I'm Dr. Andrea Love, biomedical scientist.

At Away From The Keys wants to know, how do you define pseudoscience?

So pseudoscience refers to beliefs or practices that appear scientific on the surface, but they lack the repeatability, the reliability, or the credibility of science.

Often they're making claims that are based on anecdotes as opposed to evidence.

They often start with a nugget of truth and then widely exaggerate that beyond what reality would indicate.

At Shanny X Ray wants to know, should I buy this flat tummy T or nah?

I hate to break it to you that these things are really just glorified laxatives.

So what's happening is that you're speeding up your digestive process beyond what it should be normally, but what you're flushing out is food that you haven't finished digesting properly and absorbing their nutrients.

So you're creating a lot of diarrhea and you're also dehydrating yourself.

So while you might feel like you have a very flat tummy, it's not because you're actually losing weight or removing toxins, it's simply because you've removed food too quickly from your body and you're dehydrating yourself.

At It's Synecdoche is asking, why am I only just learning that chiropractors are not real doctors?

So chiropractic is a $15 billion industry and it was invented by a guy named D.D.

Palmer who thought that ghosts were telling him to create it.

They believe that the joints and the nerves that go through our body are the cause of every ailment that we know of.

Unfortunately, chiropractic is a full-on pseudoscience.

There are certain chiropractors that maybe stay in the lane of more physical therapy and there's a little bit of data to suggest that for certain types of low back pain, chiropractic adjustment can offer temporary relief, but it's not fixing a musculoskeletal problem and it's definitely not doing the other things that chiropractors claim to do.

So if you see the abbreviation DC after someone's name on social media, that means that they're a chiropractor and they're not a medical or scientific expert.

At PathogenFlock, is it just me or is belief in pseudoscience rising recently?

We have seen a dramatic rise in anti-science and pseudoscience beliefs and this does trend with the prevalence of social media.

Also coincides with the recent COVID-19 pandemic and the increasing amount of politicization of vaccines.

So this past year, only 93.1% of entering school age children received vaccinations for the MMR, the measles, mumps and rubella vaccine.

This is a 2% drop compared to the previous school year, particularly for a disease where you need at least 95% coverage to stop the spread of measles.

At GutsNotGuts wants to know, how the fuck did the vaccines cause autism myth even start?

This myth started in 1998 because of a British gastroenterologist named Andrew Wakefield, who has since lost his medical license and the ability to practice medicine.

But he published a paper in the Lancet, which is a very prestigious medical journal and claimed that he had data to demonstrate a link between the MMR vaccine, which is the measles, mumps and rubella vaccine and autism symptoms in children.

The problem was he falsified all of the data in that paper.

More than that, he used self reports from parents who were planning to sue the existing manufacturers of the MMR vaccine.

On top of that, he was trying to sell and market his own MMR vaccine, but because it was published in such prestigious medical journal, it took the world by storm.

Eventually that paper was retracted, but that retraction did not occur until 2010, 12 years later.

Now in recent years, we're seeing measles rates above what we have ever seen in the US and it is really a cause for concern because the very first measles vaccine was put on the market in 1963.

So we have over 60 years of data that demonstrate that there is no relationship between vaccines and autism.

At Briny for Trump, GMOs change our DNA every day and give people several diseases.

In the 1980s and 1990s, the papaya was being wiped out by a virus called the papaya ring spot virus.

So we created a GMO papaya that can resist the papaya ring spot virus. 90% of the papayas are GMO and when you eat them, it is not changing your DNA.

So when you eat the papaya, you're eating all of its cells and all of those cells contain DNA.

So those DNA molecules are going to enter your stomach and it's gonna mix with an enzyme called pepsin.

So when the pepsin interacts with the DNA molecule, it blasts it apart into all of these individual subunits and therefore the DNA is no longer intact.

It's not gonna cause any harmful consequences.

At JohnnyV45385760 wants to know, how can you tell if a health influencer is legit or full of shit?

Some of the red flags to look for are, number one, they are trying to evoke very strong negative emotions, things like fear, anxiety, or worry, particularly as it relates to your health or the health of your children or your family.

Number two, they're making all or none statements.

They're saying that this thing is causing cancer or this thing is going to fix some disorder.

