The Dr. Hyman Show · How Jeff Bland Reversed His Biological Age at 79 (Part 1) · 28 May 2025 podcast
3500 year old food. Can you imagine in the Fertile Crescent, there were really two, a major source of nutrients. The first kind of husband and crop was millet. And so millet is in the Indio regime considered a very, very important non-gluten grain. It's a cereal product that's not gluten containing.
In the Himalayan region of the world, in China, you had a similar 3,500-year-old product that was agriculturally husbanded that was this tartary buckwheat. Tartary stands for the tartan district of China, which is up against the Himalayans, northern China.
In fact, I just was in discussion this last week with a farmer of Tartary Buckwing in Bhutan. And he was saying how important that food has been in the Bhutanese culture and why they have very good health outcomes. And of course, it's a happy group of people too. So maybe there's lots of things going on there.
But he's been very concerned that they're converting the tartary buckwheat, which they call black buckwheat, over into other crops now because of the pressure of getting increased yields. And so people are losing the nutritional benefit in Bhutan. And he was very worried about maintaining their cultural heritage.
And we in the United States, actually, it's interesting, our colonial ancestors brought over Tartary buckwheat, because it was such a hardy crop, it didn't need irrigation, it didn't need fertilizer, and bugs don't like it because it has such a high level of these phytochemicals that it's almost like it's natural pesticide. Years ago, tartary buckwheat was lost in North America.
people stopped growing it and replaced it with uh seed and soy and wheat and soy corn and so it got lost in this country as well you know in in some of these countries they actually will will use it in many ways they make noodles so soba noodles is in japan but they also have in japan this
That's right.
Our immune system could be considered divided into two components. And that was the part of the immune system that produces antibodies. It gives rise to a a memory effect that we used for immunizing people, and that's our B cells. That's so-called the adaptive immune system.
Those cells adapt to the exposure to something and remember that so that the next time you're exposed, they will produce something that helps to detoxify it, an antibody.
And people have thought historically over decades about immune system is that's where the action really is, is in the adaptive immune system. But there's another part of the immune system that's the first level of the immune system, which is called the innate immune system.
And yet goes all the way back. Plants have an innate immune system. So this is definitely ancient. It's phylogenetically conserved. It goes through all different insects and into organisms of all types. And it has been said until recently, and when I say recently, I mean within the last 10 years, that this part of our immune system is kind of dumb. It doesn't... it can't learn anything.
Whatever you were given genetically for your innate immune system, that's what you got. And it's the first line of defense. And those cells basically just respond by engulfing foreigners and killing them by certain kinds of biological processes. And you just hope it's working well. because there's not much you can do about it if it's not.
Exactly.
foreign invaders the macrophage which is a member of those cell type in the innate immune system has these arms as it's a big floppy job of the hut type cell and it puts its arms around foreign stuff and then it squeezes it and then it releases chemical the klebanoff reaction which as you said are hydrogen peroxide and oxidants that kill it so it's chemical warfare it's like pac-man i think of macrophages like pac-man they just go around but you know gobbling up the bad stuff
But there's not much we supposedly can do about that. It's either going to work for us or not. Now, within the last 10 years, da-da, new discovery. The innate immune system can be taught, and it can learn, and it can be trained to be better.
Let's say why. Because it turns out, if you ask, where is the innate immune system concentrated? Where is it localized in the body in higher levels? It's in the mucosal surfaces. And the first place that our body sees foreigner is where you find most of your innate immune system, like the gut mucosa, the lung epithelia, in the nasal passages.
And so if your innate immune system is kind of not doing the job, then it slips through the innate immune system, whatever that is, And now it has access to the second line of defense. And you talked about this situation that we saw with regard to COVID-19, where people died in their own fluids because their immune system overreacted.
And they produced all this stuff trying to, well, that's because the innate immune system never had a chance to kind of do its work the first time. And the second set, the adaptive immune system, now got overwhelmed and it just went wild and went into the cytokine storms, what they called it, which was a consequence of
yikes, I'm under siege, I just have to throw all the tools against it, and that person actually ends up dying of their own immune system overreacting. The construct that we have an appropriate first line of defense, we teach that immune system, the innate immune system, to be vigilant and resilient.
It's a different kind of specificity. Because on the surface of your innate immune system, you have what are called toll-like receptors. And those toll-like receptors pick up information of specific types, like gut bacterial lipopolysaccharides, and then respond to that by defending you against that message. And
