Rich Roll interviews Dr Kim Williams, a renowned cardiologist and fellow of the American College of Cardiologists.
Dr Williams is passionate about the impact of diet on society. What I like about this interview is the way Dr Williams clearly explains some of the problems inherent in dietary research including industry funding and positive publication bias. He also summarises the latest research into the impacts of saturated fat and sugar consumption. In a nutshell, these are some of the points he touches on:
Saturated fat consumption: Dr Williams advocates that there is no safe level of saturated fat consumption and as a result, he does not recommend consuming any animal products. He famously said: “There are two kinds of cardiologists, vegans and those who haven’t read the data.”
Sugar (and refined grains) consumption: Dr Williams points out that we are accumulating so much more data on sugar. He discusses the biological mechanisms for sugar contributing to heart disease via insulin resistance, the addictive nature of sugar and the political issues surrounding it by which he refers to the farm subsidies that support the production of high fructose corn syrup (HFCS), making HFCS cheap and ubiquitous in processed food.
The logical and well reasoned opinions of Dr Williams as he advocates for lifestyle interventions are a pleasure to hear. In addition to the thoughtful content, his dulcet tones makes me want to listen to him talk forever.
