This Land Is Your Land; Dr. Teply

isn't is the continuing analysis and discussion others and hear what today's program is your host dr joe welcome to this land is your land our guest today is dr lester jay tapley senior nutritionist for unicef we're going to explore the problems of nutrition and food supply both here in the united states and on a world basis good to have you with us the template thank you very glad to have the opportunity to discuss this very important and in many ways very complex subject local be getting into the complexities in some detail and i think we can avoid it let's talk first about what

nutrition actually as perhaps we can define it in terms of the requirements for a normal child and for normal adult that's a very interesting way to start his matter fact nutrition is served somewhat difficult to define in fact of my titles a senior nutritionist is not really very different from you know that the third so it's really difficult to specify at which point one becomes professionally a nutritionist follow attempts have been made to make such definition but in a sense every one must be a nutritionist of a sort to care for himself and for his family but then with the specialized training in the basic science is related to food and nutrition at a certain point can claim to be a professional nutritionist their of course their various degrees of this training and various levels

of the preferred in his protector profession actually nutrition involves the provision of an adequate amount of the nutrients that are needed in the diet but there are many things and related with this including the social situation the family the year as sanitation cetera and a nutrition includes not only the year taking of these nutrients in the dead but their proper they gesture and so on their function in the body and all of those served in the broad sense comes under nutrition can we talk about what some of the actual food requirements are in terms of nutrition this is where in which sure we can be fairly clear we know that there are some four dozen specific name francis includes the major

components of the diet in terms of volumes which is the energy providing provide rates and that's a particularly and oh this means calories basic requirement and protein is another very basic care plan in the diet but in addition we have my name so called microbe and koreans and this would include vitamins minerals including the trace minerals record and quiet minute amounts but all very sensual the tonys in the day you cannot continue to live there will use a natural my current interest you mean that we require them only in very small quantities that's correct i mean in terms of milligrams or micrograms which is michael graham a millionth of a gram they're being four hundred and fifty four grams in a pound to give you some idea

what is involved or not mentioned the specific specific nutrients are required and then one comes to the quantitative side and there again we have their affair knowledge of the the amounts these various nutrients that must be provided to maintain their health and for syria group to provide for growth in the early years of life can we be a little bit specific about that yes we'll roughly how many calories or for energy must be taken each day and therefore young childless maybe something on the order of a thousand calories per day moving on upwards an unknown for urban average adult was not get too active physically perhaps eighteen hundred two

thousand calories would be sufficient now i think we're almost half today get into quantitative aspect of how many calories various foods provide and it was a rough places we can say that a surreal foods herbal agrees sugar insulin and also approaching if they were used for energy for colors program and france for a little more than twice that so i mentioned two thousand calories per day to give some idea basic limitless today how far you could cut down the volume of food must provide what's in space traveler situation might be if one takes effect well at stake there that he was a part of water which is moving to the metric system was for about four and fifty four grams

so if my calculations are right i think about day a half pound of butter which is more states that when they're provided roughly the two thousand coders so renee of course is no one would advocate eating only facts are you a mixed diet and therefore the volume is somewhat greater and i'm almost taken a certain amount of water reached as well so are there you are there would be a little bit specific about the uses to which the body puts these various interest loans they're so that mentioned her requirements for energy inc and this includes the basic requirements for just two staying alive making and maintaining a body function the temperature of the body all the work has to be done and i just run and building of tissues replacing tissues and so on for the year growing child there's an extra per month for him for the growth poses no

there's one word becomes more active or turns along there's a definite increase the requirements for for the rv no protein as a rather proper subject these days and that is a very important part of the diet and that it really caught the the tension of nutritionists is for a global nutrition is concerned about twenty years ago when the course your core a disease so very common in developing countries was shown to be year primarily due today a deficiency of protein usually combined with a low intake of calories but not always and very often were combined with deficiencies in biden's in minerals but dear the proteins required to provide

