Healthier Scammers

While on Facebook today, I saw an ad for a website called Healthier Post claiming to promote health and weight loss. I told you the other day that I could find something to make me face-palm every day of the week! They're out to sell you a supplement of course, and I am sure that there are probably hundreds of others just like them, but I'm picking on them because I saw their ad.

I perused their website, and honestly I wouldn't have bothered writing about them, except for the fact that they are touting patently false information, and some of it would be almost comical, if it weren't for the fact that this information will make you sick and could kill you. Now, some of the information on their site was reasonable. They advocate avoiding sugar and processed flour. I think we all agree those things are not good for you. But how about this?

This is a screen capture from a page on their website, text hi-light is mine

The idea that your body cannot process fats and oils is one of the most absurd things I've ever read. And I was an Art History major for a while, trust me when I say that I've read a lot of absurd things. I'm not going to get into the biochemistry behind fatty acid metabolism, mostly because I barely understand it myself. (If you want to learn more about biochemistry as it relates to health and weight loss I suggest checking out Hyperlipid's blog, as he knows more about this stuff in his pinky finger, than I do in my whole brain.) What I will say is this, it's very basic science to understand that your body doesn't know fat you eat from fat you store. It's all fuel to your body. If what they said were true, and your body could not "process" fats and oils, humans would not have made it out of the paleolithic. If there is nothing to eat, what do you think your body runs on? It runs on fat released from your adipose (fat) tissue and ketone bodies manufactured by your liver. Your brain can use ketone bodies for fuel instead of glucose once ketone levels are sufficiently high. Research has shown that brain cancer patients could benefit from zero carb diets because brain cancer likes glucose but cannot use ketones. Go figure.

But it gets better! On another page they tell you to avoid the following foods in order to lose weight. It sounds almost like the standard government advice, but the text below has more ridiculous assertions that have no basis in biochemistry.


Another screen shot from their website, emphasis mine

Three things here, first of all your body doesn't view "natural" sugar (whatever they mean by that) any differently than any other sugar. Sugar is sugar. Glucose and fructose are all handled in exactly the same way by your body and it doesn't matter what the source is. Next they say that fats and oils are toxic. Apparently they've never heard of essential fatty acids. You know, those things that are required for you to continue living. I don't know about you but I like living, and I like to eat fat too. Now lastly, they say that you should cut these foods completely out of your diet. You know, you'd almost think they were advocating veganism, but they're not. A few paragraphs down they say, "...you should eat proteins like steak, fish, chicken, and eggs to keep you strong and give you the energy to exercise." Are they just stupid? I'm not entirely sure, but a great portion of steak, fish and all of egg yolks are fat. Maybe they're just uneducated, out to sell you a product, and have copy and pasted various (and thus contradictory) text from around the web.

The moral of this story is, if a website promotes "fast" weight loss, advocates colon "cleansing," wants to sell you something to lose weight, and does not understand that just because something is "natural" doesn't make it good or safe, do like Monty Python and RUN AWAY!

Sugar Crash

Today we went out for lunch. We rarely do that. A friend of ours runs a little restaurant and we ate there. I have to admit that I had way too many carbs for lunch, and afterwards felt like crap. I would have probably been fine, except our friend always wants to give us desert, and then how can you not eat it? That would be rude. So anyway, I was tired and jittery all at once. I walked about a half mile after and that helped a lot though. This is why I don't like eating out. I mean, before I started this, I enjoyed eating out once in a while. Now, it's nearly impossible to do so with some exceptions. I mean, you can get a burger and toss the bun. Or you can get a steak. But you have to be at the right place for that. And even then, you're probably consuming vegetable oil, since that's what the restaurants cook everything in. It's so much easier just to cook for yourself.

