Many people turn to sugary treats as a quick fix for fatigue or stress, but research cited by Healthline suggests that sugar does not necessarily improve mood.
Several studies have linked a high sugar intake to poorer mental well-being.
This includes an increased risk of mood disorders and higher levels of anxiety among older adults, according to studies published in Scientific Reports and Nutrients.
Short-term relief
Sugar may, however, provide a temporary sense of relief.

A study published in The Journal of Clinical Endocrinology & Metabolism found evidence that sugar may reduce the body's release of the stress hormone cortisol.
The problem is that this short-lived effect can make it more difficult to resist sugary foods.
A high sugar intake may also affect inflammation and the gut microbiome, which researchers believe could influence brain function.
Cut back on sugar
For some people, suddenly eliminating processed sugar can lead to restlessness, irritability, confusion, and fatigue.

According to the Scientific Reports study, men who consumed at least 67 grams of sugar per day had a higher risk of receiving a depression diagnosis within five years.
More research is still needed, and the studies do not necessarily show that sugar alone is the cause.
However, consuming large amounts of sugar may be associated with poorer mental health and an increased risk of anxiety and depression.
