Plant-based diets support healthy aging and could significantly reduce the risk of cardiometabolic diseases, including diabetes and heart disease, finds a new review.

Plant-based diets are becoming increasingly popular in the United States. A 2017 report estimated that 6% of U.S. consumers eat a vegan diet, up from just 1% in 2014.

There are many reasons why people choose to adopt a vegan diet, including avoiding harm to animals and mitigating the environmental impact of intensive farming.

A plant-based diet also provides health benefits. This diet is higher in fiber and lower in cholesterol and fat than an omnivorous diet, and it scores higher on the Healthy Eating Index.

A new review of the evidence on plant-based diets suggests that they may also protect against type 2 diabetes and heart disease and could reduce cardiometabolic-related deaths in the U.S.

The Physicians Committee for Responsible Medicine (PCRM) in Washington, DC, led the review, which features in the Journal of the American College of Nutrition.

A cost effective approach

Although aging is inevitable, the authors say that adopting a healthful, plant-based diet could help delay the aging process and reduce the risk of age-associated diseases. It could also increase a person’s life expectancy.

“[S]imple diet changes can go a long way in helping populations lead longer, healthier lives.”

This conclusion is in line with the findings of the Global Burden of Disease Study 2017, which showed that a low intake of fruits, vegetables, and whole grains and a high intake of red and processed meats are major risk factors for disease.

The authors say that as well as offering significant benefits for health, plant-based diets could reduce healthcare costs in the U.S., which are close to $3.5 trillion each year. They suggest that a healthful diet is a cost effective approach to preventing disease and recommend incorporating it into everyday life.
