The Lancet study of 135,000 adults found those who cut back on fats had far shorter lives than those enjoying plenty of butter, cheese and meats. In fact, low-fat diets could raise the risk of early death by almost one quarter.
But the latest research, presented at the European Society of Cardiology Congress, in Barcelona found those with low intake of saturated fat raised chances of early death by 13 per cent compared to those eating plenty.
Consuming high levels of all fats cut mortality by up to 23 per cent.
Researcher Dr Andrew Mente, from McMaster University, said: “Our data suggests that low fat diets put populations at increased risk for cardiovascular disease.
“Loosening the restriction on total fat and saturated fat and imposing limits on carbohydrates when high to reduce intake to moderate levels would be optimal.”
Lead researcher Dr Mahshid Dehghan, said: "A high carbohydrate diet - greater than 60 per cent of energy - is associated with higher risk of mortality.
“Higher intake of fats, including saturated fats, are associated with lower risk of mortality.”
But diet had little impact on heart death risk, suggesting it had a greater impact on other killers such as cancer, dementia, and respiratory disease.
Consultant cardiologist Dr Aseem Malhotra said it was time “for a complete U-turn” in Britain’s approach to diet, and demonisation of fat.
“The sooner we do that the sooner we reverse the epidemic in obesity and diabetes and the sooner start improving health.”
