A new study from Harvard T.H. Chan School of Public Health suggests that a diet rich in plant-based protein may significantly lower the risk of cardiovascular disease (CVD) and coronary heart disease (CHD). The research highlights the potential heart health benefits of replacing red and processed meats with plant protein sources such as nuts and legumes.
The study analyzed 30 years of dietary, lifestyle, and health data from nearly 203,000 men and women participating in the Nurses’ Health Studies I and II and the Health Professionals’ Follow-up Study. Participants reported their diets every four years, allowing researchers to track long-term trends and their effects on heart health.
After adjusting for various health and lifestyle factors, the study found that individuals with the highest plant-to-animal protein ratio (~1:1.3) had a 19% lower risk of CVD and a 27% lower risk of CHD. Those with the highest protein intake (21% of total energy from protein) and a balanced plant-to-animal protein ratio experienced even greater benefits, with a 28% reduced risk of CVD and a 36% lower risk of CHD compared to those with the lowest protein intake (16% of energy from protein).
Researchers emphasized that swapping red and processed meats for plant-based proteins contributed to improved heart health and better metabolic risk profiles. However, they also noted that further studies are needed to determine if there is an upper limit to the benefits of plant protein consumption.
This study adds to a growing body of evidence supporting plant-based diets as a strategy for reducing heart disease risk. Health experts recommend incorporating more plant proteins, such as beans, tofu, and whole grains, into daily meals to promote overall cardiovascular well-being.
