Plant-Based Meat Alternatives on the Island of Ireland: Changes in the Market and Comparisons with Conventional Meat.

The plant-based meat alternative (PBMA) market and consumer base on the island of Ireland (IOI) has grown rapidly in recent years. Therefore, this study compared the changes in PBMAs available on the IOI over time and the nutritional profiles of PBMAs with meat counterparts. Three online audits of PBMAs available in Tesco's and Sainsbury's in 2021/2022, 2022/2023 and 2023/2024 were conducted. All on-pack information was extracted and analysed using descriptive statistics to identify trends over time. The nutritional content of selected categories of PBMAs identified in the 2023/2024 audit was compared to similar categories of meat using independent samples t-tests or Mann-Whitney-U tests. The number of PBMAs available on the IOI has increased over time (n = 350, n = 321 and n = 398), with a trend in slight improvements in A-scores observed for most categories. Compared to meat, PBMAs had significantly lower total and saturated fat contents and higher carbohydrate, fibre and sugar contents across most categories. The increase in PBMAs over time suggests that the development of new products is ongoing. However, the higher salt contents of PBMAs compared to meat in some categories and only slight improvements in A-scores suggest that focus should be redirected to product reformulation and refinement to improve the nutritional quality of PBMAs.