certain building blocks which we call amino acids that the body cannot make this is a different requirements businesses and italian that's correct calories or provide energy their tabloids change chemically oxidized song too to provide the energy the amino acids are used to primarily two were buildup tissues replace tissues to make clear specialized products that the body needs such as hormones and that certify and proteins of the main building blocks of the amino acids that well the main lessons surge which are contained and proteins and proteins being nothing more than their own chains are combinations of these various communal essence that's a providing these building blocks the annoyances which are taken up in the body and rebuilt

and to various tissues are hormones as alternately party supply the meanest that is correct yes what are the effects of the lack of these years nutrition and screaming is what you would imagine the serious very serious condition requests yorker probably most of the listeners have seen pictures of her as very unfortunate children that her develop the bloated bellies and so on and let's stick legs and arms and a girl thing and the dean our water logging of the tissues in the extreme cases and die without very earlier quick and special treatment many of these cases are doomed to death what is there about the lack of amino acids and proteins that causes question record for example well i have a good deal is known about

what what happens to various the posters is that go on in the body in eustace of the versions of our in a sense one could say that the whole mechanism is disrupted and alison rosen who were posters of digestion and absorption of nutrients building up issues are for example or four mei at the taking sufficient vitamin a and it is simultaneously with insufficient protean without that proteins blood at the bottom and they will not be utilized properly dollars you could live on vitamin pills alone that's certainly correct what are some of the other principle characteristics of malnutrition well there are many forms of course and we've been speaking really generally of course your car for example in general is that one can

point to other specific clear signs of extreme deficiencies of the trigger new trend for example iron deficiency will will shorten their war hemoglobin the blood and day below a certain level this this is a very very serious matter that can any of these efficiencies can ultimately lead to death if not corrected so imagine biden aide is a very specific effect of vitamin a deficiency there which are seen in the eyes and there is a breakdown in the year tissue structure in the eye and which can be seen and eventually this will result in infections and blindness now in world war two this was seen in nine some of the year in european countries such as denmark or concern or one version of send we're more germs which were not fortified with that and they replaced boehner which had been the furnishings and they use

and it unfortunately this this particular condition still exists in many of the developing countries in tens of thousands of children in these countries go blind each year were group and trying to do something about this something has been done but to hear is an example of the situation for which we have the use of knowledge the we have the technology we not a fortified foods says it's a matter of delivery or delivery of the supplement or educating families to include certain food items into that not until it's an interesting interesting point that you've mentioned certain requirements for vitamins protein calories and so on how these requirements compare with our presence applause of the specific nutritional elements actually there's a fairly good basis for believing that that if the world's food

supplies global picture were evenly distributed in the city have increased and i might say even in most countries if the food supplies available were evenly divided our way most of the nutritional needs would be met well we only have a matter of distribution and this is a scene in the distribution in various parts of the country within families and those parts various parts of countries so they're certainly older members of the family may get to more of them are sure the young child make it coalesce and says one major problems so we have the you know distributions when letterman and also there's a tremendous amount of the losses of food waste

india's spoilage closest person so on so we're thinking we must to greatly increasing food production in addition to whatever we might do and correcting now this region and preventing much of this waste last mission they would get into a specific case i want to try if possible to find the dynamics of insufficient food available in a country such as india this is a problem that the country doesn't produce enough weight of food each year to feed its population is it too poor to buy the food on the world market or is it too poorly organized to distribute food to its people it seems that any of these three things are possibilities that all three operating forcibly year and it has made great strides in surreal grain production was two years and looks forward to being what which turned self sufficient and so the cereal grains

such as race we'd been a few years now self sufficient usually means that the country no longer needs to import these take your food stamps it may not mean that everyone is getting sufficient of these in the country but to distribution thirty is the problem as we mentioned are and again known and has made great strides in the last to ten twenty years in improving its transportation distribution systems is so that day actually the great famine in west monroe in nineteen forty three was due in large part to the inability to move fluids from one part of the country into the famine the food was available in the country as a whole or probably was sufficient to report actual starvation nine nineteen sixty seven it was again a great got

