Media reports emerged recently claiming that current NHS guidelines on saturated fat were wrong and that sugar and carbohydrates posed the real dangers to health. The articles that were published presented the claims of a cardiovascular research scientist, James DiNicolantonio, and aimed to refocus dietary advice on sugar and away from saturated fat modification and reduction. The Henry Mayhew Foundation's 'True or False?' project looked into the debate and found that the media's presentation of the core issues was short of both context and detail.
The Daily Telegraph reported on 6 March 2014, that DiNicolantonio's research meant current NHS guidelines may be “putting the public at risk”. The Daily Mail made more controversial claims, stating that “research now fails [emphasis added] to show a link between saturated fat intake and risk of cardiovascular disease [with saturated fat actually found to be protective]”.
Saturated fat can ordinarily be found in foods such as butter, cheese, fatty meat, biscuits and cakes. At the moment, public health guidelines advise that a person should limit their intake of saturated fat to around 10% of total daily energy intake. For over half a century, a high saturated fat intake has been associated with an increased risk of coronary heart (and cardiovascular) disease. DiNicolantonio claims that it is actually refined carbohydrates that increase blood cholesterol levels and present a health risk to individuals.
The media reports were based on DiNicolantionio's essay which was published in BMJ Open Heart, a highly respected medical journal. The reports gave the impression that current UK guidelines were misconceived and misguided. In fact, these claims did not mention several studies conducted over the past 50 years which found that foods high in saturated fat raised LDL cholesterol (the “bad cholesterol”) levels of the trial participants.
James DiNicolantonio stood by his claims and told The Henry Mayhew Foundation that “there is no proof that saturated fat from real food is harmful, not a single study”.
