Why Antioxidant Supplements Don't Work, Part 2
By Andy Hendel

In the first installment, we reviewed what free radicals are, how antioxidants work, and why they often fail to deliver health benefits. Many brilliant people, including Linus Pauling, thought they had discovered the fountain of youth in antioxidants. When scientists hold beliefs that are contradicted by observation, it’s call for further investigation — even if those people have been awarded a Nobel prize.


Stress Makes Us Strong


Free radicals can go off like a bottle rocket inside your cells and wreak havoc. But that’s not the whole story. Reactive oxygen species (ROS, a type of free radical) are also a byproduct of energy metabolism. They’re inescapable, and evolution...

Insulin Therapy Increases Cardiovascular Risk in Type 2 Diabetes
By Andy Hendel



Question
How does insulin therapy (i.e., use of exogenous insulin) affect heart disease risk in persons with Type 2 diabetes?
Takeaway
This 2017 review provides a variety of evidence indicating the use of exogenous insulin increases both heart disease risk and overall mortality in Type 2 diabetics. This indicates use of insulin therapy should be discouraged unless absolutely necessary, particularly given the existence of alternative pharmaceutical and lifestyle tools to establish glycemic control without the use of insulin. More broadly, this evidence is consistent with the assertion (previously explored on CrossFit.com) that hyperinsulinemia directly increases morbidity and mortality and thus ...

In a version of a talk he has delivered during grand rounds at medical schools around the country, CrossFit Founder Greg Glassman divides various common causes of death into five categories: chronic, microbic, genetic, kinetic, or toxic.



The chronic disease category includes conditions such as obesity, heart disease, diabetes, stroke, hypertension, and kidney disease. Microbic deaths are caused by things like ebola, malaria, and SARS-CoV-2, the virus behind the COVID-19 outbreak. The genetic cat...

Why Antioxidant Supplements Don't Work, Part 1
By Andy Hendel

Free radicals are extremely reactive molecules that can damage cell membranes, organelles, and DNA. Their destructive effects within the body make them an obvious target for therapeutic treatments. The most common types are reactive oxygen species (ROS), such as superoxide and hydrogen peroxide, and reactive nitrogen species (RNS), such as peroxynitrite. Free radicals are unstable because they have an unpaired electron. They become stable by stealing an electron from a nearby molecule. That molecule will then grab an electron from another nearby molecule, and a chain reaction ensues. Ideally, a free radical will come in contact with an antioxidant molecule before it can cause any damage. Ant...

Lifestyle Tips to Hedge Against Respiratory Illness
By Andy Hendel

A version of this piece was published in the print edition of the U.K.’s Sunday Express on March 22, 2020, under the title, “COVID – 19 and the Elephant in the Room; an Opportunity to Get Fitter, Stronger, and Healthier.”


Years ago while working as a junior doctor, I suffered the worst bout of flu I could imagine. With a high fever and cough, it took me a week before I was able to get out of bed and six weeks before I felt back to having normal strength and energy. Retrospectively, there were three things that I ascertained leading up to becoming sick that made what should have been a relatively mild illness much more debilitating. First, I was particularly stressed th...
