Sugar May Contribute to Wrinkles
Quote:
If the promise of a slimmer waistline hasn't curbed your sweet tooth, maybe the desire for smooth skin will. It's a bitter pill to swallow, but experts now believe that a lifetime of overeating sugar can make skin dull and wrinkled.
At blame is a natural process that's known as glycation, in which the sugar in your bloodstream attaches to proteins to form harmful new molecules called advanced glycation end products (or, appropriately, AGEs for short).
The more sugar you eat, the more AGEs you develop. "As AGEs accumulate, they damage adjacent proteins in a domino-like fashion," explains Fredric Brandt, MD, a dermatologist in private practice in Miami and New York City and author of "10 Minutes 10 Years."
Most vulnerable to damage: collagen and elastin, the protein fibers that keep skin firm and elastic. In fact, collagen is the most prevalent protein in the body.
Once damaged, springy and resilient collagen and elastin become dry and brittle, leading to wrinkles and sagging. These aging effects start at about age 35 and increase rapidly after that, according to a study published in the British Journal of Dermatology.