Number three, if they're selling you something that is related to the claims that they're making, whether that is a supplement or a diet plan or a protocol or a book.

Number four, if they have an obvious conflict of interest, are they working for the company of the product that they're selling you?

And last but not least, if they're speaking way outside of their area of expertise, if someone is a neuroscientist that specializes in optic nerve signaling and they're pretending to be an expert in infectious disease immunology, that's probably a red flag.

At 10,000 Problems wants to know, why does homeopathic medicine work so much better than real medicine?

Unfortunately, that is not the case, but let me tell you a little bit about what homeopathy is because it's often confused with other sorts of alternative remedies.

Homeopathy is a pseudoscience that was created or invented in the 1700s by a German guy named Samuel Hahnemann.

The first is that like cures like, meaning that if something causes a symptom, that same substance can cure an ailment that creates that symptom.

Onion causes watery eyes when you cut it.

Therefore, homeopathic onion is going to cure things like allergies that also cause watery eyes.

But that goes along with the second belief or the law of infinitesimals, meaning that the remedy becomes more potent the more it is diluted.

If you find a label on a homeopathic remedy that says 12C, C means 100 and 12 means that you've diluted the substance. 12 times 100 fold over, which means you have one part in this many parts, which is also called one septillion.

So what that means is that there's no actual active ingredient in that.

That is probably a good thing because there are many homeopathic remedies that can be very dangerous if you would ingest them at normal dosage.

For example, teething tablets that claim to have homeopathic belladonna, which is deadly nightshade, were contaminated with measurable levels of belladonna and hundreds of babies developed seizures and at least 10 babies died.

This happened starting in 2010 and 2012 and there were several brands that were to blame.

One final danger of homeopathy is that many people believe that they're taking something that's beneficial and beyond the fact that it is nothing more than a sugar pill, it often leads people to forego actual medical care, which is one of the biggest harms of all.

At Paulmetta555 asks, are cell phone towers detrimental to our health?

Why the spike in cancer rates since they arrived?

You have this primary node that's coming out from all sides and you have these radio waves that are being emitted.

You also have these secondary nodes that are a little bit smaller, but all of these radio frequency waves are projected in every direction because otherwise we wouldn't have cell reception.

So this myth kind of started because people heard the word radio frequency radiation and got scared because we know that there are certain types of radiation that are linked to cancer.

Here we have the electromagnetic spectrum.

Things on this end are very high energy and this rainbow right here is our visible light spectrum.

Ultraviolet and above, these types of radiation can potentially damage our cells and our body and can lead to changes in our cells and mutations.

But when you get below the energy level of visible light and you get into infrared and microwaves, way down here, those are your radio waves.

So this radio frequency radiation is one of the lowest energy types of radiation and it's considered what we call non-ionizing, meaning it cannot penetrate your body.

So even if those radio waves are all over our planet because we have cell reception everywhere, the amount of energy that they're exerting is not actually going to damage your body or cause you any potential harm.

At John Peterson FW wants to know, I'd really like to know from someone that actually knows if buying organic food for double the price is actually worth it slash better for you.

The biggest misconception is that organic is pesticide free.

They are grown using organic pesticides and organic pesticides are simply chemicals that have not been synthetically altered from the original state in which they exist somewhere in nature.

In contrast, these are conventional blueberries who were grown using conventional pesticides.

Conventional pesticides are those that can be synthetically altered in order to improve their specificity.

A 2010 study in PLOS ONE was looking at six different pesticides that are used to control aphids on soybean plants.

It was found to not only control aphids, but it also killed the natural predators of the aphids, the insidious flower bug and the Asian lady beetle, having a more broad negative ecological impact.

Another misconception about all produce is that they have all these residues of pesticides on them.

We're talking about parts per trillion, parts per billion.

If you're very concerned about it, absolutely wash your produce in water, but aside from that, you don't need to be stressing about your produce.

At Toya Rochelle wants to know, what do people think they're cleansing when they do juice and smoothie cleanses or detoxes?

I hate to break it to you, if you have functioning organ systems, you're already detoxing all day, every day.

So when people say that they're doing a parasite cleanse or a cleanse and they're claiming that these stringy things in their poop is parasite parts, what they're actually seeing is mucus and sloughed off intestinal cells, which is not a good thing.
