The Dark Side of Chocolate: As Heard in Lee and Irene's Wellness Unfiltered Podcast
Picture this, it’s three in the afternoon and the energy slump has just hit you like a tonne of bricks. You’re eyeing that "healthy" dark chocolate bar tucked away in your office drawer. But here’s the six-million-dollar question… is it truly a nutrient-packed superfood that lifts your gut health and mood, or is it just a sneaky chemical cocktail loaded with heavy metals, emulsifiers and stripped-out antioxidants that will leave you feeling worse in the long run?
I recently covered this question on episode 2 of my brand new podcast called Wellness Unfiltered with Irene Falcone (She’s the Founder of Clean Nectarine), and we peeled back the wrapper on the one-hundred-billion-dollar chocolate industry. From shocking lead scandals to gut-disrupting E-numbers lurking in plain sight, we uncovered why even those "clean" labels can mislead you completely. You can listen to the podcast on Substack Apple Podcasts, Spotify, YouTube.

If you’re as fed up as I am with health-washed snacks that leave you bloated and mentally foggy, read on as I share some of my latest insights. I’ve put together a no-nonsense roadmap to chocolate that I hope will give you some answers.
Chocolate is a topic that dominates everyone's WhatsApp group, every office kitchen, and definitely every woman's 3 p.m. slump, but have you ever stopped to think about cacao's it’s incredible origins?
Cacao (Theobroma cacao) is not just any treat; its name literally translates to "Food of the Gods" in Greek, a fitting tribute to its sacred role among the ancient Mayans and Aztecs. These clever civilisations did not mess around: they brewed cacao into a frothy, chilli-spiced drink for sacred rituals, healing remedies and yes, even as actual currency for trade. Those precious beans were worth their weight in gold or jade, and for good reason.
Fast forward to today, and premium cacao from single-origin hotspots like Ecuador's mineral-rich volcanic soils, Peru's lush biodiverse highlands or sustainable West African farms can still house magical soil which infuses the beans with complex, unforgettable flavours, just like a fine wine reflects its vineyard.
When it comes to chocolate, ethical sourcing is not just a trendy buzzword. It guarantees fair pay for hardworking farmers and cacao grown without the pesticides and heavy metals like cadmium. But sadly there’s a dark side of chocolate too and that is the mass-produced factory chocolate farms. This type of chocolate often comes from depleted soils that ramp up the level of contaminants in your 3pm snack.
Cacao vs. Cocoa: Why the spelling determines the health benefits
Raw, unroasted cacao is the real deal, preserving delicate enzymes and antioxidants that turn chocolate into a bona fide superfood. Roasted cocoa, on the other hand is not. The high-heat processing it is exposed to zaps many of the precious polyphenols and nutrients from the chocolate.
So why do we crave it so much? Have you ever wondered why chocolate feels like a warm hug in the middle of a stressful day? It is not sorcery; it is clever biology at work. Cacao floods your system with anandamide, the "bliss molecule", which locks onto your brain's cannabinoid receptors for that instant wave of calm. It’s nature's own mood elevator, delivering uplift without the dreaded crash. Then there is theobromine, a gentle stimulant that widens your blood vessels for steady, jitter-free energy, miles better than a harsh coffee hit.

I always suggest to my nutrition clients to choose raw or minimally processed cacao, to unlock a veritable treasure trove of goodness. One healthy mineral in cacao is magnesium, which powers hundreds of essential reactions in your body, from soothing tight muscles to melting away tension. Flavonoids, which are antioxidants can help to dial down inflammation, nurture healthy blood pressure and supercharge blood flow to your brain, banishing afternoon fog. Iron and zinc are fatigue-fighters and immunity levellers too, particularly if you are on a plant-based diet.
When it comes to gut health, the prebiotic fibre in cacao acts like fertiliser for your gut microbiome, encouraging regularity and a diverse bacterial strains that keeps everything humming along. Studies show high-cacao chocolate links to stronger heart health, sharper cognition and even better mood stability. Roasting keeps some perks alive, but the Dutch method, which is very common, obliterates most flavonoids, so that’s why choosing raw or naturally processed will give you better benefits.

