>Sugar causes depression
研究稱吃甜食加重抑郁

If you've been feeling especially blue, a new study suggests getting those visions of sugar plums out of your head.
一項(xiàng)新研究認(rèn)為，如果你覺得特別難過，那就別再想著糖果了。

Researchers at the University of Kansas say that the added sugars found in virtually all holiday sweets can induce inflammatory and neurobiological processes that are connected to depression and negative feelings.
堪薩斯大學(xué)的研究人員稱，幾乎所有人們在節(jié)假日里吃掉的糖果中都含有不健康的添加糖，這些糖會引發(fā)炎癥，還會誘發(fā)與抑郁和消極情緒相關(guān)的神經(jīng)生物學(xué)過程。

Seasonal-depression and winter-depression symptoms will push individuals to eat more sweets.
季節(jié)性抑郁癥和冬季抑郁癥的癥狀都會使人去吃更多的甜食。

This will, in turn, only create a vicious cycle of feeling down and eating sweets to feel better, only to end up feeling even worse.
而這么做只會造成一個惡性循環(huán)：心情低落，吃甜食感覺好些，最終卻令人心情更糟。

Researchers said the inflammation caused by excess sugar is the number one contributor to depressive thoughts.
研究人員表示，過多糖分引發(fā)的炎癥是導(dǎo)致抑郁心緒的首要因素。

They recommend non-processed foods, particularly those rich in plant-based and Omega-3 fatty acids, in order to combat depression on a dietary level.
他們建議人們吃未加工的食品，尤其是那些富含植物脂肪酸以及歐米伽-3脂肪酸的食物，從而從飲食上對抗抑郁癥。
