The article published in the BMJ’s Open Heart journal argues that dietary guidelines adopted by British authorities in the early 1980s and still in use today are based on “very limited evidence”.
The British Dietetic Association recommend that men should consume no more than 30g of saturated fat daily while women are advised to consume no more than 20g.
High levels of saturated fats are found in fatty red meats, biscuits and cakes as well as dairy products including butter, cheese and cream.
The reports authors, led by University of the West of Scotland researcher Zoë Harcombe, claim that an analysis of the original evidence used to justify saturated fat warnings has exposed serious flaws in how the original data was gathered.
