A global study of people living on five continents has found a diet high in poor quality carbohydrates leads to a higher risk of heart attacks, strokes, and death.

The higher risks of a diet high in poor quality carbohydrates, called a high glycemic diet, were similar whether people had previous cardiovascular disease or not.

Those people consuming a diet in the highest 20 per cent of glycemic index were 50 per cent more likely to have a cardiovascular attack, stroke, or death if they had a pre-existing heart condition, or 20 per cent more likely to have an event if they did not have a pre-existing condition.

These risks were also higher among those people who were obese.

"PURE study papers have already indicated that not all carbohydrates foods are the same. Diets high in poor quality carbohydrates are associated with reduced longevity, while diets rich in high quality carbohydrates such as fruit, vegetables and legumes have beneficial effects," he said.

PHRI research investigator Mahshid Dehghan added: "This study also makes it clear that among a diverse population, a diet low in both its glycemic index and load has a lower risk of cardiovascular disease and death."

Most fruits, vegetables, beans, and intact whole grains have a low glycemic index, while white bread, rice, and potatoes have a high glycemic index.
