In a study of 452 elderly Greeks, Swedes and Australians,1 researchers analyzed sun-exposed areas of subjects' skin for degrees of cutaneous skin damage. They then analyzed the subjects' diet and compared the results. Regardless of genetic background, there was an association between skin wrinkling and the types of foods people regularly consumed. There was not a ranking as to best and worst foods. (Therefore, the following lists are not in order.)
Protective Foods Nonprotective Foods vegetables red meat fruits butter nuts margarine olive oil whole milk legumes soft drinks yogurt cocktails eggs potatoes whole grains cakes water pastries
I was not surprised that the protective foods tended to be higher in nutrient density, antioxidants and fiber, and would be considered anti-inflammatory, while the nonprotective foods were generally higher in saturated fats, sugar and empty (low-nutrient) calories.
This study does not include lifestyle factors. Generally, people who eat more foods from the protective category also have fewer "bad" habits (i.e., lack of exercise and alcohol and tobacco use) and more "good" habits (such as regular exercise and lower usage of harmful substances), which also will slow biological markers of aging.
Finally, please note that this study looked at whole foods. Don't be surprised if the folks who sell fruit and vegetable pills unfairly extrapolate these results and claim their products help prevent wrinkles, when in fact, there is no evidence to support that claim.
