Advice From a Vegan Cardiologist

Advice From a Vegan Cardiologist

“…Dr. Williams said he thought the research on the benefits of substituting nuts, beans and plant protein for meat was strong, but largely observational. But he was not arguing that the college of cardiology should promote veganism in its dietary guidelines. He said he would like to see large, extensive clinical trials of such diets “that pass muster” first.

Plenty of things that looked promising based on correlations that were identified in observational studies were later found to be problematic, he said, like vitamin E, hormone-replacement therapy, folic acid and, most recently, the HDL-raising drug niacin.

“There is a long list of things that, based on observational trials, we thought were beneficial, and then a randomized trial done for a long period of time showed that it wasn’t,” he said. “So I approach all of this with a sense of humility and an open mind.”

In the meantime, he said, he has made a habit of telling patients who are obese and plagued by metabolic problems like Type 2 diabetes to try exercising and eating less meat. And he discusses some of his favorite vegan foods with them.

“I recommend a plant-based diet because I know it’s going to lower their blood pressure, improve their insulin sensitivity and decrease their cholesterol,” he said. “And so I recommend it in all those conditions. Some patients are able to do it, and some are not.””