On the way home I heard an ad for some company that will remove your fat, as in plastic surgery. I thought, why don't people just stop eating the carbohydrates? And then I remembered. They'd have to be told the truth. And they'd have to want to make the decision to do so. Like an alcoholic, carbs can be addictive for some people, and even if they're diabetic and it's killing them, they won't want to give the carbohydrates up. A piece of cake is more important to them than their health.

The Misconception of Natural Sweeteners

Lots of things are natural, meaning they occur in nature. Arsenic, cyanide, uranium, deadly nightshade. That doesn't mean you'd want to eat them, or even come into contact with some of them. I don't know how many articles I have read decrying the evils of High Fructose Corn Syrup, and yet saying that regular sugar is fine. Now, I'm not saying that HFCS is the same as sugar, it's not, by a long shot, however, neither of them are good for your health. Other naturally occurring sugars are no better, like honey. Sugar is sugar, and the glucose spikes your blood sugar while the fructose portion damages your liver and raises your triglyceride levels. That includes the fructose in fruit.

We have articles in newspapers like this one, since it's Valentine's day:
"But let's not make fructose the only bad guy here. The real problem is our consumption of all added sugar. Naturally occurring sugars like fructose, found in fruit, and lactose, found in milk, are valuable nutrients."
Overall, this article is better than most, but still has some problems. It fails in that it differentiates the fructose in fruit from the fructose in HFCS. There's not one iota of a difference, with perhaps the exception that if you ate a piece of fruit you might get less than if you ate something laden with HFCS. The problem is, our modern fruit has been bred to be bigger and sweeter. The sweeter it is, the more fructose is in it. Also, the fructose found in sucrose (table sugar) is also the same to your cells.

The problem is, they can't let go of the notion, that "everybody knows it's common knowledge" notion, that fruit is good for you. Five hundred years ago everyone knew the earth was flat too, and the center of the universe to boot. We all know what happened to Galileo when he dared to suggest otherwise.
"Does this research mean that eating fruit will increase your risk of heart disease and diabetes? Absolutely not."
That statement may be blatantly false, considering the study out of New Zealand that I wrote about last week, that I might add no American media picked up (good thing I didn't hold my breath).

Another newspaper article, also acts like natural sweeteners aren't a problem:
"While the massive amount of high-fructose corn syrup consumed by many people isn't a great choice, a more moderate amount of natural sweeteners can be a wonderful complement to a healthy diet."
What exactly is their idea of "moderation"? Eating 100 lbs of sugar a year versus the current 150+? Taubes wrote about this in "Good Calories, Bad Calories" and it seems from some reports by doctors who were in Africa and other colonial places a hundred years ago that a sugar intake of approximately 60 lbs was the cut off point of "too much". After consumption rose above that level, and after a time frame of about 20 years consuming such levels, they saw diabetes and metabolic syndrome begin to develop, along with all the other western diseases that go along with them. And really, it might be that a lower consumption just means it takes longer to develop metabolic problems in some people, or maybe even in most people. I doubt seriously the authors of these news articles imagine that we really might need to restrict our sugar intake to a minuscule amount to avoid developing disease.

The first article I cited did have a great line in it:
"If we really looked like what we eat, most Americans would look like kernels of corn."
There's the truth if I ever read it.

Parrot: "I'm a doctor!"

Are writers incapable of researching stuff before parroting what they're told? Are editors? I hope some are, but it seems like the majority aren't.

For example, this article from US News states that eating too much sodium leads to high blood pressure. Except it doesn't. A dietary reduction in salt can lead to a whopping 1.1 to 5 mmHg at *most*, if you believe meta-analysis. I'm completely underwhelmed. Most high blood pressure is genetic and diet has very little to do with it. If your blood pressure is high you need medication. That's about the only thing you'll hear me say that you need medicine for.
From the article:
"As a family doctor, I've observed that more and more of my practice is devoted to preventing and treating nutrition-related disorders such as high blood pressure, obesity, and diabetes. So I had hoped that the new dietary guidelines would provide me with concrete strategies for helping change my patients' eating habits for the better."

