糖食太多會長皺紋 (CNN英文新聞) - 養生

ATLANTA, Georgia (CNN) -- Before you grab that leftover piece of Halloween
candy, you might want to rethink the decision. It could cost you, in
wrinkles. It now appears the sweet stuff might make us happier and possibly
more hyper, but also make us look older.

Foods that turn into glucose in the body also can make you look older,
researchers say.

學者表示, 會在你體內轉化成葡萄糖的食物可能會讓你看起來更老。

A study in the British Journal of Dermatology breaks down the science of how
this works, putting the aging blame on a process called glycation. Glycation
occurs when sugars -- not just refined sugar, but anything that turns into
glucose in your body -- are eaten and the glucose hits your bloodstream. As
they float along, they search out and latch on to proteins and form a new
molecule called advanced glycation end products, or appropriately shorted to
AGEs.

一份由英國皮膚醫學期刊發表的研究顯示，導致老化的原因可能是起因於體內的glyca-
-tion。Glycation是指食用糖類後在體內會轉化成葡萄糖進入血液的過程，所指的糖類
不僅僅限於精緻加工過的糖製品。葡萄糖會搜尋並依附在蛋白質（不太確定是要叫
蛋白質，還是朊）上並形成名叫Advanced Glycation End Products (AGEs)的新分子。

The more sugar you eat, the more AGEs you produce. As they multiply, these
molecules wreak havoc with adjacent proteins. The most vulnerable of these
proteins are just the ones we want to stay strong: collagen and elastin. They
are the compounds responsible for keeping our skin firm and elastic.

當你食用愈多的糖，身體就會產生愈多的AGEs，而過多的AGEs會破壞其他相鄰的蛋白質
/朊。而其中如collagen和elastin是我們最想留住的，但卻最易受到損害，他們主要維
持皮膚緊緻有彈性。

The result is sagging, wrinkled skin.

後果就是鬆弛又佈滿皺紋的皮膚。

But before you throw in the towel and start saving for plastic surgery, there
is some good news about this newly reported form of sugar blues. There are
some things you can do to put the sticky sweet damage into rewind.

The first place to start is probably the most obvious: Limit the sugar in
your diet. Kerry Neville, a registered dietitian and spokeswoman for the
American Dietetic Association, says, "The lower you can get the added sugar
in your diet, because they aren't adding anything to your diet, the better."

（所以減少多餘的糖份吸收）

But those added sugars can be hard to ferret out. "Eliminating them all is
hard," Neville contends. "Often it is a matter of where you are getting the
added sugar. Food labels don't spell out added sugars," so look for words
such as corn sweetener, corn syrup, sucrose or sorghum, to name a few.

（多注意食品是否有使用玉米糖漿，蔗糖，高樑糖漿等添加物）

Overall, the latest finding about wrinkles sits well with the Seattle,
Washington-based nutritionist, because, as Neville points out, "Americans eat
too much sugar, and it appears that the threat of making them fat doesn't
seem to discourage excess sugar eating. So this latest wrinkle scare might
just do the trick. That is great."

But Dr. Darren Casey, a dermatologist and dermatological surgeon in Atlanta,
Georgia, isn't so worried about potential skin damage from sugar. "Sun and
smoking are the leading cause of wrinkles," he said. His best advice, aside
from getting plenty of antioxidants in your diet, is to take "a chewable
vitamin C."

（不過也有醫師指出皮膚老化的主因還是陽光和菸害，除了盡量在飲食中攝取足夠的抗
　氧化物外，可以多補充維他命Ｃ嚼碇或軟糖〔可以嚼的都行〕。

And whether your skin is sugar damaged or just environmentally challenged,
Casey says, you can't go wrong by using products that contain retinoids,
which are a class of compounds related chemically to vitamin A. Those
products, whether over the counter or prescription, are the best to help
soften fine lines or wrinkles, which in turn will make you look younger and
may just make you act sweeter, no sugar necessary.

（對於已經受到傷害的皮膚，使用含有retinoids[近似維他命A的組成物]成份的產品
將有效減緩老化症狀。）
