MSG myth – debunked with real science

msg myth

Food additives are one of the most passionate issues amongst people who eat (which would be everyone). AspartameHigh fructose corn syrup. GMO‘s. Salt. Sugar. Trans fats. Polysorbate 80. But the MSG myth is one of the most pervasive.

Of course, these additives cause angst in people because of their scary chemical names.

Obviously there is stuff, created by the beauty of natural sunlight and goddess blessed sweet waters from the alps, that is better than these man made evil chemicals. Well, no. Everything in nature is made up of “chemistry” –  25-hydroxyergocalciferol is a scary chemical name, right? Except it’s the metabolic product of the conversion of vitamin D in the human liver. It’s natural!

But let’s get back to MSG – how many times have you seen “No MSG” in a sign Chinese restaurant? Is it because China, who has been using MSG in their cuisine for centuries, has been conspiring against Americans since the first Chinese restaurant starting serving up kung pao chicken to unaware Americans?

It’s time to look at the MSG myth – is it real, or does it need a good debunking.

Dr. Oz falls for the overhyped and debunked GMO corn study

dr. oz

A few weeks ago, Gilles-Eric Séralini and his homeopathy loving coauthor published an article in Food and Chemical Toxicology that concluded that glyphosate (known as Roundup)-resistant NK603 GMO corn, developed by Monsanto, causes severe diseases such as tumors in rats. And usual anti-science websites bought into this nonsense, including the TV medical practitioner, Dr. Oz.

It’s time to remind everyone that the Séralini study was bogus, and that Dr. Oz is also bogus. Here we go.

Acidic blood causes cancer – time to demolish a myth

Acidic blood causes cancer

There are so many inaccurate, misleading, and harmful claims about cancer that I could spend years just debunking them. One of the most popular assertions is that acidic blood causes cancer – that is, if you lower the pH of the blood, it creates an environment to let cancer thrive.

Now, I’ve stated this about a hundred times on this blog (I am not kidding) – there are only a handful of scientifically sound methods to potentially lower your risk of cancer. Quit smoking is near the top. Stay out of the sun. Maintain a healthy (that is, very low) weight. Don’t drink alcohol. Get exercise. And a handful more.

And even if you do all of them, you just reduce your absolute risk, not completely eliminate it. You could randomly get a set of mutations – there are several trillion cells in the body, and even if genetic copying in cell division or transcription were 99.999% perfect, it still leaves millions of chances of mutations – that lead to cancer.

And then there are at least 200-250 different cancers, all with different causes, pathophysiologies, prognosis and treatments. In other words, even if you found some miracle way to prevent one cancer 100% of the time, it probably will have no effect on the other 200 or so cancers. We have tended to conflate cancer as one disease, when it is really a large set of diseases that have the same general physiology, but aren’t truly related.

Cancer is scary because it is so random. In many cases, the treatment is so harsh. And people are so interested in anything that may prevent cancer. And if it’s simple like “eat superfoods like kale and blueberries,” or “reduce acid in your blood,” the instinct is to try it out.

But let’s examine how and if acidic blood causes cancer. Spoiler alert – it doesn’t.

Science deniers use false equivalence to create fake debates

This article is #3 of the 12 most popular posts on Skeptical Raptor during 2015. This article discusses how science deniers employ false equivalence to create fake debates.

If you read a news article, Google a scientific topic, or watch TV, you’d think that some scientific principles were actually being debated by scientists. The unfiltered information about important scientific subjects allows the science deniers to use a false equivalence to make it appear that the often minority, and scientifically unsupported viewpoint is equivalent to the scientific consensus which is based on huge amounts of published evidence.

From listening to the screaming and yelling, you would think that scientists aren’t sure about evolution, vaccines, global warming, and the age of the earth (or even the age of the universe). There are even those who think there’s a debate that HIV doesn’t cause AIDS. It’s because some news sources think there’s a debate, so bring one person to represent one side, and one for the other, and the person screams the loudest often wins.

Whooping cough outbreak – science and simple math

I have written extensively about several whooping cough (Bordetella pertussis) outbreaks which had reached epidemic levels in areas like the Washington state, which had been considered one of the worst outbreaks in the USA during the past several decades. The outbreak has lead to several deaths here in the USA and in other countries such as the UK.

Of course, these outbreaks and epidemics have lead to the “blame game” from the antivaccination cult, because they have claimed that since A) most kids are vaccinated, and B) we’re having this outbreak, then C) either the vaccines are useless or are actually the cause of the outbreak. Seriously. They blame the vaccines.

