In the guardian today is a very extensive and detailed article asking whether headlines like "butter is back" should be heeded. The article can be read at theguardian.com/lifeandstyl...
The article is written with a powerful sub-title, "This is not just bad science – it will cost lives, say experts." It goes on to make the case for the overwhelming evidence that butter & cholesterol deniers seek to suggest is bad. To do this it cites Public Health England, the World Health Organization, the British Heart Foundation (BHF), Heart UK as all organisations who think butter and cholesterol intake should be severely limited.
So why now? Because more than 170 academics signed a letter accusing the British Journal of Sports Medicine of bias. This bias is that they have contributed to the headlines about "butter being good for you" but have continually blocked responses putting the other side of the argument.
At least on this forum whoever joins the debate, from whatever side or angle, has an equal opportunity to express their opinion.
