Lawmakers question effectiveness of dietary guidelines

Lawmakers on Wednesday asked federal officials whether Americans should trust the government’s dietary guidelines, which inform everything from school lunches to advice from a doctor.

Lawmakers from both parties expressed frustration about how the government recommendations have shifted. A government advisory committee’s recommendations in February, for example, said dietary cholesterol now is “not considered a nutrient of concern for overconsumption” after years of doctors saying that Americans consume too much cholesterol and shouldn’t eat too many eggs.

The New York Times kirjoitti:Are Fats Unhealthy? The Battle Over Dietary Guidelines

Let’s start with saturated fats. The committee concluded that existing reports argue that replacing saturated fats with polyunsaturated fats seems to reduce the risk of cardiovascular events and mortality. It also acknowledges that replacing fats with carbohydrates, which many people seemed to do after fats in general were shunned in previous reports, does not lower risk. The committee therefore concluded that saturated fats should be limited to 10 percent of intake and replaced with polyunsaturated fats such as those from nonhydrogenated vegetable oils.

Ms. Teicholz argues that the committee ignored many important studies that might have altered its recommendation. The biggest is the Women’s Health Initiative Dietary Modification Trial....
There was a reduction in saturated fats, but it did not result in any significant benefits. Ms. Teicholz says that this proves that a reduction in saturated fats does not improve health

Ms. Teicholz also takes exception to the committee’s lack of enthusiasm for a low-carbohydrate diet. It is true that the report chose not to update its stance from 2010, basically arguing that there still isn’t enough long-term evidence to support such a diet over a balanced one. She states that two meta-analyses have found that a low-carbohydrate diet is superior to control diabetes, and that two more have found it’s highly effective for weight loss.

The New Yorker kirjoitti:What the Government’s Dietary Guidelines May Get Wrong

The immensity of the challenge became even more apparent late last month, when Nina Teicholz, writing in the BMJ (formerly the British Medical Journal), published a blistering analysis of the scientific report that serves as the basis for the 2015 guidelines. The report, which was drawn up by the Dietary Guidelines Advisory Committee (D.G.A.C.), a panel of nutrition experts, recommends plenty of low- or non-fat dairy, fruits, vegetables, whole grains, seafood, legumes, and nuts, and minimal red and processed meats, refined grains, and sweetened foods and drinks. But, according to Teicholz, the D.G.A.C. failed to adequately consider two relatively recent findings in nutrition science: first, that eating a low-carbohydrate diet may help control certain health conditions, notably Type 2 diabetes and obesity, and second, that saturated fats may not be as catastrophically unhealthy as previously supposed.

Lei è Nina Teicholz, giornalista, vive a New York e è autrice di The big fat surprise, un libro che ha suscitato interesse, discussioni e molte critiche. Lui è David L.

Heart and Stroke Foundation of Canada Position Statement kirjoitti:
RECOMMENDATIONS

The science of nutrition is ever-evolving with new evidence emerging all the time. It is becoming increasingly clear that what has the most impact on health is the overall quality of one’s diet, combined with the types and quantity of food consumed. The following recommendations do not include a threshold or limit for saturated fat and instead focus on a healthy balanced dietary pattern, which can help Canadians reduce consumption of saturated fats.

Early studies found an association between cardiovascular disease and saturated fat while more recent studies have found no such association. These mixed findings have been the focus of recent scientific debate, and underscore that the health effects of saturated fats are complex.

Nina Teicholz vastaa artikkelinsa kommentoijille....
Nina Teicholz kirjoitti:Thank you to all those who have commented on my article. I will attempt to respond to all points raised, but will particularly respond here to Barbara Millen, chair, 2015 Dietary Guidelines Advisory Committee (DGAC), and Bonnie Liebman, nutrition director of the Center for Science in the Public Interest

http://www.bmj.com/content/351/bmj.h496 ... -responses


Nina Teicholz kirjoitti:Reijo P. Laatikainen correctly comments that, in describing the body of literature that had been overlooked by the DGAs, I omitted a 2014 review paper by Fardet and Boirie, a review of pooled, meta-analyses and systematic reviews on food and health. This review found that plant food groups are associated less with diet-related chronic disease than are animal food groups. Among animal food groups, dairy/milk products, were found to have no association with the risk of diet-related chronic disease, while red/processed meats were associated with higher risk.

However, I did not review any observational findings in my article, because I prioritized the more conclusive clinical trial data, as the DGAC itself did in its reviews.

Nina Teicholtz kirjoitti:This rapid response was also fact-checked and peer-reviewed, as was the original article.

The correction pointed out that if anything, I had understated the degree of evidence in 2012 when the DGA committee started its work. The whole point of the sentence (now corrected) was to show that on the subject of whether saturated fats cause heart disease, committee members had plenty of evidence to compel them to ask the NEL for a systematic review of the literature. But the committee did not ask. Instead, it did its own non-systematic review, which both understated and omitted review papers showing that saturated fats do not increase cardiovascular mortality and questionably cause heart disease at all.

Keskustelu ravitsemussuosituksista senkun kiihtyy Amerikassa...
The Verge kirjoitti:183 scientists sign letter asking BMJ to retract its bogus nutrition investigation

Among the letter's signatories are more than 10 Harvard University scientists, including the chair of Harvard's Department of Nutrition, Walter Willet. Other prominent names included in the letter are Richard Decklebaum, director of the Institute of Human Nutrition at Columbia University; Boyd Swinburn, director of the World Health Organization Collaborating Centre for Obesity Prevention at Deakin University in Melbourne, Australia; and Antonio Gotto, former dean of Weill Cornell Medical College. Together, the letter's 183 signatories state that a retraction should take place "not only to inform your readers, but also to protect the BMJ’s credibility."

The End of Dietary Guidelines for Americans?

United States law mandates that Dietary Guidelines for Americans, containing “nutritional information and guidelines for the general public,” be issued every five years. The 2015–2020 edition of Dietary Guidelines for Americans was recently released, the eighth such set of guidelines published since this process began in 1980. Here’s hoping these are the last such governmental guidelines issued.

Lisää kritiikkiä USAn tunnetulta kardiologilta

New dietary guidelines 'represent a nearly evidence-free zone,' says a leading cardiologist

In a scathing commentary published Tuesday in the Annals of Internal Medicine, one of the country’s leading cardiologists — Dr. Steven Nissen of the Cleveland Clinic — rips apart the supposed scientific rationale for the latest installment of the Dietary Guidelines for Americans, which were released in their finalized form to the public earlier this month.

“A detailed review of the new guidelines confirms a disturbing reality: the nearly complete absence of high-quality randomized, controlled clinical trials (RCTs) studying meaningful clinical outcomes for dietary interventions,” he writes. “The report repeatedly makes recommendations based on observational studies and surrogate end points, failing to distinguish between recommendations based on expert consensus rather than high-quality RCTs.”

"Critics have suggested that the Seven Countries Study was biased in favor of the hypothesis that dietary fat and cholesterol were critical factors in coronary disease. The study examined heart disease rates in Italy, Greece, Yugoslavia, Finland, the Netherlands, Japan, and the United States. Yet data were available for 22 countries. The researchers omitted countries, such France, where consumption of total and saturated fat are very high but the risk for heart disease remains low"

https://www.minnpost.com/second-opinion ... ding-cardi

Dr. Steven Nissen sanoo,että suositukset perustuvat lähinnä seurantatutkimuksiin ja surrogaattipäätelmiin. Ancel Keys saa myös kuulla kunniansa....
