptability in the food production sector. To determine the distribution in Europe of insect-based food producers within each country, as well as the number and types of products, data from e-commerce were collected and analysed. The FoodEx2 classification was used to categorise the products. Data about the nutritional composition were recorded and the Recommended Daily Allowance (RDA) was calculated. As a result, 523 products offered by fifty-three companies located in 17 countries of Europe were found. The predominant market was based in Western Europe (55.8%), and 24 insect species were sold. Notably, four species were the most representative: Tenebrio molitor (182 products), followed by Acheta domesticus (140), Alphitobius diaperinus (54), and Locusta migratoria (34). Other species were present in lower quantities. The main commercial categories of insect-based food present in the European e-commerce were snacks, chocolate, and similar products. The results emphasise the potential benefits of incorporating insect-based food into the daily diet in terms of protein, energy, and fat intake. The RDA of the different products highlighted the importance of insects as a nutritional ingredient.
