People frequently want the easy way to correct their health issues. They want to imbue a magical quality to “natural” products to make themselves healthier. They don’t want to take one of those evil Big Pharma drugs. For example, over the past few years, Big Supplement has pushed a belief that cinnamon for diabetes is a great treatment.
But really, do these supplements actually do all that much? Well, the real scientific evidence gives little support to the health benefits of these various supplements. I’ve probably written over 50 articles on supplements, and maybe one supplement has any value in health.
Look at cancer prevention. There really are only a handful of ways to prevent cancer, and none of them include megadoses (or even single doses) of supplements.
We probably see a million advertisements for supplements and “natural” foods that make you thinner, healthier, smarter, stronger, better. Of course, if even 1% of the claims (or outright fabrications) made by these hawkers were supported by real science, we could close down Big Pharma and all those physicians hawking those evil drugs that aren’t necessary.
Except, we know that’s not true. And it’s time to look at the claims of cinnamon for diabetes – what is the real science.

If you are a regular reader of this blog, you know I’m not exactly a fan of vitamin supplements. They are expensive, and they don’t do what people want to believe they do. They do not reduce the risk of any cancer. They do not improve bone health. But I always forget to mention an important exception – prenatal vitamins and supplements that are well known to improve pregnancy outcomes.
And now it’s time for me correct this egregious oversight on the part of the feathered dinosaur’s body of work on supplements. Just to be clear, I always state an important caveat on my dismissing the usefulness of vitamins and supplements – those individuals with chronic disease or malnutrition may require supplements. For example, if you never touch a fruit or vegetable, you will probably need vitamin C to prevent scurvy. No, I didn’t say that vitamin C will prevent cancer, but it will prevent one disease.
Recently, a top peer-reviewed journal has published an article where the researchers showed that there was a lower risk of autism spectrum disorders in children of mothers who took prenatal vitamins. And I can write about one area of healthcare where some vitamins and supplements do have some value. This is more evidence that there are numerous issues that may lead to autism spectrum disorders – and it’s not vaccines.

So you’ve decided to forsake the flu vaccine because you buy into the easily-debunked myths of the anti-vaccine world. Then you catch the flu, which is considered a very dangerous disease despite some of the myths. Then, you send someone to go down to the local drug store to find one of those advertised flu treatments. It’s time to look at these common “flu treatments” and determine whether there is any scientific evidence supporting their usefulness.
I’ve written previously about various supplements and treatments for the common cold, and they mostly don’t work. Or the evidence is so weak that it’s a waste of money to use them.
These ineffective treatments exist for one reason – money. Common cold and flu treatments are a significant part of the estimated global US$278 billion supplement and nutraceutical industry. And the industry is largely unregulated, so they can make unsupported claims, and people buy them based on the woo.
Let me be frank – your best, and really, only choice to prevent the flu is getting the seasonal flu vaccine. It is the only method to boost your or your children’s immune system against the flu.
Although there’s some overlap between common cold and flu treatments, there are a large number of flu treatments that get sold over the counter, although one is sold by prescription. Are any effective? Let’s find out. Continue reading “Flu treatments – do any of them work, or should I just get the vaccine?”
It’s that time of year when dozens of common cold treatments are all over the place. On TV advertisements. On displays in your pharmacy. Once again, it’s time to take a look at these lotions and potions to determine which work and which are complete pseudoscientific nonsense.
There are literally a dozen or more homeopathic, herbal, and other unproven concoctions to prevent or treat the common cold, caused by rhinovirus. These common cold treatments are a significant part of the estimated global US$278 billion supplement and nutraceutical industry.
These alternative medicine – so named because there is no scientific evidence supporting their efficacy, let alone safety – products make claims that are so wonderful, many people take them. Then they themselves tell their friends how fast they got rid of their cold. Or that their cold wasn’t as bad after taking the supplement.
Essentially, the whole industry is mostly based on anecdotes, untested claims and the placebo effect. Colds are self-limiting infections, meaning an infection generally lasts some random amount of time, with most people recovering within 7-10 days.
We’re going to review some of the most well-known common cold treatments (there isn’t enough time to review them all), along with what real science says about them in high quality systematic reviews in peer-reviewed, high impact medical journals. This article will review all of the common cold treatments that seem to be out there. Spoiler alert – most don’t work.
One major problem is that the determination of the length and severity of the course of the common cold is entirely subjective. Since the disease is rather mild with few serious complications, it’s hard to determine when it exactly stopped and started, and how bad it was. So, positive results, if they exist, should be treated with a high degree of skepticism. Continue reading “Common cold treatments – what works, what is just plain nonsense”
One of the frequently made claims from the alternative medicine world is that vitamin C prevents cancer. Or cures cancer. Or does something with cancer. But what is the science behind vitamin C and cancer?
Of course, there are over 200-250 different cancers, each with a different etiology, pathophysiology and prognosis, so it’s rather incredible to believe that vitamin C has that much effect on any of those cancers. But the claims, and its adherents, persist despite the lack of robust evidence supporting these claims.
Frankly, there are just a handful of ways to prevent cancer. One of those ways, eat a balanced diet, implies consuming appropriate amounts of nutrients, like vitamin C I suppose. But does it mean that taking a handful of vitamin C tablets has some beneficial effect on cancer prevention or treatment? Well, let’s take a look. Continue reading “Vitamin C and cancer – scientific evidence says not much there”
As a vaccine supporter, I get accused of being a shill for Big Pharma all the time. My basement is filled with gold bars shipped to me in remuneration for my services to the corporate hooligans – wait. No basement, no gold bars. On the other hand, Big Supplement, those companies who make money off of people who think that if they take this one vitamin to prevent all cancer, makes a a ton of money selling this junk medicine to unwary and unsophisticated consumers.
Let’s take a moment and look at the differences between Big Pharma and Big Supplement. The former has to work hard and provide evidence of what its drugs do, while the latter basically can sit around and throw darts at various claims, then randomly assign those claims to some new or old supplement.
I have been skeptical of supplements for a long period of time. The supplements are generally of low quality, they don’t prevent or cure cancer, they don’t prevent colds, they can’t boost the immune system, and they don’t prevent heart disease. Now it’s the time to take a look at the benefits of omega 3 fish oil, something that is claimed by Big Supplement over and over. Is there anything there?
Unless one has a chronic disease or is chronically malnourished, there are precious few instances where supplements are necessary. A couple of cases where supplements may be critical include prenatal folic acid supplements to prevent neurological defects in the developing fetus and vitamin D supplements for individuals who do not produce enough endogenous vitamin D. However, just to keep this in perspective, excess folic acid for a long period of time may be correlated with increased rates of certain cancers.
The benefits of omega 3 fish oil has always been intriguing to me, because it is a supplement that I thought might be useful to improving health, especially cardiovascular health. Omega 3 fatty acids are generally found in fish, as it is produced by the phytoplankton that is the primary food source of much of the prey for larger fish and bio-accumulates up the food chain. However, for humans, there are other sources of omega 3 oils including walnuts and edible seeds, eggs, and other non-fish foods.
Epidemiological studies done in the late 1980s seem to indicate relatively low death rates due to cardiovascular disease in Inuit populations with high seafood consumption. These results began the rush to consume omega 3 supplements, and created a booming supplement industry.
However, since publication of those initial studies, much research has been done on seafood and heart disease. And the results don’t give much credence to the cardiovascular benefits of omega 3 fish oils as a useful supplement.

