Food additives are one of the most passionate issues amongst people who eat (which would be everyone). Aspartame. High 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
