The "New" USDA Food Guide

posted Wednesday, 12 January 2005

Oops they did it again.  Well, the USDA has taken a crack at revising their food guide recommendations, as they do every five years, and what has all the latest science provided for in this most recent document?  Not much.

Going through the guide, I noticed that much of it was basically the same old advise that we've been hearing for year, but which either haven't worked, or more likely which have only resulted in the U.S. getting even more obese.  But let's look on the bright side for the moment - here are the only valuable additions to the recommendations:

  1. Avoid Trans Fatty Acids:  hooray, the USDA has finally come out with a recommendation to avoid these harmful things found in processed baked goods, shortenings, margarines, and some dressings.   The problem is that no specific recommendation is made.  Instead it is just recommended to consume "as little as possible."  But who knows how much is "little"?  Of course previous documents have basically said that there is really no safe minimum level, and hopefully the new labeling laws that will require these to be listed on labels will maintain the momentum that is motivating food companies to rid their products of these.  The other problem I saw is that Trans Fats were lumped in with saturated fats and cholesterol as items to avoid in order to avoid congestive heart disease.  Considering that plant-based saturated fats like coconut oil are now being seen as healthful in many quarters, and the fact that dietary cholesterol has been shown not to be a major factor effecting cholesterol levels in the blood, it's disappointing that Trans Fats were grouped with these other two.
  2. Increase fruits, vegetables, and whole grain consumption.  Most people would agree that vegetables and fruits provide a great source of nutrients.  With most vegetables these even come without the added risk of large dense carbohydrate or sugar loads that effect insulin levels and subsequently can cause health problems in some who are sensative.  Fruits are a bit more prone to having large amounts of sugar.  Grains, of course, are high in carbohydrates, but the recommendation is to increase whole grains, which have much more fiber which is not converted into sugar thus raising insulin levels.  However, if you look at the recommendations, they basically suggest increasing whole grains by about 200-300% from the 2000 recommendations, and to keep the refined (they call them "enriched") grains the same.  So while you may be getting more fiber, they are actually increasing your total carb load.

And that is one of my big problems with the recommendations.  Despite all the recent studies which suggest merit with decreasing carbohydrate levels, at very least refined carb levels, the new food guide recommendations still is basically a low-fat/high-carb diet.  Not that I expected anything different.  After all, the USDA's main purpose it to support the agriculture of the United States.  That agriculture is primarily grain-based, and so there is an obvious interest in promoting grains – and thus a horrible conflict of interest.  The USDA's food pyramid is nowhere to be seen within the current recommendations, but apparently it is in the process of being modified to match the new recommendations.  But I can't really see how it will change much.  The base will still be about grains, the top will still be fats and sugar.  Perhaps they will rewrite the portions recommendations so that it doesn't look like you need to eat 11 bowls of pasta per day in order to meet the requirements for grains, but we'll see.  The previous pyramid has developed a great deal of criticism except for the old guard nutritionists who basically use whatever the USDA puts out as their bible.

The unfortunate thing is that this will do nothing to educate or help those who know little about what to eat.  Their recommendations are a set of basic guidelines (misguidelines if you ask me) which don't really teach people why they should eat a certain way, but just tell them to.

I was pleasantly surprised by this round of changes to the dietary guidelines, although I agree that there could certainly be more change and improvement. One of my main criticism's with the guidelines is that they do so little to educate people on them. No wonder we're in the shape we're in in this country.

I have a theory that, to me at least, seems to explain why PP works for me and not for my friend. Yvonne primarily eats fruits and vegetables when she wants to loose a few pounds and says she feels absolutely great. If I did this I would faint. I need meat. I need to have some protein with every meal. I've run across a few other people like Yvonne. And there are obviously others as the "carb proponents" out there are many and there books sell very well. Anyhow, my theory is as follows. We all decended from one of only a few tribes of early (wo)man. If you look here, there is a better explanation of this here http://www.oxfordancestors.com/mos_offer.html

Anyhow, long story short, possibly some of these tribes were more agriculturally based alot earlier and therefore are more genetically predisposed to handle this type of a diet. I would say the larger majority would be meat eaters primarily due to the abundance of fatness in the western world that is basing their food intake, at least in part, on the Canada Food Guide or the US equivalent.

