Sugar is often associated with energy and short-term feelings of well-being, but research indicates that a high intake of added sugar may have negative effects on the brain, according to Healthline.
Several studies suggest that a diet high in sugar can make it more difficult to remember information and make decisions.
A recent study published in Royal Society Open Science found that young adults performed worse on memory tests after just one week of consuming high amounts of added sugar and saturated fat.
Researchers are still investigating the field, but the findings suggest that diet may play an important role in brain function.

May affect stress levels
Many people turn to sweet snacks when they feel pressured or stressed.
According to research published in The Journal of Clinical Endocrinology & Metabolism, sugar may temporarily reduce the body's stress response by influencing the release of the stress hormone cortisol.
However, the effect is short-lived. Researchers believe this may lead people to seek out sugar more frequently when they feel stressed.
At the same time, a high sugar intake can increase the risk of obesity and other health problems.
