In experimental studies, the laboratory animals were given option to choose either saccharin-mixed drinking water or normal drinking water. About 50% of the animals were on cocaine injections. Shockingly, cocaine-received animals chose normal drinking water while the rest of the animals rushed for saccharin-mixed drinking water. Other similar studies reported that common table sugar was preferred by the animals over cocaine. The pleasure of sweetness, sheer intensity of sugar might be the cause of more addictiveness than cocaine, the scientists believe.
The sugar cravings associated mesolimbic (brain) reward pathway is biologically equivalent to cocaine addiction pathway.Upon abrupt withdrawal of sugar exposure, the animals exhibited characteristics of withdrawal syndrome such as stress, anxiety and behavioral changes, the study concluded.
Some mainstream experts believe that cow’s milk and wheat contains certain opioid-like substances (casomorphin and gluten exorphins) that are equally addictive to heroin.
