And current dietary advice to replace saturated fats with carbohydrates or omega 6-rich polyunsaturated fats is based on flawed and incomplete data from the 1950s, argues the author. Dietary guidelines should be urgently reviewed and the vilification of saturated fats stopped to save lives, he insists.

The meta-analysis published in the journal Annals of Internal Medicine, pooled together the results of 72 previous studies into heart disease and fatty acid consumption. In all the data involved more than 600,000 people in 18 nations.
The Cambridge University researchers led by Dr Rajiv Chowdhury found that whether measured in the diet or in the bloodstream as a biomarker, the scientific evidence does not support guidelines that restrict the consumption of saturated fats in order to prevent heart disease.

The researchers say they also found insufficient support for guidelines which advocate the high consumption of polyunsaturated fats (such as omega-3 and omega-6) to reduce the risk of coronary disease.
Furthermore, when specific fatty acid subtypes (such …
