Time to Revise Dietary Fat Guidelines?
Data presented at the recent European Society of Cardiology Congress has led to a call to revise global guidelines on dietary fat intake, cardiovascular risk, and mortality.
Results of the Prospective Urban-Rural Epidemiology (PURE) study involving more than 135,000 people in 18 countries indicate that high carbohydrate intake is associated with worse total non-heart related mortality and high fat intake is associated with lower mortality.
For the study, researchers analyzed the consumption of carbohydrates, total fat, and types of fat using food frequency questionnaires and assessed links with heart disease and death. During the study period and follow-up, they discovered that people with the highest carbohydrate intake had a 28 percent higher risk of total mortality than those with the lowest carbohydrate intake. Those with the highest total fat intake had a 23 percent lower total mortality risk and an 18 percent lower risk of stroke than those with the lowest total fat intake.
These findings do not support current guidelines, which recommend limiting total fat to less than 30 percent and saturated fat to less than 10 percent of your daily diet.
