The vegetarian diet can promote healthy aging and reduce the global burden of disease, according to a new editorial. Researchers from the Physicians Committee for Responsible Medicine reviewed clinical and epidemiological studies on the topic. They found that aging processes increase the risk of non-communicable chronic diseasesplant-based dietHowever, it can be helpful. The results show that such a diet can reduce the risk of type 2 diabetes, cancer, heart disease and overall death by almost 50%.
Good reasons for a vegetarian diet
The authors claim that modulating lifestyle and risk factors with a healthy diet are powerful tools that could delay the aging process. This also allows people to reduce age-related comorbidities and mortality and increase life expectancy. They cite studies showing that plant-based diets are rich in fruits, vegetables, grains and legumes. According to the study results, the risk of developing metabolic syndrome and type 2 diabetes can be reduced by around 50%. This includes coronary heart disease and cerebral vascular disease. The risk of developing Alzheimer's is also reduced by more than 50% through a vegetarian diet. The researchers also note that plant-based diets are associated with increased life expectancy. This is evidenced by the so-called “blue zones” of the world, where the population lives mainly on plant-based foods. These are rich in phytochemicals and antioxidants and ensure a longer life expectancy.
The global population of adults aged 60 and over is expected to double from 841 million to 2 billion by 2050. This presents clear challenges for most healthcare systems. Fortunately, simple dietary changes can help populations live longer, healthier lives. TheAuthors also notethat these improvements in health will reduce health care costs caused by chronic diseases. According to the Centers for Disease Control and Prevention, chronic lifestyle-related diseases are the leading cause of disability and death. In addition, these account for the majority of annual healthcare expenditure.
