Plant-based ultra-processed foods have been linked to poor health outcomes, according to new research that challenges the perception of these products as healthy alternatives. A collaborative study by researchers from the University of São Paulo, Imperial College London, and the International Agency for Research on Cancer delved into the effects of ultra-processed plant-based foods compared to traditional plant-based diets.
Despite being marketed as healthier options, meat-free alternatives like sausages, burgers, and nuggets fall under the category of ultra-processed foods (UPFs). The research team suggests that dietary guidelines should now emphasize reducing the consumption of UPFs while promoting plant-based diets.
Findings from a study involving 118,000 individuals revealed that although plant-based diets are generally associated with a reduced risk of diseases, the overall impact of UPFs on health was negative. Consuming plant-based UPFs was specifically linked to a 7% higher risk of cardiovascular diseases compared to unprocessed plant-based foods.
Notably, the study found that both animal and plant-based UPFs increased the risk of cardiovascular diseases and related mortality. Dr. Eszter Vamos, a co-author of the study from Imperial College London, highlighted the importance of fresh plant-based foods like fruits, vegetables, whole grains, and legumes for health benefits.
Dr. Renata Levy from the University of São Paulo emphasized the significance of research in understanding the impacts of ultra-processed plant-based foods on cardiovascular health. The study sheds light on the potential risks associated with additives and industrial processing in meat-free items, which can lead to oxidative stress and inflammation.
As the debate on the health implications of ultra-processed foods continues, it becomes evident that a shift towards whole, unprocessed plant-based foods may offer more protective health effects. Public policies and dietary recommendations may need to reconsider the promotion of certain meat-free alternatives in light of these findings.
