Towards the beginning of Dr T. Colin Campbell’s
career he was working on a PhD in biomedical research by researching ways to improve the
supply of high quality protein by growing cows and sheep more efficiently. Later on He was then hired by MIT and went
on to coordinate a research project in the Philippines looking at aflatoxin a carcinogen
and liver cancer. He initially went with the aim of trying to
raise the people’s intake of protein however through a series of events Dr Campbell was
eventually made aware of a study done in India that had fed rats equal amounts of aflatoxin,
one group was then fed a diet containing 20 percent protein, while the other group was
fed a diet of 5 percent protein. By the end of the test, every single rat in
the 20 percent group had liver cancer or its pre-cursor lesions. None of the rats eating the 5 percent protein
diet had developed liver cancer! Dr Campbell then repeated these experiments. What he and his team found out, turned everything
he had believed about protein, on it’s head. Dr. Campbell’s group used the protein casein
found in cow’s milk but they went a step further and also soy and wheat protein Next
they replicated all the 5 percent-20 percent tests with all these types of protein
What resulted was to shock them all! The rats being fed the animal protein casein
diets in the 10-20 percent ranges all developed liver cancer or the beginning stages of increased
foci development. However none of the rats in the 10-20 percent plant based protein diet groups developed
increased foci production or tumors, even when given increased aflatoxin doses! You see the thing is when we’re exposed
to a carcinogen our DNA is damaged however this can be naturally repaired by our immune
system, but if our cells multiply BEFORE the damaged DNA is repaired then it becomes a cancerous cell. That is the initiation process of cancer. Anybody who’s been exposed to a carcinogen
has cells that have gone through this primary initiation process but it’s the promotion
process that decides how many cancerous cells form detectable tumors. For cancer cells to grow they need something
called promoters. What’s so cool is the promotion stage is
completely reversible! So what do high animal protein diets have
to do with the promotion of cancer well let’s hear as Dr T Colin Campbell explains more. The audio isn’t great so there are subtitles
available…… What we did of course is we could turn on
cancer by feeding them [the rats] more casein which is the main protein in cow’s milk. We didn’t see that with soy protein or wheat
protein and that was consistent with some other ideas about animal protein in general. I repeated what some workers in India had
done years before, it was very dramatic effect, so then I wanted to know, I’m still being
a sceptic, you know, for a little while because it was so striking. I wanted to know, how does this work at the
biochemical level? We always want to know, what is the mechanism? So we worked, I had a lot of students, you
know graduate students especially working on this question. One mechanism, one way we measured more or
less the extent to which the carcinogen gets into the cell. We found out that the high protein diet affects
that. After the carcinogen gets into the cell, these
chemicals if you will they are metabolised into products that are even more reactive,
then they themselves are and those reactive metabolites in turn are so reactive they bind
to DNA and if that’s not repaired and there’s way the body repairs them, if they’re not
repaired and then the cell divides at the time they’re damaged, that incorporates
the damage and subsequent cell degeneration which is mutation, that’s the way cancer
starts. So we looked at things like this enzyme that’s
activated by the carcinogen, does protein turn that on? Yes it does, it does it two different ways,
it’s amazing, its a very complicated enzyme. And then our mechanism we normally have to
keep all that stuff under control you know like repairing the damage to DNA for example
or cleaning out the cells that might have become cancerous we have mechanisms to do
that. The higher protein diet actually compromises
those mechanisms
