Do You Crave Salt Or Sugar?
A friend recently posted a link on Facebook to a report by a research team from Duke University Medical Central along with some Australian scientists who found that, “Addictive drugs may hijack the same nerve cells and connections in the brain that serve a powerful, ancient instinct: the appetite for salt.” One of the co-authors of the report, Wolfgang Lietke, M.D., Ph.D. said, “We were surprised and gratified to see that blocking addiction-related pathways could powerfully interfere with sodium appetite. Our findings have profound and far-reaching medical implications, and could lead to a new understanding of addiction and the detrimental consequences when obesity-generating foods are overloaded with sodium.” You can read more about the study and its implications for addiction research here.
This finding reminded me of something Tim Bilkey M.D. told me in a consultation following his diagnosis of my ADHD. He noted that in his clinical practice he was finding that patients with ADHD had cravings for salt in snacks not sugar. He wondered whether there might be some connection to the fact that the most commonly prescribed drugs for this condition–Dexedrine and amphetamine–are technically salts.
Very intriguing findings (says a salt junkie!).
