Diet, Nutrition, and Cancer Survivorship | T. Colin Campbell, PhD (2007)

8:30 first speaker is minimizing prostate cancer through diet t : camel whose emeritus professor of nutritional science at Cornell University in Ithaca Arthur Campbell is the author of the China Study startling implications for diet weight loss and long-term health his principal scientific interest which begins with his graduate trainer late nineteen fifties has been on the effect of nutritional status a long-term health particularly on the causation of cancer thank you very much for that very kind introduction I want to thank dr. Mark Schultz and Jim O'Hara Amy Greene for inviting me to this very prestigious conference it's indeed a pleasure to talk to a conference like this medically oriented conference about this topic about nutrition I spent many many years more than 50 I guess now counting all together working in this field as many students and colleagues mostly at Cornell University doing this work and much of my work in the beginning and throughout my career I had to do with trying to understand really what cancer is all about all the way from the cellular level through the whole body level but along the way nutrition became very interesting and I learned a lot of things that I didn't expect to learn in fact my views these days are rather different than what they were when I was a student in fact quite dramatically different but in any case I want to get into the presentation it's hard to talk about a subject like this is complex as it is quite frankly and just the minutes we have so all I can do really is to kind of go through a hop skip and jump through some of these significant observations that in fact I and Mike my students work on over the years of my colleagues so let's start off then and and and first to mention this identity that the message I want to tell you is not specifically just for prostate cancer it's a message that has a much broader and diverse effect on cancers of all kinds diseases of all kinds I should say and so it's a generalized view but it's a view that actually applies I would I would argue to prostate cancer as well as other cancers to let me start here with this first to this first slide and show you the kind of model that we tended to work with in science to describe the various stages of cancer what you can see here going from the color coded green to the on the left to the red is sort of the cancer progression process cancer as you may know takes a long long time from the time for the first seeds on through the the to the development of the clinical diagnosis essentially and it's divided oftentimes into initiation for most in progression initiation really has to do with the genetic seeds if you will promotion has to do with the long period of time over years when in fact these early seeds these early cancer seeds are beginning to grow and coalesce and develop into what we call tumors and eventually we get diagnosed and of course then the things begin to change so but but it's a continuum I want to emphasize this idea that continuum and the research I'm going to describe that convinced me of a very different view it's largely concerned with the motion and during promotion during this time it takes years decades if you will whereas initiation in the contrast that's just the time it takes for let's say for us to get our genes impacted by a chemical or something like that that's occurred so all the time most of a lifetime to some extent sort of creating these infant cancer cells nutrition is this long period of time that's the period of time that I really want to talk about in sabores own research is concerned you know without getting into the details of why I got involved in this particular line of research I just want to show you some results these are results having to do with experimental animal and I learned early on actually when I was working in the Philippines sort of survey are coordinating a nationwide program of teen and malnourished children that protein it seemed played a role in cancer development and it was on that basis without getting into all the details was on that basis that I came home and we organized a rather major research project that continued for the next about thirty years funded mostly by the National Institutes of Health and also by the American can study that led to this series of results that I'm going to describe here and this one just touch on just a couple highlights like I show hundreds of slides to illustrate this point but I think these next two or three slides might do the trick basically the cancer that we were looking at in this particular case as a model to understand cancer was liver cancer in rats to be specific and so we were interested in the effect of protein on the development of this cancer over the development of cancer this slide here basically shows that over the early stages of that development first twelve weeks if we fed diets that contains the good levels of protein the recommended levels of protein which incidentally is 20% of total calories as opposed to feet in diet five percent which is considered not to be enough quite frankly there's enough when you get to the adults but in any case feeding the regular levels the good levels as you can see the cancers once formed started to grow over the first 12 weeks and quite a dramatic difference this coincided in fact with an observation was made by some Indian workers prior to that they really got me into this but then the next series of studies illustrated here in one slide really turned out to be quite provocative namely if we started feeding animal the first three weeks for example 20% proteins and glute levels that recommended levels we will and then squish them to five percent we turn to cancer off if we then returned and fed them the 20% protein diet turns it on so we get to a point in time when we could actually turn on and turn off development admittedly it was the early stages so beg some questions that whether or not this really applied to let's say for long-term earns