Fructose

Twenty percent of obese people are in metabolically great health. Meanwhile sixty percent of supposedly ‘healthy’ weight people are metabolically unwell and at risk of a host of chronic diseases. With this in mind, do we need to change our thinking about what ‘being fat’ really means?

Today, I’m thrilled to welcome back Dr Robert Lustig, a leading public health authority who for many years has been trying to expose the truth behind the food industry and the many myths within modern medicine. Rob is Professor Emeritus of Paediatrics, Division of Endocrinology at the University of California, San Francisco He is the author of multiple books including Metabolical: The Truth About Processed Food and How it Poisons People and the Planet.

Robert first came onto my podcast back on episode 251 when we took a deep dive into what happens inside our bodies when we consume excess sugar. In today’s conversation, we do touch again on the impact of sugar on human health but the main focus is on the three different sites in the body where we deposit fat: subcutaneous (which you can see and feel); visceral (stress-related fat around the middle), and liver fat. It’s only the first of these that you’re likely to notice on the scales – but it’s the latter two, says Rob, that really determine your health.

We talk about why it’s stress not food that largely drives dangerous visceral - the fat that surrounds our organs - and Rob’s view that chronic stress underpins metabolic, mental, global and planetary health.

We also discuss

• how a minimally processed, wholefood diet can mitigate stress and weight gain
• why he’s not a fan of fructose, nor the glycaemic index
• why he thinks that continuous glucose monitors (CGM) can help the general population, not just those with diabetes
• why the liver may well be the body’s most important organ when it comes to metabolic health, and some of the key tests we can do to assess our own liver health
• And we also talk about alcohol, fruit, honey and many more topics that will help you make empowered decisions for you and your family’s health.

Rob’s work has changed many people’s lives around the world and his message deserves to be heard loud and clear. He is knowledgeable, passionate and someone who is not afraid to say what he thinks. I always enjoy talking to him, I hope you enjoy listening.

From the work of Italian researcher, Paolo Vanoli, who believes that the aggressive vaccine schedule and the mercury in vaccines can be attributed to men and women being altered and adapting to same sex relationships. to glucose and fructose altering a protein in the DNA, which regulates the production of testosterone and estrogen, we look at the variables and random factors that could be contributing to what many might consider to be a gender crisis.

SUGAR. It’s everywhere and in everything and in various guises. Fake sugar, artificial, refined, raw, natural, low calorie sweetener and table. Over 200 names for it exist. And if you google sugar and health you could be told it’s as innocuous as water or it’s as dangerous and as addictive as cocaine and worse than alcohol for your liver.

To get to the crux of what’s really going and how dangerous sugar is in our food system (and it’s artificial counterparts) I’m speaking with Professor Michael Goran - Professor of Pediatrics at Children’s Hospital of Los Angeles and Dr. Emily Ventura a nutrition educator, public health advocate, writer, and cook with a Masters in Public Health and Doctorate of Philosophy in Preventive Medicine. They’re also co-authors the fantastic book “Sugarproof” in which they explain the hidden danger that sugar poses to a child’s development and what options there are for parents and carers to mitigate sugar consumption.

Professor Michael Goran has also published over 350 peer-reviewed articles and reviews. He is the Editor of the “Childhood Obesity: Causes, Consequences and Intervention Approaches” published in 2017, co-editor of “Dietary Sugars and Health” published in late 2014, and currently serves as Editor- in-Chief for Pediatric Obesity. 

This is the podcast I’ve been asked to do so many times. So finally we can lift the lid on sugar and its impact. Listen to the end for my top tips and do check out the book Sugarproof on the podcast show notes

On the show today we talk about:

• Types of sugar and their various forms
• Why Artificial sweeteners could be just as problematic
• Why children are uniquely vulnerable to sugar
• How problems with sugar can be independent of weight
• Why sugar IS addictive
• Refined carbohydrates and how they can have similar effects
• Sugar, Inflammation and the brain
• The mechanisms of how sugar impacts the liver, behaviour and mood
• Policies to protect ourselves in the future
• Tips to lessen our sugar burden

Today's episode of The Qualys is from podcast #14 – Robert Lustig, M.D., M.S.L.: fructose, processed food, NAFLD, and changing the food system.

The Qualys is a subscriber-exclusive podcast, released Tuesday through Friday, and published exclusively on our private, subscriber-only podcast feed. Qualys is short-hand for “qualifying round,” which are typically the fastest laps driven in a race car—done before the race to determine starting position on the grid for race day. The Qualys are short (i.e., “fast”), typically less than ten minutes, and highlight the best questions, topics, and tactics discussed on The Drive.

Occasionally, we will also release an episode on the main podcast feed for non-subscribers, which is what you are listening to now.

In this episode, Rob Lustig — a researcher, an expert in fructose metabolism, and a former pediatric endocrinologist — discusses what’s wrong with the current food environment, and what we can do to reduce our chances of becoming part of the obesity, diabetes, metabolic syndrome, and nonalcoholic fatty liver disease (NAFLD) epidemics. Rob recently earned a Master of Studies in Law because he believes that educating people about sugar from a scientific standpoint is only half the equation: the other half involves changing policy, which he explains in this episode.

We discuss:

• What’s the difference between glucose and fructose? [7:00];
• Do we have biomarkers that can give us some indication of average exposure to fructose over a given period of time? [14:20];
• What’s the difference between ALT and AST? [18:45];
• Inflammation, endothelial function, and uric acid [21:30];
• Is there something that fructose does better than glucose? [23:45];
• For children that undergo a remarkable shift from metabolic health to metabolic derangement, is there a concern that these kids suffer an epigenetic hit that makes it harder for them later in life? [26:15];
• How many times do you have to introduce a savory food vs a sugary food to an infant before they will accept it? [29:30];
• How are alcohol and fructose similar in how they affect the brain? [33:51];
• Advice for parents and kids for creating a sustainable environment that's going to prevent them from running into metabolic problems [40:30];
• Why do some populations have a higher risk for NAFLD? [45:42];
• What causes NAFLD? [48:45];
• Is insulin resistance the result of NAFLD or is NAFLD the result of insulin resistance? [56:00];
• HRV, cortisol, and norepinephrine [1:00:30];
• What are the actual mechanisms that links metabolic syndrome, insulin resistance, fatty liver, and type 2 diabetes? [1:03:00];
• Is the food industry still saying that all calories contribute equally to adiposity and insulin resistance? [1:09:00];
• What is the difference between soluble and insoluble fiber and why do you need both? [1:13:00];
• How can we change the food system when 10 companies control almost 90 percent of the Calories we consume in the US? [1:15:00]; and
• More.
