Knowing what you know, surely it's built up a bit of, I don't know, a bit of a, if I knew all that you knew, I think, about toxins in our environment, I would be, A, a really annoying person at like every dinner party, and B, there'd be a certain sense of, I guess, emergency and urgency to me, because I'd be looking around all my friends and I'd be, if I understood the consequences of them, drinking from that plastic container or putting that product on their face, I feel like I'm trying to be shouted at the world to tell them to stop. Do you feel a sense of that? You directly witnessed the impact that making these changes and detoxifying your environment had on you. Do you feel a sense of like, you know, ugh? Absolutely.

I mean, I can't even tell you how much passion it has ignited in me to be able to share this information and spread it as far and wide as possible because it's literally affecting every single person on this planet. And I do find it sometimes challenging not to call someone out and say, hey, be careful with that. But, you know, I think it comes from being a living example, and I've found that that is much more effective at being a living example. Instead of telling people, don't do this, don't do that, showing them what's possible. Look at what happened to me. Look at my journey.

Look at the benefit that I feel. And then once you start removing these things and making these simple swaps, it's about simple, small, incremental ships that anyone can do over the long term because it's really about it's a marathon, not a race. It's not about you've got to throw everything away and you've got to hide under a rock because I tried that and it didn't work and it caused more stress. And stress is harmful. So being a living example, empowering people with information, educating about the problem, but coming with a solution. You mentioned cancer is one of the downstream consequences of living in a toxic environment. And we talked about how sperm quality has reduced over the last couple of decades. When we look at the stats around cancer, are there any stats in particular that you think are most clearly associated with us living in such?

such a toxic environment. One of them that always brings to mind is breast cancer because I think I read or heard that breast cancer is on the rise or has been rising for the last couple of decades. And when you look at the Western world versus something like, you know, a tribe in Africa, they don't see the same levels of breast cancer. Yeah, that is definitely a concern because cancer historically was a disease of age, aging. It wasn't so common that you see cancer in your 30s, 40s, and even 50s. Now, we're seeing a shift, the window is moving earlier and earlier. Cancer incidents, like you said, breast cancer incident is definitely on the rise. I myself never knew anyone that suffered from

breast cancer or survived it until I hit my 30s. Then I knew five people that had it, including two people that I worked with in the toxicology lab. And what are your suspicions about the root causes of this rising cancer? I definitely think there is a huge environment mental component to it because a lot of what was believed decades ago was that disease and cancer incidents had to do with your genes. You were just genetically predisposed. You were unlucky. But in actuality, what we're seeing now is that the environment plays such a massive role in whether or not you actually have cancer. So just because you have the predisposition to developing breast cancer, such as the brachia gene, doesn't mean you'll get it.

It really depends on your lifestyle and how you lived, but also how your ancestors lived, right? We talked about the multi-generational effect of these chemicals, depending on how your ancestors lived, how your grandmother and how your mother lived, could predispose you to this. And have there been any studies that show the impact of these sort of everyday chemicals on cancer risk? Yes, and that's something that is, I don't want to say that it's excited. but I'm glad that we finally have proof. I don't want to see these studies. I hate seeing this, actually.

I'm really angry that people have to suffer with cancer because it's so preventable. There was a study recently that looked at removing certain ingredients from beauty and personal care products. So women without any history of breast cancer were asked to remove these ingredients from their products for 28 days. So that's very short. Four weeks, right?

They took cells from the breast tissue. They were all normal. They measured the amount of breast cancer gene expression. After 28 days, they took another sample. So after 28 days of removing these ingredients, they took another sample. And they saw that the breast cancer gene expression dropped. And the only thing that they were asked to change about their lifestyle was to remove these ingredients from their of personal care products.

And which products were they told to remove, and what ingredients were those? It was skin care, deodorant, shampoo, things that most people are using, and the ingredients were phthalates, which can often be found in fragrance. So the seemingly innocuous little term on the ingredients list, fragrance or parfou, can contain a huge number of chemicals. It's hidden behind this umbrella term because by law in Europe and in the U.S., manufacturers do not have to disclose this. It is considered trade secret. And within that chemical mixture are known carcinogens, endocrine disruptors like phthalates, and the most potent allergens known to man.

