If you've ever said, "I'm completely addicted to sugar," you might actually be correct. A recent study of 579 individuals found that those who had genetic changes in a hormone called ghrelin consumed more sugar (and alcohol) than those who did not have this gene variation.
Ghrelin is a hormone that tells the brain you're hungry. Researchers think that the genetic components that effect your ghrelin release may have a lot to do with whether or not you seek to enhance your neurological reward system through your “sweet tooth.” Findings of this study were similar to a study conducted in 2012.
The question, though, is: How come sugar “addiction” only started to come to the fore since the 1970s? What’s the likelihood that up to 70% of the developed world’s population would become prone to acquiring this particular genetic impairment in less than two generations? Until someone actually calculates it, or proves it with “genome forensic,” we should be very skeptical about accepting the claim that the genome of most of us has been affected that way in such a short time. I know I am.
