Although this blog focuses on vaccines, there are really so many myths and tropes on the internet that are based on the misunderstanding of science, on pseudoscience, or just plain ignorance. One of those myths is that human meddling in plant genetics, which led to modern wheat, is the root cause of all gluten sensitivity, including celiac disease.
Of course, the quack medicine world has vastly overrated the “dangers” of gluten – those with real gluten issues, with properly diagnosed celiac disease and wheat allergies, represent less than 1% of the population. The internet quacks also have no understanding of real gluten sensitivity – it’s an on/off switch. With some relatively rare exceptions, gluten causes significant symptoms in those with gluten sensitivity, not vague feelings. And there’s no dose-response curve – a tiny amount has almost the same effect as a large amount of gluten.
Although I doubt it will have any effect on these anti-gluten food fads, a new peer-reviewed paper in a respected journal clear shows that that modern wheat is not responsible for celiac disease. Gluten from 2018 probably is the same as the gluten in wheat when it was first domesticated 12,000 years ago.
Let’s take a look at celiac disease, wheat, gluten, and the paper. I hope it makes sense. Continue reading “Celiac disease is not caused by modern wheat, despite internet claims”
I have never been a fan of dietary supplements pushed by Big Supplement, the less regulated, less evidence-based, more pseudoscientific mirror image of Big Pharma. Recently, a meta-review published in a respected journal examined whether there were any causal links between various dietary supplements and cardiovascular disease (CVD). They only found one, folic acid, that might have an effect on CVD, but, in that case, causality might not be so clear.
Just to be perfectly clear, no one on the side of real science-based medicine would dismiss using dietary supplements to treat chronic medical conditions. Many people have had surgeries, illnesses, and other medical conditions where certain supplements are necessary for the patient to survive. But these are highly specific requirements, not general quack claims that taking supplements will somehow miraculously treat colds and flues, prevent cancer, or some other nonsense.
Essentially, if you’re taking dietary supplements for no medical reason other than you believe it makes you healthier, let’s stick to facts – all that you are doing is having your kidneys create some very costly urine. Human physiology, based on a couple of billion years of evolution, automatically regulates its needs for micronutrients – excess amounts do not stick around to make you healthier, it just becomes a component of your pee.
It’s time to take a look at this article about dietary supplements and cardiovascular disease. Maybe I’ll convince you to save some money each month, and spend it on something like investing in a better diet. Continue reading “Dietary supplements make costly urine – not helpful for CVD”
Food fads make me want to scream, cry, and hide in a cabin in the mountains. MSG is safe. And high fructose corn syrup is just an awful name for sugar. And only a small number of people have a real gluten sensitivity. And now a new paper has caused the internet to explode with the trope that canola oil causes Alzheimer’s disease.
This new internet meme is based on a peer-reviewed article published in a real journal. But as I have written time and again, just because an article seems like it has sterling credentials, it doesn’t mean the article is above criticism. We’ll get to this article below.
As expected, all of the usual suspects in the pseudoscience world have jumped on board with clickbait headlines like, “Scientists finally issue warning against canola oil: Study reveals it is detrimental to brain health, contributes to dementia, causes weight gain.” I always find it ironic when a pseudoscience pushing website believes in scientists when it supports their belief.
Of course, we need to take a look at this whole issue. Here’s my spoiler alert (but please read the whole article) – there is little evidence that canola oil causes Alzheimer’s disease (AD) or dementia. You can use it safely. Continue reading “Canola oil causes Alzheimer’s disease? Dubious evidence”
As you probably would guess, when I read articles in science, I tend to emphasize research on vaccines, cancer, and a few other related issues. There’s so much information out there, one has to focus or there will not be enough time to watch college football games on Saturday. For years, one of the more popular questions I have seen is about sugar and cancer – does eating sugar cause or promote cancer?
A recent paper in Nature Communications seemed to encourage the people who are pushing an association between sugar and cancer. Of course, our usual suspects of pseudoscience and false healthcare jumped on board with their clickbait headlines trying to scare everyone about sugar and cancer.
But what are the facts about sugar and cancer. Should you avoid eating a diet high in sugar and carbohydrates? Well, probably, but not because of cancer.
That’s why we are here. To separate the science from the pseudoscience, we need to look at this more carefully. What we’re going to see is that you’re not going to get cancer from putting a couple of teaspoons of it in your coffee. And you’re not going to cure cancer by avoid sugar. Sugar and cancer is much more complicated than that. Continue reading “Sugar and cancer – examining the science behind the claims”
I wrote an article about how to critically analyze pseudoscience and misinformation so that you might skeptically analyze evidence supporting a claim, even if it appeared to be accurate. On Facebook, Twitter and many internet sites (including Wikipedia), there is an amazing tendency of individuals to accept what is written as “the truth” without spending the effort to determine if what is written is based on accurate science.
But if you’re going to make an extraordinary claim, like bananas prevent cancer, you’re going to have to provide extraordinary evidence. And if you’re going to push a pseudoscientific claim, please read what you claim as evidence. Because we have a case here, where the evidence isn’t even in the same universe as the claims.

Coffee is one of the most consumed beverages worldwide, with tea being number one. And as I have mentioned previously, I am an unrepentant coffee lover. Over the years, there have been a number of claims about coffee health effects, both positive and negative, many without any solid scientific evidence in support.
