Resveratrol Supplements. Trifling Facts. Lots of Conjecture.

Joe Schwarcz PhD — Thu, 02 Jul 2026 13:32:12 +0000

A quick online search for “resveratrol supplements” finds dozens produced by various companies. They contain anywhere from 50 to 500 mg resveratrol per capsule and sport labels that scream “source of antioxidants.” But there is no mention of any condition that resveratrol is expected to treat or prevent. For good reason! While there is plenty of speculation about what this compound can do based on laboratory experiments that use cell cultures, yeasts, worms, flies or rodents, it is best to remember that humans are not giant test tubes or colossal rodents.

Quackery in Quebec: The Trojan Horse Bill I Worry About

A new bill has been proposed at the National Assembly of Quebec, and while it may look like it will benefit our health, there is a lot going on under the surface. It is an excellent example of how the rebranding of pseudoscience gives it legitimacy, and this Trojan horse is now knocking on our legislative door.

Handling Receipts at the Supermarket

I was startled by the comment from the shopper just behind me at the checkout counter in the supermarket. “You really shouldn’t be doing that!” Noting the quizzical look on my face, a further clarification was obviously needed. “I mean you shouldn’t be handling the receipt,” she went on. Indeed, I had taken the thermal paper receipt from the cashier and without looking at it tossed it in with the groceries. I now understood my fellow shopper’s concern.

Blue Light Vs. Red Light

There is an epic fight unfolding between the light side and the dark side of, no, not the Force, but the light spectrum itself. You will have seen the countless gadgets claiming to heal you with red light—the creepy masks full of LEDs, the therapeutic light boxes, even the full-body infrared saunas. Red light, we are told, has health benefits.

Let’s Rap About Rapamycin

Easter Island in the Pacific off the coast of Chile is famous for the giant stone statues that were erected by natives some 500-700 years ago. The thinking is that the statues were designed to honour eminent ancestors by providing a home for their spirits to inhabit. In the 1960s, Easter Island made it into headlines for a totally different reason. Soil samples were found to contain Streptomyces hygroscopicus, a bacterium that produces a chemical with antifungal activity.

Aspartame: Not the Devil Incarnate but Not A Godsend Either

Joe Schwarcz PhD — Thu, 28 May 2026 23:43:46 +0000

Long before “wellness influencers” honed the art of spreading misinformation on the internet, the public was at the mercy of being befuddled by hoaxes through chain emails. Way back in the 1990s, I was the recipient of one of these from “Dr.” Betty Martini in which she described a speech given by one Nancy Markle at the “World Environmental Conference” in which she claimed that the artificial sweetener aspartame was the cause of multiple sclerosis, chronic fatigue syndrome, seizures, brain tumours, lupus and Alzheimer’s disease.

Exaggerated Fears Over Cancer Biopsies Can Worsen Cancer

Fear of the needle is not reserved to the vaccine hesitant; it extends to biopsies as well. In corners of social media where misinformation accumulates, influencers with an axe to grind against doctors are warning people to stay away from biopsies that help diagnose a cancer. “NEVER do a prostate biopsy, NEVER do a breast biopsy,” you will read, as the biopsy is said to spread the very cancer it is sampling.

Our Bodies Are Full of Dark Proteins. Can We Use Them Against Disease?

Jonathan Jarry M.Sc. — Thu, 21 May 2026 21:53:35 +0000

These proteins were not supposed to exist. Yet, there they were. As we started to learn more about them, researchers wondered if we hadn’t stumbled upon new targets for treating diseases like cancer.

If wellness fads abided by their own horoscope, we could say 2025 was the Year of the Protein. The macronutrient was shoved everywhere: inside of cereals, milk cartons, even pasta. Everyone wanted more protein.

But proteins are simply the building blocks of the human body. They make up much of the infrastructure of our cells’ cityscape. They make life possible.

The Science Behind the Quest for a Non-Peptide Oral Weight Loss Drug

Not only does it have a tongue-twisting name, “orforglipron” has a complex molecular structure that made its synthesis very challenging. A massive effort by chemists at the Eli Lilly pharmaceutical company finally resulted in a viable synthesis, but why this massive effort? Because the payoff also promises to be massive! Orforglipron is the first “small molecule” to act as an oral “GLP-1 agonist". Its discovery takes us on a long and winding journey.

My knowledge of anatomy is rather limited, so I wasn’t too surprised that I had never heard of the “multifidus” muscles that line the spinal column and have the task of supporting movement of the vertebrae. Neither had I heard of the “transversus abdominis” muscles in the abdomen that act as a natural corset, stabilizing the lumbar spine.
