Towards more environmentally sustainable diets? Changes in the consumption of beef and plant- and insect-based protein products in consumer groups in Finland.

This study investigated consumers' self-reported past changes and future intentions to change the consumption of beef and alternative, plant- or insect-based protein products. A survey of 18-79-year-old consumers in Finland (N = 1000) was analysed with latent class analysis, and five consumer clusters were identified. The largest cluster (37%) consumed beef, but no alternative protein products; three clusters incorporated alternative protein products in their diets in different ways (in total 55%); and one cluster did not consume beef or alternative proteins (8%). In total 27% of the respondents intended to reduce the consumption of beef in the future, whereas 26% planned to increase the consumption of plant-based and 24% planned to increase the use of insect-based protein products. Multinomial logistic regression indicated that the use of alternative proteins was associated with higher health and sustainability motives, and lower food neophobia. The results suggest that demand for new, more sustainable proteins and protein innovations will grow in the future.
