Casein in cheese may trigger dopamine receptors in the brain, study suggests

“This publication is available to the public through the National Institutes of Health through the US National Library of Medicine. http://www.ncbi.nlm.nih.gov/pubmed/25692302   I think dopamine response is a good thing in moderation. In four decades of medical practice, I never heard  an ER reporting an overdose of cheese.” Bill Chesnut, MD

 Casein in cheese may trigger dopamine receptors in the brain, study suggests

 NBC Nightly News (10/22, story 10, 0:20, Holt) reported that “if you ever joked you’re addicted to cheese, you may actually be right.” A study suggests that “a protein in cheese can release opiates that trigger dopamine receptors in our brain like certain drugs do.”

The Los Angeles Times (10/22, Harris) reported in “The Daily Dish” that the study, which was published Feb. 18 in PLoS One, “identified addictive foods from about 500 students who completed the Yale Food Addiction Scale, designed to measure if someone has a food addiction.” It appears that cheese is particularly “addictive because of…casein, a protein found in all milk products,” which, “during digestion…releases opiates called casomorphins” that in turn “trigger” dopamine receptors.
