Phosphorus -- the invisible additives 磷 -- 隐形的食物添加剂

Processed foods are a big part of our daily diet. We are so used to yogurts, cheeses, noodles, cereals, cakes, biscuits, deli meats, nuggets, hot dogs, sauces, fruit drinks and carbonated beverages, which are all high in phosphorus. Phosphorus has a wide function as food additives, from preserving moisture and color, anti-caking, to acidifier, leavening agent and stabilizer. Phosphorus additives can present in food in many forms and most people are not aware about it. What is the concern of having too much phosphorus? Studies have shown that dietary exposure to high levels of phosphorus could be increasing the cardiovascular disease.

Phosphorus is an essential nutrient naturally present in some food like egg yolk, dairy products and meat. It is an essential nutrient for bone and teeth, energy production and other metabolic processes. It is hard for you to know how much you are taking in since the amounts can vary between brands. Even the nutrient database is hard to trust because the data is based on food types, rather than brands. Labeling of Daily Value (DV) is based on 1000 mg while the Recommended Daily Allowance (RDA) is set at 700 mg for adults.



加工食品已是我们饮食中的一大部分，不管是乳酪，乳酪，面类，早餐谷粮，蛋糕，饼干，熟肉制品，鸡块，热狗，调味酱，果汁饮料和碳酸饮料，都含有大量的磷。磷是一个具有广泛作用的食品添加剂。它可用于保存食品中的水分和颜色，抗结块，也可以是酸化剂，膨松剂和稳定剂。磷，以多种形式存在于食物，但大多数人都没有意识到。但摄取有过多的磷有什么问题吗？有研究表明，饮食中摄取过多的磷可能会增加患上心血管疾病。

磷是人体必需的营养素，天然的存在于食物中，如蛋黄，乳制品和肉类。是保持骨骼和牙齿健康，身体产生能源和其他代谢过程中的一种必需营养素。要知道您每天摄入多少磷是相当困难的，因为不同的品牌存在着相当的差异。恐怕连营养数据库的质料也不能提供这一方面的质料，因为数据库是根据食物种类分类，而非依据品牌。即使是每日价值（DV）标签也是基于1000毫克，而成人的每日建议摄取量（RDA）只有700毫克。