some states but they're in and the distribution of food was very well organized recorders were important for this purpose but to the facilities were so that day so these are problems are are being resolved transportation the year availability of people trained and experienced in dealing with their food distribution programs and so on but dirt and to reverse something like six hundred thousand villages in india many of these over rather limited their marketing food marketing systems and of course the low incomes very low incomes most of the inhabitants present a problem if one tries to market is especially nutritious foods in many of these families of course grow

practically all of their food they might buy t and salt and so on but there is another that's problem of trying to improve nutrition and these people and subsistence farming people have grown food is our guest today on this land is your land is dr lester gave tetley senior nutritionist for unicef were talking about nutrition and food supply let's return for a moment to the problem approach protein and try to understand its importance and they've told us what protein is an essential eat why does important to the building of the body through the amino acids and so on what food provide protein and what kind of forms i'll come to that in one month the amistad that tourre among these many effects the protein deficiency man perhaps one of the most important is lowering the resistance to infections and the

nutrition interacts generally with infections taiwan exacerbates the other dimension but in may and at curie should've the high structures that inflation's going to men no and malnutrition in the developing countries generally young children particularly are and confronted to with certain infections of various types of almost continually about to occur from one before they go into another diary as or whatever it might be a respiratory diseases now unfortunately the infections interfere with the utilization of what protein is in the diet and that's another aspect of this problem of providing adequate protein because what might these suppression diet for a normal healthy show may not be for a child

continually dealing with these infectious diseases the season the problem really builds up that data does any action it certainly does yes now you asked about devout foods provide protein ours most foods actually except for things like sugar fat you have some protein and i mean no there are the closer range for example contain a substantial amount of protein something like seven percent of her and rice and ten or twelve percent in wheat corn this protein it does not have the year that kind of combination of amino acids that our how proteins do this is another one of the problems that we face actually for adult most of the cereal grains are

fairly adequate although a growing like corn is a markedly a freshman certainly no license and one cannot live on that protein low whereas and not an adult might get by fairly well stay with the protein or rice protein if there's enough of it for young child again the certain young growing child when dealing with infections this would be sufficient so we must in some way make up to freshen see and a traditionally in developing countries said means houses the green legumes have been used to balance out and this works for a while soybeans one of the libyans are a particularly good source of protein in fact said there are anthem formulas on the market today which contain only saw a protein that says for instance that can't handle know for one reason or another so there are ways to balance out the proteins as surreal as possible you know there may be a good

combination of meat fish in many of the animal proteins were very well in this regard though one can also do this combining their with vegetable proteins alone does to vegetable proteins or three or four that each one of which is not adequate nutrition way but the combination is quite adequate yes you talked about protein and naturally occurring foods is michael's agricultural proteins and you mentioned post meat and fish proteins other other kinds well protein food service the us a weird mentioned the year the legumes of beans pulses no means dried beans or contain something like twenty twenty five percent protein which is sir critic and level in cyprus have said compared tumor as a

race at seven percent your sugar and zero meat and a dry weight bases sir so i suppose the content something like seventy seventy five percent protein depending on how much fat is in the song but turn this fish local overweight kobe says her roughly a third isn't scam and speak no scandal as homo we also contains that's eleven and that vote in nevada and that it's still a very substantial amount no we don't he is a synthetic turf ivan watson yes these can be quite useful particularly in nerd some of these vegetable protein

formulations and mentioned the one that's a lot of publicity year one of these special mixtures for some moaning died of young children is that in kemper arena which was developed in guatemala ten fifteen years ago and in several countries in central america and south america and there are various types of and coupling of being actually manufactured and sold now in guatemala the mixture there is fortified with a synthetic amino acid lysine what is it twenty three uncovering it is a mixture of third cereal grain flour when an oil seed or in guatemala that happens to be a cotton seed power in colombia the oil seed portion as a mixture of soybean flower and garden seeds are so worried

