Men making themselves depressed by eating too much sugar, study suggests
Sugar consumption was compared with rates of common mental disorders in more than 5,000 men and 2,000 women between 1983 and 2013.
Millions of sweet-toothed British men could be making themselves anxious and depressed by consuming too much sugar, a study suggests.
Scientists found that men who consumed more than 67 grams of sugar per day increased their risk of mood disorders by more than a fifth compared with those with an intake of less than 39.5 grams.
And since the average British man has a 68.4 gram per day sugar habit (according to the National Diet and Nutrition Survey published in 2013), the findings do not bode well for the mental health of the UK male population.
The study ruled out the possibility that the results can be explained by unhappy men comforting themselves with sugary treats.
“There are numerous factors that influence chances for mood disorders, but having a diet high in sugary foods and drinks might be the straw that breaks the camel’s back.
“There is increasing evidence for the physical damage sugar has on our health. Our work suggests an additional mental health effect.”
For reasons that are unclear, the study which looked at thousands of civil servants of both sexes found no link between sugar intake and new mood disorders in women.
The findings are based on data from Whitehall II, a major long-term investigation into physical and mental health problems encountered by people working at different levels of the UK civil service. Sugar consumption was compared with rates of common mental disorders in more than 5,000 men and 2,000 women between 1983 and 2013.
British adults consume roughly double recommended levels of added sugar, three quarters of which comes from sweet foods and drinks, said the researchers.
Dr Knuppel added: “Sweet food has been found to induce positive feelings in the short-term. People experiencing low mood may eat sugary foods in the hope of alleviating negative feelings. Our study suggests a high intake of sugary foods is more likely to have the opposite effect on mental health in the long-term.”
Co-author Professor Eric Brunner, also from UCL, said the new sugar tax on soft drinks which takes effect in April 2018 was a “step in the right direction”.
He said: “Our findings provide yet further evidence that sugary foods and drinks are best avoided … The physical and mental health of British people deserves some protection from the commercial forces which exploit the human ‘sweet tooth’.”
However, some experts commenting on the research urged caution.
Catherine Collins, from the British Dietetic Association, said: “Whilst the findings as reported are interesting, the dietary analysis makes it impossible to justify the bold claims made by the researchers about sugar and depression in men. More surprising is the lack of reported effect in women, who have a far more emotional relationship with food.
“Reducing intake of free sugars is good for your teeth, and may be good for your weight, too. But as protection against depression? It’s not proven.”
