Ultra Processed Plant-Based Foods Increase Mortality Risk

The Dark Side of Ultra-Processed Plant-Based Foods

Ultra-processed plant-based foods are becoming increasingly common in the Western diet. About 58% of the typical Western diet includes ultra-processed foods, made entirely through industrial processes. These foods, such as packaged breads, ice cream and sports drinks, are often convenient and tasty. However, they come with significant health risks.

Recent studies have shown that a high intake of ultra-processed foods is linked to various health problems. These include cognitive decline, depression, cancer, and now, as recent research suggests, cardiovascular disease and increased mortality risk. A new study published in The Lancet Regional Health — Europe indicates that even plant-based ultra-processed foods may not be as healthy as they seem.

In fact, recent research  found that greater intake of ultra-processed foods was associated with an increased risk for 32 adverse health outcomes, including heart issues, sleeping problems, type 2 diabetes, overweight and obesity, and mental health conditions.

While plant-based diets are often recommended for their health benefits, the level of processing in these foods can negate these benefits. This highlights the importance of choosing minimally processed foods for better health outcomes. The study underscores the need for more awareness about the potential risks associated with ultra-processed plant-based foods, encouraging a shift towards natural and clean label options.

What are Ultra-Processed Plant-Based Foods?

Ultra-processed plant-based foods are items that undergo extensive industrial processing. They often contain ingredients like additives, preservatives, flavor enhancers, and artificial colors.

Common examples include packaged breads, vegan burgers, plant-based sausages, and certain dairy-free cheeses. These foods are designed to mimic the taste and texture of whole foods but lack their nutritional value.

The popularity of these foods stems from their convenience and the growing interest in plant-based diets. Many people assume that because these products are plant-based, they are automatically healthier. This assumption can be misleading.

In the Western diet, ultra-processed foods make up a significant portion, with about 58% of daily intake. The industrial processes strip away essential nutrients and add unhealthy components. This contributes to various health issues, including obesity, type 2 diabetes, and cardiovascular diseases.

Understanding what constitutes ultra-processed plant-based foods helps consumers make better dietary choices. By recognizing these products, individuals can opt for whole, minimally processed foods that offer better health benefits.

Significant Health Risks

Ultra-processed foods pose significant health risks, regardless of whether they are plant or animal-based. Numerous studies have linked high consumption of these foods to various health issues. Conditions such as cognitive decline, depression, and cancer have all been associated with diets high in ultra-processed foods.

A recent study published in The Lancet Regional Health — Europe adds to this growing body of evidence. It highlights the dangers of consuming ultra-processed plant-based foods. The study found that for every 10% increase in calorie intake from these foods, participants had a 5% higher risk of cardiovascular disease. Additionally, the risk of death from cardiovascular diseases increased by 12%.

The research underscores how industrial processing can diminish the nutritional quality of plant-based foods. Ingredients like added sugars, unhealthy fats, and high levels of sodium contribute to these adverse health outcomes.

The study also points out that minimally processed plant-based foods are associated with lower health risks. For every 10 percentage point increase in calories from non-ultra-processed plant-based foods, there was a 7% lower risk of cardiovascular disease and a 13% lower risk of mortality from cardiovascular disease.

These findings suggest that the degree of processing plays a crucial role in determining the health impacts of plant-based foods. While plant-based diets can offer significant health benefits, choosing whole, minimally processed foods is essential to maximizing these benefits and reducing health risks.

Focus on Plant-Based Ultra-Processed Foods

Researchers are increasingly focusing on plant-based ultra-processed foods due to the lack of comprehensive studies on their health impacts. This recent study aimed to fill that gap, particularly concerning cardiovascular disease.

Dr. Fernanda Rauber, the lead study author from the Centre for Epidemiological Research in Nutrition and Health at the University of São Paulo, highlights the growing popularity of plant-based diets. She notes that the food industry often uses health claims like “vegetarian,” “vegan,” and “plant-based” to market these products. While these claims can be enticing, they can also be misleading. People might believe these products are inherently healthy, which isn’t always the case.

Dr. Rauber explains the difference between animal-based and plant-based ultra-processed foods. Plant-based versions contain mainly plant-derived ingredients, excluding meat, dairy, eggs, or cheese. Despite this, they often still undergo significant processing, adding sugars, unhealthy fats, and preservatives.

