Mættet fedt og salt bør stadig begrænses

 

Skrevet af Tobias Schmidt Hansen og Maria Felding

I forrige uge udtalte en kardiolog og professor of Medicine at McMaster University, Salim Yusuf, i et foredrag (der efterfølgende er blevet fjernet), at han “dog uden at være ekspert i ernæring” bl.a. mener, at sundhedsorganisationerne tager fejl om, at mættet fedt og salt øger risikoen for hjertekarsygdom. I stedet konkluderer han, at et kulhydratindtag over 50E% er skadeligt, at mættet fedt ikke er skadeligt, og at det ikke gør nogen forskel i sygdomsrisiko at spise grøntsager, frugt eller bælgfrugter. Udtalelser han baserer på sit eget endnu-ikke-publicerede observationsstudie.


Hvorfor Yusuf mener, det er relevant eller ligefrem ansvarligt, at han i sin højtstående position står frem og udtaler dette, kan undre. Ikke alene går det imod årtiers forskning, men det er også baseret på et observationsstudie, der endnu ikke er offentliggjort. Er det virkelig i befolkningens interesse at skabe mere forvirring?

Her er hvad de reelle eksperter har at sige om hans udtalelser:

DAVID L. KATZ, PRESIDENT OF THE AMERICAN COLLEGE OF LIFESTYLE MEDICINE:
“Bizarre and misguided”
“We have no business seeking expert nutrition guidance from non-experts.”

JOEL KAHN, MD:
“Dr. Yusuf began the talk with apparent humility saying “I am not a nutrition scientist” and a few minutes later he proved how right he was.”
“Why did Dr. Yusuf stoop to perhaps the lowest level of his long career by slinging mud at dead and retired colleagues? In a bizarre twist in his presentation in Zurich, Yusuf fawns over the work of journalist Nina Teicholz and it is possible he simply adopted views from her writings without fact checking them. However she is a journalist and he is a world famous physician and, while she can and should be ignored, his actions cannot.

KIM WILLIAMS, MD, FORMER PRESIDENT OF THE AMERICAN COLLEGE OF CARDIOLOGY AND CHIEF OF CARDIOLOGY AT RUSH UNIVERSITY:
“..the PURE study (Yusufs ikke-publicerede studie) had the highest category as >4 servings of vegetables and that was only a small fraction of the population (9,000 out of 150,000). But a recent meta-analysis of prospective trials with over 1,000,000 total subjects demonstrated that consuming 10 servings (800 grams per day) has a dramatic reduction in mortality, stroke, and cardiovascular outcomes.
“In other words, if you want to show improvement with vegetables, it may be best to study vegetarian versus non-vegetarian populations, rather than smaller variations among omnivorous populations.”

*MARION NESTLE, PHD, MPH, OF NEW YORK UNIVERSITY IN NEW YORK CITY:
Yusuf’s “comments are premature and not helpful.”
“In general, it is well established that healthy diets based largely on plant foods are associated with a lower risk of chronic disease.”
