Mental illness: regular soft drink intake may increase risk
29 January 2010
People who regularly consume large amounts of soft drink may be at increased risk of depression, an Australian study shows (Public Health Nutrition 2010; in press).
A population-based survey of nearly 5000 people linked consumption of more than half a litre of soft drink per day to depression and psychological distress, but not anxiety.
The authors said it was unclear whether the effect related to the sugar content of soft drinks or to other factors.
Meanwhile, other Australian researchers have found that, among 1000 randomly selected women, a Western diet high in refined grains, fried food, beer and sugary products was associated with having a mood disorder (American Journal of Psychiatry 2010; in press). A balanced diet of vegetables, fruit, meat, fish and whole grains was linked to lower odds of having depression and anxiety.
