Eating a lot of sweets is not only bad for your waistline, it’s also damaging to your skin. According to experts, overeating sugar can make your skin dull and wrinkled.
Here’s an important excerpt from a Prevention.com article:
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.
Besides damaging collagen, a high-sugar diet also affects what type of collagen you have—another factor in how resistant skin is to wrinkling, says Brandt. The most abundant collagens in the skin are types I, II, and III, with type III being the most stable and longest lasting. Glycation transforms type III collagen into type I, which is more fragile. “When that happens, the skin looks and feels less supple,” says Brandt. The final blow: AGEs deactivate your body’s natural antioxidant enzymes, leaving you more vulnerable to sun damage—still the main cause of skin aging.
Well then, I should rethink about eating the red velvet cupcakes that I just baked (or not).
