Ultra-processed plant foods associated with increased cardiovascular disease risk
The Rise of Plant-Based Ultra-Processed Foods: A Double-Edged Sword
- In recent years, plant-based diets have surged in popularity, driven by growing awareness of health, environmental, and ethical concerns. Alongside this trend, the market for plant-based foods has expanded rapidly, leading to a new category of products: plant-based ultra-processed foods (PBUPFs). These products, often marketed as healthier and more sustainable alternatives to traditional animal-based items, have sparked significant interest and debate. However, their health implications are increasingly coming under scrutiny.
Ethical and Environmental Concerns: For those concerned about animal welfare and the environmental impact of meat production, PBUPFs provide an attractive alternative.
Health Perception: Many consumers perceive plant-based foods as inherently healthier, associating them with lower risks of chronic diseases and better overall health.
Low in Fiber and Nutrients: The processing can strip away beneficial nutrients and fiber, resulting in a product that is less nutritious than whole, minimally processed plant foods.
Presence of Additives: To achieve the desired texture and taste, these foods often contain various additives, some of which may have adverse health effects.
Prioritize Whole Foods: Base your diet on whole, minimally processed plant foods like fruits, vegetables, whole grains, legumes, nuts, and seeds.
Use PBUPFs Sparingly: Treat these products as occasional conveniences rather than staples.
Cook at Home: Whenever possible, prepare meals from scratch to have full control over the ingredients and cooking methods.
- The rise of plant-based ultra-processed foods reflects a significant shift in dietary patterns and consumer preferences. While they offer benefits in terms of convenience and ethical considerations, their health impacts warrant careful consideration. By balancing the use of PBUPFs with a diet rich in whole plant foods, individuals can enjoy the benefits of a plant-based diet without compromising their health. As research continues to evolve, staying informed and making mindful choices will be key to navigating the complexities of modern plant-based eating.
What Are Plant-Based Ultra-Processed Foods?
- Ultra-processed foods (UPFs) are formulations of ingredients, mostly of industrial use, derived from foods, including additives like preservatives, sweeteners, and colorings. When these processes are applied to plant-based ingredients, the result is plant-based ultra-processed foods. Examples include plant-based burgers, sausages, cheeses, and ready-to-eat meals. These products are designed to mimic the taste, texture, and appearance of their animal-based counterparts, often using a combination of refined ingredients and food additives.The Appeal of PBUPFs
The appeal of PBUPFs is multifaceted: Convenience: They offer a quick and easy alternative to cooking from scratch, fitting well into busy lifestyles.Ethical and Environmental Concerns: For those concerned about animal welfare and the environmental impact of meat production, PBUPFs provide an attractive alternative.
Health Perception: Many consumers perceive plant-based foods as inherently healthier, associating them with lower risks of chronic diseases and better overall health.
Health Concerns and Nutritional Profile
- Despite their plant-based origins, PBUPFs often share nutritional characteristics with their traditional ultra-processed counterparts: High in Sodium and Added Sugars: Many PBUPFs contain high levels of sodium and added sugars to enhance flavor and shelf life.Low in Fiber and Nutrients: The processing can strip away beneficial nutrients and fiber, resulting in a product that is less nutritious than whole, minimally processed plant foods.
Presence of Additives: To achieve the desired texture and taste, these foods often contain various additives, some of which may have adverse health effects.
Link to Cardiovascular Disease
- Emerging research suggests that PBUPFs may not be as heart-healthy as whole plant foods. A study published in the Journal of the American College of Cardiology found a correlation between the consumption of ultra-processed foods and an increased risk of cardiovascular disease. The mechanisms are thought to be similar to those observed with traditional UPFs: high levels of sodium, unhealthy fats, and sugars, along with a low nutrient density, can contribute to risk factors like hypertension, inflammation, and poor lipid profiles.Balancing Convenience and Health
- While PBUPFs can play a role in transitioning to a plant-based diet, it is essential to approach them with caution. Here are some tips to ensure a balanced diet: Read Labels Carefully: Look for products with lower sodium and sugar content and fewer additives.Prioritize Whole Foods: Base your diet on whole, minimally processed plant foods like fruits, vegetables, whole grains, legumes, nuts, and seeds.
Use PBUPFs Sparingly: Treat these products as occasional conveniences rather than staples.
Cook at Home: Whenever possible, prepare meals from scratch to have full control over the ingredients and cooking methods.

Health Risks Associated with Plant-Based Ultra-Processed Foods
- A new analysis has revealed that plant-based ultra-processed foods (UPFs) may pose a higher risk for cardiovascular diseases compared to less-processed plant-based foods. This research, spearheaded by the University of São Paulo with contributions from Imperial College London, analyzed data from over 118,000 individuals. The findings suggest that while plant-based diets are generally linked to a reduced risk of diseases, consuming UPFs can lead to worse health outcomes.Key Findings from the Study
- The study found that consuming plant-based UPFs was associated with a 7% increase in the risk of cardiovascular diseases compared to consuming unprocessed plant-based foods. Additionally, the research indicated that both plant-based and animal-based UPFs were linked to a higher risk of cardiovascular diseases and mortality from these conditions.
