Eat less saturated fat: that has been the take-home message from the U.S. government for the past 30 years. But while Americans have dutifully reduced the percentage of daily calories from saturated fat since 1970, the obesity rate during that time has more than doubled, diabetes has tripled, and heart disease is still the country’s biggest killer. Now a spate of new research, including a meta-analysis of nearly two dozen studies, suggests a reason why: investigators may have picked the wrong culprit. Processed carbohydrates, which many Americans eat today in place of fat, may increase the risk of obesity, diabetes and heart disease more than fat does—a finding that has serious implications for new dietary guidelines expected this year.
In March the American Journal of Clinical Nutrition published a meta-analysis—which combines data from several studies—that compared the reported daily food intake of nearly 350,000 people against their risk of developing cardiovascular disease over a period of five to 23 years. The analysis, overseen by Ronald M. Krauss, director of atherosclerosis research at the Children’s Hospital Oakland Research Institute, found no association between the amount of saturated fat consumed and the risk of heart disease.
The finding joins other conclusions of the past few years that run counter to the conventional wisdom that saturated fat is bad for the heart because it increases total cholesterol levels. That idea is “based in large measure on extrapolations, which are not supported by the data,” Krauss says.
One problem with the old logic is that “total cholesterol is not a great predictor of risk,” says Meir Stampfer, a professor of nutrition and epidemiology at the Harvard School of Public Health. Although saturated fat boosts blood levels of “bad” LDL cholesterol, it also increases “good” HDL cholesterol. In 2008 Stampfer co-authored a study in the New England Journal of Medicine that followed 322 moderately obese individuals for two years as they adopted one of three diets: a low-fat, calorie-restricted diet based on American Heart Association guidelines; a Mediterranean, restricted-calorie diet rich in vegetables and low in red meat; and a low-carbohydrate, nonrestricted-calorie diet. Although the subjects on the low-carb diet ate the most saturated fat, they ended up with the healthiest ratio of HDL to LDL cholesterol and lost twice as much weight as their low-fat-eating counterparts.
Stampfer’s findings do not merely suggest that saturated fats are not so bad; they indicate that carbohydrates could be worse. A 1997 study he co-authored in the Journal of the American Medical Association evaluated 65,000 women and found that the quintile of women who ate the most easily digestible and readily absorbed carbohydrates—that is, those with the highest glycemic index—were 47 percent more likely to acquire type 2 diabetes than those in the quintile with the lowest average glycemic-index score. (The amount of fat the women ate did not affect diabetes risk.) And a 2007 Dutch study of 15,000 women published in the Journal of the American College of Cardiology found that women who were overweight and in the quartile that consumed meals with the highest average glycemic load, a metric that incorporates portion size, were 79 percent more likely to develop coronary vascular disease than overweight women in the lowest quartile. These trends may be explained in part by the yo-yo effects that high glycemic-index carbohydrates have on blood glucose, which can stimulate fat production and inflammation, increase overall caloric intake and lower insulin sensitivity, says David Ludwig, director of the obesity program at Children’s Hospital Boston.
Will the more recent thinking on fats and carbs be reflected in the 2010 federal Dietary Guidelines for Americans, updated once every five years? It depends on the strength of the evidence, explains Robert C. Post, deputy director of the U.S. Department of Agriculture’s Center for Nutrition Policy and Promotion. Findings that “have less support are put on the list of things to do with regard to more research.” Right now, Post explains, the agency’s main message to Americans is to limit overall calorie intake, irrespective of the source. “We’re finding that messages to consumers need to be short and simple and to the point,” he says. Another issue facing regulatory agencies, notes Harvard’s Stampfer, is that “the sugared beverage industry is lobbying very hard and trying to cast doubt on all these studies.”

Reply | Report Abuse | Link to thisThe more I hear the more Frank Zappa seems apropos: "Everything you know is wrong."
Many studies, by reputable scientists and organizations since the 1980's strongly support these conclusions. AS often happens these results did not meld with the invested interests of the time, and were therefore disparaged and ignored. AS is often the case money and prestige were considered more important than scintific fact. Refer to "GOOD CALORIES, BAD CALORIES" by Gary Taubes for a well documented tale of the journey of 'fats, carbs, and the controversial science of dies and health' If you actually read this book you will be astonished at the truths that are revealed and DOCUMENTED.