but in any case this is the early stages first twelve weeks and it was the period during promotion now the promotion period as I say nested period as a return to that that's the period during which the the nutrition acting as a fertilizer if you will of growing these campuses that's the period of time that's really critical in this whole process but it turned out we were feeding twenty percent in five percent but I wanted to know something about what about intermediate levels going let's say from four percent up to twenty percent protein is an essential nutrient and I'm sure that you all appreciate that we need protein the question I'm really referring to here is what happens when we consume protein in excess of our needs and so this is illustrated here in these external animal studies namely up to ten percent protein that's about them out they need they don't actually even need that but they need about that at least or that that's plenty for them to do all the good things the protein does and it's when they start consuming diets an excess of ten percent we can see the mister starting to develop and that concept of the threshold is is common to nutrient action there's oftentimes nutrient thresholds the nutrients are good things they do good things for us but when you see the threshold we see the level that you know beyond that that's what we get it to mister and that threshold concept they say is is is very important in context what I'm going to tell you here now what I just quickly described was what happens in the early stages of cancer development here's a study where we followed cancer development during the entire lifetime of these animals a lifetime in case of rat is about two years about a hundred weeks and so what we did there we just did by present twenty percent we actually did more than that this is just as a sample of some of the data out of a very large study but we fed five percent or 20 percent diets for the entire one under weights and if you look over in the right-hand side you'll see the degree of cancer formation we call it tumor severity which takes in consideration the numbers of Timbers as well as the growth rate size of the tumors and you can see a huge difference a huge difference being the good lot of the protein really turned on that cancer big time and this coincided in fact what the early workers in India had done coincided with what I thought I saw on the children Philippines as well five percent not they're really interesting part of their study if you can see there and it's sort of the second column area on the left is that the 20% animals all died were all dead at the end of their lifetime of liver cancer these animals had been exposed to a carcinogen cause liver cancer but they're all dead the animals given to five percent allegedly not enough to support good health they're all alive and Trippi there are hair codes for sleep Doha phonetic aids or energetic all the rest and no cancer it was dramatic it was dramatic and we actually looked at this many different ways the protein we were using was casing casein is the main protein in cow's milk soy protein whey protein didn't do that even when it was fed at 20 percent of calories so there's a dramatic difference between casein and these plant-based proteins I found this to be provocative and that's an understatement because I'm rain I was raised on a dairy farm milking cows and we milked cows and we drank milk and I drank generous quantities of milk because in those days to the extent I even knew anything about nutrition it was largely because of the protein content in the cow's milk that we thought we are doing the right thing I actually went away to school then the Cornell University did my doctoral dissertation I'm trying to figure out how to go animal based protein Cal's protein if you will more effectively so it could consume more of it so that was the early part of my my career this was a shot and it took me a while to get over we had to get over move on it turns out the casein had this effect what was suggested here too was a case is an animal protein these others are plant proteins so I thought maybe was emerging here I dichotomy between what plant proteins do what animal force is to do without giving all the details of that I'm going to share with you my confidence in the idea yes there is a major distinction between animal protein rent pros in terms of what they can do and not just for cancer so let's stop here quickly for some main points namely a low protein dietary protein something like 5% also decreases both initiation and promotion for this infection for most of primer that's important is that that way because we knew or at least I thought I knew that in those days that during the promotion stage cancer is reversible necessarily basically demonstrated so the fact that that it operates during that period was interesting so the nutrient activity during promotion strongly indicates that cancer development can be controlled perhaps even reversed by nutritional means that's an exciting concept that's an exciting concept especially when you consider in the context of the levels of nutrients consumed in this case not for roi Bureau excessive unreal levels these are levels well within the range of which we all experience quite frankly so we look for how does this work in science we'd like to learn how it works and a lot of people tend to think is fundamental to Western nutrition fundamental to Western science we want to have something more so you want to know what they so called explanatory mechanism is because we know that then we can do things like maybe develop some drugs and this and that and sort of intercept that right reaction well this was again another very provocative idea it turns out there is no such thing as a single explanatory mechanism there's a whole bunch of stuff all working on hundreds of thousands maybe of reaction interacting it's a very complex system we started looking for mechanisms in fact during the initiation stage and during the promotion stage you can see there and