The Truth About Fat

National dietary guidelines were introduced in 1977 and 1983, by the United States (US) and United Kingdom (UK) governments respectively. The two specific guidelines introduced were for people to consume no more than 30% of total calories as dietary fat and no more than 10% of calories as saturated fat.

It was believed at the time that introducing these guidelines would reduce deaths from heart disease. Incredibly, until now, there has been no review of the evidence upon which these guidelines were based.