Reply | Report Abuse | Link to thisWhat's interesting to me is that the USDA's nutrition recommendations first demonized saturated fats in the 1970s, and many analyses have indicated that this led to our current national proclivity to think of carbohydrates as "guilt-free" as long as the foods consumed contain little or not fat. It seems therefore that we only have these data about refined carbohydrates because of what may have been a mistaken analysis of the role of lipids in human health.

How are carbs not synonymous with sugar?
Reply | Report Abuse | Link to thisActually, all carbohydrates turn into glucose in the body, complex, refined, or sugar. The issue is how fast these carbohydrates turn into glucose and affect th insulin levels in the bloodstream. The more refined the carb and/or the higher the glycemic load of the food, the worse it is for you. Pasta, sugar, rice, potatoes all of these are bad carbs. Brown rice is a bit better, but still has quite an affect on the insulin reponse when eaten. I suggest you read through Gary Taubes' Good Calories, Bad Calories book for a great, in depth look at the science behind low-carb/low-GL diets.
Reply | Report Abuse | Link to thisWell it's interesting to know indeed (and I congratulate with the authors) ,however I often think there seems to be as a recurrent theme in those studies (their design I mean..) a kind of "stigmatisation" (ie the bad substance/molecule etc.) implying on the other side stays the "good molecule" (in this case fats,so contradicting previous studies..).Having a MD background,I often read in medical journals bulletins etc. of the so called "worldwide obesity epidemic ",so my point is wouldn'it be better to design those studies about nutrition on "quantity rather than "quality" (ie discussing as usual which foodstuff is healthier)......?After all the target should be from a public-health perspective,to see less obese people around,while of course being able to mantain a" modern-services-society" as we have today-western standards I mean..- ..( Simply finding a behavioral trick may help solving this issue,eg wear a warmer shirt instead of drinking 4 colas in a row....)

One interesting point is that the New England Journal of Medicine study had people on the low carb diet eating mostly vegetarian sources of protein. I suspect that this would result in reduced calories compared to a standard low carb diet, and I'm really curious what the results would have looked like had the low carbers feasted on cheeseburgers and bacon for the study.
Reply | Report Abuse | Link to thisI tried low carb dieting once but took the common approach of eating a ton of meat and dairy and not much 'healthy'. I didn't really lose any weight. However, years later when I developed gallstones, I was forced onto an extremely low fat diet (eating fat would cause excruciating pain) and I lost around 25lbs in less than 2 months. But of course, a lot of this was calorie restriction (when you can't eat anything with more than a gram of fat in it, your options are limited and foods that you would wolf down are off the table).
I suspect the approach used by their low carb dieters (vegetarian proteins and fats with heavily restricted refined carbohydrates) is a great way to go. By eating beans and protein laden grains you'll get fewer calories than you would by eating bunless bacon cheeseburgers, and more whole grains and vitamins to boot, all while avoiding the damaging effects of refined flour and sugar.
The NEJM study recommended vegetarian sources of fat/protein due to religious and cultural factors. The study was done in Israel as I recall. I believe that the conductor of the study later stated that the recommendation had little bearing on the outcome of the study. Instead of butter + meat, it was likely olive oil + meat. No dairy and meat at the same time!
Reply | Report Abuse | Link to thisTo the contrary, gnarfle, beans and grains have lectins and a lot of carbohydrate, making them very unhealthy foods. Moreover, we evolved eating animal proteins. While we are listing anecdotes, the more I have relied on foods of animal origin, the healthier I have become. It's not about calories, it's about insulin.

The 4 girls listened attentively to everything they heard, ate less red meet, more salads, more veggies and grains and forcefully advocated their positions to everyone around them, to our great annoyance. The four boys did whatever pleased them, including eating generousness amounts of steak, eggs, bacon and ice cream. Surely other factors may be at work, but today the four girls, once cute and slim up to their pre-teens (before they became 'educated'), are now all obese and struggling with various physical ailments.

