According to new research, too much sugar doesn't just lead to weight gain, but also depression, anxiety and stress.

糖吃起来或许很甜——但是它对身体的影响却与甜相去甚远。新研究表明，过量的糖分不仅导致体重的增长，也会导致抑郁、焦虑和压力。

Eating a diet high in fructose as a teenager makes depression and anxiety worse, scientists found.

科学家发现，青少年摄入高糖分食物会加重抑郁和焦虑情绪。

It also alters how the brain response to stress, they said.

他们说，过高的糖摄入也会改变大脑对压力的应对方式。

 Fructose is a sugar found naturally in fruits and vegetables but is also added to processed foods and drinks - from biscuits to ice cream.

水果和蔬菜中富含天然果糖，但加工食品和饮品中，比如饼干和冰淇淋，都会添加果糖。

Scientists have found fructose appears to be linked to serious modern epidemics such as cancers, heart disease, hypertension, kidney damage, type 2 diabetes and even dementia.

他们发现果糖似乎与癌症、心脏病、高血压、肾功能损伤、2型糖尿病甚至是老年痴呆症有关。

But now researchers say it also stimulates pathways in the brain that affect how it responds to stress, which have important effects for behaviour.

然而，目前研究人员称果糖对大脑中的神经通路也有刺激作用。这些神经通路会影响大脑对压力的应对，从而对人的行为具有重大影响。
