Excess Sugar Consumption Increases Depression Risk - Especially in Men

According to a study published on 28 July 2017, consuming high-sugar foods increases depression risk. This long-term study spanning 1985-2013 found that men consuming 67 grams or more sugar daily (2 cans of cola or 16 teaspoons of sugar) had, after 5 years, %23 more depression than others.

Excess Sugar Consumption

Published in Scientific Report, this study examined the relationship between mood disorders and sugar intake. It initially looked at mood and the tendency toward sugar consumption. Measurements were made to understand the link between sweet foods and drinks and mental health.

United Kingdom civil servants in different roles were followed for years and their sugar consumption analyzed. Recruited in 1985 and now approaching old age, approximately two-thirds were men and one-third women, totaling 10.308 participants. After initial data collection, questionnaires and clinical data were collected every 2-5 years.

Soft Drinks, Cakes and Biscuits

Analyses through 2013 were compiled, reporting consumption among the top 15 sweet products, such as cakes, biscuits, packaged fruit juices and carbonated drinks, by participants using at least 8 of them. Participants were grouped according to daily sugar consumption.

Men Were Grouped as Follows:

• 67 grams of sugar or more
• Between 39.5 and 67 grams
• Less than 39.5 grams

For Women:

• 51 grams or more
• Between 30 and 51grams
• Less than 30 grams

Analysis found that men consuming 67 grams or more sugar daily had, compared with other groups, particularly men consuming less than 39.5 grams daily, a %23 higher depression risk.

Researchers found no similarly clear data in women, but thought this might result from the smaller number of women.

In conclusion, this study suggests foods with added sugar may cause psychological as well as physical harm. Although men were thought more affected in this study, that does not mean it is harmless for everyone else.