I conclude that the message of a balanced diet (the message that my parents generation was fed), was more wise then the incomplete scientific messages that my generation was fed.
Since eliminating potatoes and bread from my diet, I have lost weight and have never felt healthier. I have also eliminated all dessert except ice cream. There is no doubt in my mind that moderate carb intake is good.

Reply | Report Abuse | Link to thisActually, it isn't all about "balanced diet". The culprit here is a single villain -- fructose. Not "high fructose corn syrup", though it is a problem, but fructose itself. It's not a nutritive substance. It's outright toxic. NO part of the human body uses it. The liver has to eliminate it exactly as it would a poison, and the waste products generate FAT, just like alcohol. Half of sucrose is fructose. The only reason fruit gets any kind of a pass is because of the fiber it contains, which helps slow the absorption.

Reply | Report Abuse | Link to thisUnfortunately Pure Science is no longer pure. We must be SKEPTICAL of all reported research results, and must ask ourselves one question first. "Who Paid for the Research"? In most funded research there is a vested interest that is looking for specific results that will support their position. Often if the results are not the desired one, the research gets buried.Ask who did the research; was it a noted and respected facility like the Tufts University School of Nutrition, or 'Ralph and Charley's auto body shop and research as you like it"?

There is not a lot of huge obscene profit in fresh unbranded fruits and vegetables, meat and dairy products. The real bux lies in the $4 bag of salty sugary snacks with a manufacturing cost of about 8 cents. Ready made, prepared foods, highly processed, for convenience, tasty and loaded with additives is where the profits lie.
Consider the misinformation around global warming issues. Currently we really do not know who to trust and who to believe.
It is not difficult to discover who has paid for and supported research that is published.

That is the difference between science and religion. In science the process remains constant but the answers change based on the evidence. In religion the answers remain constant, it is the process that is changed to create the favoured result.

If either or both are wrong, or if it is more complicated than that, then new studies need to be performed than can account for multiple hypotheses.

Reply | Report Abuse | Link to thisAny carbohydrate that turns into glucose is dangerous. The whole point is that glucose (carbs) drive insulin up, which drives up fat storage. The more carbs you eat - even if it's all "healthy' carbs like fruit - the more likely you are to get heart disease and diabetes.

In the last 8 months I've dropped almost 90 pounds, gotten my diabetes completely under control, eliminated my arthritis (which turned out to be a wheat allergy) and migraines (a gluten allergy) and IBS (both wheat and gluten allergy reaction). I no longer have to use a wheelchair. I can walk two miles and not hurt during or afterwards.
Eliminate everything processed and stick to the edges of the store when you shop. Eat a good ribeye at least twice a week. Eat butter. Eat high-fat beef.

You'll live longer, you'll be healthier, and you'll feel fantastic.

Two problems with this story. One, the amount of fat consumed has been going up along with obesity, even though the percentage of fat has been declining. We're eating more of everything, so it's ridiculous to say we're eating less fat and are getting obese. Simply not true. This is a canard trumpeted over and over on the internet by the low carb crowd, and it's depressing to see Scientific American parrot the same faulty logic here.

I actually can't believe some of the regulations in place regarding the recommended carbohydrate intake that are in use in the schools in the US, where the kids get French fries (which is considered to be a vegetable serving, while technically even raw potatoes are not vegetables) as a side to a burger with a bun, plus an additional piece of bread. Where is the real good food in this lunch? It is that apple that every kid throws away as they leave the dining room... This is very sad and we all - it comes from each individual - need to start making the change - you don't have to wait for the official guidelines to know what's right and what makes sense. Teach your kids to make good choices and practice what you preach. Is it having a donut or having a banana for a snack, even though the glycemic index might be the same for both? You know which one is the right answer. It's your choice - and your life.

But the real suggestion is to eliminate gluten grains, refined grains, sugar (especially fructose), vegetable oil (especially hydrogenated veg. oil = bad saturated fat) and replace them with animal fats (good saturated fat), animal meat and organs, some vegetables and fruit. There's no need to obsess over macro-nutrients if we simply follow the example of our paleolithic ancestors and many recent, non-industrialized cultures, who did not suffer from the diseases of civilization. So go ahead and gorge on butter (especially pastured butter), just skip the toast.