Why don't these doctors do some research instead of relying on Big Brother, er, I mean the government to tell them what to tell their patients? I guess they're too busy to read anything. Or to think for themselves. I find all kinds of interesting information simply searching Science Direct or even google. If they'd recommend to their patients to eat low-carb or paleo, most of their patients' health problems would improve and/or resolve themselves. In fact, I'd bet money on it. I'd even bet a million dollars. I could definitely use a million bucks.

Maybe they're scared? Taubes said in Why we get fat that no doctor was ever sued for recommending a low fat diet. I guess the acceptable killing of patients via the low fat nonsense is preferable to a lawsuit.

Unintended Consequences: Salt Intake, Obesity and Insulin Resistance

When William Banting wrote his Letter on Corpulence in 1863, the medical community attacked him like piranhas in a lake filled with hemophiliac swimmers. Gary Taubes describes this best in his book Good Calories, Bad Calories:
"The medical community of Banting's day didn't quite know what to make of him or his diet. Correspondents to the British Medical Journal seemed occasionally open-minded, albeit suitably skeptical; a formal paper was presented on the efficacy and safety of Banting's diet at the 1864 meeting of the British Medical Association. Others did what members of established societies often do when confronted with a radical new concept: they attacked both the message and the messenger. The editors of The Lancet, which is to the BMJ what Newsweek is to Time, were particularly ruthless. First, they insisted that Banting's diet was old news, which it was, although Banting never claimed otherwise. The medical literature, wrote The Lancet, "is tolerably complete, and supplies abundant evidence that all which Mr. Banting advises has been written over and over again." Banting responded that this might well have been so, but it was news to him and other corpulent individuals." [emphasis mine]

It was news to me as well. No one told me that I should eat that way. But what else was news to me is this, apparently restricting sodium intake can cause and/or aggravate insulin resistance. In a country with what some call a "diabetes epidemic" why are nutritionists still advocating restricting sodium intake? Especially when lower salt intake does little for lowering blood pressure, which is why it's pushed on the general public in the first place. One review found that a reduction in dietary sodium would amount to systolic blood pressure being lowered by a whopping mean of 1.1 mmHg, and diastolic by an even more underwhelming mean of 0.6 mmHg.

I suppose part of it may be because it seems a lot of the studies done were published in a journal called American Journal of Hypertension over the last 20(!) years, and I guess the "experts" and the "nutritionists" don't read it. I mean, don't read period. Because if they did, they'd have read Taubes and the plethora of other studies that would tell them that what they're telling people is flat out wrong and is killing them.

Not only can salt restriction apparently be bad for insulin resistance, but one study showed giving people more salt helps alleviate it and makes them more sensitive to the insulin.
"For the group as a whole, urinary sodium excretion increased on sodium chloride to 267 ± 118 mEq/day versus control (placebo) phase of 135 ± 53 mEq/day, P < .001. Total glycemic response in the oral GTT (area under the glucose curve) was 8.0% lower during sodium supplementation, P < .001. Secondary analysis revealed that the effect of sodium was noteworthy in 1) type 2 diabetic subjects (n = 8), 2) sodium -sensitive subjects (n = 10), and 3) nondiabetic subjects receiving antihypertensive drug treatment (n = 6). The total insulinemic response to oral GTT was also lowered by sodium loading among diabetic subjects. Thus, an abundant sodium intake may improve glucose tolerance and insulin resistance, especially in diabetic, salt-sensitive, and or medicated essential hypertensive subjects." [emphasis mine]

(The effect of sodium supplementation on glucose tolerance and insulin concentrations in patients with hypertension and diabetes mellitus, from the American Journal of Hypertension, Volume 14, Issue 7, July 2001, Pages 653-659)

One of the most recent and largest studies from the journal Metabolism, took data from 152 healthy people who were prescribed a high or low salt diet. It too found that a low salt diet was associated with increased insulin resistance.