we're we have a very clear use of the amino acids in a situation like that they are also used in a few places to fortify wheat flour does lysine is used today in certain specialty breads in the united states or an md owners the acclaimed red called modern bread which has fortified various nicknames including lacing nice easy easy as when a protein derivatives one of these amino acids and manchester which the body cannot make and therefore it has to be provided and diet either from the protein foods we mentioned or it can be furnished are directing directly as a year an additive you might say to a food product is not that there are cost considerations involved here and at the present time

their field study is being conducted in talese a blessing for the third week and nerd in thailand and for the issue of race to determine if possible or whether there are any year a measurable effects on a population if they basic food is so fortified with lacy for example not one of the complicating factors is that today in fact it relatively few people and he gets which don't contain somewhere animal protein even smaller market or some of the beans in these green legumes which do furnished slicing and therefore it'll be interesting to see whether any effects on the health growth and song of the population that can be measured with these efforts is it expensive to produce something like twice in gaza

than substantial to the cost of the food to which estimates of the native the cost i think the fortification of wheat flour would raise the price or the cost of that clover by something like eight or ten percent which is a special markets estimates of the neighbors to the cost if there were really large scale production and it has been estimated that might cost as low as little as fifty cents or purse and for years the form of a staple food that is a very significant amount for a developing country a service say where their total public health budget they may not even reached that amount per capita is so these things must be taken into account is there a difference in the nutritional value of the are officially produce proteins in the naturally occurring ones

i'm very low as far as we can tell there may be special situations in which earth the arid and you know i said maybe absorb more rapidly than any answers coming from protein food its work because the protein first has to be adjusted and so far as we can talk the moment this is this is not a major using this approach put poison on the procession identification our guest today on this land is your land is dr lester jay tapley senior nutritionist for unicef were talking about nutrition and food supply you mention in kemper arena is one of the

new foods imagine there are many others can you describe some tunes yes i'll be glad to do it i wonder if i may interject one common was we've been speaking to a considerable extent about to facts that are fairly well clarified as further requirement for specific immigrants is concerned and so on there are certain areas so however were there must be judgments made evaluation of various mayday and where we do not always have to be consensus among the first time the freshness that we just touched on amino acid fortification this is one of the more controversy over issues today it's a question of worry where you going to spend your money and some may say well here's a very neat way to do this surge of easily and that is not that simple quotation from the current fight me just quote it

and he said when it is not in our power to determine what is truth we ought to act according to what is most pro so that day i think will be getting into some points here where i'm at year showing that my personal bias say but i think it's important to do something about this tremendous problem of malnutrition well i think waiting until all the facts are and i'm not one hundred percent when you have a well informed by us it's very helpful thing to very much know you want to go you know into the into details of controversy i think it's important for some sense well this year it's sometimes said that to the performance of laziness it to wheat flour in that one doubles they utilize a bow protein in that

report now to this must be qualified because this may be true if that is the only source of protein and i and this is really the case as a mansion usual bits of animal protein getting teens and so on and this is why these real life studies so called her her being made in their twenties year thailand at the moment to see if one can know demonstrate under real life conditions that where there's a measurable effect know these desks are demonstrations is extremely year difficult to carry out a conclusive results for various reasons because infectious diseases come into the picture an animal experiments on not like you're going to some of these new foods that you

mentioned religion and carefully in a yacht now i should say that these products if they can be a reduced it relatively low cost if they can be delivered somehow to the year clientele that really needs them they can make a significant contribution i don't want to give the impression that davis is a magic solution to this is even as important as the basic supplies of conventional foods which we've been discussing a need so it's a socialist republic so sensitive that has caught saif and tsunami people in public and there were glad that it has as the iraqi group that he and kat institute which is a chance to have nutrition for central american panama and

guatemala was one of the pioneers the end of all things and the special foods for young children based on low cost ingredients they obviously developed in calvary is correct not since then there have been several dozen products abroad at least to the test marketing stage over the world relatively few of these are being marketed on is substantial scale now by that i mean the several hundred pounds a year or one or two thousand tons a year something like that actually in columbia and they're now besides the uncovering other three other special mixtures of this type general type that are on the market well unicef urbanization with the food and agriculture organization world health organization is assisting the country of algeria and marketing at a marketing and distributing the wealth or chose

