Face facts: Too much sugar can cause wrinklesThe surprising reason eating too much can cause wrinkles--and 5 steps to ensure that it won't
Here, five steps to eat right and keep your skin looking its youngest:
1. Cut back on the sweet stuff in your diet.
It's not easy to eliminate sugar completely. Even whole grains, fruits, and vegetables turn to glucose--the type of sugar that fuels glycation--when digested. But limiting added sugar can help. Some guidelines: Keep added sugar to no more than 10% of total calories. If you're a 45-year-old woman of average height (5-foot-4), that's 160 calories (or 10 teaspoons) from added sugar--about the number in one 12-ounce can of Coca-Cola or six Hershey's Kisses. By comparison, the average American consumes 31 teaspoons per day of added sugar, or the equivalent of 465 calories.
10 Crazy Ways to Sweeten Without Sugar
Watch for hidden sugar in food. Many prepared foods contain hefty amounts of sugar--but it's hidden under aliases--including barley malt, corn syrup, dextrose, fruit juice concentrate, maltose, maple syrup, molasses, and turbinado--on ingredient panels. The key is determining how many teaspoons of sugar each serving contains. Doing this is easy: Check the nutrition label for sugars, which are listed in grams under total carbohydrates, and then divide that number by 4 (each teaspoon of sugar is equal to 4 g) to convert it to teaspoons. For example, if sugars are listed as 12 g, you're getting 3 teaspoons of sugar per serving.
Avoid high fructose corn syrup. This type of sweetener, which is made by changing the sugar in cornstarch to fructose (another form of sugar), is believed to produce more AGEs than other types. Because HFCS extends the shelf life of foods and is sweeter and cheaper than other sugars, it's a popular ingredient in soda, fruit-flavored drinks, and packaged foods such as breads, crackers, and other snacks. You can spot it in ingredient lists on nutrition labels.
2. Supplement your diet with at least 1 mg of vitamins B1 and B6 a day.
These vitamins proved to be potent AGE inhibitors in a number of published studies, says David J. Goldberg, MD, a New York Citybased dermatologist and a clinical professor of dermatology at Mount Sinai School of Medicine. B1 and B6 are plentiful in food, but taking a multivitamin--most of which deliver at least 1 mg of both Bs--ensures you're getting the daily value of 1.1 mg for B1 and 1.3 mg for B6 (1.5 mg after age 50).
3. Wear broad-spectrum SPF 30 sunscreen every day.
Significantly more AGEs occur in sun-exposed skin than in protected skin, according to the British Journal of Dermatology study.
4. Employ an inside-outside approach to antioxidants.
These free-radical fighters help keep sugar from attaching to proteins, so replenishing their supply--both by eating more antioxidant-rich fruits, nuts, and vegetables, such as cranberries, walnuts, and red bell peppers, and by applying topical antioxidants such as green tea and vitamins C and E--is a real skin saver. "It seems to be the best way to ensure that they reach the dermal layer of skin, where collagen and elastin are located," says Goldberg.
5. Use new ingredients that protect skin from sugar.
A growing number of products contain compounds like aminoguanidine and alistin, which have been shown to block the formation of AGEs (see at left). "Aminoguanidine attaches to molecules that start the glycation process and prevents them from binding to collagen and elastin," explains Grossman. "Alistin acts as a decoy, so it gets damaged instead of the proteins in your skin." In a study on Prescriptives Anti-AGE Advanced Protection Lotion SPF 25, which contains both ingredients, skin treated with the product had 21% fewer AGEs after 8 weeks than untreated skin. Sweet!

We don't know about you, but we prefer to do a little prep work before going full Monty—or even mostly Monty. And we don't mean three months of squats.

Plus, they're a little more fun than squats.