- Published in The Lancet Regional Health—Europe, the study underscores that despite being marketed as healthy alternatives, plant-based UPFs may contribute to poorer health outcomes. The researchers recommend updating dietary guidelines to encourage reducing UPF consumption while promoting whole, minimally processed plant-based foods.
- The researchers classified food items according to the Nova classification system into UPFs and non-UPFs (unprocessed or minimally processed foods, processed culinary ingredients, and processed foods). These groups were further divided into plant-based and animal-based categories. The study found no association between the consumption of all plant-based foods and cardiovascular diseases. However, higher consumption of plant-based non-UPFs was linked to better health outcomes, and replacing plant-based UPFs with non-UPFs reduced the risk of cardiovascular diseases by 7% and related mortality by 15%.
- Based on the evidence, the researchers advocate for nutritional guidelines that promote plant-based diets while emphasizing the importance of reducing UPF consumption. Dr. Renata Levy, a professor at the University of São Paulo, stressed the importance of research like this in guiding public policies and encouraging the reduction of ultra-processed food consumption, regardless of whether they are of animal or plant origin.
Conclusion- Published in The Lancet Regional Health—Europe, the study underscores that despite being marketed as healthy alternatives, plant-based UPFs may contribute to poorer health outcomes. The researchers recommend updating dietary guidelines to encourage reducing UPF consumption while promoting whole, minimally processed plant-based foods.
Insights from Researchers
- Dr. Eszter Vamos, co-author from the School of Public Health at Imperial College London, emphasized that fresh plant-based foods, such as fruits, vegetables, whole grains, and legumes, are known for their significant health and environmental benefits. She pointed out that ultra-processed foods, although often marketed as healthy, do not offer the same protective health effects and are linked to adverse health outcomes.Plant-Based Diets and Cardiovascular Health
- Plant-based diets are generally associated with a reduced risk of cardiovascular diseases, including heart attacks and strokes. However, many meat-free alternatives like sausages, burgers, and nuggets are classified as ultra-processed foods. These foods typically contain high levels of salt, fat, sugar, and artificial additives, all of which have been linked to negative health outcomes such as obesity, type 2 diabetes, cardiovascular disease, and cancer.Study Details
- Researchers from the University of São Paulo, Imperial College London, and the International Agency for Research on Cancer (IARC) conducted this study using data from the UK Biobank. They examined the dietary habits of more than 118,000 people aged 40 to 69 from England, Scotland, and Wales. The participants' diets were assessed over at least two days, and these data were then linked to hospital and mortality records to investigate cardiovascular diseases.- The researchers classified food items according to the Nova classification system into UPFs and non-UPFs (unprocessed or minimally processed foods, processed culinary ingredients, and processed foods). These groups were further divided into plant-based and animal-based categories. The study found no association between the consumption of all plant-based foods and cardiovascular diseases. However, higher consumption of plant-based non-UPFs was linked to better health outcomes, and replacing plant-based UPFs with non-UPFs reduced the risk of cardiovascular diseases by 7% and related mortality by 15%.
Recommendations
- Dr. Fernanda Rauber, the study's first author, noted that despite being plant-based, UPFs could increase risk factors like dyslipidemia and hypertension due to their composition and processing methods. She highlighted that food additives and industrial contaminants in these foods could cause oxidative stress and inflammation, exacerbating health risks. Consequently, the study supports shifting towards plant-based food choices that consider the degree of processing to improve cardiovascular health outcomes.- Based on the evidence, the researchers advocate for nutritional guidelines that promote plant-based diets while emphasizing the importance of reducing UPF consumption. Dr. Renata Levy, a professor at the University of São Paulo, stressed the importance of research like this in guiding public policies and encouraging the reduction of ultra-processed food consumption, regardless of whether they are of animal or plant origin.
- The findings from this comprehensive study underscore the nuanced relationship between plant-based diets and cardiovascular health. While plant-based diets are broadly associated with reduced risks of cardiovascular diseases, the type and degree of processing of these foods play a critical role in their health outcomes. The study highlights that plant-based ultra-processed foods (UPFs) are linked to a higher risk of cardiovascular diseases compared to their less-processed counterparts. This indicates that not all plant-based foods offer the same health benefits.
- Researchers from the University of São Paulo, Imperial College London, and the International Agency for Research on Cancer advocate for a shift in dietary guidelines. They recommend a focus on consuming whole, minimally processed plant-based foods while reducing the intake of UPFs, whether plant-based or animal-based. This approach aims to maximize the health benefits of plant-based diets and mitigate the risks associated with ultra-processed foods.
- The study’s insights emphasize the importance of being mindful of food processing levels when making dietary choices. Fresh, whole foods such as fruits, vegetables, whole grains, and legumes should be prioritized to achieve better health outcomes. As public awareness grows, it is crucial for nutritional guidelines and policies to reflect these findings, encouraging a reduction in ultra-processed food consumption for improved cardiovascular health and overall well-being.
