More than 160 scientists have accused a leading medical journal of having a "pro-butter bias".
They claim that the British Journal of Sports Medicine is encouraging people to eat fatty foods based on their editor's personal opinions rather than on solid evidence.
At that time, the magazine affirmed that it had not received refutations that questioned the evidence, however, since then a refutation of 168 scientists arose that was not published until later.
The experts demand the editor-in-chief of The BMJ, which publishes BJSM, investigates the allegations and stops publishing "strange" studies based on unstable evidence.

The row began last year when The BJSM published an opinion piece by doctors arguing controversially that saturated fat does not clog the arteries.
Instead, doctors insisted that carbohydrates are bad for the heart.
After extensive coverage, the official Twitter account of the magazine even called its main author, cardiologist Aseem Malhotra, a "brave iconoclast".
At that time, Dr. Malhorta said: "Despite the popular belief among doctors and the public, the conceptual model of saturated fat in the diet that clogs a pipeline is simply wrong."
He added that levels of so-called "good" cholesterol are a better predictor of a person's risk of heart disease than "bad" cholesterol.
Saturated fat, found in butter and cheese, has been shown to increase bad cholesterol.
"It is time to change the public health message in the prevention and treatment of coronary artery disease so that serum lipids (fats in the blood) are not measured and saturated fats are reduced in the diet," the authors wrote. authors of the study.
However, more than a hundred academics around the world have accused The BJSM of downplaying the evidence against butter due to "editorial bias".
They wrote: "It seems that there is an absence of systems to avoid that the personal opinions held or supported by the editor-in-chief generate irrelevant and / or unbalanced narratives".
Others have described the "evidence" that butter is "simplistic," "confusing," and "deceptive."
Dr. Mike Knapton, of the British Heart Foundation, said: "Decades of research have shown that a diet rich in saturated fats increases the" bad "LDL cholesterol in the blood, which increases the risk of having a heart attack or a stroke".
And David Nunan, from the center of evidence-based medicine at the University of Oxford, who organized the protest, also questioned why a magazine devoted to sports medicine publishes articles on fatty foods.
The BJSM, edited by Professor Karim Khan, has published 10 articles that criticize healthy eating patterns.
"It's like the Journal of Atherosclerosis that publishes an article about knee injuries," Nunan told The Times.
& # 39; It is strange and raises questions about why it is there.
& # 39; The narrative has to do with a diet low in carbohydrates and high in fat. That is a personal position.
Dr. Malhotra refused to respond directly to Mr. Nunan's criticisms.
But he quoted a saying attributed to playwright George Bernard Shaw: "I learned a long time ago, never to fight with a pig.
& # 39; You get dirty, and besides, the pig likes it. & # 39;
