Sugar is a staple in the American diet, but consuming too much of it can be detrimental to health. Many people find it difficult to restrict their intake of foods with added sugars, and this can contribute to obesity and related health problems. Research shows that eating too much sugar can produce behaviors and changes in the brain that are similar to the effects of drugs of abuse, like alcohol or nicotine. These behaviors include bingeing, withdrawal and craving, and this can lead to a cycle of addictive overeating. In addition, change in the brain’s dopamine and opioid systems have been seen in response to overeating sugars. Since many food products contain multiple types of added sugars, in excess amounts, the effects on behavior and brain functioning have widespread implications.
