Carbohydrates are a known collagen destroyer (along with smoking).Ok, so how do nutrients affect one's looks?
"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: collagenand 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."

Add to this the research that eating a high carbohydrate diet increases your body's need for many vitamins including C. (Taubes - Good Calories Bad Calories)
So I guess the worst of all worlds is a smoking donut junkie who hates vegetables.