And with phthalates, the reason that they're in fragrances and that manufacturers love them so much is there what are known as film, warmers. So it helps the fragrance to stick to surfaces like your skin, your clothing, and it helps to make it last longer and linger. So if you've ever sprayed something on yourself and are still able to smell it hours later, that's a telltale sign that you've been exposed to phthalates, that you have thalates in that fragrance, in that product. And how many deodorants on the shelf have thalates in them? If it's got fragrance in it, almost all of them. It's code. It's code for endocrine disrupting thalates, essentially. You can assume that.

And in fact, it's safe to assume that they contain thallates. So, I mean, this is one of the deodorants that I often use. It's just a, I mean, for anyone that's just listening, it's just like one of the deodrants you'd find on a shelf in any store that comes in a little, is this an aluminium can? Yeah, it is, an aluminium can. Does this have phallates in it? How do I know?

So you just turn the container around and check the ingredients list. Do you see a word fragrance slash parfume? Yeah, fragrance, brackets, perfume. That's what you're looking for. Okay, so I shouldn't be spraying this all over my body. Right. Okay. So sometimes you'll see on there, it'll say, phthalate-free.

Okay. Right. That's helpful. But that still doesn't take away the fact that there are known carcinogens and allergens in there. So if you've got any kind of respiratory problems, any kind of skin problems, and you just don't want to expose yourself to unnecessary carcinogens, then it would be beneficial to avoid fragrance. What about a little spray?

Just a, pst. I mean, it depends. Is that really going to benefit you? Are you going to get any effect from that little spray? I don't want to smell. So this is why I spray this, because, you know, this drop is quite tight. So if it's tight and it's hot in here,

I'll end up smelling. So I just spray it, pst, and then it's public service for other people, really. I'm fine to smell myself. I can't even smell it, but it's for, you know, Jack and the team. Well, the question would be, can you find a safer alternative? And the answer is yes.

How do I find a safer alternative? What am I looking for? So you don't want fragrances. And you definitely, yes, so avoid the word fragrance unless it says that the fragrance comes from essential oils. Okay, but if it comes from essential oils, will it still make me smell nice? Yes. Okay. Yes. Because that's where aromatic compounds come from. They come from plants. But just to give you more context on this aerosol spray, this is one of the worst products that you can use. I've been using it every day. Yeah, so I'll tell you why.

Aerosols use propellants. Propelants are derived from petroleum, and there was a recall on thousands of products within the last couple years that the propellants were a source of benzene contamination, and benzene is a known human carcinogen, that you do not want to be inhaling. Because what you inhale goes to your brain,

it goes quickly all over your body through the bloodstream, you don't want to be delivering a known human carcinogen into your bloodstream. You're just not helping you at all. Because benzene is known to cause leukemia in people. So it's a no-brainer if you want to avoid that to avoid aerosols. But not only that, if you think about how you're actually applying the product, you're spraying it like this, right, in a stream and it heads towards your face. then that's also an inhalation risk

because there's particles in there. There's solids in there. You don't want to be inhaling unnecessary things. So the best option for deodorant is to look for something that has essential oils and is a roll-on or a stick, solid. Is there anything on the label that I can trust when it comes to deodorant?

Is there like a certain term that I'm looking for? You said phallate-free. Phallate-free. Is there anything else that? Yes, so thallate-free and paraben-free are definitely helpful. Okay. Because then we know at least two of the known endocrine disruptors

that we have evidence on are not found in that product. But that doesn't exonerate everything else. We still need to be diligent about the ingredients because they are sources of contamination, of byproducts, of carcinogens, and hidden toxins, essentially. It is pretty crazy that I could get a lighter and go, and it would be flammable. And then I spray that on my body,

like I'm lathering myself in petrol or something. It is pretty crazy. That's essentially what that is. Petrol? Yeah, because it's coming from petroleum, all of the propellants and some of the other base ingredients. I'm sure I haven't looked at it, but I'm almost certain because that is the source of the majority of ingredients

that go into these products. This is my last day ever using aerosol deodorants. Let's pull up a bin. Okay. Goodbye. Okay, that's gone. Okay, is this a better alternative? What I've got here is I've got this roll-on deodorant,

which I think is one of the refillable ones. Is this a better alternative? At least from this level of what I know of the fact that it's a solid, yes, but I have to see the ingredients list. We have to look at the ingredients list to really know what's actually in the deodorant. Okay. So at least from a sustainability standpoint,

that's definitely great to see, That it's not in a plastic container that is refillable, but we really need to check the ingredients. Okay, so I've got the ingredients list here. I've just pulled it up on my iPad. It says tapioca starch, baking soda, sunflower seed wax, coca seed butter, tochophenoral extate, no idea what that is, sterile alcohol, perfume. So do you recognize the ingredients? Are there? easily recognizable, or do they sound highly synthetic, very chemical-like? It says perfume.

