A big, fat mistake?

When dietary guidelines were issued by the US and UK governments in 1977 and 1983, they were badly supported by evidence, so says a recent publication in the British Journal of Sports Medicine. Guidelines called for total fat and saturated fat to contribute no more than 30% and 10%, respectively, to a person’s total energy intake. According to study authors, while authorities acknowledged at the time that the link between fat consumption and heart problems was unsupported, guidelines were released on the grounds that “it couldn’t hurt.” Study authors draw parallels between the introduction of the fat guidelines and the beginning of the rise in rates of obesity and diabetes. They posit that lowering fat consumption may have been instrumental in the skyrocketing incidence and prevalence rates for diabesity.
