Do we need extra vitamins?
Many people believe that taking vitamin supplements is the best
safeguard（保护、保卫） against the dangers of an incomplete diet, but this should be ①a last resort (最后手段)rather than a way out of a problem. Even if there is a genuine（真实的，真正的；诚恳的） need for extra vitamins, then sooner or later the question arises（出现；发生；站立） \often?\Standards Committee guardians②保护者 of our laws on food purity, labelling（标记，贴标签；标明） and advertising clams（保持沉默，闭嘴不言） and descriptions) suggest in their recent report to the government that we do not need any extra vitamins.

The blame for faulty eating habits is often placed at the door of the ubiquitous③（a. being everywhere, esp. at the same time 普遍存在的） junk and convenience foods. As we have seen, some of these are not the criminals they are made out to be White bread is only slightly些微地，轻微地；纤细地less nutritious than brown bread and frozen vegetables can be almost as \fresh food. There are very few foods which can really be described as pure rubbish. Many pre-packed goods contain too much sugar and we would all benefit by avoiding these, but most tinned, processed处理的，加工过的and dried foods contain useful amounts of fat, protein, carbohydrate④（n. 碳水化合物）, vitamins and minerals矿物；矿产，矿产品.

正常的饮食是什么样的饮食？‖这样的问题。许多人心里对这两个问题还有点拿不不准尽管没有多少人熟悉食品标准委员会所呈报告中的措辞，但人们确实不由得要问，他们的饮食是否合理。不良的饮食习惯常常归咎到随处出售的没营养的食品和方面食品上。如我们所知，这些食品中的某些食品并不象人们认为的那要间（形成不良饮食习惯的）罪魁祸首。白面包比黑面包只是稍微少了点儿营养，而冷冻的蔬菜几乎和新鲜的食物一样的―新鲜‖。真正可以说成是纯粹没有营养的食物是非常少的。许多包装好的食品含糖太多，避开它们对我们都有好处，多数罐装食品、加工食品和烘干食品含有大量的脂肪、蛋白质、碳水化合物、维生素和矿物质。往方便食品（如比萨饼或汉堡包）上加少许的水果或另外添加一道色拉会把快餐变成搭配均匀的营养餐。 'Junk' food is difficult to define定义.
