Health experts have controversially called for an overhaul of dietary guidelines after a large international study found a diet high in carbohydrate is associated with greater risk of premature death, not a diet high in fat.
A study of more than 13,500 people from 18 countries, published in the respected medical journal The Lancet, found diets high in carbohydrates were associated with a 28 per cent higher risk of death, compared to low carbohydrate diets.
Diets with a high total fat intake were associated with a 23 per cent lower risk of death, compared to low fat.
“Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality, whereas saturated fat had an inverse association with stroke. Global dietary guidelines should be reconsidered in light of these findings,” the authors concluded.
The current guidelines recommend that 50-65 per cent of a person’s daily calories come from carbohydrates, and less than 10 per cent from saturated fats.
The study found the average global diet consisted of at least 60 per cent carbohydrate.
In light of the findings, lead author Dr Mahshid Dehghan at McMaster University, Canada would like the carbohydrate recommendation reduced.
“The current focus on promoting low-fat diets ignores the fact that most people’s diets in low and middle income countries are very high in carbohydrates, which seem to be linked to worse health outcomes,” Dr Dehghan said.
“A certain amount of carbohydrate is necessary to meet energy demands during physical activity and so moderate…
