Many people crave sweets when they're sad or anxious. I've heard lots of people say things like "I was so sad I ate a huge piece of cake with a scoop of ice cream," or "I'm so nervous, I need some chocolate." But do sugary sweets really make people better or calmer? Although it may seem so, there are studies that show sugar can actually make anxiety and depression worse.
According to this page, processed sugars can easily and quickly be absorbed into our bodies, causing our blood inuslin level to rise; this then raises the endorphin level, and since endorphin is a "mood upper," people feel happier and/or calmer after consuming sugars. However, if you continue to take in lots of sugars, the brain's endorphine sites "slow production or close sites to regulate the amount of endorphines in the brain." When the available amount of endorphines in the body decreases, it can cause slight to severe depression. Anotehr site says that suagr gives your blood gloucose level sudden ups and downs, which can cause fatigue, irritability, insomnia, poor concentration, depression, and anxiety, etc.
Our bodies are naturally provided with a "massive dose of sugar" that helps keep blood sugar stabilized. Insulin in our bodies act as a "downer," neutralizing the sugar. When the initial effects (happy, calm, etc.) of sugar wear of, the effect of insulin stays, causing a negative mood swing (since insulin is a "downer.") - the lack of endorphines in the brain, plus insulin's effect, can result in depression and anxiety. An individual then might eat more sugars to feel better, this results in a "vicious cycle of addiction."
Next time when you're sad or nervous, consider the negative effects that sugar might cause, and remember not to comsume too much sugar becuase it might make things worse.