every time we look for a mechanism we found one which you know that turns on a light bulb to you know because it's not an interesting connection so we can't stop this by stopping a single mechanism essentially it's a whole thing sort of operate together and that that principle held true for many other work much other work we did we didn't incidentally do just protein in this concept because once we got in got involved in this and I I started realizing - nutrition interest is really important wanted me to look at some other cancer systems - like pancreatic cancer and an ultimate initiative like carotenoids and fat and breast cancer mammary cancer and things like that and as we got into these kinds of studies we can see this dichotomy only getting reinforced this dichotomy of animal-based nutrients as opposed to plant-based nutrition animal-based nutrients went that way plant proteins based on that way and it was major it was a major distinction and so for cancer prevention a diet that has less fat less animal protein more plant protein more carotenoids essentially is the kind of diet that prevents cancer and reverses cancer if we can go that far to say that kind of thing and so let's return to this scheme that I showed you in the beginning and you can see there I've elaborated a little bit the promotion it shows it reversible that's clear it's reversible whatever stage plant-based plant-based foods push it to the left animal-based foods push you to the right again coming from why I remind you I'm coming from the farm we did their own slaughter of animals I did we know toward cows we did all the rest a dregs as this is trouble the question here in this slide is well okay if it's reversible during promotion what about doing in later stages when people already have cancer I wanted to speculate that it would operate there - and I'm convinced it does we just tend to ignore it much of the research is tend to ignore it or not even study at all but basically the same kind of conditions that operate during promotion prior to the actual diagnosis of the disease or the same kind of forces and mechanisms are operating after diagnosis to an ongoing a liminal button some of this kind of thing but I'm really convinced that's a very exciting area of future research and we have a lot of evidence now to support that point of view in any case so that's what it works how I should cancer and then wanted to raise some questions well what about some of these other diseases so actually I got involved about three or four years ago with my youngest son there's now school to write a book called the China study whereas we put this story together as I started to write this down and try to understand what in the world was that I thought I knew we wanted to go back and look and see if this was consistent with some of the other kinds of diseases to the troubled us and it turns out here's a list of a bunch of diseases not a complete list for which there is published peer-reviewed research really substantial stuff that goes back a long time much of which has been ignored by the medical community I must tell you and by my research my own research community but in any case the same plant-based diet comprised of whole foods is known to prevent to suspend and/or cure all of these diseases some of which are very serious as you know some of which are perhaps just problematic and troublesome but in any case that's quite a list and I can spend here hours talking about some of the research has been done it turns out that this idea of consuming plant-based diets to prevent cancer reverse cancer is the same kind of diet that actually restores health and prevents diseases of all kinds it's just it's the depths of very definition almost of Health at the same times also promotes superior physical fitness believe it or not I've been working with some world-class athletes who have gotten into this and a finding in fact they're the ones that tend to get up in front of the others when they do it the right way as far as performance is concerned it's very very exciting area I think athletes have unfortunately elite athletes and have gone too far into the high protein high fat low fiber kind of diet to do their various and sundry things and they need not do so okay so I'm talking about something that's whole ism I call it holism yet word in a dictionary usually spelled hol is I don't like it spelled that way that's my spelling because I like to talk about the whole so what we've summarized in lies three sides is that there are countless dietary and lifestyle factors I really mean countless I don't know how many hundreds of thousands of things and foods that might be operating in a sort of system who operate then between you know through countless biologic mechanisms again unlimited really to produce countless health and disease inputs the same thing it's a common formulas a common message especially this operating in this way and it's the we have to acknowledge the fact is very complex as far as a biochemistry concern and it's a mistake to focus a one just one little bit of it at a time not being aware of the whole but the whole is much greater than the sum of its parts it is indeed and present in fact the converse of that as reductionism as I call it which is fundamental to the way we do research is fundamental to the way we have actually practiced our medicine I call it when it's called naked reductionism in other look at things in isolation single chemicals doing single things by single mechanisms is trouble we're asking for trouble going to do it that way especially when you consider the question dynamic and that's where a lot of confusion arises in the public about nutrition people tend to want to think what does this nutrient do what does that one do and how does it work that's not the way nutrition works we've got to consider it you know in a context of Whole Foods so I say if there's an evil force in bottling research it is in fact make a reduction in them I'm working on a second book right now there's sort of elaborate to this point