The notion that a class of diseases are associated with civilization has been around for more than a century, and the leading culprits implicated in this hypothesis are refined-carbohydrates. The most recent advocate for this viewpoint is science writer Gary Taubes, and he makes a formidable case in his book Good Calories, Bad Calories. As far as I've been able to determine, his description of fat regulation is accurate. In contrast, this key physiological mechanism is often seen as being completely irrelevant for practitioners of the conventional view. That should tell us something!

Reply | Report Abuse | Link to thisThe incidence of diabetes and obesity is more closely related to cellulose intake in the diet. This would be in any form of plant roughage like celery, apples, carrots, etc. The fact is, bacteria turn the cellulose into energy and produce BUTYRATE which causes major changes in mitochondria by way of gene regulation. In mice, the feeding of butyrate reversed obesity by way of genetic upregulation of insulin sensitivity. Butyrate reversed diabetes. This modulation occurs because with healthier mitochondria (redox status) they can acually process more carbohydrate for ATP production. Insulin resistance is a method to preserve life in the cell instead of apoptosis through mitochondrial degredation. The study was published in "Diabetes" July 2009. Another study in "The Journal of Clinical Investigation" March 09, directly links the H2O2 production of redox deprived mitochondria to inflammation and insulin resistance in rodents and humans. The key dietary factor is antioxidants, which results in robust mitochondria and this is also key in brain degeneration with aging. Veggies are full of antioxidants. And they clean your teeth. :-)

Reply | Report Abuse | Link to thisWith that ever wonderful concept of hindsight, it's not at all surprising, in fact.
The first vertebrate and non-vertebrate forms of life had nothing else to feed on but vegetation - the herbivores. So obviously they evolved with a toleration of the carbohydrate content of plant matter, its intake not causing harm to their health - evolution is not perverse in any way. This carbohydrate intake was converted into the most suitable organic compounds which can be stored to provide energy on demand, which we refer to as animal fats. This was a very clever evolutionary "discovery".
Once the herbivores had multiplied to vast numbers, carnivores next appeared on the scene. And that clearly includes our own species, homo sapiens, and all our antecedent species, through their evolutionary stages.
Although the fatty components of animals, whether herbivores or carnivores, do have different compositions, they are mostly similar in their organic makeup, if for no other reason than the very simplest one, namely that organic chemistry unequivocally dictates that only a relatively small variety of biochemicals will work properly in a biological sense to store energy in a chemical form which is readily accessible to the animal. Therefore is it likely that carnivores would have evolved in a way that eating the fat of its victims would cause harm to their health? Of course not, otherwise such an animal species would have never been able to evolve, its precursors rapidly becoming extinct.
It has only been over the past 150 years or thereabouts that mankind has used its technological capabilities to grow plants for their sugar content, and refine cereal foods, such as bread, etc, largely into their carbohydrate content, which includes cellulose. Thus has the food intake of modern man dramatically changed through its modern technological capabilities, bypassing all the safeguards which evolution had incorporated into the biological makeup of mankind, and all other carnivores, to be able to tolerate an intake of animal fats without harm to their health.
So, why should we be surprised, now, at the fact that carbohydrates and sugars can be harmful?

Dr. Atkins has been saying and writing about this for years. Nothing new here. Remember there are 2 (two) Atkins diets: the first one to lose weight and then the second, Atkins Maintenance Diet which is one you stay on for the rest of your life.

Its mind boggling to me that the low-fat myth has lasted as long as it has. Back in 1972 when Dr Atkins published his first book he pointed out the folly of the concept. According to the entrenched science, the diet should produce the opposite results from what it does. That it works on anyone is proof that the existing models are deeply flawed and yet the studies on the subject have been few and all the while the mainstream view of medicine has been to recommend a damaging diet.

Until then, don't let cookie cutter advice thwart your existence.

