Research shows that plant-based protein diets may help reduce the risk of death

A diet high in protein, especially vegetable protein, has been associated with a lower risk of death from all causes, a new study found.

A team of researchers from Tehran Medical University in Iran, Harvard TH Chan Public Health School, Brigham and Women’s Hospital and Harvard Medical University have found that they have a protein-rich diet that includes plants such as beans and nuts, but whole grains have heart disease. , Is associated with a reduced risk of developing chronic and potentially fatal illnesses such as diabetes and stroke. On the other hand, regular intake of red meat and high intakes of animal protein are associated with many health problems.

Published in British Medical Journal (BMJ), Researchers aim to investigate and quantify potential dose-response relationships between total animal and plant protein intakes and risk of death from any cause, including cancer and cardiovascular disease. It was made.

The team worked on a high-protein diet and conducted a systematic review and meta-analysis of previous studies dealing with how it affects overall health.

the study

To reach the findings, the researchers reviewed the results of 32 studies that provided estimates of the risk of all-cause, cardiovascular, and cancer death in adults age 19 and older. The study was conducted carefully and extensively to remove bias, a common problem that could impact results.

The team used a mathematical model to compare the effects of the highest and lowest protein intake categories. They analyzed a dose-response relationship between protein consumption and risk of death.

A total of 715,128 participants were included in the study. During a follow-up period of about 32 years, 113,039 died, of which 16,429 were associated with cardiovascular disease and 22,303 were associated with cancer.

What are the research results?

The team found that protein intake was associated with a lower risk of death when compared to the highest and lowest levels of protein intake. They also found that although there was no significant correlation between animal protein intake and cardiovascular mortality, there was an association between plant protein and CV mortality.

They also found that high total protein intake was associated with a reduced risk of death from all causes. By comparison, vegetable protein intake was also associated with a reduced risk of death from all causes and from cardiovascular disease.

Research results have important implications because people can increase their intake of plant-based proteins by replacing animal proteins. This can have a significant impact on adult longevity and health.

“Therefore, our findings strongly support existing dietary recommendations to increase plant protein consumption in the general population. Because most of the studies included in the meta-analysis are from Western European countries, and few studies have been reported from other countries, extrapolation of these findings to people around the world should be done carefully. “ The researchers concluded the study.

“Therefore, more research is needed. Additional research should also focus on the mechanisms by which dietary proteins affect mortality.” They added.

In another study, a team of researchers found that eating a plant-rich diet could significantly delay the aging process, illness, and death. Published in JAMA Internal Medicine, Research highlights the benefits of shifting to a plant-based diet to promote overall health.

The team found that higher vegetable protein intakes were associated with a slight reduction in overall and cardiovascular mortality risk. The findings provide evidence that dietary changes or modifications in the choice of protein source can affect health and longevity.

In conclusion, this large cohort study showed a small but significant association between increased plant protein intake and reduced overall and CVD mortality, especially for plant proteins derived from bread. Significant inverse correlations were observed in the replacement of protein with vegetable protein for lean meat protein, cereal, pasta”

“The findings from this and previous studies provide evidence that dietary changes in choice of protein source may promote health and longevity.” They added.
