多吃生鲜果蔬有助于缓解抑郁症
Eating more raw(生的) fruits and vegetables can help ease depression(抑郁症) and other mental illness, according to experts from the University of New Zealand. More than 400 people aged between 18 and 24 from New Zealand and the US were surveyed for the research.
The result shows that raw fruits and vegetables consumption predicted lower levels of mental illness, such as depression, and improved levels of psychological well-being including positive mood and life satisfaction. "Our research also shows that eating raw fruits and vegetables is more strongly associated with better mental health. In other words, eating canned or processed fruits and vegetables is harmful for our health if we eat them all the time," lead author Kate Brookie said. 
In addition, experts also say people should be focusing more on the types of fruits and vegetables rather than the quantity. The best foods to eat include carrots, bananas, apples, fresh berries, cucumber, kiwifruit, dark leafy greens and citrus fruits. If we can often eat these fruits and vegetables, our health will be better and better.
