Clinical Trials & Other Research Studies
Plant-Based Cardiovascular Clinical Trial
The Purjes Foundation funded a clinical trial at NYU Medical Center comparing a plant-based diet with the diet recommended by the American Heart Association (the “AHA”) for people with cardiovascular disease. The AHA diet contains animal-based foods. The trial involved 100 participants with severe cardiovascular disease randomly divided into two groups, one eating plant-based foods and the other eating the diet recommended by the AHA, for a period of 8 weeks. All the food was paid for by the Purjes Foundation, as were many other costs and fees.
The primary blood marker tested was C-Reactive Protein, referred to as “hsCRP” or just “CRP”. This is an important marker of inflammation that is involved in virtually every inflammatory chronic disease. The lower the CRP, the better. The Purjes Foundation trial demonstrated conclusively that the patients on the plant-based diet saw their CRP levels fall 32%, or more than four times the 7% drop registered by the AHA group.
These results were so significant that the Wall Street Journal published a feature article on the trial. Visit the Articles page to read the article.
In December 2018, the peer-reviewed Journal of the American Heart Association, a highly regarded medical journal, published the research article submitted by the NYU principal investigators describing the details and results of the trial. That research article can be found here.
Erectile Dysfunction Trial
The Purjes Foundation has agreed in principle to fund one or more erectile dysfunction clinical trials at Montefiore Hospital, a unit of the Albert Einstein School of Medicine in the Bronx, NY.
The studies will be randomized controlled clinical trials in which men will be randomly assigned to either a plant-based diet group, or a control group that will be on a high protein, low carbohydrate “he-man” diet. There may also be a second control group on the standard American diet.
Men who have erectile dysfunction typically suffer from poor blood circulation. In fact, erectile dysfunction is often the “canary in the coal mine”, the early warning signal of cardiovascular disease. The trial at NYU Medical Center funded by the Purjes Foundation that demonstrated improved cardiovascular markers on a plant-based diet, suggests there should be improved outcomes for erectile dysfunction on a similar diet. Most people think that a “he-man” diet loaded with animal protein is synonymous with male virility, but if it can be shown that a plant-based diet improves erectile function while the “he-man” diet actually worsens it, that would be big news.
The studies at Montefiore Hospital will be conducted in 2018 and 2019.
The Purjes Foundation is in active discussions with several other hospitals and clinics for proposed trials in various chronic diseases. These include more cardiovascular trials, as well as diabetes, lupus, and rheumatoid arthritis.
