[Rhonda]: But you did a clinical trial, so are you involved in this clinical trial that
you kind of mentioned, like, briefly, which I thought was very interesting?
The actual one with fasting, where the cancer patients fasted either before or after the
chemo treatment, and I thought it was very interesting that you found, maybe you can
talk about it, but you found that their normal cells were more resistant to the stresses
of chemo, whereas the cancer cells were more sensitized to that.
[Valter]: Right, right.
So, of course, all of these starts in mice.
And in mice, we were able to show very strong effects, what we call differential stress
resistance, which is you protect the normal cells, but not the cancer cells.
And then, something called differential stress sensitization, where you kill the cancer cells,
but not the normal cells.
[Rhonda]: Can you explain that a little bit, like why that is?
[Valter]: Yeah.
Well, that is, again, because almost every organism, you can start with E. coli, actually,
bacteria, and then move to simple organism like yeast, and all the way up to mice, they
have starvation responses, right?
So, if you starve any system, virtually any system, they'll go into this shielding mode,
protected mode, and then, they sit there until food comes around again.
So, in this protective mode, they're very resistant to all kinds of things.
They're resistant probably because they have to be resistant to the sun, and to chemical
produced by other microorganisms that might be surrounding them.
And so, then, they happen to also, at least in mice and now we think humans, chemotherapy
is also one of the toxins that they're resistant to.
So, you starve the normal cells going to the protected mode when you starve a cancer cell
though because the oncogenes are the regulatory genes of this protection.
The cancer cells, by definition, can never respond, right?
So, they just, normal cells respond no matter what normal cell is, from a muscle cell to
hepatocytes, to a brain cell, but the cancer cells don't respond.
And that's really what's called differential stress resistance.
In the differential stress sensitization, instead, it really has to do with something
that, I think, was under-appreciated, which is a cancer cell is viewed as a smart cell.
In fact, the cancer cell is a very dumb cell.
And why is it dumb?
Because it is involved in all this high nourishment environment, right?
So, it's involved with a lot of proteins, a lot of amino acids, a lot of sugars, a lot
of growth factors, all these things are around all the time.
So, by making them available I know the oncologist means well, right?
But by making all this available during chemotherapy, you really helping one thing more than anything
else, is the cancer, right?
[Rhonda]: What you're referring to is them telling people to eat a lot of calories.
[Valter]: Yeah, of course, yes, so they tell them to eat.
And so, you know, because the cancer loves sugar, and loves amino acids, right, and depends
on sugar and amino acid, the more you give it, the happier it is.
And also these nutrients basically, make the normal cells sensitive, right?
So, you're making the normal cell sensitive, and you're making the cancer happy, right?
Instead of the opposite, which is making the normal cells protected, and make the cancer
cells miserable.
Why are the cancer cells miserable?
Well, because, again, having evolved in this abundance, once you take the abundance away,
it's like almost saying imagine somebody that had a very low IQ, you know, been looking
for food, you know, and if you make it available, it's easy.
Let's say, thinking about a monkey, let's say a monkey that has got a very low IQ, and,
you know, you put it in front of food all around it, and it's gonna have no problem,
right?
As soon as you take the same monkey with a very low IQ, and you make it extremely difficult
to find the food, now that monkey is gonna have a problem.
And, you know, and that's how we see the cancer cells.
You know, once the amino acids are low, the growth factors and the sugar are low, the
cancer is gonna starve.
And then, if on top of that, you hit it with chemotherapy, it just has a very low chance
of escaping.
This is why, in mice, we see cancer-free survival, meaning myself free of cancer only when we
combine the starvation or the fasting-mimicking diets with the chemotherapy.
We almost never see it when we use each one alone, right?
[Rhonda]: Mm-hmm.
[Valter]: We, and many other labs have tried that.
You see, which is great, often the fasting, the first thing we can say it's as good as
chemo, but you never see, you know, alone, each intervention alone being curative.
So, it's very interesting, and this is also very important to point out because a lot
of people, tend to either be in the camp of traditional medicine, or in the camp of alternative
medicine.
And people don't understand that, you know, that both of them are very important, and
when you combine it, particularly the alternative integrative medicine that's got a deep scientific
foundation, when you combine it, now you have a very powerful system, you know, in your
hands.
And, you know, whereas each alone doesn't work very well.
