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...

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...

Why Your Brain Needs Fat
By Andy Hendel

That which sets us apart from our animal cousins, the thing that most differentiates us as humans, as Homo sapiens sapiens, is our outsized brain — a brain that’s capable of abstraction and higher-order learning and philosophizing, a metabolically white-hot, energy-devouring machine. And it’s mostly made of fat. The human brain is nearly 60% fat by total weight, and that big, powerful brain needs to be provided with certain types of fats (both saturated and unsaturated) throughout life to provide a balance of structural integrity and fluidity to its cells.


By and large, we get these fats from our diets, and what we eat gets incorporated directly into the membranes of the cel...

Meat guidelines – the evidence
By Andy Hendel






Executive summary


* Six papers about red and processed meat were published in the Annals of Internal Medicine on 30th September 2019. The first was a summary paper about dietary guidelines. The second was a systematic review of randomised controlled trials. There were three systematic reviews and meta-analyses of cohort (observational) studies and one final paper on attitudes towards eating meat.


* The summary recommendations were that adults should continue current unprocessed and processed red meat consumption, although the recommendations were reported as weak and based on low-certainty evidence.


* The summary paper noted that current guidelines are based on observational studies and that t...