Reply | Report Abuse | Link to thisThe problem has been that the biochemistry of fat regulation has not been at all considered in the case of obesity and its attendant "diseases of civilization". As "low-carb" gets more attention, more people will want to know why, and this is where one can describe how the human body works in the typical case. There are of course variations in the population to insulin sensitivity, or other hormone problems, but the important thing is that the scientific community agrees and evangelizes the science behind fat regulation.
It also highlights the importance of understanding the science before making government recommendations or regulations. Care to estimate how many billions of dollars have been lost because of this fiasco? How many lives lost, or quality of life seriously diminished because of this nonsense? It's one of our greatest tragedies.
Dr. Adkins put this together in 1972:
Reply | Report Abuse | Link to this"The Atkins diet, officially called the Atkins Nutritional Approach, is a low-carbohydrate diet created by Robert Atkins from a research paper he read in the Journal of the American Medical Association published by Gordon Azar and Walter Lyons Bloom. Atkins stated that he used the study to resolve his own overweight condition. He later popularized it in a series of books, starting with Dr. Atkins' Diet Revolution in 1972. In his second book, Dr. Atkins' New Diet Revolution, he modified or changed parts of the diet but did not alter the original concepts."
Science has been catching up with his insights since then. Congratulations.
No real news here. Proponents of a paleolithic diet have long held that carbs have little to no place in the diet we evolved to eat. The so-called "balanced diet" as portrayed in government food pyramid propaganda is heavily grain-based, but go out into a forest and try to pick yourself some grains and then make bread or pasta. These things are the product of recent industrialized agriculture, and are unlike anything we have the evolutionary adaptations to cope with. Bread, pasta, cereals are as much a part of a natural "balanced diet" for humans as sticks and stones.

Reply | Report Abuse | Link to thisFirst off, this was a "meta-analysis" of several studies that mainly relied on food frequency questionnaires in the form of "in the past 12 months, how often did you consume x?" These are notoriously unreliable.
Reply | Report Abuse | Link to thisSecond, the category of "refined carbohydrates" encompasses a great deal. White pasta, for example, has a fairly low glycemic index, somewhat comparable to whole wheat pasta. Brown rice is still fairly high GI. Lumping the "refined" carbohydrate foods all into one category is troublesome.
Second, a recent study (that also used troublesome food frequency surveys) showed that the intake of simple carbohydrates only shows an effect in women: http://www.usatoday.com/news/health/2010-04-16-carbs-women_N.htm
The meta-analysis they refer to that found that saturated fat has no effect on heart disease rates was performed by a man who has ties to the dairy industry. Given that this finding goes against the vast majority of the information we have and is just a meta-analysis (a study of studies), I'd take this information with a grain of salt.
Last, the majority of the low-carbohydrate info that is spreading out there is based upon flawed principles. The idea is that carbs cause the body to overproduce insulin, a hormone that provokes hunger pangs, which leads to more eating. As insulin induces body cells to store excess carbs as fat, the pounds pack on. So cut the carbs, insulin levels stay low, and less fat is stored.
In actual fact, proteins and fats both stimulate insulin production. Any excess of carbs or proteins or fats is stored as fat. That excess fat, whatever its origins, cranks out bioactive molecules (such as interleukin-6 and leptin).
These molecules promote damage to the internal lining of arteries, which fosters atherosclerosis. This is why the obese face higher CHD risks.
This means an excess of proteins or fats is as bad as an excess of carbs, and vice versa.
This article quotes a 2008 study showing that Atkins dieters "lost twice as much weight" as those on conventional low-fat diets.
It has now been consistently shown in many studies that Atkins does not outperform other diets in the long run. Several rigorous studies have found greater weight loss through Atkins than conventional diets in the first six months, but no significant weight difference over 12 months.
Studies do show that Atkins lowers one's triglycerides, fats also involved in CHD, and that it raises (good) HDL cholesterol. Critically, however, Atkins raises (bad) LDL cholesterol.
In fact, bad cholesterol typically decreases with weight loss in all diets - except low-carb ones. This is probably because of the extremely high intake of saturated fats through unlimited meat consumption permitted in Atkins.
It is now established that, when it is starved of carbs, the body overproduces methylglyoxal, a chemical that causes blood vessel and tissue damage. Heart rhythm problems have also been noted.
So is Atkins safe over the long run? Recently, two huge European studies that had followed dieters over a decade were published. In both studies, people who had been on low-carb, high-protein diets for years faced significantly higher risks of dying from CHD.
More deaths from cancer were also noted in one of the two studies. Intake of too little grain, fruit and vegetables for years may have led to a higher incidence of cancer.
You only need to remember one thing. It is not about calories. It is about imflamatory insulin! An insulin response makes you hungry , FAT and prone to all dseases of modern civilization! The Banting Diet was invented hundreds of years ago -a low carb diet- and guess what it still works!