There have been numerous reports about a whooping cough outbreak in the Reno County, KS area, with about 70 cases of the disease being reported. The report indicates that most of the kids who have the disease were vaccinated. It is unclear who said this, and what are the actual statistics. But for now, we’ll take this at face value.

Since this outbreak will undoubtedly lead to the typical antivaccine rhetoric about the whooping cough vaccines, DTaP or Tdap (which also protect against tetanus and diphtheria), I decided to search the internet to find the most popular vaccine denialist arguments regarding pertussis vaccinations–then debunk them. Hopefully, this will be useful for those who are observing what’s going on in Reno.

Water fluoridation myths – just another blog article

When I was a kid (probably 6 or 7), there was a big controversy in our community whether the water would be fluoridated or not. Now, I was just becoming fascinated by science, medicine, health, and sports at that time, so I tried to figure out what was happening.

To my ears and adolescent brain, the argument boiled down to no fluoridation (which meant cavities and visits to the dentist) vs. fluoridation (which was a communist conspiracy). Scary choices. Though Nazi dentists were also plenty scary.

But I grew up, and fluoridation became more common, as communities accepted the evidence that fluoridate water was safe, and improved the health of the community’s teeth. Water systems are mostly fluoridated (unless you drink bottled water).

And fluoride is in toothpaste and various mouthwashes. I thought the fluoridation controversy had passed into history with rotary phones, the Soviet Union, and the slide rule. My younger readers probably have never seen any of those three in their native states.

Now it’s time to look at those water fluoridation myths that can be found in many corners of the internet. Continue reading “Water fluoridation myths – just another blog article”

Pepsi and aspartame – an unscientific decision

Unless you’re a follower of the junk science presented by the pseudoscience shill, Joe Mercola and other crackpots, you probably didn’t think much of the artificial sweetener called aspartame (or by its more common trade name, Nutrasweet). You might have wondered if it was safe, but your skeptical mind probably rejected any safety issue not because most of the negative information came from bad sources–like Mercola.

Now that you’re here, reading this story, probably because you just read something about Pepsi and aspartame – because the giant soft drink bottler decided to remove it from their diet sodas. They did replace aspartame with–oh wait for it–two other artificial sweeteners. Obviously, Pepsi did it for marketing/public relations reasons, but the decision itself is based on bad information (on the internet, of course), rather than real science.

Cancer rates are increasing in the USA–another myth debunked

One of the enduring zombie tropes of the junk science world is that cancer rates are increasing in the USA (and across the world), and that deaths from cancers are higher today than it was in the past. Depending on the one screaming this myth, this rate of cancer increase is a result of A) vaccines, B) GMO crops, C) pasteurized milk, D) non-organic foods, or E) everything.

To be certain, there are a few things that do cause cancer, like smoking, UV radiation, human papillomavirus, and obesity. There are no 100% guaranteed environmental risks that cause cancer (lots of smokers do not get lung cancer, and there are very rare cases of non smokers getting the same cancer).

But are cancer rates increasing?

Here and there, you might run across a study that mentions one thing or another may or may not increase or reduce the risk of cancer. But most of those studies are one-off primary research, usually using small groups, providing little clinical evidence that you may or may not be able to increase or decrease the risk of cancer. Wait until we can find these studies in large systematic reviews, before deciding that this or that may or may not increase or decrease the risk of cancer.

In the meantime, Joe Mercola certainly can make boatloads of money making such nonsense cancer claims. If he were the only one, we could ignore him, but a quick search of the internet produces millions (I kid you not) of websites pushing miracle cancer cures or prevention.

Who are the most annoying antivaccination shills?

Please choose your favorite shill. Or not.

If you have remarks, comments or complaints, just put them in the comments at the bottom. If I missed a category, please tell me that, I’ll try to remember it for future polls.

Time to regulate the antivaccine liars out of existence, Part 1

Miracle-cureThis week, Dorit Rubinstein Reiss, Professor of Law at the University of California Hastings College of  the Law in San Francisco, guest wrote an article on this blog (and I’m grateful when she does) regarding the possibility of using the US Federal Trade Commission (FTC), whose principal mission is the promotion of consumer protection, to regulate or block antivaccine misinformation.

The process to request that the FTC investigate these individuals is relatively easy. And it’s time to change the discussion about vaccines, and make certain that those individuals who make money from lying about vaccines are blocked from doing so.

Pressure from pro-science/pro-vaccine on the Australian state of New South Wales led to an order that Meryl Dorey’s “Australian Vaccination Network (AVN)” must change its name since it “is likely to mislead the public in relation to the nature, objects or functions of AVN.” The core of the argument was that AVN was and continues to be strictly antivaccination, and it’s name seemed to imply it was something else.