Three Ingredient Chocolate Heart
Now back to the dark side of chocolate…
Brace yourself because this is where it gets a little worrisome. Recent lawsuits have blown the lid off lead and cadmium levels in big-name brands like Hershey's and Lindt, often traced back to polluted growing regions. As a nutritionist who has seen too many clients struggle with gut woes, emulsifiers like soy lecithin, E476 and PGPR set off alarm bells for me. They give that irresistible "melty" texture, sure, but they behave like detergent on your delicate gut lining, slowly eroding the protective mucus barrier and paving the way for bloating, irritable bowel flare-ups and leaky gut issues. PGPR, that petroleum-derived budget trick, just replaces pricier cocoa butter without a second thought.
Here is my golden rule of thumb: if you can’t pronounce an ingredient, maybe best to leave it on the shelf. Spot "alkalised"? That is secret code for “Kiss most antioxidants goodbye”. And sugar? The refined types can spike your blood glucose like a rocket. I personally swap it for gentler, lower-glycaemic choices like coconut nectar.
My Top 10: Clean Chocolates Ranked
I recently looked into which chocolate brands are available on supermarket and health food shelves, so I put a number of Australian-available bars through rigorous blind taste-tests and tests.
I ranked them by lowest sugar content (none or low-glycaemic index preferred), highest real cacao content (unroasted or raw for peak nutrients and antioxidants), rock-solid purity (zero emulsifiers or dodgy additives), irresistible flavour balance and those gut-loving bonuses like prebiotic fibre or live probiotics. The lower ranks? They slipped up with more sugar, skimpy cacao or questionable ingredient lists.

Below are the results and my personal ranking table.
Just a few nutritionist nerd notes;
Why does Om Bar pip Gutsii to second place? Its unroasted Ecuadorian cacao which locks in natural enzymes, the live probiotics deliver direct gut repair (unlike inulin's indirect feeding), and it melts silkier on the tongue without any harsh aftertaste.
Loco Love tops for creaminess, best tasting and I love the company and their ethical values.
Old Gold? It trails at the bottom with refined sugar and the strong chance of hidden emulsifiers lurking under Cadbury's broader standards. I have reached out to Cadbury to see whether it does contain emulsifiers (they are not currently listed on the ingredient label), and will let you know when/if I hear back from them.
The chocolate bars that are in the lower ranks reflect higher sugar, lower cacao, or less clean ingredients.
Here are my rankings:

How To Supercharge Your Chocolate Ritual
If you are a chocolate lover, I’d love to also offer you a few insider tips to make your chocolate moments even better.
- When it comes to reading labels, hunt for "unroasted" or "raw" to snag the highest antioxidants, while dodging anything "Dutch processed" or "processed with alkali".
- Time it right with an early afternoon square, letting theobromine work its magic without messing with your evening melatonin and sleep.
- For extra joy, melt it over fresh berries or nuts to amp up fibre and healthy fats, then pair with a soothing herbal tea.
- And storage? A cool, dark spot preserves those fragile flavonoids, or pop it in the fridge come humid Aussie summers.
Chocolate does not have to be a guilty pleasure, Superchargers. By ditching the factory fakes crammed with emulsifiers and embracing these high-purity, unroasted picks, you are treating yourself to genuine nourishment: stronger heart health, steadier moods and a happier microbiome.

[00:00] Intro
Irene: Well, hello out there. So, you're Lee and you're Irene. And together we're Wellness Unfiltered. Yay! Welcome, everybody. This is the very first episode of Wellness Unfiltered with Lee and Irene. And we are coming to you live from a very secret cabin location. And we are so glad to have you here with us.
Lee: Finally, Lee, we have been talking about doing this for years because I know we're both just so done. We are so done with the sugar coating, done with the greenwashing, and done with the wellness gaslighting.
Irene: Exactly. And this show is all killer and no filler and no hidden agendas either, because we just want to talk about the clinical facts. We're going to put in a bit of common sense and the unfiltered truth about what you're really putting in and also on your body.
Lee: So, this is going to be a weekly podcast on wellness and beauty, and we want to bring the heat to our industries too. We're going to shine a light on what's going to help you in your day-to-day life. You, our lovely listener. Irene and I and our unfiltered guests will bring you real, raw, and refreshingly honest chats about wellness, minus the woo woo.
Irene: You bet. And I've been told I don't have a filter. And I definitely have some thoughts on the world of beauty. And I also have some bones to pick and some myths to bust.
Lee: Together, we have a combined 30 years in health and wellness and beauty, especially the natural kind. We just love what we do so much. It's so dynamic and so interesting, and change is constant but so much fun. It sure is.
