Summer outings will do the whole family good only if you know that the castle, zoo or park has a decent café. Otherwise, unless you got up early to make sandwiches, you risk feeling resentful as you shell out on rubbishy kids' food in a cafeteria.

A survey published last month by Lacors, the body that regulates council services, found that most theme parks, wildlife parks, museums, leisure centres, heritage sites and farm parks offered children fatty, salty and sugary food. Not one of the 397 meals for seven to ten-year-olds tested by environmental health officers and trading standards officers at 220 attractions met the nutritional guidelines for schools.

The average children's meal surveyed had 44 per cent more salt than the maximum 1.2g recommended by the School Food Trust, which oversees school dinners.

A few sights, including National Trust properties, offer decent food for all ages. Elsewhere, even when salt-free nuggets are made from free-range chicken breast and ices are the creamiest of the local crop, children's meals may not include vegetables.

However, sausage, chips and beans won't do. We'd like to see fresh vegetables or salad included automatically in children's meals. Ask for a half portion of an adult meal and you may fare better on the veg front. But to guarantee healthy food on a day out, always go armed with carrot batons, celery sticks and stocks of fresh fruit.

如果你知道城堡，动物园和公园有较好的小餐馆，夏日外出对于整个家庭来说都是有益的。除非你很早起来做三明治，否则当你去自助餐厅吃糟糕的儿童食物后你会感到很气愤。

Lacors上个月刚公布调查显示，管理服务委员会的人发现许多主题公园，野生公园，博物馆，娱乐中心，古遗迹和农场公园给儿童提供的是高脂肪，高盐和高糖分的食物。提供给7岁至10岁儿童的397种食物中没有一种经过环境健康人员的检测，220个景点的权威贸易人员为孩子制定了专门营养指导方针。

调查显示每个儿童食物的盐份大于44％，这个数字比学校食品信托所推荐的最多1.2g的摄取量要多得多。学校食品信托主要关注学校的正餐。

包括美国信托基金在内的关注儿童的少数机构给所有年龄段的儿童提供优质食物。在任何地方，甚至不含盐的鸡块也是由农场放养的鸡脯做成的，冰淇淋是由本地农作物中提取的乳脂类做成的，而孩子们的膳食中可能不含蔬菜。

然而，香肠，炸土豆条和豆类也不能起到蔬菜的作用。我们更愿意看到在孩子们的膳食中包含新鲜蔬菜或者色拉。在半份成人膳食中你们可能发现蔬菜一定会出现在前面。为了保证在外游玩能吃到更健康的食物，最好携带胡萝卜，芹菜梗和个刚买的新鲜水果。