a product called super mean just based on wheat and grains legumes other nutrients as hooper i mean it's super i mean there were amino acids and slip n word initiating solar projects in turkey you a un is a project in india which is a very interesting one were so that the it's going to take care and effort over a considerable period of time to get to get these products are well established and a bible basis for these fun food generally accepted among the people to whom they've been given welcome the ones that turn to accept it in the pot than julian in there so that no one has today consider the market indices been done more and more marketing studies

tearing through private setting flavors in some cases they're trying to fight pirates and to traditional pattern food habits knows the state equality a beating is quite important so even to people who were starving that the surge only two years i understand that an attempt has been made to produce high protein soft drinks is ridiculous yes there are a number of these are market based soy protein and in countries of the far east for example people like being a flavor it's a relatively year easy to gain acceptance of the some of these beverages know in the united states and in various other countries it's somewhat difficult to earn your acceptance of securities they were so in fear of their protein must

be while occur five or one can produce a flavored beverages which are quite acceptable number of these on the market and both developed and developing countries but this is one way of getting were the product to two people that buy beverages which will carry at least some some protein not only of calories man in the form for years one thing we haven't spoken about it much detail as the extraction of protein or the purification of a specific food to enhance the protein value of such as is done with beans or peanuts or something like that yes ms boyle singing flowers and they're usually these are de fatted flowers that is the year while

caesar processed for the oil and then know the de fatted flour or meal if it's not we find is relatively low cost there would be nutritional advantage is in many cases and they're leaving at least some of the fad an interactive what we call full fat so if our partially de fatted so far as a year commercial item and harvard the cost to those up take advantage of the economics of the fighting scores more processing the reason more expensive mostly well if one cannot to make a profit selling the fat in the skin is profiting from florida see all the profit not i shouldn't have the impression that a very large proportion of these quasi videos are currently going into human foods seize substantial amount but compared to the amounts that

to go to animal feed it's very versatile however this means that but there is this very fast to the source which which could be available for direct human feeding us and this week this will undoubtedly increases time goes on the use of these while studios in human foods let's turn for a moment to the role of the united nations and the problems with nutrition and world food supply can you describe to us the roles played by the various human un agencies involved in these problems yes sir so these agencies were established to independently of the united nations before the united nations was organized and they've been brought into relationship with united nations so that there is a coronation mechanism know world health organization is one of the older agencies

involved of course every important role to play from the only outside and they assist countries through her advice research and so on the food and agriculture organization he says countries with their food production but they have a much broader responsibility given their charter one part of that requiring that they try to improve human nutrition so it's not only a matter of food production my own agency unicef third desperately concerned with the problems of children and mothers but we work very closely with the some of these other agencies and trying to meet these problems with respect to protein since nineteen fifty five as many a special protein advisory group and since about nineteen sixty this has been a tripartite group sponsored by w a chill to fail

now the united nations as a whole is taking a very special interest in brooklyn protein nutrition these days and eighty un office of science and technology with its advisory committee on the application of science and technology to develop and her as organized a meeting of a special protein panel which will be held in a new york to advise and some of the the broad policy aspects to the strategy for trying to meet the world's proteins it was an idea of how much money you spent each year thirty years ago because first of all there's picking the un or as a total effort to

be very difficult to speak about the total effort but overuse get an order of magnitude from what the un spends on food problems for example this well i think a basic perspective total budgets the us or for budget is currently something like fifty million dollars a year and the budgets of her sister agencies every individual would be a several times that amount not all of it even though as a budget goes for writers dealing directly with attrition they've they deal with agricultural and fisheries production as a course of a year this includes the fibers for making ropes and yes things that star but certainly one could say that day is a very major part of the budget of that veil is devoted to matters which have some