Is there any indication on what's in the parfum? All our deodorants are scented with a blend of fragrances to give you the sense you love. Hmm. Is there any indication that it's thallate-free and paraben-free? Hmm. No. That's what should give us pause, is when we don't know what's in that fragrance term. That's really the issue.

Okay. I mean, there's just so many bloody words. Phallate-free deodorant. I've got a better way that I can help you search. Okay. If you just type in the word organic and then whatever product you're looking for, organic deodorant.

That is going to whittle down the choices significantly for you. You're saying that if it's organic, that means that it won't contain the phallates and the parabins. Not necessarily. This is where it gets a little. bit nuanced, but at least it whittles down the results that you'll get in search, and then you can check the ingredients one by one, and look for the one that has essential oils instead of the word fragrance, because it's really the lack of transparency that should make us pause.

We have no idea what's in there. We don't know what we're exposing ourselves to, and if you're someone who is concerned about the chemicals in the products you're using, the toxins you're being exposed to, if you are someone who is thinking about getting pregnant, are pregnant, breastfeeding, or just health conscious. And you don't want these toxins in your products, then this is the work that needs to be done. Interesting. So just because it's a role on doesn't necessarily mean it's safe. Right. Okay. Like you just demonstrated. And just because it's sustainable also doesn't mean it's safe. So there's a lot of marketing that goes on with products and, And manufacturers know that consumers are becoming savvy.

They're becoming aware and they're demanding safer products. So they will hit all of the buttons and hope that somebody isn't diligent and doesn't see through that. Is fragrance so important because fragrance is an indicator that it contains these fallates and parabins? Is that why I should be thinking fragrance is one indicator for whether the cosmetic product is toxic or not? Yeah, definitely. That would be probably the easiest and most obvious way that you can weed products out. It's just look for the word fragrance or barfume. And if there's no indication that it comes from plants, that it's from essential oils,

then that's not something that you want to use. I read a stat that said 91% of antiperspirants, 95% of shaving products, 83% of moisturizers and 63% of sunscreens contain fragrance. And 96% of shampoos, 98% of conditioners, 97% of hair styling products contain fragrance as well. Why are they putting fragrance and everything? Would the products not sell if there weren't fragrance in there? Yeah, I think there's many reasons that they put fragrances in. So, first of all, we are sensory beings, and people respond to fragrances.

Fragrances changes your mood. It uplifts your mood. It helps you feel more confident. Fragrances affect us on a very primal level. And the earlier and earlier that you can get hooked on fragrances, the better for these manufacturers, right? So that's why they're putting fragrances in even children's products. and scented everything. If you notice, I've got kids. We go out and look for slime. I said, let's look for unscented slime. It's nearly impossible to find it. You'd have to make your own

slime at home. So that's what we've started doing. And the kids love it because they get to, you know, be like little chemists or whatever. But you cannot find even, even they have markers, pens, crayons, they've got scented stickers. I mean, scented everything. Scent is everywhere now. the fragrance industry has absolutely exploded in the last 10 or 15 years. And fragrances are the most pervasive source, one of the most pervasive sources of toxins in our homes, in our daily lives. It's almost like the new secondhand smoke. That's how prevalent it is.

Because the chemicals, once you spray them, right, the reason you smell them is because they have volatileized means that they have become gases and they reach your nose. You smell them. What that also means is that they are in the air. Studies have shown that these fragrance chemicals, phallates, carcinogens, allergens, they bind to the dust in your home. So it's not like I smell this fragrance,

I sprayed it three hours ago, and I'm totally fine. Well, it's still in the air. It's always going to be in the air unless you physically remove the dust. So if you're not regularly dusting, mopping, sweeping, and vacuuming, you're becoming re-exposed. And this is absolutely the worst for a child, a baby who is crawling on the floor.

Their faces and noses and airways are close to the ground. So they're inhaling the dust that have settled on the floor. I don't know many people that are sweeping and dusting every single day. But if you have a child, then really, I really want you to listen to this. Because the child is putting stuff in their mouth. So they're ingesting these dust particles. They're ingesting the chemicals that are attached to the dust particles. They're inhaling them.

and they can't detox them. They can't detoxify them from their bodies. And so then what happens? They grow up. They start having allergies. They start having cognitive delays. They start having behavioral issues. They start storing more fat.

