1st Vegan President of the American College of Cardiology

“There are two kinds of cardiologists: vegans and those who haven’t read the data.” Dr Kim Allan Williams is a remarkable man. As the first vegan president of the American College of Cardiology, what he says about the value of plant-based diets and the harms of meat-based diets is well-informed and evidence-based. Additionally, his well-earned high status within his field means that other medical professionals are more likely to sit up and listen when he speaks about plant-based nutrition.

A great fan of Dr C B Esselstyn and Dr Dean Ornish, Dr Williams regularly sends his cardiac patients to one or the other of these luminary plant-based clinicians so that they can take part in their disease reversal programmes.

I don’t mind dying, but I don’t want it to be my fault.

I have included a number of videos and a podcast where Dr Williams talks about his journey towards a plant-based diet. Whilst he doesn’t insist on a WFPB diet – suggesting that vegan cheese, vegan sausages, etc are better than any meat alternatives, even though they may not be optimal whole food nutrition – he is very clear that all animal products are harmful compared with plant products. These videos and his published research (some of which is outlined below) bear out his strong opinions on these matters.

Is a Whole Food Plant-Based Diet an Answer to Chronic Disease? 2017 Documentary

A Sample from Dr Williams’ Full List of Published Research

“The real question about WFPB diet is ‘What doesn’t it cure?’ ” (Quote from Dr Williams)

1. Introduction to the “A plant-based diet and cardiovascular disease” special issue. 2017

“All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.” (Arthur Schopenhauer, German Philosopher, 1788–1866).

Unlike many of our cardiovascular prevention and treatment strategies, including antioxidants, vitamin E, folic acid and niacin to name a few, that have disintegrated over time, the “truth” (i.e., evidence) for the benefits of plant-based nutrition continues to mount. This now includes lower rates of stroke, hypertension, diabetes mellitus, obesity, myocardial infarction and mortality, as well as many non-cardiac issues that affect our patients in cardiology, ranging from cancer to a variety of inflammatory conditions. Challenges with the science are, however, less daunting to overcome than inertia, culture, habit and widespread marketing of unhealthy foods. Our goal must be to get data out to the medical community and the public where it can actually change lives—creating healthier and longer ones.

In 2015, cardiovascular mortality went up in the US for the first time in over four decades. We apparently have reached the tipping point in cardiology. The effects of our guideline-driven management for treatment of heart disease and its risk factors, and the benefits of our ever-more-creative interventions on acute events seem to have plateaued. The rising epidemic of obesity and diabetes is now outstripping our preventive efforts, adding to the cost of healthcare and costing lives.

Starting with 2017 data, our Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) merit-based incentive payments and alternative payment models will be rewarding the absence of events more and more, and procedures less and less. So isn’t it time to move upstream, and place more emphasis on prevent-mode and less event-mode in our practices? Reading the existing literature and evaluating the impact of plant-based nutrition, it clearly represents the single most important yet underutilized opportunity to reverse the pending obesity and diabetes induced epidemic of morbidity and mortality.

2. A plant-based diet and hypertension. 2017.

There are a variety of mechanisms proposed by which plant-based nutrition leads to decrease in blood pressure. They include improved vasodilation,[10-13] greater antioxidant content and anti-inflammatory effects,[14-21] improved insulin sensitivity,[10, 22-25] decreased blood viscosity,[26, 27] altered baroreceptors,[10] modifications in both the renin-angiotensin,[13, 28-30] and sympathetic nervous systems,[10, 31] and modification of the gut microbiota.[30]

Long-term randomised controlled trials examining the impact of plant-based diets on various health outcomes, including hypertension, will further inform medical guideline creation and refine our understanding of the relationship between diet and disease. However, in lieu of such information and in the context of the data within this Special Issue, we believe that consuming a diet that is mostly or exclusively plant-based appears prudent for the prevention and treatment of hypertension.

3. A Deficiency of Nutrition Education and Practice in Cardiology. 2017


A total of 930 surveys were completed. Among cardiologists, 90% reported receiving no or minimal nutrition education during fellowship training, 59% reported no nutrition education during internal medicine training, and 31% reported receiving no nutrition education in medical school. Among cardiologists, 8% described themselves as having “expert” nutrition knowledge. Nevertheless, fully 95% of cardiologists believe that their role includes personally providing patients with at least basic nutrition information. The percentage of respondents who ate ≥5 servings of vegetables and fruits per day was: 20% (cardiologists), 21% (fellows-in-training), and 26% (cardiovascular team members).


A large proportion of cardiovascular specialists have received minimal medical education and training in nutrition, and current trainees continue to experience significant education and training gaps.

4. The 2015 Dietary Guidelines Advisory Committee Report Concerning Dietary Cholesterol. 2015


The most recent 2015 Dietary Guidelines Advisory Committee report indicated that “cholesterol is not considered a nutrient of concern for overconsumption.” However, this statement may be too general as it does not acknowledge conflicting findings in literature regarding cardiovascular risk in certain populations. Current research suggests that dietary cholesterol may increase an subject’s risk of developing diabetes, increases a diabetic patient’s risk of cardiovascular disease, and may worsen coronary risk factors in subjects who are “hyper-responders” to dietary cholesterol. In conclusion, we suggest that a more cautious approach to dietary cholesterol intake is warranted, especially in high-risk populations.
