Summary

Researchers are testing whether a plant-based diet can improve heart health in police officers who are overweight or have type 2 diabetes. The trial enrolls 20 officers from the Washington, D.C. police department and randomly assigns them to either follow a vegan diet with weekly instructions or eat their usual unrestricted diet. The team measures changes in body weight, blood pressure, cholesterol levels, and quality of life to see if the diet makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a plant-based (vegan) diet
What this could lead to
If it works, this could point toward a simple, low-cost way for police officers and other high-stress workers to lower their risk of heart disease and type 2 diabetes.
What could go wrong
This is a very small study of 20 people, so any changes may be due to chance or hard to repeat in a larger group. Sticking to a vegan diet can be difficult, and participants may not follow it closely enough to see real effects.