Just a thought/theory but it's the only thing I can think of that explains this discrepancy. Comments?

Shari, thanks for the post. I agree that different people have different sensitivities to higher carb loads. For example Pima Indians seem to be very suseptible to diabetes, heart disease, etc. when eating the same diet that doesn't cause nearly the same risk for caucasions of Northern European dissent. But I suspect that while some of us CAN eat more carbs without experiencing the extreme risks that some others do, that doesn't mean that eating a diet containing mostly those things will be OPTIMAL for us. We may not experience problems like obesity that are outwardly obvious, but then all of a sudden at age 50 a diagnosis of heart disease or something like this may be a wakeup call... It's one thing to feel great and "lose a few lbs" eating only fruits and veggies for a few days, but I don't know if this says that much about what we should be eating on a regular basis for optimal health. Our modern metabolisms are generally so screwed up, that I wouldn't trust anything aside from long-term approaches. Unfortunately long-term studies haven't really been done. The longest I've heard of were a year, and I know that many of these have some big flaws. But I write about all this in much more detail in another entry: http://twelveblackcodemonkeys.blog-city.com/read/916840.htm

You're right about the studies. I think it's time that some non-partisan studies were done with regard to this. In fact it is probably an emergency at this point due to the epidemic of overweight children of late. This is a real serious problem because I think it's an accepted fact that if you have weight issues as a child you are probably going to have the same problems your whole life. Something about the formation of fat cells. I can't remember the exact explanation. I have read at least a couple articles that suggest this may be as dangerous as smoking and has been linked to at least as many serious diseases. It's really sad.

This comment is to Sheri. In reguard to your first posting, involving the different need of different people, there is a book called "Eat Right for Your Type". It explains different digestive needs for different people based mainly on their blood types. I found it an interesting read, and it gives a pretty good theory on why different people need different things. I personally know a few dietitians who have used this system and had great succes with it. You might want to check it out.

Soloman, what kind of references are you looking for?

Regarding Eat Right For Your Type, we've discussed this book on the Protein Power Bulletin Board somewhat and the experience of members who tried it were mixed. It seems like if you have a type that suggests you eat a primarily low-carb diet, you tend to do well (as many people do), but for those who it was recommended to eat a more carb-based diet, they did not tend to have a good experience, so my thought is that blood type is not a very good indicator of diet type. I haven't read the book and don't know if the author has done any studies, but if he has I'd be interested in seeing them.

You poor, poor, misguided people. And you moderators, I don't know if you were just misled as well or if you know better(if so, shame on you for exploiting people for your own profit). I am a student in the field of health promotion at the university of northern Iowa. I a have an emphasis on nutrition and if there is one thing that I have learned it is that NO DIET SHOULD EVER DISCLUDE ANY KIND OF FOOD GROUP!!!!! Your body needs every kind of nutrients in specific amounts. How it works is that you get energy from Carbs, fats, and proteins. The main sorce is Carbs. However, in the absence of carbs your body picks up the slack by using more fat and protein, however, the majority of that protein is not, I repeat, NOT from protein recently ingested but from lean tissue(aka muscle!!!). So when you go on a low carb diet all you are doing is forceing your body to use muscle tissue for energy instead. At the same time, fad diets (like this one) usually don't encourage water consumption and that is were a large amount of the weight loss comes from. From water loss and muscle loss. Then, when someone has gotten down to the weight that they think is apropriate for themselves they often go back to their old habits and start adding on muscle. So in affect, they replaced muscle and water with more fat! I know this message will soon be errased but I can't help it because I know better. I also realize that alot of you will question me just because I am still in school(just a second semester junior). Well, I challenge the moderators to post their credentials. I bet these doctorates that they are talking about are not so amazing as they would make you think. Oh yeah, by the way. I can check these out so make sure that you are telling the truth. thanks and good luck to all you dieters out there. If you have any questions just post it on here and I will come and check it later. Brad