As the public increasingly adopts plant-based diets, it’s crucial to consider food processing levels. The study found that even plant-based ultra-processed foods could lead to higher cardiovascular disease risks. This contradicts the common perception that all plant-based foods are beneficial.

With these findings, dietary guidelines need to evolve. Incorporating considerations about food processing can help refine recommendations. This ensures people understand that minimally processed foods provide the most health benefits. As Dr. Rauber emphasizes, it’s not just about consuming plant-based foods, but also about choosing those that are least processed.

Study Findings and Analysis

The recent study published in The Lancet Regional Health — Europe provides crucial insights into the health impacts of ultra-processed plant-based foods. Dr. Fernanda Rauber and her team analyzed data from almost 127,000 participants in the UK Biobank who provided dietary information between 2009 and 2012. The participants were followed up for a median of nine years, allowing for a comprehensive analysis of long-term health outcomes.

The study revealed significant findings. For every 10% increase in calorie intake from plant-based ultra-processed foods, participants experienced a 5% higher risk of cardiovascular disease and a 12% higher risk of death from cardiovascular diseases.

Dr. Rauber commented on these results, stating, “We hypothesized that the industrial processing of foods would influence the relationship between plant-based food intake and cardiovascular disease, but we didn’t know to what extent. We were surprised by how consistently the results showed that consuming plant-sourced non-ultra-processed foods was associated with a lower risk of developing cardiovascular disease while consuming plant-sourced ultra-processed foods was associated with a higher risk.”

For every 10% increase in calorie intake from these foods, participants had a 5% higher risk of cardiovascular disease, and the risk of death from cardiovascular diseases increased by 12%.

More Processing Equals Higher Risk

Interestingly, the study found no association between the consumption of all plant-based foods and cardiovascular disease risk. However, the level of processing made a significant difference. Every 10 percentage point increase in calories from plant-sourced non-ultra-processed foods was linked to a 7% lower risk of cardiovascular disease and a 13% lower risk of mortality from cardiovascular disease.

Dr. Rauber emphasized, “The higher the consumption of plant-sourced non-ultra-processed foods, the lower the risk of these diseases. This underscores the importance of not just consuming plant-based foods, but specifically choosing those that are minimally processed to maximize health benefits.”

These findings have significant implications for dietary guidelines and public health recommendations. Dr. Rauber suggests that doctors can use this information to better advise their patients. “Doctors can use this information to emphasize to their cardiovascular disease patients that while plant-based diets can be beneficial, it is crucial to limit the consumption of all ultra-processed foods, including those that are plant-based. They should explain how minimally processed plant-based foods are associated with a lower risk of cardiovascular disease and mortality, guiding patients to make healthier dietary choices,” she said.

Confusing Marketing Messages

Supporting these findings, Jennifer Wong, MD, a board-certified cardiologist, noted that the results align with diets recommended by the American Heart Association, such as the DASH diet. She remarked, “Studies like these remind us that when encouraging patients to avoid animal products high in saturated fat and seek more plant-based options, [we should] also bring up the importance of seeking whole foods and avoid processed packaged foods even if plant-based.”

Wong’s perspective highlights a critical point: the type of plant-based foods consumed matters significantly. She also expressed curiosity about whether different types of processed foods, such as those with lower fat, salt, or sugar content, might have different outcomes. This indicates a need for further research to explore these nuances.

Additionally, Monique Richard, a registered dietitian nutritionist, was not surprised by the observations. She explained that marketing messages can often be confusing for the general public.

Richard noted, “If they understand something to be made of plants and understand that they are encouraged to eat more, they may perceive it is healthier than the animal counterpart. ‘Plant-based’ does not automatically equate to nutritious. Often, meat analogs and ultra-processed foods have added sugar, salt, fat, cholesterol, [and] preservatives, or [they] are so processed that they no longer include the original beneficial components such as fiber or the phytochemicals and water-soluble vitamins such as vitamin C, folate, or riboflavin.”

Consumer Education is Key

Both experts agree that minimally processed plant-based foods are preferable. They stress the importance of educating consumers about the differences between various plant-based products. This education can help individuals make informed choices that promote better health outcomes. By focusing on whole, minimally processed foods, people can reap the full benefits of plant-based diets.

Incorporating these expert opinions into public health messages and dietary guidelines can help clarify the potential risks and benefits of plant-based diets. This can guide consumers toward healthier choices and reduce the risk of cardiovascular diseases and other health issues associated with ultra-processed foods.
