Nutritional Quality of Plant-Based Fish and Seafood Analogs: A Study of the Italian Market.

Among plant-based analogs, fish and seafood analogs (PBFSAs) represent a growing sector. This study analyzed the nutritional quality of PBFSAs in Italy and compared it to their animal-based counterparts. Nutritional declarations, ingredient lists, and claims were collected from PBFSA food labeling. Nutri-Scores of PBSFAs and animal-based counterparts were also determined as nutritional quality indicators. Fifty-one products were collected, with most attributed to tuna, salmon, and cod categories (n = 18, 12, and 14, respectively). Results showed large heterogeneity in nutritional quality, with cod products having higher energy (217 (201-257) kcal/100 g), protein (10.5 (7.9-13.0) g/100 g), and carbohydrate (19.4 (14.2-26.0) g/100 g) levels, while tuna and salmon products had a higher fat content (15.0 (10.0-19.7) and 13.5 (5.0-17.0) g/100 g, respectively). Products with fiber or fat nutrition claims did not necessarily indicate higher fiber or lower fat content, while products with a protein claim had a higher protein content. Most animal-based counterparts, except cod and sturgeon caviar, received an "A" Nutri-Score, and often scored better than the PBSFA due to lower salt content. In conclusion, PBFSAs on the market should not be considered animal product analogs regarding nutritional quality, but drawing definitive conclusions is challenging due to the limited number and high variability of the products. However, these findings provide insights that may improve PBFSA nutritional quality, such as decreasing salt and sugar content, for people trying to incorporate such foods into their diet.