but I I think is a very important point because it's fundamental it's a way we in a profession think wrongly as well as the way the public thinks wrongly about what really creates health now I'm going to show you just with the consequences of that wrongful thinking I'm going to go back and just choose an example that you may have heard about this is a comparison for example that was published in the 1970s by my good friend my late friend Ken Carroll and some others are showing a relationship between total fat intake and breast cancer similarly it was shown for colon cancer heart disease if you compare different countries you can see a really impressive relationship the higher the fat intake you higher the breast cancer rates that slide this thing was shown probably more nail to slightly medicine almost for many years that this particular observation here is what the idea for the public to think about cutting down fat intake and specifically cutting down the century flatter date that was a not a good message a good idea to cut down pat yes but that wasn't the end of the story there's far more to it than that show this nice relation look like there's something more here so I went back and actually took Ken's data and looked that a little more carefully turns out if you draw a line if you look at that sort of in a theoretical sense it shows this suggests that at least is a threshold and this constant threshold again is important in other words you can consume up to a certain amount of fat in a diet and in theory not expect to get breast cancer I say in theory and of course we know we need some fat and or that no question about it the fat just normally plus present let's say in plant-based foods so that's that's the relationship that was shown there but then Ken had some data too that wasn't didn't get much attention you can look at the relationship between plant fat and take a breast cancer signal relationship you look at animal fat and taking the relationship returns and here the threshold is zero in other words it's sort of suggestion if we look at it from the theoretical point of view it sort of says putting any fat animal fat or any fat from animal foods that diet is going to tend to increase breast cancer risk so we see this dichotomy emergency and plant fat versus animal fat this wasn't this part of the story wasn't told as far as says dateable concern but it turns out that it's not just that they can be animal protein because the correlation between total fat and animal protein is almost perfect 94 percent you can see there and so we can say okay that's the animal protein intake we ought not to consume an animal protein because in theory you know the breast cancer rates colon cancer rates heart disease rates and other kinds of diseases that go together can start to increase so it's not just protein also by the way it's animal food it's animal - so that original chart that was shown really should have been animal food so we have evidence showing that dietary fat Allah is not the cause of breast cancer this is what I'm just elaborating here this particular example lots of other evidence too for the same point of view but I wanted to show this because this is what had been commonly discussed over the years we so one kind of evidence of what I just showed Association of animal protein and total fat and Ken Carroll's international study in other words it can be animal protein as well as animal fat and I would argue in fact it's probably much more significant there's another example again a popular one that many of you have heard about I think most of you know about the Nurses Health Study I'm a nursing Health Study you've heard of that and it said Duncan the study done Harvard now costing something like a hundred and fifty million dollars on a group of about 90 thousand a hundred thousand nurses or so there's evidence in that study too although the investigators not particular what admitted to quite this way but there's strong evidence in the air to to illustrate the same point I'm going to make as a point that led to a lot of confusion that's why I'm showing you this because it has to do with this naked reductionism concept here is a relationship as the Nurses Health Study Group investigators here's a relationship between fat intake and breast cancer after eight years actually now after 14 years you can see those dotted lines across there you go from let's say something pretty high fat guys like 49% accounts that's a pretty fatty diet down to something less than 30% 29% or so and as people as women decrease their fat intake from around 15% to 25% or something like that breast cancer doesn't go down and here's here's what here's what people did they took the Ken Carol study or the scientists did this and told the public about it they started taking out fat of the diet and how did they do it they started using low-fat milk they start using skim milk they started using well lean cuts of meat and things like that in the hope that by decreasing that alone they would decrease breast cancer risk doesn't work it doesn't work and it won't work for heart disease either and this is basically what was shown here because that's what these women were doing they didn't change their ratio what they did not do they didn't change the ratio of the animal to play based food so they didn't do in fact these these women in these nurses in this particular study were virtual carnivals they consumed and that's what they were told to do or that's what they led to believe that's what we did that's what I did you know because even by using lean cut skim milk they're jumping from the frying pan into the fire because they're taking out the fat and the protein content actually goes up so in this particular study here for example the lower the pattern take a higher the protein intake and the protein intake was already high in the beginning eighty one percent of the total protein in these women eighty one percent was from animal-based foods large from dairy so now we're getting evidence you can guess that dairy is