你被充斥着垃圾食品的“食物沼泽”包围了吗？

昨天说到新鲜食品匮乏的地区叫做“食品荒漠”，实际与之类似的还有“食物沼泽”。

Food swamp refers to an area that has an abundance of fast food restaurants and other low-nutrition food options.
“食物沼泽”是指快餐店林立和被其他类似的营养价值较低食品充斥的地区。

乍看之下，“食品荒漠”(food desert)和“食物沼泽”都与食物相关，其实两者里提到的食物却截然不同。“食品荒漠”里的食物是健康食品，即新鲜蔬菜、瓜果、肉类和奶制品，而食物沼泽中出现的食品却是高热量、低营养的“垃圾食品”。因此，在学记时一定要区分清楚，谨防搞混。

For example:

The authority has mapped the entire city to measure access to healthier food within walking distance, and found many neighbourhoods would qualify as food swamps, with many more less healthy food stores than healthier ones.
当局绘制全市地图来评估在步行距离之内获得健康食物的难易程度，发现有不少社区可被称为“食物沼泽”，不健康食品店舖的数目多于健康食品店。

Food swamps are also found in both high and lower income neighbourhoods throughout the city, and there was no significant correlation between a neighbourhood's income and its chance of healthier food access.
调查还发现，高收入和低收入地区同样都有“食物沼泽”，且居民收入和接触健康食物的机会并无重大关联。
