<p>Nutrition experts have egg on their faces. For years, public health
policy has been to discourage consumption of saturated fat--or most any
fat at all.</p>
<p>The <a href="http://www.ncbi.nlm.nih.gov/pubmed/14998608">diet-heart hypothesis</a>
got its start in the 1950s. Ancel Keys, PhD, and his colleagues
collected epidemiological data from around the world and decided that
they showed a connection between saturated fat consumption and high
blood cholesterol, and consequently, an elevated risk of heart disease.</p>
<p>The <a href="http://www.cdc.gov/cholesterol/cholesterol_education_month.htm">National Cholesterol Education Program</a>, the <a href="http://www.heart.org/HEARTORG/GettingHealthy/NutritionCenter/HealthyEating/The-American-Heart-Associations-Diet-and-Lifestyle-Recommendations_UCM_305855_Article.jsp">American Heart Association</a>
and many other public health organizations promoted the idea that
eating a low-fat high-carb diet would reduce heart disease. A
meta-analysis involving 72 studies and over 600,000 participants now
contradicts that traditional wisdom. The researchers found no link
between saturated fat consumption and a higher risk of heart attacks and
other cardiovascular complications (<a href="http://annals.org/article.aspx?articleid=1846638"><em>Annals of Internal Medicine</em>, March 18, 2014</a>).</p>
<p>Dietitians had told people to use <a href="https://blogs.commons.georgetown.edu/gufoodstudies/2013/06/13/good-fats-and-better-fats-revising-the-diet-heart-hypothesis/">margarine instead of butter</a>
and polyunsaturated fats found in corn or safflower oil because they
were supposed to lower cholesterol and be heart healthy. The new
analysis found no cardiac benefit from such omega-6 rich fats.
Trans-fatty acids like those found in shortening and margarine up until a
few years ago were associated in the analysis with a higher incidence
of heart disease.</p>
<p>This is not the first study to suggest the conventional sat-fat
wisdom might be wrong. The Sydney Diet Heart Study was conducted in
Sydney, Australia, at the height of the diet-heart hypothesis, between
1966 and 1973. In this research, the scientists recruited 458 men who
had recently had a heart attack and were therefore at high risk for a
second cardiac event. The men were divided into two groups: half
continued with their usual diet, while the other group was given
safflower oil and margarine made from safflower oil and told to use it
instead of butter or animal fats. The hypothesis, of course, was that
the polyunsaturated safflower oil would protect the men from a second
heart attack, but the scientists ran out of research money and the data
were not fully analyzed until a research team resurrected them last year
<a href="http://www.bmj.com/content/346/bmj.e8707">(<em>BMJ</em>, online, Feb. 5, 2013</a>).</p>
<p>The data showed that the men given safflower oil did have lower
cholesterol, but they were also 60 percent more likely to die during the
study, especially from heart disease. Of those getting the
safflower-supplemented diets, 16.3 percent died of heart attacks
compared to 10.1 percent of those eating their usual diets with butter
and lard.</p>
<p>Too many of the dietary recommendations of the past half century were
based on belief rather than data. From the evils of eggs to the sins of
sodium, simple public health messages have been shown time and again to
be misleading.</p>
<p>So what guidelines should you use to follow a healthful diet? We
think the grandmothers got it right: real foods, lovingly prepared. It
does take a little longer to cook from scratch rather than eating out of
a package, but the taste and health benefits are big. To learn more