Poor, poor Brad. I will cut you some slack because you sound very youung and naive. The study of nutrition is one that has some pretty strict guidelines for what people should and shouldn't question. My big suggestion to you is this: question everything you are taught. Why should no diet exclude a food group? Is there hard evidence - double blind studies - backing such claims up? I'm not sure where you are getting your claims about muscle loss from low-carb diets? Can you name a study, any study, so that I can read this? Probably not. Probably it is propaganda spewed by the nutritionist/dietician authorities who have something against anything labeled low-carb. Please, prove me wrong. But these same people have been trying scare tactics like this for 20 or more years, using rhetoric that isn't based on science, or if it is, it's misleading. For example, the myth about higher protein being bad for the kidneys. This isn't born out in any study, it is simply an inference or extrapolation from the fact that those who have existing kidney disorders have problems with larger amounts of protein. Question everything you are told. Look for studies that prove everything. Without such studies, you will simply be a politician towing the party line, which may indeed be very wrong and detrimental to those you are trying to help.

And what are you talking about "moderators" and "credentials." If you look at the About Me section of this blog, you will see that it's written by one person, me, and I don't claim to have "credentials." My "credentials" are that I've read a lot of books and studies and online about nutrition, health, diet, etc. I've also went on many diets in my life and so far low-carb, adequate-protein, minimally processed eating has given me the biggest health benefits, makes me feel the most energetic and has been the most SUSTAINABLE. I've been doing this for over five years, and while according to you all of my muscle and organ tissue should have been consumed by now, it hasn't, and I'm in fact feeling quite good! Have you actually followed people who have been on this kind of plan long-term? How about short term? Have you compared it to other plans that are low-fat or "balanced"? I've done the low-fat thing, I've done the "balanced" approach via Weight Watchers, and while I've lost weight, they were never sustainable.

Before you go shaming others or calling people uninformed, perhaps you should check your arrogance at the door and actually ask some questions instead of just accepting whatever the textbooks say as fact, because guess what, much of what you read could be dated or simply incorrect. It assumes a particular stance towards dieting and if studies contradict this stance, they simply aren't included because it would hurt the argument.

In the mean time I'll be waiting for a list of studies that prove your alarming statements from above.

I will have to get back to you on studies(finals week), if I remember, I will look them up over break. As for propoganda from authorities, what in the world would they possibly have to gain from saying something wont work if it is proven to be different? Doesn't that go against all the laws of scientific reasoning? They don't have nearly as much to gain from this as say, somebody who starts a diet plan, and makes lots of money off people who don't know any better. These are the same people who are running these studies! They are educated in the functions of the human body, they didn't just go around the internet reading random things that they have come across and taking them for absolute truths when anybody, and I mean anybody can put something on the internet and make it seem true whether it is or isn't. I have been running tests on this diet, it is my project that is part of my semester test. I was trying to figure what all attracted people to this diet when I came across your website and saw what you were telling people. Now I am pretty sure that you are doing this without knowing what kind of consequences can be. Oh, and by the way. You say you have been doing this for five years, big whoop. That is not a long time, that is not true long term effects. I will admit that more long term research needs to be done, but we wont be able to for a few years and so far it isn't looking to good. By the way, you guys are majorly downplaying the affects of Ketosis, I have seen what that can do to people and it is not pretty. So, don't just call me young and naive, because it is obvious that you have a lot to learn as well about what healthy nutrition is. Don't worry, I do to. I do question what I have been taught, I did this project and so far it is proving what I have been taught to be correct. Brad

