We Associate Sweets With Sadness
If you’ve ever craved sweets while feeling down, you’re not alone. Many people associate certain tastes with specific emotions. In 2015, research in The Journal of Clinical Endocrinology & Metabolism found that sweet cravings often arise from low levels of cortisol. Cortisol regulates emotional stress.
Essentially, low levels of cortisol can make people feel stressed or sad. When we eat sugar, we receive a cortisol spike. As a result, many people suddenly crave sweets when they feel overwhelmed.