[05:20] Hosts' Introductions
Lee: So, I'd like to start with a little intro all about the force of nature that is sitting right alongside me. Drumroll, Miss Irene Falcone. So about 15 years ago, do you remember we met when we were both single parents, and we were kind of just trying to make ends meet? And back then, remember, you were working at Universal, and I was at ABC. Yeah. Of course.
Irene: And do you remember you used to send me those free movie tickets so Tamsin and I could go to the movies? I always used to give it a try. I always used to sneak my allocation to you. You did.
Lee: And I used to give you little music albums too. Sorry, Clive, if you're listening, that's my boss. We're still in touch, actually. Thanks, Clive. Thank you, Clive.
Irene: Back then, we were kind of just two young parents, weren't we, supporting each other through those pretty tough times? But fast forwarding onto today, I feel like we've really cheered each other on through wins and losses and everything in between. And we've both seen our dreams take shape. While I personally, you know, started blogging and I did my blog Supercharged Food and built my website Supercharge Your Gut, you went down another road and you became this amazing global entrepreneur, buying and selling major businesses, racking up every award and leading the way for ethical entrepreneurship.
Lee: I do remember actually, I was in Central Station one day and I was just waiting for my train, and I looked up and I saw this beautiful beaming face across a massive billboard in the station, and I thought, wow, that's you, Irene. And it was such a proud moment. Thank you for BWX for buying those billboards for me.
Irene: And fast forward to today, we actually genuinely just live around the corner from each other and we're still super close friends, which it really is a full circle moment, isn't it? It really is.
Lee: And I'm just, I just almost have to pinch myself when we think about how far we've come over the last 15 years. It's actually longer. I think it's more like 20 years now. Yeah, I feel like some friendships are just meant to be hard. And looking back on those really simple acts of kindness that we did back then when we were both struggling and building our businesses, and now we kind of help others live healthier, more conscious lives. And I don't know about you, but I definitely feel a big sense of achievement from that.
Irene: You know what's interesting? I don't know if I've ever told you this, but in that business that I started after I left Universal Pictures, you know you love your gut powder was my number one selling product. Was it? Yeah. At least 3 or 4 years in a row. Yeah. I remember we would just get these deliveries and we would. And I would tell the staff not to put it away on the shelf because I knew, just leave it out the front because I knew they would all get packed directly into orders. Oh, that's so awesome. I love how our friendship is so authentic and genuine. And boy has it stood the test of time.
Lee: Oh, Lee. So, what can I say about Lee? First and foremost, your blog. You had a blog, and it was back in, I'm going to say 2008 about then, and it was literally the only really good genuine food blog at the time. And I was obsessed. In fact, I was such a fangirl of this. And I would bookmark it, I would chop off it, I would cook off it. And it's really, I don't know if I've ever told you this, Lee, it was your blog that inspired me to start my blog. No, it really was. I thought, I need to do a blog similar to this, but on beauty products. And that's what made me start the Living Toxin Free, actually was Toxin Free back then, Living Toxin Free in the City, which ended up going on to become my first business. But you really were the inspiration for that, so thank you. Oh, I'm blushing. I need, I need one of your natural concealers. Can I borrow one? Yeah, yeah, I've got one in my bag. In my bag? Why don't you have one yet? Need one?
Irene: But beyond the blog, I think you have written ten, but I've gone to at least ten book launches shortly. Yeah, you have. In fact, I just handed in my 12th book. Wow. I mean, you are such an inspiration. Your books are amazing. I'm so proud of you. Oh. Thank you. That's such a sweet intro. I'm blushing. Oh, and one other thing about Lee that you might not know that I hope I'm allowed to say, but did you know Lee is actually a singer? She used to be a singer in a band. I actually walked past the ARI Awards on my way to the cabin. Awkward. I actually played congas in a band, the Love Monkeys, back, back in my heyday. You are a multi-faceted, multi-talented Virgo, Lee. I am definitely a Virgo.
[12:15] Episode Breakdown
Lee: So, here’s a breakdown of each episode. Each week we are going to take a dive into what's popping. So, the news, the views, and the controversies of the week in wellness and beauty. That's all on the top of our minds. That's right.
Irene: And we'll also help you help the man in your life with our Woman's Blame segment. So, let's be honest, many men are notoriously, let's say, strategically avoidant of their own health, right? Totally. They will research a car battery for six hours, but they won't take just a few minutes to look after their health.
