Not all plant-based diets protect your heart—some may harm it
A new study has revealed that not all plant-based diets benefit heart health equally. Research published in The Lancet Regional Health - Europe found that some plant-focused eating patterns may raise cardiovascular disease risk by 40%. The findings highlight how food quality and processing play a crucial role in long-term health outcomes.
The research, led by Clémentine Prioux and colleagues, tracked 63,835 French adults over an average of 9.1 years. Participants were part of the NutriNet-Santé cohort, with dietary data collected between 2009 and 2018. The study, published in December 2025, compared cardiovascular risks across different plant-based diets.
The study confirms that plant-based eating can support heart health—but only when based on whole, minimally processed foods. Ultra-processed alternatives, even with plant-based labels, may increase cardiovascular risks. These results provide clearer guidance on how dietary choices directly impact long-term well-being.
