Sugar not only affects your weight, but your mental health as well, says study!

New Delhi: The fact that too much sugar is bad for your oral health and your weight is common knowledge.

But, a study carried out on July 27 revealed that it can also negatively affect your mental health, thereby attracting some amount of skepticism from experts.

Researchers at University College London (UCL) compared the reported sugar intake of more than 8,000 people in a long-term British study, to their mood.

The study participants, civil servants, were monitored from 1985-1988, and filled out a questionnaire every few years thereafter.

Researchers examined data from that study for an association between sugar intake and "common mental disorders" (CMD) such as anxiety and depression.

It was found, that men with a higher intake of sweet foods and drinks had an increased likelihood to develop CMD after five years, and a general "adverse effect" on mental health for both sexes.

The study, published in the journal Scientific Reports, concluded that "lower intake of sugar may be associated with better psychological health."

However, Catherine Collins, dietician and spokesperson for the British Dietetic Association, said this recommendation was "unproven".

Problems with the study, she said, included that sugar consumption was self-reported, and that sugar intake from alcohol was not counted.

The researchers, she said, appeared to confuse naturally-occurring sugar from foodstuffs such as milk, and "free sugars" added to hot drinks or in sweets.

"The dietary analysis makes it impossible to justify the bold claims made by the researchers about sugar and depression in men," Collins said via the Science Media Centre in London.

"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."

Nutrition expert Tom Sanders agreed the results should be interpreted "with caution".

"From a scientific standpoint it is difficult to see how sugar in food would differ from other sources of carbohydrate on mental health as both are broken down to simple sugars in the gut before absorption," he said.
