Lower risk of cancer, diabetes and heart disease

Switching to a plant-based diet promotes healthier aging and reduces the risk of common diseases such as diabetes, cancer and heart disease by up to 50 percent. This consensus comes from an American medical committee that summarized the results of various nutritional studies in recent years.

Researchers from the American Physicians Committee for Responsible Medicine have analyzed the results of numerous nutritional tests in recent years. The team came to the conclusion that a plant-based diet promotes healthy aging and protects against common diseases. The committee's editorial was recently published in the Journal of the American College of Nutrition.

Fruits, vegetables and legumes against chronic diseases

A person's age is a risk factor for many non-communicable chronic diseases, such as cancer and type 2 diabetes. The current article shows that a plant-based diet is an effective way to protect yourself from such common diseases. If you change your diet accordingly, you can cut your risk in half of developing an age-related illness.

The study authors conclude that a healthy plant-based diet that is rich in fruits, vegetables, whole grains and legumes appears to be an effective tool to delay the aging process, reduce the risk of age-related diseases and life expectancy to increase.

This reduces the risks associated with a plant-based diet

The analysis shows that the risks for numerous diseases are reduced by switching to a plant-based diet. According to the study, the risk for

  • a metabolic syndrome by 50 percent,
  • Type 2 diabetes by around 50 percent
  • coronary heart disease by about 40 percent,
  • Circulatory disorders in the head by almost 30 percent,
  • Alzheimer's disease by over 50 percent.

Longer life through plant-based nutrition

The researchers also point out that a plant-based diet is associated with increased life expectancy. This shows an evaluation of areas in which the population lives mainly from plant food. The team attributes the effect to the high proportion of phytochemicals and antioxidants in the diet.

In 2050 there are significantly more old people

"The global population of adults who are 60 years of age or older is expected to double from 841 million to 2 billion by 2050," says study author Hana Kahleova. This represents a clear challenge for the health system. Simple dietary changes could help the population to live a longer and healthier life.

Healthcare costs could explode

According to the Centers for Disease Control and Prevention (CDC), lifestyle-related chronic illnesses are the leading cause of death and disability in the United States. At the same time, these diseases are the highest cost factor in annual health expenditure. (vb)
