Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients.
Podcast Summary
Introduction
Dr. Warrick Bishop is a practicing cardiologist and author dedicated to educating patients about heart health. In this episode, he tackles the complex but important topic of hydrocarbons, fats, oils, and lipids, using creative metaphors to make the chemistry accessible. Dr. Bishop believes that understanding the language and science behind these compounds will help patients better understand nutrition, storage, and medical treatments related to cardiovascular health.
Key Takeaways
-
Hydrocarbons are molecules made up only of hydrogen and carbon atoms, forming the basis of fuels like petrol, and can be arranged in chains or rings.
-
A useful way to understand hydrocarbons is to imagine carbon atoms as children with four arms that must always hold something (represented as hydrogen atoms or "hula hoops").
-
Saturated hydrocarbons/fatty acids have single bonds between carbon atoms and hold the maximum number of hydrogen atoms possible, typically solid at room temperature.
-
Unsaturated fatty acids contain double bonds between some carbon atoms (where they "hold hands" with multiple arms), making them no longer hold the maximum hydrogen possible.
-
Monounsaturated fatty acids have one double bond in the chain, while polyunsaturated fatty acids have multiple double bonds.
-
Trans fats are created through chemical manipulation where the bonds between carbons are distorted (arms crossed), and these are associated with raising bad cholesterol and worse health outcomes.
-
Cis bonds are the normal, natural bonds between carbon atoms (running parallel), whereas trans bonds result from artificial processing.
-
Fatty acids are created by adding oxygen to hydrocarbon chains, specifically adding a hydroxyl group (oxygen and hydrogen together) to the end of the chain.
-
Saturated fatty acids with 16 carbon atoms are solid at room temperature and are the main component of animal fats commonly seen in meat and bacon.