Although this article states that refined carbs have been found in the presented studies to be worse for your heart than saturated fat this does not mean that saturated fat is suddenly 'good' for you and now you can eat as much saturated fat as you want. Yes, reduce REFINED carbs (which isn't new information - only its application to the heart vs saturated fat is) but don't make the mistake of allowing yourself free reign on saturated fats as a result of this article.

Reply | Report Abuse | Link to thisBelow is a section from the statement released by the European Heart Network in regards to their opinion of this meta-analysis, titled “European Heart Network position piece: Impact of saturated fat on cardiovascular disease obscured by over‐adjustment in recent meta‐analysis”
“However, the meta‐analysis (and an accompanying opinion piece by the same authors (4)) is compromised by a number of serious flaws and omissions.”
“The most serious of these flaws is an over‐adjustment for serum cholesterol levels.”
“Adjustment for serum cholesterol levels will inevitably bias the results of the meta-analyses towards finding no association between dietary saturated fat intake and cardiovascular disease, but the authors do not mention this limitation in their article.”
“As Jeremiah Stamler asserts in his editorial, what was actually found by the meta-analysis was ‘a statistically non-significant relation of SFA [saturated fat] to CHD... independent of other dietary lipids, serum lipids, and other covariates’. A more appropriate and informative analysis would have included non-adjusted associations between saturated fat and cardiovascular disease. An examination of the forest plots provided in the article shows that those cohort studies that did not adjust for serum cholesterol levels were more likely to find a positive association between saturated fat intake and cardiovascular disease, suggesting that a meta-analysis of unadjusted data would likely produce positive results.”

For those that think vegetarianism is somehow more "moral" than other food - newsflash, ultimately, EVERYTHING eats EVERYTHING else via the natural processes taking place of dead organic matter being turned into soil. That lovely pear tree literally thrives on soil made by dead matter. BTW - founder of the much-lauded Mediterranean Diet died of heart failure at age 71 this year . . ..media very quiet about the whole thing
Reply | Report Abuse | Link to this...and from where have you attained these long-held beliefs? I will answer that for you: Mainstream advertisers of products that they want to sell to the consumer. There have always been, and always will be, huge corporations looking out for their bottom line by lobbying very hard to skew the scientific evidence in their favor, and they have been very successful.
Reply | Report Abuse | Link to thisWow I am amazed at the weird ideas & mythical hogwash. all evidence points to us being vegetarians for the most part. considering how our bodies digestive system is designed. so we are mildly omnivores out of necessity.
Reply | Report Abuse | Link to thiseven if you go by the evolution idea if you check for yourself books on physical evidence the earth was one time a tropical to semi tropical place from pole to pole. not what is shown books and tv, man didn't run around living in caves with fur dresses eating mostly meat living among the cold and snow. that is a hollywood movie.
man was always a man, unless you can prove via physical evidence of manape fossils man was always a man. so concluding diets based on that is insane. basing one's health on myth is dangerous. man subsisted on plant material until up to the global flood. meat had to be allowed as now there would be growing seasons that were limited. before growing season was all year.
I won't argue evolution/creation thing, because that is a red herring on the subject. you should be able to find info enough to see for yourself. you have libraries internet etc. over processing of food is the problem. stripping all the nutrients is a bad idea, but it allows a long shelf life and is good for corporations bottomline. I suggest articles such as the obesity epdiemic is metabolic syndrome a nutritional defiency?
also check out ultrametabolism by dr hymen, he has a website. also check out how to be naturally thin by eating more. by jean antenello, by the way someone said fructose is poison? the liver is only organ with enzymes to metabolise it to glucose for it's own use. not to eliminate it like a toxin. this allows it to avoid competition for glucose for its own stores.
it has to store enough to keep your brain going while you fast otherwise you suffer hypoglycemia. why dont people research how their bodies work? that way they won't make unintelligent remarks. if I can learn it then so can everyone else. I am just an average common man. I hope I didn't seem to harsh. the info is there if we are interested enought to look for it.
I explained long ago why calories from Carbs not used for energy are converted and stored as saturated and monounsaturated fatty acids. According to my research, the most significant factor in cardiovascular disease is abnormal levels of the essential fats.

