Too much sugar may be bad for your mood, suggests a British study in Scientific Reports, which tracked the diets and health of 8,000 people, none of whom were being treated for mental illness at the start.
Compared to men who consumed the least sugar (less than 40 grams a day) from sweets such as cakes, candies, and ice cream as well as sugary beverages, men who consumed the most sugar (more than 67 grams a day) were 23 percent more likely to be diagnosed with depressive symptoms over a five-year period. For perspective, a 12-ounce can of soda has about 40 grams of sugar.
No association was seen in women, however, perhaps because of their smaller number in the study, gender differences in depression pathology, or chance.
