British Heart Foundation researchers, who have scrutinised 72 studies that were collectively participated by 600,000 individuals, revealed that there is no evidence to support existing guidance that says changing the type of fat you eat from “bad” saturated to “healthier” polyunsaturated cuts heart risk.
Lead researcher Dr Rajiv Chowdhury said: "These are interesting results that potentially stimulate new lines of scientific inquiry and encourage careful reappraisal of our current nutritional guidelines."
"Refined carbohydrates, sugar and salt are all potentially harmful for vascular health,"
Prof Jeremy Pearson, the charity's associate medical director, said: "This research is not saying that you can eat as much fat as you like.
"Too much fat is bad for you.
"But, sadly, this analysis suggests there isn't enough evidence to say that a diet rich in polyunsaturated fats but low in saturated fats reduces the risk of cardiovascular disease.
"Alongside taking any necessary medication, the best way to stay heart healthy is to stop smoking, stay active, and ensure our whole diet is healthy - and this means considering not only the fats in our diet but also our intake of salt, sugar and fruit and vegetables."