Lee: So, every episode, we're just going to give you a few simple ideas to get your man a little healthier and looking his best. Then we are going to have a lovely listener zoom into the cabin with You're on Speaker. Oh, can't wait. Oh, and then we finish with my favorite segment, which is a rant or rave. Mostly I love the rant part of that. It's going to be so fun. Of course, unless you're doing something dodgy out there.
Irene: Well, I've always wanted to say this. So, without further ado, let's talk about what's popping.
[15:40] What's Popping: Sunscreen Discussion
Lee: So, we're kicking off our very first Wellness Unfiltered episode with our What's Popping segment with one of my very favorite guests so far. Hahaha. It's you! I really am a cheap guest. Well, you're also a true pioneer when it comes to natural ingredients and clean beauty.
Irene: And I really want to chat to you today about lifting the lid on something almost every single Australian person uses, and that is sunscreen. And lately it's been such a hot topic in the news. But it's also, I think, a really confusing one for people. Oh, it's super confusing. I've actually made a sunscreen before and the process is really complicated and there is a lot of red tape, and there's also a lot of confusion out there in the market.
Lee: Yeah, I do want to pick your brains today about natural ingredients as well. And I want to talk about transparency and beauty. And I might also have a few cheeky questions about the Australian regulatory landscape as well.
Irene: But yeah, we'll have another leading sunscreen expert coming on in a future episode too, which will be really good. So, we'll do a part two of this. But if you really want to know what's in the bottle and why some sunscreens have recently been taken off the shelves, and if you want to know how to choose products that protect both you, your skin, and the planet, I think this episode is going to be really illuminating. So, slip, slop, slap your headphones on and let's get into it.
Lee: What do you want to know, Lee? All right, well, firstly, just with a little bit of background, I actually had a melanoma a few years ago removed from my forehead, which was a super scary experience. And so that made me really aware of the harshness of our Australian sun and the need for us to wear sunscreen. What I want to know is there's been so much controversy around sunscreens lately, which you talk a lot about on your social media. Can you give me and your listeners a rundown on what's going on and what's the inside goss?
Irene: Oh, well, there's a few. There's a lot going on with sunscreens at the moment and oh, where do I start? I guess it all kicked off with this Choice story. It's like the X-Files. Yeah, it's a lot like the Epstein files, but for sunscreen. There's so much going on. So, Choice. I think they do it every year, but for some reason, they always catch these big brands of sunscreens out for not meeting the SPF rating that is on the pack. And I'm sure that this has happened in the past, but for some reason this year it's really been picked up, and I think it's been picked up because it was such an iconic brand that was underreporting their SPF rating.
Lee: It was Ultraviolet, and Ultraviolet is just really popular. And I think the founder came out and really defended her SPF rating. And then it was found that it wasn't hitting the SPF rating. So, I think that’s why it got more media this year than it has in the past.
Irene: That Ultraviolet sunscreen had a base formulation that was used across a whole bunch of other sunscreen formulations in Australia, and what ended up happening is that everybody that used that base formulation came out of a WA manufacturer called Wild Child. What's really interesting about that is this Wild Child manufacturer was getting the sunscreens SPF tested overseas, which I actually didn't think was allowed. When I was making my sunscreen, I had to get it SPF tested in Australia through an Australian lab.
Lee: Do you know how they do it? They actually burn your skin. They put the sunscreen on and then burn it. They pay uni students like $10 an hour to do the testing. But anyway, they were doing this overseas, which feels dubious. I've tested US sunscreens in Australia before, like BB creams labeled SPF 30 or 25 on the pack. Even though BB creams don't need TGA approval, they still must meet packaging laws. Those came back as SPF 3 here.
Irene: I cannot believe that. Things like that happen in my industry too. They get TGA regulations in Australia, then take products to China and change everything. What other controversies are there?
Lee: There's more. Another article revealed an Australian sunscreen manufacturer making private-label versions, using the exact same formulation for about 50 different brands, not just a base, but the full formula. Sometimes even the same bottle shape, just a different sticker. They all shared the same TGA number, which I'm pretty sure isn't allowed. The TGA later clarified if that's okay, but imagine 50 brands selling identical products at different prices. That's why I'm not a fan of private label.
Irene: A couple of those brands approached me to stock them, but it didn't feel right since they were all the same. In that case, Magoo's founder tested them and told the media they claimed SPF 50 but didn’t meet it. That's the second controversy. The third and fourth involve chemicals. The TGA announced before Christmas they're reviewing limits on certain ones, untested for hormone disruption.