related breast cancer strongly related to breast cancer just this is one thing so that we did that so that study moved along I'm quite critical of that kind of study because all the women in our study were doing everything wrong and they change their fat intake yell but that didn't make a whole lot of difference as you could see but there are other studies unfortunately many of the human studies that we have done over the years basically we use a cohort of people who are consuming dies in the wrong way we don't read that we don't have anybody in the study who really should be doing things the right way so how can we learn we get a lot of confusion results the public gets confusing all the rest of it the Women's Health Initiative feasibility study that's a big one that had three arms to that study about forty hospitals in the country are involved many of you may have heard of it there's something similar to the nurses so send exactly but it's similar and so they were also focused on if you get the fat out of the diet you're going to get some good things out of this they spent more than billion dollars now so far during that study and the results of the same thing and so when the results came out that fat has no relationship in breast cancer featured in the front page of the New York Times headlines everybody gets confused oh my gosh a steak you know that's not in other words the whole dietary hypothesis begins to fall apart because of this mischief of this wrong conclusion it's really about whole food is not about fat and so I just wanted to show that's what happens when you think when we use naked reductionism doing research and then tell the public about it and there's lots and lots of other examples there's a beta carotene trials in other words foods that are high in beta carotene vegetables and so forth and so on are associated lower cancer risk right so what it resources do they pull that to beta-carotene put a little pill and gave it to some people and see what will do and what did it do it in cues to increase cancer risk didn't decrease it nutrient supplements don't work not the long-term they simply don't work that's naked reductionism chemical carcinogen testing is another fantastic example we tend to conclude the single chemicals cause cancer and we forget we just forget about all this second stage of promotion sort of controlling whether that occurs it any help this is something very fundamental really has to do with Western medicine the fact that we tend to rely on single chemicals usually drugs to try to achieve something good in the long term and then a test what we tend to do is patch over things I think at least compared to diet diet is far more significant let's get to the China study quickly eventually I had an opportunity with colleagues from China and colleagues from University of Oxford and elsewhere to organize the study in China to go there in the early 1980s right after our two countries started to talk to each other to go there to see why it was in China the cancer was so common in some counties and not in others this is a Atlas here for breast cancer you can without seeing all the detail in that the breast cancer is much lower than China overall in here but actually nonetheless there were differences between high rate regions and low rate regions so we wanted to go there and I wanted to put into play this idea of measuring a whole lot of different things to see look at patterns and see in fact you know what might come out of that kind of studies so we had about four dozen different kinds of diseases to consider we collected all kinds of information you can see there it was very elaborate study to be honest about it we ended up with 367 items of information of variables we call them about four dozen different kinds of we measure things in the blood in the urine and food analyzing about two dozen different laboratories around the world got involved in working with us on this and so we had this chance to get into the data and ended up with a huge volume of data that we can begin to look for patterns and we started our started looking at little details of that big pattern of stuff and here's some here this has all been published breast cancer versus fat estrogen versus breast cancer a genetic breath I mean on and on and on what came out of these detailed analyses of the bits parts was they see the same thing the closer we get to a plant-based diet Whole Foods plant-based diet not the nutrient supplements whole food plant-based diet is closer we get to that the greater is going to be the health outcome and the less is going to become the disease and I should say a low-fat community let me go to the next thing here here here's one might be looked at the China data this huge volume of data when we look at data this way we have to use different proteins we can't look at single little details so all here's a bunch of diseases that we had data on in China and I just simply wanted to see if in fact there was any aggregation of similar kinds of disease in the same area and you can see two lists here so-called poverty diseases and also affluent diseases all the diseases in any one list is correlated with diseases in its own list and inversely correlated disease in the Arbutus so in other words the disease is on the right or diseases that tend to get us in washing countries industrialized countries the disease on the Left had to get poor countries so this suggests is comes in common maybe some common causes I wanted to know what were the common causes let's say of affluent diseases and we measured a bunch of stuff and it turns out that as cholesterol goes up in the blood these diseases start to appear and this was really interesting because cholesterol in China in rural China the ranger cholesterol goes from 90 to 170 the average is 127 they're high as near our low and are consuming mostly plant-based diets so as these people increase our causal levels they increase as they start putting an even small amounts of animal I found that surprising because I didn't think we see that