Researchers at McMaster University are challenging the current dietary guidelines that focus on reducing fat intake.
The study has found that contrary to popular belief, a diet that contains a moderate amount of fat is linked to a reduced risk of premature death compared to the much-touted low-fat diet.
Findings from the PURE study of more than 135,000 people in 18 countries suggest that dietary guidelines should focus on reducing carbohydrate consumption
The study's lead author says the healthiest diet would be made up of 50 to 55 per cent carbs and 35 per cent total fat, including both saturated and unsaturated fats.
A second McMaster study found eating three to four servings of fruit, vegetables and legumes per day had a similar benefit in reducing the risk of premature death as eating the currently
recommended five-plus servings.