People are expensive to do studies on. You have to pay them to participate. Lab rats on the other hand are cheap and you don't have to pay them anything and you get to dissect them when the study is over so you can obtain even more information on what was going on physiologically. One rat study found:
"In the present study, higher body weight, blood glucose, plasma insulin, triacylglycerols (triglycerides) and cholesterol, hematocrit and heart rate were observed in animals on low salt intake compared to the normal-salt group. Blood pressure and glucose uptake were lower on low-than on normal-salt diet." [emphasis mine]

(Insulin resistance due to chronic salt restriction is corrected by α and β blockade and by l-arginine, from Physiology & Behavior, Volume 88, Issues 4-5, 30 July 2006, Pages 364-370)


If you've been paying attention, insulin resistance (and by extension diabetes) is associated with obesity. Apparently one study showed that restricting salt intake in female Wistar rats predisposed their female offspring to obesity.

Most of the studies say that more and larger studies are needed. As mentioned above, studies are expensive. There were some studies in humans that found the opposite or no correlation between salt intake and insulin resistance, but of these I saw, they used a very small number of people, in one only eight and were very short term. That's not enough subjects or time to get meaningful data. We need large studies with lots of people, that way individual variation is controlled for. All of the rat studies I found showed a correlation with low salt intake and insulin resistance, and since rats are cheap, there were more rats involved than people. It may be that some people are not as effected by low sodium intake as others.

So here we have unintended consequences, in that nutritionists are advocating you messing with your diet for what might amount to a slightly lower blood pressure, at the expense of something else completely unforeseen. How do you like being an unwitting participant in one of the biggest health studies ever made? Because that's what you are if you live in any country that follows the dietary guidelines set forth by the USDA. You may think you have no problem eating as you are, but the food manufacturers have made it a point to remove salt and fat from the food they sell you. So unless you are making a concerted effort to add it back in, you may well be deficient and not even know it.

Common sense is indeed not very common. If excess salt intake had anything to do with ill health, the human race in western Europe and elsewhere would not have survived into the modern era. Last I checked, prior to the 20th century, people did not have refrigeration and used, get this, salt and LOTS of it to cure meat. I doubt there's any way to find out exactly how much they consumed, but it was way more than we do now. And since we don't have reports that medieval people were dropping dead from stroke or heart disease (plague is another matter), I dare say the salt wasn't a primary cause of mortality. Of course, absense of evidence is not evidence of absence, and maybe they just didn't live long enough for the salt to kill them.

In the beginning...

In the beginning God created journalists. And they were real journalists, in that they rooted out the truth and gave it to the general public. But then somehow things changed, as they usually do, and journalists became beholden to corporate interests. And they stopped telling you (the public) the truth and began telling you what they thought was the truth. Or rather, what they thought ought to be the truth. It may not have been entirely their fault. They were lied to. But instead of investigating whether what they were told was a lie or not, they accepted it at face value. Perhaps the scent of money to be had made them shut their eyes and their ears and accept the lies. I suppose the glint of silver does that to a person.

We know it's a lie. Gary Taubes has shown us all that. The man deserves a nobel prize.

What pisses me off, is that I was lied to. Isn't that how it usually is? Humans are very self-centered creatures for the most part. I was told all my life that I ate too much, and that was why I was fat. In my case though, I now know that's not true and I can do something about it. I've lost about forty pounds since I read Taubes' book last May.

The same can't be said for the millions of dead. That's not hyperbole either. Almost everyone who has died of complications from diabetes in the last thirty years might have been saved if they'd only been told the truth, instead of to "eat more fruit." That includes my mother's best friend, who lost her leg before she lost her life some years ago now.

The lies go on almost every day in the press and on the daily news or morning show, and people continue to believe them. And until the lie is stopped, we'll have more dead best friends, more dead mothers, more dead sisters, etc... It doesn't have to be this way.