They can't lose weight. They have low energy, depression, and a host of conditions that we think are common, but doesn't mean they're normal and they're avoidable. That's the part that is so. important is that these conditions are avoidable. Before we start these podcasts, what we always do is we light some candles, and this is one of the candles that we light. You mentioned, I think you mentioned candles earlier on at the start of the conversation,

but what's your opinion on candles? Are they safe? It depends on what type of candle you have. There's basically a safer alternative for pretty much any product that you can think of. So I'm not one that says across the board, candles are toxic. It's very specific conventional candles, paraffin wax, scented candles, which is what you'll see in stores. The majority of candles out there are the ones that we shouldn't be burning. So this is a scented candle. It doesn't say what type of wax it is.

So we can be pretty certain that this is a paraffin wax candle, at least. using the precautionary principle, we should assume that something is guilty before it's proven innocent. So unless we know for sure that this is not a paraffin wax candle, I wouldn't light it. So because if I light it, then I'm pushing toxic chemicals into the air. Exactly. So conventional candles, there are five main reasons why I would not burn a conventional candle. Number one is that when you light those candles, they liberate carcinogens like benzene, talluline, and formaldehyde, but not only that, ultra-fine particles. Ultrifying particles are some of the most hazardous substances that you can create in your home. So ultra-fine particles are

tiny particles, less than 100 microns in diameter, excuse me, less than 0.1 microns in diameter, 100 nanometers, invisible to the human eye, tiny. And these particles have the ability to, as soon as you inhale them, they'll go into your brain. They have the ability to do that. They also have the ability to go as far down into the lung as one can go, all the way down to the alveoli. And down in those microscopic structures of the lung, that's where gas exchange happens. There's only one cell layer separating the outside from the inside. your bloodstream. One cell, that's pretty much nothing. That's pretty much no separation, no

protection. So if an ultrafine particle can get that down, far down into your lungs, it's guaranteed into your bloodstream. It's getting all over your body. It's causing inflammation and oxidative stress, which are the basis of many chronic diseases. So ultrifying particles, we need to avoid them as much as possible. And so one way is to not light a conventional candle. Number two is that they're also releasing volatile organic compounds, right? As I mentioned. Number three, they contain undisclosed fragrance. And within fragrance, there can be endocrine disruptors, carcinogens, and allergens. So when you like these candles, you're getting all of these toxins into your air. Number four, some of the dyes that are used to color candles are carcinogenic. And nobody has any

idea is if you burn them, what are the health effects of burning these carcinogenic dyes? And number five, candles are largely unregulated, which means that if you were to look at that candle and it says soy blend, there can be paraffin wax in there, even though it says soy blend. A lot of people think, soy blend, oh, it comes from soy, it must be healthier for me. So they'll go for that. But if it says soy blend, one should assume that it's a majority of petroleum-derived paraffin wax with a little bit of soy wax in there. because the consumer product safety commission, which regulates candles, doesn't look at the ingredients in the candle. They're concerned with the vessel, the container of the candle, whether or not it's fireproof, and whether or not the lead contains wood or the wick contains lead. They're not looking at what's in the wax, but studies have shown that when you light these candles, you are liberating a significant number of hazardous chemicals. So, we shall use incense instead. Incense is even worse. And I'm sorry to burst your bubble, but incense has been used for thousands of years.

But incense, as we know it now, is not the same as incense that was used a thousand years ago. They now contain, again, thallates, the endocrine disruptors, but also the ultrafine particles. And studies have shown that incense creates. more ultrafine particles in pollutants than cigarette smoke. There's an increased risk of cancer because these ultrafine particles are damaging DNA. Damaged DNA leads to mutations. Mutations can lead to cancer. There's an increased incidence of cancer in temple workers. So people who are around incense for hours upon hours at a time, there's an increased risk of cancer. Not only that, there's an increased risk of cancer, almost threefold, in children whose parents burned incense in the home.

Okay. Wow. Okay. So no incense. My house is going to stink. Well, you can use, there's different candles that you can use. So based on my research, I looked, I was really hell-bent on finding. What is the type of candle that has the lowest emissions, the least emissions? Because let's make it, I want to make it really clear. Anytime you burn something, that's not necessarily healthy. but does it mean that you can't do whatever? No. If you find a candle that is low emission like beeswax, essential oils, wooden or cotton wicks, then that's a much better alternative than your conventional paraffin wax scented candle, brightly colored. What you just listened to was a most replayed moment from a previous episode.
