When we think of environmental factors that age our skin, the usual culprits pop into our heads—sun and pollution.

After all, the sun and pollution are hard to avoid, and while we can protect ourselves by using sunscreen and staying indoors, nothing is 100 percent foolproof.

We often fail to recognize, however, that many things we put in our mouth can also age us. One of the best examples of an ingested substance that ages our face is added sugar. To avoid sugar’s aging attributes, cut it out of your diet—it’s foolproof!

How does sugar damage youthful skin? Researchers have found that excessive sugar intake may damage collagen and elastin, two important proteins in the body that help our skin stay smooth and tight by providing structure and support. It’s the loss of collagen and elastin that eventually leads to wrinkling.

You may think added sugar is impossible to avoid. It seems to be everywhere these days, in foods you’d guess (like cola, candy and ice cream) as well as some you wouldn’t (like corn chips, salad dressing, processed stuffing and chicken coating, bread crumbs, breakfast cereals, mayonnaise, crackers, cough syrup and frozen dinners). Following a whole foods diet is an important step towards eliminating added sugar from your diet and will eventually bring your closer to more fabulous skin. In addition to great skin, it will also keep your risk of heart disease, stroke and diabetes down.
