Ninety-nine out of every 100 packed lunches being eaten by primary school children are reported to be unhealthy and failing to meet nutritional standards.

So what should a healthy lunch contain and what foods should be left out?

According to advice from the Food Standards Agency,a healthy packed lunch should include:

? Meat, fish or a dairy source of protein

? Starchy carbohydrate, such as a wholegrain sandwich, to provide energy

? At least one portion each of a fruit and vegetable or salad

? Water or milk to drink, but diluted fruit juice and yoghurt drinks or smoothies are acceptable

The key foods to avoid are:

? Sweets and chocolate

? Snacks, like crisps, with added salt/sugar/fat

? Sugary and fizzy drinks

? Deep-fried foods and processed meats

? White bread - if children won't eat brown, try whole white sliced bread

Nutritional standards for school meals were introduced in 2006 and standards for vending machines, breakfast clubs and tuck shops came into force a year later.

In 2008, strict nutrition content guidelines for primary schools were introduced and extended to secondary schools in September 2009.

健康的午餐盒包括什么？

报告指出每100份小学生的午餐饭盒有99份是不健康的且没有达到营养标准。而健康的午餐应该包括什么又将去除什么？根据食品标准局建议，一份健康的午餐应包含下面这些食物：

1. 鱼、肉、富含蛋白质的奶类

2. 富含碳水化合物的淀粉，象提供能量的全麦三明治

3. 水或牛奶饮品，稀释的果汁、酸奶饮料或水果冰砂也可

主要避免以下食物：

1. 甜食、巧克力

2. 零食，象含盐、糖、脂肪的薯片

3. 含糖并带气泡的饮料

4. 过度油炸食品和经过加工处理的肉类

5. 白色面包--如果孩子不喜欢棕色面包便选择了纯白的切片面包

2006年建立了学校饮食的营养标准，对自动售货机、早餐店、糖果食品店进行了一年多的加强管理。

2008年制定了针对小学生的严格的营养含量标准，2009年9月这项标准又扩展到初中生。