Read my articles and letters in Metabolism, Am. J. of Clinical Nutrition and others for a scientific explanation, the flaws of the USDA food pyramid (an exchange of letters with the USDA).
There are commercial and scientific interests as well as pressure from consumers to make, sell and eat less healthy foods. Perhaps we should allow people to purchase and pay for health insurance to cover the expenses they want.
Dr Doug Mcguff speaks about the research behind this topic in layman terms, you should check his book out 'Body By Science' :)
Reply | Report Abuse | Link to thisYou claim, nobody is advocating eating saturated fats, just shows how ignorant you are, it is absurd. Inuits who consume nothing but red meat and seal blubber are among the healthiest in the world! THE researcher who discoverd the ills of trans fats decades ago totally disagrees. http://www.eatfatlosefat.com/

Reply | Report Abuse | Link to thisNo, you're wrong. Dr. Robert Atkins died in New York of head trauma after he slipped and fell on ice outside his home. You can google this and find it easily in all the news report. Agenda much?

Reply | Report Abuse | Link to thisThere are at least 101 scientific studies that show that saturated fat and cholesterol prevent heart disease. You can find out what they are by reading the book "Saturated Fat and cholesterol Prevent Heart disease: The evidence from 101 scientific studies" by David Evans. So saturated fat is, in fact good for you. It is only when it is combined with a lot of carbs, especially refined ones, that is may (may) cause problems. Humans have been eating saturated fat for most of their existence and there are populations today that rely on saturated fat from coconuts. It is not harmful.
Reply | Report Abuse | Link to thisCarbs(fruits,vegs,legumes) are filled with vitamins,minerals,anti cancer & anti heart disease properties.Loaded with(lycopene like watermelon that fights prostate cancer)pectin(a heart disease fighter in apples),flavono,anti oxidants etc.Your brain runs on sugar & your body prefers carbs to run.Thats why in nature natural foods(except animal protein) provide little fat & some protein.Its mostly carbs.Obviously if you eat cake or twinkies theres not much nutrients & it has deadly trans fat.Fibre in carbs absorbs ldl cholesterol & carbs have Vitamin C a powerful ant oxidant that builds collagen a necessary component for coronary cells.The misinformed people here are amazing.Gary taubes has been debunked(see Michael fumento^s Big Fat Lie article where the people Taubes interviwed were taken out of context or did not have data they stated printed by Taubes on purpose since it went against his ideology)The few studies that show saturated fat has no correlation to heart disease had beans as a source of sat. fat(a Israeli study) or didn^t take into account cholesterol lowering stain drugs(very common these days & are also anti inflammatory.Try going 3 months without carbs.Just eat fat & protein see what happens,I dare you all.You can be like the eskimoes eating RAW animal organs to get their Vit C or be quick like them to devour carbs(plants) when thy came across them cause the body hates ketosis(which mimicks a starvation state). Protein is a well stimulator of insulin too,I guess protein is evil.ASP ---acylation stumulating protein,is a hormone that shoves fat into fat cells without insulin raised or carbs present.Thats right, whether its FAT,CARB or PROTEIN your body wil have no problem converting into fat any excess calories that are around.Refined carbs were plentiful in the 60s & 70s(little obesity),in the 80s,however obesity skyrocketed, why ?----heres the secret,you ready ? You eat too much & do too little in activity. Surprise ! Surprise ! People were takin in 400-500 xtra calories a day & with technology leading the way,were less active