I think you phrase it in the wrong way - "something to gain. " I don't think it has so much to do with gain as opposed to perhaps defending reputations. Those who invest their careers in certain theories have a vested interest in those theories being accepted and correct. Scientists, despite their air of objectivity, are still humans and thus are subject to the same human foibles as anyone else. While there may be some areas of agreement when it comes to nutrition, there are many things that scientists disagree about - be they nutritionists, doctors, etc. There are studies that purport to prove all kinds of things, which just gives me the idea that it's very easy to create a study to show almost anything. You can bend statistics very creatively, and I've seen many studies where the authors actually decide to discount the actual numbers because they don't make sense based on their expectations! It's amazing, but scientists, especially around health and nutrition, come with certain expectations based on what they've been TAUGHT - like you. So when a study seems to discount this, instead of looking at the foundations of what they think is known fact, they discount the evidence.

As far as those who write books, I love this little dig that is always given. It's like if you write a book and make some money, you are immediately tarnished. Doesn't matter if you also have been practicing medicine and seeing patients for 20 or 30 years, helping them to get healthy. Nope, profit from sharing your insights - especially if those are related to low-carb or something else that nutritionists dislike - and you are tarnished forever. Not to mention tons of nutritionists put out their own writing for profit. Perhaps, though, it is just those who do not adhere to the approved guidelines who deserve rebuke for their profit, or just those who profit "too much."

As far as "reading random things on the internet" I'm afraid you're wrong again. I've actually read many books as well as actual studies and articles written by nutritionists, doctors, et al. The diet books I've read range from low-fat titles from Dean Ornish and Michael Mirkin, to low-carb such as Atkins and Protein Power. If you haven't read Protein Power and Protein Power Life Plan, I urge you to do so. These books are heavily referenced and punch holes through many of the fallacies that I'm sure you still adhere to. Have you actually read these books? I myself was not at all impressed with Atkins because it doesn't really approach things on a scientific basis. It's just - hey here's what you can eat and still lose weight. Whereas the Protein Power books describe in detail how eating fewer carbs is healthier, and much more. How the physiological processes work, the metabolic pathways, etc., etc. If you truly want to educate yourself, at least look at the highest example from the "other side" and not just what the most popular low-carb diet book is.

No, in the scheme of things, five years is not a very long time. However, how many "long-term" studies were there on low-fat when nutritionists started touting it as the proven healthiest way to eat? My point is that there's a lot of hypocracy out there. One can use the lack of long-term studies to tell people not to eat a particular way, but then one has to basically say there's no long term studies on any particular way of eating that proves it is the "most healthy." I would love to see longer-term studies on all types of eating plans. My hunch is that the best way to eat, as described in Protein Power and other books, is one of minimally processed, whole foods, meaning meats, fish, vegetables, fruit, nuts, and seeds. Limited if any grains or legumes both of which seem to have links to autoimmune disorders (alergies, arthritus, asthma, etc.), and generally getting an adequate amount of protein in order to support the body's needs for repairing and building new tissue, and with a carbohydrate level low enough not to encourage excess insulin production. Oh yes, avoiding trans fats and also poly unsaturated fats.

As far as Ketosis, do prey tell what does it do to people? I have yet to see anything published about its ill effects other than bad breath. Or are you again showing your ignorance by confusing it with diabetic ketoacidosis which is a seperate issue? While Atkins is big on ketosis, in Protein Power it is a non issue. They do not believe you have to be in ketosis to lose weight and neither do I. I do not measure my ketones and have never experienced the classic smells of ketosis, but there's a fair amount of information about ketones and how in a healthy individual they are not just not dangerous, but actually the preferred fuel in some cases. Speaking of which, ketones are a natural product of fat breakdown, so we all have at least some ketones in our blood at any given moment.

