Like soda? The investigative/political magazine Mother Jones says there is scientific evidence that says the sugar in a medium can of soda diminishes your cells' ability to regenerate at about the same rate as smoking cigarettes.
According to the article, the Journal of Public Health published a study of 5,300 adults. In the study, they compared the cells of people who drink soda every day to those of their non-soda-drinking counterparts. In the soda group, the ends of the chromosomes — known as telomeres — were shorter, a sign of their cells' diminished ability to regenerate. Telomeres naturally shorten with age, but scientists say behaviors — including smoking — can shorten them prematurely.
