Plant-based Consumption across Generations

Closing the Generational Gap: Younger Consumers Are Driving the Consumption of Plant-based Food While Boomers Lag Behind

Since 2021, GlobeScan has partnered with EAT, a science-based global platform for food system transformation, to conduct the Grains of Truth consumer research series. This annual survey, conducted in 31 markets worldwide, aims to delve into consumers’ concerns about the current food system, their attitudes and behaviors toward consuming healthy and sustainable food, and their viewpoints on who should lead the transformation of the food system. 

This study details the significant differences in views between age groups. This year, the research shows that although Baby Boomers are generally more likely to say they frequently eat healthy food, they are less likely to report frequently eating a plant-based diet: only 16 percent of Baby Boomers and older say they eat plant-based food “most” or “all of the time” compared to Gen Z and Millennials, with 27 percent each.  

Most importantly, Gen Z consumers (just like their Gen X counterparts) report an increase in adopting a vegetarian or vegan diet, with a five-point jump since 2021.  


Younger consumers are driving the consumption of vegetarian and vegan food, and they present a significant opportunity for sustainable food brands.

However, it is crucial to consider other cohorts, such as Baby Boomers, who are currently lagging in adopting a vegetarian/vegan diet. The shift from a meat-based to a plant-based diet can only be fully realized with the participation of all age groups if we are to reap the benefits, both in terms of public health and climate change mitigation.
