Chapter 1: What is the Amazonian secret to brain health?
If you've heard me speak recently, you probably know how much I love Himalayan Tartary Buckwheat, a gluten-free seed loaded with longevity-promoting nutrients. My good friends at Big Bold Health have been carefully growing and researching this ancient plant for years.
After tons of positive feedback from me and their thousands of customers, they've produced the world's first 100% organic Himalayan Tartary Buckwheat sprouted powder that's easier to digest, richer in vitamins and minerals, and contains up to 10 times more plant nutrients like rutin and quercetin.
I love this as a topper in my yogurt, a sprinkle on savory meals, or an easy add to my smoothies and protein shakes. The sprout powder has no fillers, additives, or sugars and is farmed, sprouted, and packaged in the USA. Right now, Big Bold Health is offering my listeners a special offer of 30% off this amazing product. You can try it now by heading to bigboldhealth.com and use code DRMARK30.
Again, that's big-bold-health.com. At 65, I'm still pushing my limits, cycling long distances, trekking through Patagonia, and living life to the fullest. But staying active as I age isn't just about willpower. It's about giving my body the vital support it deserves. See, as we get older, our mitochondria, the powerhouse of our cells, naturally begin to slow down, stealing our energy and strength.

MitoPure is backed by solid research, showing it can boost cellular energy, increase muscle strength, and support overall healthy aging. Personally, I take MitoPure every day.

Chapter 2: How do plant compounds activate detox systems?
I've written about it in my book on longevity because it's such an interesting concept that these stress molecules in plants, and the more stressed a plant is, the more it makes up these defense molecules. Precisely. The more it activates our body's own embedded longevity repair pathways.
And you've got to have... the ones that are bioavailable. Like the most bioavailable one that we know is sulforaphane, which comes from broccoli sprouts, five-day-old broccoli sprouts. You've got to chew them well. Imagine you're a rabbit trying to eat a broccoli, and then there are these toxins being produced, which is the defense mechanism that all plants have, that for us becomes medicine.
At the right dose. And that will switch on these very same systems because the body thinks that suddenly you're consuming a poison. And it'll mount a huge antioxidant defense. It'll start producing glutathione, which shuts down normally at about the age of 35. It'll begin producing superoxide dismutase. A massive production of these.
But if you keep eating those broccoli sprouts every day, it'll shut them down. Say, hey, this is not poisonous.
Right, because your cells upregulate and downregulate in response to the environmental cues. That's why you get... alcohol tolerance or opioid tolerance, you need more and more to have the same benefit, right?
Precisely. And this is what the Amazon indigenous people discovered without knowing what an RF2 stands for. They just know that these were the sacred plants that promoted longevity.
But there weren't any broccoli sprouts in the Amazon.
No, they have a bunch of other, uña de gato, cat's claw. There's 50 others that are extraordinary, but we can't get them in the West because we don't know the quality that we're getting and we don't know how accurate the dosing really is. It's all in the dosing. There's other ones like curcumin.
Curcumin is an amazing one, but curcumin is 5% bioavailable, whereas sulforaphane from five-day-old broccoli sprouts that you grow at home, you've got to turn your kitchen into your laboratory. Right. We're all going to be hippies and grow sprouts in our kitchen now? Totally. We used to do that in college. Five-day-old broccoli, homegrown broccoli sprouts are 85% bioavailable.

Chapter 3: Why is gut health crucial for brain regeneration?
So Saccharomyces boulardii, and this is in my website, you've got instructions, it's in my books, is actually a yeast that competes with candida, brings balance to the gut, especially to this kind of dark area, this kind of black hole that we have in our guts of the anaerobes, the non-oxygen breathers.
And it brings balance to them and allows them to proliferate and it gets rid of the bad parasites. It gets rid of the H. pylori, for example. There's a really good science behind the use of sarcomycin. And it's been used with babies and children for 50 years to stop diarrhea.
Yeah, it's quite incredible. In fact, they use it clinically in medicine for people who have C. diff as a treatment. Precisely. C. diff, which is a clostridium bacteria that can kill you. I had it. It almost killed me. And yeah, it's a power-powerful compound. We call it a yeast against yeast.
And the beauty of boulardii, a saccharomyces boulardii, is that it doesn't stay in your gut. It doesn't colonize. It leaves after about six, seven days.
You know, one of the things we see a lot on our stool tests when we do stool analysis is a reduction in something called IgA. That's an antibody, the first line of defense of your immune system. Right. And when you say of COVID antibodies, those are the defense against COVID, right? So you have a system in your gut which interacts with the outside world.
And typically, with our guts being such a mess, we see a lot of people with suppressed IgA levels. And the Saccharomyces helps to bring it up. So you're talking about these sort of ancient organisms that we've symbiotically evolved with to help regulate our biology. and restart and renew processes that have been going on for hundreds of thousands of years, but we kind of messed them up.
You know, if you want to see animals in Africa, you go to where the food is. That's where the animals go. And that's what these bacteria did in our gut also. They went to where the food is. So they get to eat first. That's true. They eat first. They eat first. And then there's actually about 10 levels, 10 layers of probiotics in your gut.
And then we get to eat less because one layer, they begin to break down our foods. So, boulardii is an excellent remedy, and then you've got to feed the others. And what do they feed on? They feed on the stuff that you don't digest.
Yeah, one of the most interesting things I discovered in the last years, especially when I got sick with ulcerative colitis after C. diff, was this whole body of research, not just about fiber, not just about prebiotics and probiotics, but about polyphenols, which are the phytochemicals that you're talking about from these sacred plants that actually feed the good bacteria too.
