This is a shocking discovery.
Recent findings published in the Canadian Journal of Cardiology suggest that plant-based meat alternatives, despite their highly processed nature, may offer significant cardiovascular health benefits compared to traditional meat products. The review highlighted improvements in key indicators of heart disease risk when individuals switched from meat to plant-based options, including reductions in total cholesterol, LDL cholesterol (commonly known as “bad” cholesterol”), and body weight.
One notable clinical trial discussed in the review showed that participants who incorporated plant-based meats into their diets experienced notable health improvements. These included a 13% decrease in total cholesterol, a 9% reduction in LDL cholesterol, a 53% drop in triglycerides, and an 11% increase in HDL cholesterol, which is beneficial for heart health. Dr. Ehud Ur, the senior author of the study from the University of British Columbia, emphasized that opting for plant-based meat substitutes was associated with lower cardiovascular risk factors.
However, the review also pointed out significant variations in the nutritional profiles of different plant-based meat substitutes, particularly concerning levels of sodium and saturated fats. For example, comparisons between different brands of plant-based burgers revealed substantial differences: one older brand contained 6% of the recommended daily intake of saturated fat and no cholesterol, whereas a newer brand had 30% saturated fat and 27% cholesterol.
Despite concerns about the processing involved in making plant-based meats, Dr. Ur clarified that not all processing methods are harmful to health. He noted that these products generally lack harmful saturated fats and certain carbohydrates that are associated with negative health outcomes. Nonetheless, he called for further research, including randomized trials comparing the cardiovascular outcomes of individuals consuming plant-based meats versus traditional meats, acknowledging the challenges in conducting such studies.
Dr. Walter Willett from the Harvard T.H. Chan School of Public Health supported the idea that while whole foods are generally preferable, there may be benefits to incorporating certain ultra-processed foods like plant-based meat alternatives. He referenced a 2020 study demonstrating significant reductions in cholesterol and blood pressure among participants who switched from meat to plant-based alternatives.
Dr. Anu Lala, director of heart failure research at Mount Sinai Fuster Heart Hospital, echoed the need for long-term studies to fully grasp the health impacts of plant-based meats. She stressed the importance of comprehensive research efforts similar to those dedicated to understanding the benefits of the Mediterranean diet. Such studies, she argued, could provide valuable insights into how plant-based diets, including meat substitutes, influence long-term cardiovascular health.