relationship to nutrition the un development program supporters says funds available and it's beginning to wear spend some of these funds for matters rather directly related to depression and my own agency has said this is rather difficult to answer because the week we've tried to the new testament searching for executive orders to how much of their money as those depression era we we have certain know conservation projects putting food products a nutrition education projects these are relatively easy to categorize when one comes to health services and this sort of thing there are some nutrition while but no one can only make a very rough

estimate of the percentage are spent so that day offhand i would say oh we probably could be a fairly say that we've been spending the ten percent over budget done matters quite directly related to nutrition at them for very substantial proportion of the other also has collected within three years would you say that this perhaps something on the order of a half a billion to a billion dollars a huge factor well you see it in the un assistance funds are relatively small compared to the total bilateral efforts is so that ended the efforts of their foundations for example that all of this work and high yielding seeds supported by a rockefeller foundation fordfoundation over many years that all of these things add up two fairly impressive the total but still compared with the general economic development building

dams airports and so on and if what that one considers harms the a percentage of funds directly or indirectly voted to dealing with murders and intrusions extremely useful isn't so small as to make to make the problems even more difficult i would put it this way i think they're a great deal more money could be usefully spent and has to spend in dealing with these matters so much about the year domestic scene in the united states but you may have noticed there was is releasing the press they only follow up conference monday year white house conference on nutrition was held little over one year ago and done this followup small meeting the conclusion that although some new efforts have been made to deal with interesting problems in the united states far more needs to be done and get to some extent it comes down to the allocation of funds

i would like to return to the place that they say first that our guest today on this land is your land is dr lester jay template senior nutritionist for unicef were talking about nutrition and food supply we don't normally think of americans is having food problem but i think we do in many ways are not even thinking of the poor and underprivileged you don't have either for a proper a sufficient eyes although i don't mean to underestimate the problem i'm thinking more in terms of the kinds of diets that the average american hands looking at all of the excess weight we americans carry around and considering all the heart attacks we suffer from too much cholesterol and so on one can't help but feel that our diet is a poor one what you think such a wealthy and well educated country should have such a poor diet from nutritional standpoint and sometimes people combine that question with a question why do so many people keep on smoking cigarettes a day because i think there's a balance there

we have a free choice says society follow me gave her knowledge of what's involved in good nutrition fact that the f byrd considerably overweight this may reduce their life expectancy considerably but to have the motivation to to act it is to some extent were the scariest it's interesting to reflect on what the director of the american indians was in new england but when the poems came and i've done a little research on this and are i would say that to buy a large that wasn't too bad except

for maine where they lived dirt to a great extent and fish and game the diet surly in the rest of new england the indians were mainly a cereal grains the maze they like very much beans and peas various kinds of beans squashes fruits they sum game will protein some fish not a whole lot that is fish to fertilizer maze more than the consumption song but probably it wasn't too bad that they have many other problems infectious diseases that so one baby haired depressed friend their own funds and gave them a good start in that way and so on but probably the programs feel they were bringing to this land is much much better than his indigenous customs and out there but that that actually

happened i think it's a major legacy when noah there are though so the most important stories and that relationship of diet to heart disease have been done in the boston area people at harvard and others and day there are very strong indications was difficult as i said earlier to get very conclusive evidence that there are very strong indications that there the high fat diet says overheating know perhaps the kinds of fats and i probably are contributing to a great extent to certain diseases of her life this is a problem of the pilgrims bring their own again aesthetic taste for food to the indians really doesn't have too much to do with nutrition it's mostly a's questions that it needs the controversy over american diet was focused recently on the breakfast cereals a source of nourishment was coined that most breakfast cereals are badly lacking in nutrients yet we know that cereals on the most important sources of protein a new