As far as your project goes, I'm glad you are "proving" that what you've been taught is correct, however, just saying this doesn't mean much when you haven't even said what your project is, what methods you are using to prove what, what the actual data is, etc. I would love to poke holes in your project, but of course I can't do that since you've already told me that it's a done deal and who am I to question that? Just some guy on the internet who hasn't studied nutritional science from a textbook in a classroom. Whereas you are the designer of that "project" and someone who has actually read nutritional textbooks in a classroom. Hmmm, I guess you win!

Yeah high, this is going to be short because I am still studying for finals so I just going to say a couple quick things. First off, quick trying to just say that I am ignorant please, because I don't beleive that you know everything about my background and taking quick shots like that just is uncalled for and pointless. As for Ketosis, what it does(and no, just because you are on one of these diets it doesn't mean it is going to happen, it just means that it is more likely) is builds up in the kidneys and has gotten to levels in which the kidneys will shut down and will have to go onto dialises. it also affects your liver in a similar fashion. Well, that is all that I have time for at the moment(really, I don't even have the time I took to write this), I will continue this later. Brad

Sunday, 11 December 2005 7:27 am

Brad, your arrogance amazes me. I can't call question your knowledge of certain things, but you can do that of me? Why are you exempt from question? Just because you are studying in college? As for Ketosis, if it did such things to the liver and kidneys, wouldn't we be seeing huge numbers of people with symptoms or at least blood tests that showed abnormal kidney or liver function. True, not all diets involve ketosis as a requirement, such as the one I am on, however, the most popular low-carb diet does require it, and it's also been around and quite popular for 35 years. Please show me a study that finds in a otherwise healthy person (ie non-diabetic), that ketosis produces harmful effects? Again, simply stating these things as fact will not get you anywhere in the real world. You need to show how studies back you up.

It's convenient that your only comments leave out any mention of this project that you claim is proving your backing, but that's ok, I'll let you claim finals as the reason. I do look forward to reviewing this project in detail though, when you dain to make it public...

Dude, what is with the personal attacks. First off, I have three tests this week, I will be done soon. So when I am done(and find the time because this is nowhere near the top of the list of things to do) with other things that I have to take care of. It is not like run a website or something of that matter, it is not that important to me. As for what you said on Ketosis, it is a common side affect that it builds up to dangerous levels even in people who aren't on a low carb diet but are still consuming large amounts of protein. It doesn't happen to everyone, just like because someone may consume large amounts of cholesterol doesn't mean that that person will have a heart attack. I will post my short list of negative side affects later when I have more time. Well, bye for now, I look forward to reading your next page long post that you will probably write in rebutle.

Sunday, 11 December 2005 5:53 pm

Hey, DUDE, I like it how my one comment about your arrogance becomes a personal attack, whereas all the previous entries by you are simply reasonable debate. Look back. Even in your last message there are subtel digs about "its not like run a website"... "it's not that important to me." Or your comment about the length of my posts?

Anyway, aside hypocracy, I still haven't gotten the info from you I want. I'm glad you have the time to take off to post these short comments with little substance but lots of indignation, but not a little more time to post something that actually gives some information.

As far as ketosis, yes, for diabetics, it is dangerous, as I noted above. However for non-diabetics, there is nothing deleterious about ketosis. Aside from which, this whole argument is silly because I don't even subscribe to the belief that ketosis is necessary to lose weight, but some people can go into ketosis. As long as they are not diabetic this is not a problem.

Looking forward to a more substantive discussion once your more important obligations are taken care of.

Try an eating plan based on your metabolic type, in which there is a recommended plan for any specific m. type. Dr. Mercola has a book called: the total health plan, that is an interesting read. Carbs, especially breads, grains, etc... turn into sugar in the system, & seem therefore to be something to avoid if you have any blood sugar disorders such as diabetes. They are also known to hinder losing weight if eaten regularly. It has been suggested that one should get their carbs from veggies & more complex sources for a more balanced system.