Claims about coffee health effects goes back centuries. These claims were often confusing and contradictory. How many “studies” have we read about that said drinking it was good for your heart. Or bad for your heart. Or it prevented cancer. Or it increased your risk of cancer.
Part of the confusion is that the popular press, with its strange dependence on false equivalence, often presents two contradictory scientific studies as equivalent, even if they aren’t. Well, we’re going to look at a powerful new study that examined health outcomes that can be related to coffee. Let’s see what they say. Continue reading “Coffee health effects – what does the best science say”
Every year, on the fourth Thursday in November, the United States celebrates a holiday called Thanksgiving. Part of the tradition, along with watching football (the American version), is eating mountains of food, including a roasted turkey. And this is where Uncle George regales the guests with the turkey tryptophan myth – that is, eating a mountain of turkey, which he claims is high in tryptophan, makes you sleepy.
Because I know the average reader of this blog is pro-science and snarky, I post this article for you to embarrass Uncle George. Well, he’s probably a Trump supporter who wouldn’t know any science because it isn’t a pedophile in Alabama. Oh sorry, I did go there.
Back to Thanksgiving and the turkey tryptophan myth. Only a few countries celebrate Thanksgiving, and just a handful of countries eat turkey in any amount, other than the USA and Canada. Surprisingly, 87% of English holiday dinners will include turkey, a bird that is native to North America. So, I guess when gobby Uncle George (loyal Chelsea football fan) starts with the turkey tryptophan tosh, you can tell him to bugger off with this article.
Just in case you want to impress friends and family, the other places that celebrate Thanksgiving, similar to the USA and Canada, are Liberia (which is populated by descendants of freed slaves who returned to Africa from the US), Grenada (a small English-speaking island in the Caribbean), Puerto Rico (a Spanish-speaking territory of the USA), and Norfolk Island, an Australian territory of like 1500 people. The only thing I thought that was on Norfolk Island was the Norfolk Island pine. And now I wonder if they import turkeys for the dinner.
For Americans, the holiday celebrates white English settlers arriving in North America. The tales usually include some peaceful sharing of food between the white settlers and native Americans (a nice myth without much actual historical support) prior to the first winter. Canada’s backstory on Thanksgiving is much more complicated, including ships getting stuck in ice and other legends – it is very Canadian.
In both Canada and the USA, the celebration includes tonnes of food (per person) usually including a roast turkey. Other foods may include mashed potatoes, yams (sweet potatoes), other meats, pies, corn, stuffing, and more food. It is a high calorie meal of epic portions!
Generally, everyone, after finishing this dinner, would want to take a long nap. Thus, we find the origin stories of the turkey tryptophan math. However, the science of eating, sleeping, turkey and tryptophan doesn’t support this myth. Not even close.

Gluten free diets, for about 99% of the population, are a pseudoscientific food fad that has captured the guts of those who consume any food quackery that makes the rounds. However, for those who have a medically diagnosed gluten sensitivity, there is good news – some new strains of wheat will produce a genetically modified gluten that may not trigger a gluten sensitivity.
Let’s wrap our mind around that – genetically modified gluten. I’m sure that won’t be problematic for those who have medically diagnosed issues with gluten. They’re going to be thrilled that they can eat real bread, pizza or pasta. I’m sure they’re not going to be concerned with any label that says “GMO foods here.”
Of course, the real scientific consensus about GMOs is that they are safe for humans, animals and the environment. And provide humans with more and healthier food. Like genetically modified gluten in wheat.
On the other hand, I’m certain (but I have no scientific evidence) that the Venn diagrams of those who buy into the nonsense about GMOs also buy into the pseudoscience of gluten. Those people might fall over from confusion.
Let’s take a look at gluten, the real medical issues of gluten sensitivity, and then what is this new genetically modified gluten in wheat. Continue reading “Genetically modified gluten – delicious and tasty irony”
The internet claims that high fructose corn syrup causes diabetes and a bunch of other maladies. Usually based on some weak evidence, the usual suspects have tried to link high fructose corn syrup (HFCS) to Type 2 diabetes.
Like many of these medical myths, there is, at its core, some tiny bit of evidence that is generally misinterpreted or misused. But let’s take a close look at Type 2 diabetes, HFCS and the evidence that either supports or refutes the hypothesis that drinking HFCS is any more responsible for the disease than other sugars. Continue reading “High fructose corn syrup causes diabetes – what is the evidence?”
The low gluten diet craze has got to be one of the most frustrating fads that have hit the developed world in the last few decades. Without real evidence that gluten affects anyone but the tiny percentage with a genuine, diagnosed gluten sensitivity, pseudoscience supporters are pushing a low gluten diet to treat any number of issues.
The only benefit of the low gluten diet is that today a lot of products are labeled “gluten free.” Thus, the few individuals who have real gluten sensitivity have an easier time shopping for safe foods.
So a low gluten diet may have few benefits for the 99% or more of the population. But does it have risks? Well, a new study seems to indicate that it does, and we’ll let the feathery dinosaur have a go at it. Continue reading “Low gluten diet – evidence of link to type 2 diabetes”