Lee: This week, a Courier-Mail and Herald Sun article cited Freedom of Information emails about another ingredient, banned in 20 countries, in Australian sunscreens (including kids'), untested for safety in pregnant women and children. The outcry is we weren't told. Sunscreens are being pulled for safety, contamination, or dodgy ingredients. How do we choose a legit one?
Irene: We must wear sunscreen. Slip, slop, slap; you know that better than anyone. Trust the SPF rating first. Those Choice-affected ones are pulled now, and brands have retested post-scandal, so we're more confident. On chemicals, even chemical sunscreens beat none, but for natural (zinc/titanium-based), they must match chemical SPF ratings and be TGA-listed. Check the TGA number on the pack for rigorous Australian testing.
Lee: Does the TGA system work for consumers, or is it tough on small natural brands? It absolutely works for consumers. I'm pro-TGA. I love natural sunscreens but wearing any beats burning. People skip sunscreen fearing toxins, so pick natural with TGA listing. Avoid small suppliers selling plain zinc oxide with shea butter claiming protection. No TGA means no guarantee.
Irene: One annoyance: TGA-listed products only need active ingredients listed (e.g., 22% zinc oxide), implying natural. Check the full list on the TGA website by entering the number. It often reveals 15+ inactive ones. That's my trick for stocking; Google "TGA [number]" for ingredients.
Lee: On the environment, do "reef-safe" sunscreens live up to it? Some chemical sunscreens destroy coral, so avoid them at the Great Barrier Reef. Natural zinc oxide ones call themselves reef-safe, but environmental groups question if zinc or titanium dioxide truly is. It’s less bad than chemicals, but the jury’s out. It's on labels, but not 100% verified.
Irene: What about SPF ratings like 10, 15, 30, 50? Back when I made sunscreen, natural zinc maxed at SPF 30. Now SPF 50s are common. SPF measures UVB blockage. SPF 50+ blocks 98%, SPF 30 blocks 97% (just 1% difference), SPF 15 blocks 93%.
Lee: Does that mean how long it lasts? Labels say reapply every 2 hours. That’s not marketing; sweat wears it off. Reapply often, especially swimming, plus hat and shade. Follow directions based on formulation.
Irene: That's so interesting. I loved having you as our first guest. Anytime, Lee.
[28:10] You’re On Speaker with Di
Irene: Welcome to the You're On Speaker episode, and Di, you're our first caller. Welcome! Thank you. It's a little bit exciting. I don't know that I've come first on a lot of things, but anyway, thanks for setting up this podcast and giving us an opportunity to ask some questions.
Lee: I've actually got a question around prebiotics and probiotics. I read a lot about it and hear a lot online, but I actually don't know what the difference is between the two, or the frequency that you should be having either of them. There's a lot of different messages online, so I was curious whether you could offer some insight on that. That's such a great question, fully over to me.
Irene: Hi, how are you doing? Yeah, good. Thanks. Thanks for answering the question. No problem. I do get this a lot in my nutrition clinic, actually, and it is really confusing. Gut health can be quite complicated, but really, at the end of the day, it's quite simple.
Lee: If you're interested in learning more about prebiotics and probiotics, I like to think of the gut as this beautiful ecosystem, and we call it the microbiome. Within it, you have trillions of different bacteria living all together in this one ecosystem. When you're really healthy, your microbiome is nice and balanced and everything's running smoothly.
Irene: But sometimes it can get out of balance. Some of the things that throw that off are smoking, antibiotics, a really high sugar diet, that kind of thing. So, we want to keep the good and the bad bacteria nice and balanced. The way that we do that is by eating more probiotic-rich foods.
Lee: When you think about probiotics, they're like the reinforcements that you bring in. There are good bacteria in foods that you can eat, things like yogurt, kefir, and sauerkraut. You've probably heard of all of those. They're basically the good bacteria or the seeds, and they are the ones that are really helpful for the good microbes in your gut ecosystem.
Irene: The good microbes in your microbiome have to be fed. They're like little babies with their mouths open. That's where prebiotics come in. They act as the fertilizer for your good bacteria. They are things like non-digestible plant fibres, inulin, chicory root, or resistant starch.
Lee: These go into your body and feed all the good bacteria, and the good bacteria love to munch on them. Foods like onions, garlic, and oats can really help fuel the bacteria that is already in your gut