17. Levi Wallach left...
Thursday, 27 April 2006 1:48 pm

Madison, while I agree that most grains are not the best choices for most people, it's probably not for the same reasons. EVERY carb (except for fiber and varying degrees of sugar alchols), and a varying percentage of protein converts to sugar in your body. While that in and of itself can cause a problem if you eat a large quantity, the criticism I'm more concerned about with certain grains is the theory that they may be implicated in autoimmune disorers like arthritus, asthma, allergies, etc. That is the big reason I try to stay away from them, although of course they also don't normally fit into my low-carb way of eating. Rice is one of the grains that apparently is not tied to these disorders, so I will occasionally eat a small amount with sushi, but in general stay away from grains.

By the way, isn't it interesting how Brad kept promising to come back after finals to write more about his research and then just dissapeared. Hmmm, makes me wonder if he was really doing research. Or maybe his research ended up not giving him thr results he wanted and so instead of changing his views he's decided to ditch his research as having some inherent flaw. Unfortunately that seems to be what a lot of people do when faced with evidence that goes against their assumptions - they bend over backwards to rationalize why the evidence is wrong because their assumption must be right. Humans can be funny animals, sometimes, even those who describe themselves as dispassionate scientists - politics, ego, and reputations often trump truth, even in this field where it is supposed to be paramount.

Levi, At the present I'm not real close to eating the way I should for optimal health, but am working on improvements. I visit Dr. Mercola's website alot, among others, & read his research & observations which, I have to say has helped point me back in the right direction. One thing I've noticed is that if I munch on toast or cereal in the morning, I feel like sleeping within an hour or two, & sometimes feel a little dizzy, as oppossed to when I have protein & veggies, which seems to give me more of a balance of energy & help lessen my fatique level. I have to wonder if I have a blood sugar imbalance. (I'm working on that too, just in case). I have noticed less aches in general when I stay away from grains as well. As for Brad. He's probably a new student in the subject,(compared to someone who's done years of research, & has documented proof to back it up), into the research he done, hyped about it, & because to him, he feels he's learning so much, he defends it. Many times when some one believes something to be true, they get a bit emo when some one else contradicts those beliefs. I think it's just part of the learning proccess, & different people arrive at truth at different paces. Guess that's what makes the world keep going 'round. I remember times feeling that I knew so much about certain things & was so hyped about it, that I had alot of drive (though I'm not knocking drive) to tell/share what I believed with the people I love, & now, when I think back, (though I may laugh), sometimes I really feel embarrassed, even a little ashamed for trying to push my viewpoints on them. I just didn't know what I thought I knew, & was trying to be good for them. 10 yrs from now I will have learned more & I'll feel silly for some of the things I say now. Brad is journeying through life as we all are, & we are all sort of "in school" so, if he believes those things, then that is the direction he will travel until he learns something else that affects him, & it's time for him to move along from where he is at. I can't say that his taking pot shots is real cool though. It reminds me of little kids who stick their tongues out at each other & make dirty faces. Seems like he's real emo.about it. Some times fires, though they might burn brightly, & others get riled up, burn out real quickly. There are other possibilities though, one being,(& this might sound crazy),I've read/heard about people out there assigned to search the web & cause havac for particular sites if they have to do with anything contradictory to what the government wants the people to think, or need the populatuon to believe. (I could go into more detail, but that's a whole other story). Just look at Kevin Trudeau, Dr.Lorraine Day, & others who try to get what I would call good onfo. out there. From what I've heard they purposely try to stir up trouble to raise the stress level of the ones managing the websites they target, in an effort to get viewers to mistrust them for one thing, & to bog down their minds with the situation they're trying to create, so that those who manage these sites can't concentrate effectively enough at their work, & therefore will have a weak site, or eventually get so frustrated that they give up altogether & shut down their site. I for one am glad to see those sites out there & hope people don't let "the heat" shut them down.

Madison
