Problem: Your Moods Are All Over The Place
Sugar has a powerful impact on the brain. So, it’s not surprising that eating too much can wreck your mood. Some studies have found that high glucose levels cause affect hormones and mood. Others show that sugar crashes are associated with moodiness. In the long term, several studies suggest that there may be a link between high-sugar diets and depression and other mood disorders. One study found that women with high sugar intake had the highest rates of depression, while women with low sugar intakes had the lowest. The exact cause of this is unknown.
High sugar consumption is associated with inflammation, which is linked to depression risk. Eating sugar also affects the cells that release dopamine. Dopamine is a neurotransmitter, a chemical that brain cells use to communicate, that plays an important role in mental health. Some simple sugars, including glucose and fructose, can also affect the production of BDNF, a molecule that is critical to brain function. Low BDNF levels are associated with depression.
