Is Sugar Toxic?


Is sugar toxic? Professor Robert Lustig is perhaps the number one enemy of Big Sugar. His famous YouTube video “Sugar: The Bitter Truth” has been watched more than 6 million times.

In that video Lustig calls sugar toxic. So is it? Of course Dr. Lustig has had quite some pushback on that. Could sugar really be toxic? Isn’t it natural and part of the human diet since like forever?

In this interview, professor Robert Lustig explains it all. Watch a segment from it above (transcript). The full 30 minute interview is available on our member site:

Cutting Sugar Rapidly Improves Heart Health Markers

Sugar – not just empty calories

Can a simple dietary change – just eating less sugar – make children’s risk of heart disease take a quick nose dive? Possibly.

In a new study (by Prof. Robert Lustig among others) researchers made obese children have less sugar, without changing calorie intake or macronutrients. They only substituted starch for sugar.

What happened? A fat associated with heart disease, triglycerides, decreased by 33% and there were dramatic reductions of small, dense LDL cholesterol (another risk factor for heart disease). All in ten days:

This supports the idea that sugar is uniquely problematic when it comes to heart disease risk. But the study did not have a control group, so the findings have be taken with a grain of salt (this is not an RCT).

Still, getting these big reductions in heart disease risk factors just by eating less sugar and more of something else, without changing body weight, and in just 10 days… it’s hard to ignore.

“I Feel Better and My Head Feels Clearer”

Before and after

Rebecca became addicted to sugar already as a child, and since then it has been something that she has battled throughout her life. But it wasn’t until she read Bitten Jonsson’s book “The Sugar Bomb In Your Brain” (Swedish only) that she finally understood that she was a sugar addict.

Here’s how she at last came to find LCHF and the other tools to help her beat her addiction:

“Now Sugar Is the Bad Guy”

Untitled-3

Is fat or sugar the enemy when it comes to overcoming heart disease?

Last week, we wrote about an episode at CBC Radio that examined this question. Now it’s time for part 2, featuring experts such as Gary Taubes, Nina Teicholz and Dr. David Ludwig.

First, fat was the dietary bad guy. We were warned back in the 1980s to cut back on eggs, meat and full-fat dairy to avoid heart disease. So we started eating more bread, rice and pasta and fat-free snacks. But we got sicker and fatter. Now sugar is the bad guy. Contributor Jill Eisen explores the complex, and sometimes contradictory, science of nutrition — and tries to find clarity amidst the thicket of studies and ambiguous research.

Top 10 Fattest Countries in the World – 2016 List

Here’s the top 10 fattest countries in the world in 2016. The top of the list might surprise you:

Gazette Review: Top 10 Fattest Countries in the World – 2016 List

The number one country is Kuwait and number 2 is Saudi Arabia, and the list contains several other Muslim countries with hot climates. So why?

There’s a simple possible explanation. When it’s hot you need to drink a lot. And if you’re Muslim you’re not likely to drink alcohol. So what will it be? For many people it’s soda or other sugary drinks. The number one thing that makes people fat.

Fat vs. Sugar – Who’s the Villain in Heart Disease?

Untitled-3

Is fat or sugar the enemy when it comes to overcoming heart disease? CBC Radio examines this question in an episode, featuring experts such as Gary Taubes, Nina Teicholz and Dr. David Ludwig.

Even Professor Walter Willett at Harvard is coming around, saying this:

Saturated fat, interestingly, is not nearly the terrible villain that many people have made it to be.

The conclusion? Fat is not the villain, insulin is. It is the hormone that, in excess, is the number one predictor of heart disease according to the expert Barry Sears. And we all know what’s causing insulin secretion. Fat or sugar? It’s sugar.
