Dr. Ronald Krauss, M.D. is the director of atherosclerosis research at Children’s Hospital Oakland Research Institute, Adjunct Professor at UCSF and UC Berkeley. Dr. Krauss is really one of the pioneering scientists that changed the way we all think about cholesterol and saturated fat. He developed an assay that allows the quantification of low density lipoprotein particle size and concentration (known to the wider world as LDL cholesterol) based on a technique which determines the size of the particle based on physics...meaning the speed at which it flies through the air. In this episode, Rhonda and Ron discuss what HDL and LDL cholesterol are, what they do in the body and how they play a role in heart disease. We talk about what small, dense LDL particles are, how they form, what effect eating saturated fat versus refined carbohydrates have on LDL particle size and heart disease risk and more generally what the main risk factors for heart disease are. Ron also talks about the good, bad and the ugly of LDL-lowering drugs known as statins and much more.

Meet some of the CHORI bar team: Dr. Bruce Ames, Dr. Joyce McCann, and Dr. Mark Shigenaga. On this podcast we talk about the different types of HDL and LDL cholesterol and what they do in the body. We discuss a low-calorie, micronutrient- and fiber-dense nutrition bar (referred to as the CHORI bar) that Bruce and I briefly touched on in a previous conversation, how each of the components of the bar from the vitamins and minerals to the fiber and polyphenols are all really important but have separate functions in the body that can work together in much the same way an orchestra play their individual parts to create a symphony that is larger than their individual roles, how the chori bar raised a certain type of HDL in lead adults in just two weeks, how eating the CHORI bar raised HDL, lowered triglycerides and small LDL particles, and improved insulin sensitivity after eight weeks in overweight/obese individuals all without them changing their diet.

The CHORI bar is not available for consumers yet but you can keep up with choribar updates on bruceames.org/choribar.

Dr. Aubrey de Grey is a biomedical gerontologist and the founder of the SENS research foundation which aims to find technologies that can repair the various types of damage that occur during the aging process. In this episode Rhonda and Aubrey discuss the types of damage that cause aging, how aging results in a decrease in the capacity to repair damage, what role epigenetics play in aging, how people age at different rates, chronic inflammation as a driver of aging, factors that are in young blood that repair damage, the role of nutrition in aging, and recent technologies such as CRISPR, induced pluripotent stem cells that will advance anti-aging research and more. You can find Aubrey on twitter at @aubreydegrey, and his foundation at www.sens.org.
