Everyone knows that a diet full of white bread, pasta and rice is bad for your waistline. Now scientists say these types of refined carbs could also impact your mind - putting post-menopausal women at higher risk for depression.
In a new study published in the the American Journal of
Clinical Nutrition, researchers looked at data from more than 70,000 women who participated in the National Institutes of Health's women's health initiative between 1994 and 1998.
They found that the more women consumed added sugars and refined grains and the higher their score on the glycemic index (GI) - a measure of the rate carbohydrates are broken down and absorbed by the body - the more they were at risk of new-onset depression.
Those who had a different sort of diet - one with more dietary fiber, whole grains, vegetables and non-juice fruits - had a decreased risk.
"This suggests that dietary interventions could serve as treatments and preventive measures for depression," wrote James Gangswisch, an assistant professor of psychiatry at Columbia University Medical Center, and his co-authors.