term for the dichotomy between syria was a generic protein source and breakfasts that cereal has a stomach stouffer well there a number of factors that must be considered here it's it's basically true that if one word kloza says cereals and the way some breakfast cereals are other maybe some damage to do to the protein but don't as long as serve the pro to breakfast cereal is consumed with no say we mentioned is balancing effect is not going to let the hubble yes is processed nicely packaged editors surrealism may it will be more expensive than wheat flour corn meal or brian's on as has been pointed out in congressional hearings so the tour i think the industry and where the government and nutritionists on that is certainly taking a look at various factors if a significant

number of children are eating the sugar coated surreal as well now if there's been has been suggested in some poverty areas they may consume on these shows without know it has always things that we looked at and what the effect of the television promotions on children's diets and so on so dire i don't think one can make the sweeping statement that said this has been morrison fraud and a new breakfast cereals by large furnish a very considerable amount of good nutrition many of them are fortified with vitamins minerals sometimes approaching how much protein is a reasonable amount for breakfast cereal to have with or without no what's look at in those two ways well without i mean a food item that

should not say carry its own weight in protein depends partly only on the quality of the protein selectively the federal government guidelines in the united states as well as the year guidelines from the failed h o olof are certainly way so that if if the protein isn't the best available but say such as a protein in terms of the amino acid makeup or other animal proteins perhaps than one camera compensate for the us to some extent by eating more disparate sort to give another rough for range well we sit we're considering united nations work that furry a protein food to be useful as a supplement your diet you probably should contain mayor something like twenty percent protein or close to that all will put her food's with say fifteen

percent protein may still it depends on the situation sort of breakfast cereal this gives you some idea for what what day breakfast should contain trans into percent protein lesson that if you start with an corn wheat with about ten percent protein well or maybe that should be built up a movement and that it was hitting the fee increases the protein lucia silva the approaching in quality and quantity of some extent is it to make it through the more nutritious than the ground we seem to know a great deal about it effects of the foods on our health yet there are so many different kinds of diets that people fall thirty cents to be made out of this whole field of dieting well their money many diets that are followed of course medical advice professional advice and der there are

some reasons for recommending some of these nights on the other hand as i said earlier almost anyone can call himself nutritionist and made it rises or niger for more diet soda for use by others so which which may not the tucson based scientifically and i'm afraid that day saw the diet center distortions presenter of the patients and for certain reports on generations which area which may even lead to do dangerous situations for individuals for example we have seen the actual starvation by the part of individuals a lot of crash diets and this has occurred in new york city it is that happens that's an extreme so that i think your the best

thing to do is to rely on their professional advice medical advice the guidelines and federal health agencies and sourness to what constitutes a reasonable black lives now we're living in an age of enormous technical competence in rapid advance what's the possibility that we'll be able to fulfill the science fiction prophecies and be able to live on a few pills a day disappoint us all the vitamins minerals proteins calories and so on that we need to remain healthy well joe just isn't in the cards to go much beyond that kind of thing the day we can do for space travelers and so on in their smartest things have been done in terms of compact massive food sin for providing rees no i was going along with the essential attrition but there we we mentioned the year the basic requirements for calories water and so on this agenda knowing this so that while

he's served those can be used to provide certain subjects kurds that was to provide to nutrition well assuming that the calories were provided by some sort of bulk food would be possible to get the proteins and vitamins into a pill well the the new lower limit of protein is set let's say it serves something like thirty grams a day what's been full more liberal as a forty five grams of protein per day for an adult nsa upon hers says ford and fifty roughly where you're going to live a little less nerve center it's dry weight this well i'm fred river of time doctor teflon it's been very interesting the problems of nutrition world food supply remain difficult ones and it's clear that economic squeeze a major own solution i want to thank you for sharing your knowledge with us today i think it taught us a

great deal of yesterday's than dr lester jay tetley senior nutritionist for unicef for the best nine weeks we've explored together the problems of the air and water pollution solid waste disposal housing and nutrition beginning next week we'll begin a study in depth of the multifaceted world of transportation with a series of six programs will look into air and highway transportation rapid transit and transportation for the disadvantaged i hope you'll join me for this series on this land is your land you've been listening to continuing analysis of laughter land is your land and this land and milan in the gallo war new york thailand
