This highlights the need for improved medical training to address this critical gap.
A study found that 44% of respondents were open to trying insects, while 27% were willing to include them in their regular diet. Curiosity and perceived health benefits were key motivators, while disgust and fear were major barriers. Presenting insect-based products in a appealing way can help increase acceptance.
Researchers found three types of relational fractures: co-performance, co-learning, and marketplace. Vegans employ strategies such as decoding, decoupling, divesting, and chameleoning to cope with conflicts. These findings are transferable to other contexts, highlighting the need for social skills to navigate moral differences.