I have railed against charlatans who claim that they have the easy way to prevent or cure cancer. Generally, these snake oil salesmen try to convince you that they have some miraculous food, supplement, spiritual energy, and on and on, that can either kill cancer in its tracks. Or keep them from even growing in your body. But their claims are nearly always absent real compelling scientific evidence.
Like the trope supplements preventing cancer. They don’t. And that’s been shown in study after study after study after study (yeah, I could go on for awhile).
Or like avoiding GMO containing foods prevents cancer. Again, studies show that GMO foods have no effect on cancers. Oh, one more thing–bananas don’t have tumor necrosis factor, and the yellow fruit can’t prevent or cure cancer (but that doesn’t mean that they aren’t delicious).
Despite the absolute lack of evidence that supplements, kale, bananas, or drinking the pure waters of a glacial fed stream (which may not be an option with climate change), there are some things that can be done to reduce your risk (see what I did there–no absolutes, just management of risks) of cancer.
How to prevent cancer has been codified byThe World Health Organization (WHO) into 12 steps (no, not that debunked one) that is called the European Code Against Cancer.
Let’s take a look at cancer and the evidence-based ideas about cancer prevention.

Junk medical claims about vitamins are shouted from the rooftops of the internet, over and over. I can barely keep up with it. The claims about vitamin D seem to be trendy now. That means it’s time for vitamin D review – is it worth it, or is it a waste of your money?
Now, I don’t think vitamin D is worthless. It is an important micronutrient for human health, and if there’s a chronic deficiency, supplementation is necessary.
Proponents of megadoses of vitamins, called megavitamin therapy or orthomolecular medicine (pseudoscientific terms to sound like they are based on real science), seems to work on the unscientific belief that if a little helps, a whole boatload will help a lot more. Most of these ideas have been debunked and are considered quackery and fads.
I wanted to take a look at vitamin D, from it’s actual benefits to health to the possible dangers from supplementation.

If you’re a fan of the Dr. Oz show, you might have heard about his passionate support of green coffee beans, which are just unroasted coffee beans instead of the roasted ones we enjoy in a big mug, for losing weight. In America, weight loss pseudoscience, especially those who claim it’s “easy”, is an obsession, especially since since the country is experiencing an obesity epidemic.
Sadly, Americans are always seeking easy, simple, but effective ways to lose weight that don’t require them to change any behavior at all. In other words, let us eat our Big Macs and never exercise while taking a miracle pill, which makes us maintain a perfect Body Mass Index. If that existed, someone would make more money than the next iPhone.
But let’s focus on those green coffee beans.