as soon as small amounts of animal food start to be put into the diets of these as they get more money and they can buy us a side of beef or whatever as they start consuming more and more of this animal food their cholesterol is our levels start to go up in that and turn associated with all these Western diseases just an indicator crucial is not to cause it's an indicator so if a bunch of stuff starts going wrong at the same time and here's just basically the total cholesterol and a bad cholesterol HDL you can see the correlation for those of you who are interested you see the highly significant associations and we'll protein is associated with increasing levels of total cholesterol and bad cholesterol and plant protein as an indication of plant-based foods of course is inversely correlated so in other words it sort of affirms essentially what we were doing both in laboratory and other human studies so here's the big grand sort of conclusion away for minimal disease risk lesson from the China state virtually all of the observed associations favor the Nutri composition of a Whole Foods plant-based diet as they say what made this particularly intriguing in China if we go back and take those data that Ken Carol had in the beginning looking at breast cancer for different countries of the world and I marked it off here Wester studies are all done at the top right quadrant we're all consuming the wrong stuff we do studies and we get confused and we tell it to the public and the public gets confused and you we change little things here and there just trivial changes aren't going to make much difference but then in the lower left-hand quadrant no studies have been done down there that's where the China Study was and what we basically showed is that we start learning in reasonably small amounts of animal-based foods and I should add not at that time as we start consuming processed foods to numbers getting away from whole plant foods we get that problem so there's the main idea plant-based diets enhance health print and cure broad range of the diseases it works throughout the disease process as a electric I suggest again isn't it diet I'm talking about whole vegetables fruits grains legumes nuts little no added salt sugar fat those foods that's what we need to work toward and the results can be amazing incidentally this is a high carbohydrate diet you can see eighty percent is a high carb diet you may find that surprising carbohydrate basically only comes from plant foods when you can see them plain foods that's a high program unfortunately there are some really mischievous authors and been out there was no training in nutrition writing books talking about high protein low carb diets they were the ones that invented that silly term carb I'd like to think of carbohydrates but in any case they confuse the public about talking about low carb diets when you're really talking about refined sugars white flour things like this there are not that kind of carbohydrates not what I'm talking about I'm talking about Whole Foods which incidentally is a high carbohydrate kind of food so this is my final slide in my research carrier what as I look back I the thing that that intrigues me most and convinces me most about this message is to try to work out some principles principles that can apply across genders male and female principles that apply going from one species to another principles that apply from early stages of these diseases to the late stage of disease principles that apply going let's say from good really good health to ill health principles so I think principles once we get their principles in our minds we begin to understand what's going on that's what's so impressive and here are some principles health health and diseases the continuum is not a dichotomy we don't for example in cancer all of a sudden we're free of cancer and suddenly we go to the doctor and duck says you've got cancer no no no it just been noticed at that time that's basically what it is because there's a continuum so the factors working toward that point also work after that point multiplicity mechanisms works like a symphony or body is a symphony when you think of a nutritional sense it's beautiful those are responsible thresholds are very helpful to understand what they are we can control our genes through nutrition so what are we doing all this research and getting so concerned about genetic disorders plant-based diets keep all these mystical genes that we have in our system under control the effect is comprehensive it applies across the board and then since then I should tell you I think this is a validation of history I've really been quite interested in the history of philosophy in the history of science this idea was extent and popular in the 16 and 1700s by the leading authorities of the day it also was prominent in the 1800's by serious people too and it got put to sleep about the late 1800s as we got into the Industrial Age for all sorts of different reasons so and it has it really does have a very old history and it's been summarized as I said before I sit down with my son who is actually a graduate in theatre from Cornell University was an aspiring actor in Chicago and good writer I I said he could write better than I could got him involved come back and he got so carried away with this thing who he decided to change his career from theater and now he's in medical school anyhow it's in that book if you want to see you know how I came up with these weird ideas different ideas of what I ever thought over starred in but I have to tell you I am enthusiastic what this can do and since this book came out the feedback we're getting at the present time it is really gratifying the number of people who are trying this and writing and telling you could see one if you want to look and see look on Amazon they write reviews on there just look at the reviews that have been set in it's really pretty pretty incredible what this kind of approach can do you know to actually create health and prevent disease thank you very much you
