Diet drinks linked to depression risk

Calorie-free drinks are not necessarily risk free.

A study has found a link between drinking dietfizzy or diet fruit drinks and an increased risk of depression.

The researchers analysed information from more than 263,900 US adults aged 50 to 71, who answered questions about their beverage consumption between the years 1995 and 1996. About 10 years later (2004 to 2006), the same people were asked if a doctor had diagnosed them with depression since the year 2000.
