To examine the possibility that aluminium beverage cans contribute to the dietary level of aluminium.
The aluminium content of a variety of beverages from aluminium cans and glass containers was measured.
The contents of 106 aluminium cans and bottles representing 52 different beverages all had a higher aluminium content than Newcastle tap water at 1.4 mumol/L, ranging as high as 385 mumol/L. Non-cola soft drinks averaged 33.4 mumol/L from cans and 5.6 mumol/L from bottles. Cola drinks averaged 24.4 mumol/L from cans and 8.9 mumol/L from bottles, whereas beer in cans or bottles averaged about 6 mumol/L.
In general, the aluminium content of beverages from aluminium cans was higher than that from glass containers, and it rose with decreasing pH. Within a given category there was a wide variation in aluminium content. If the speculative link between aluminium intake and Alzheimer's disease is established then beverages from aluminium cans, particularly soft drinks, may be a risk factor.
探讨铝制饮料罐是否会导致饮食中铝含量升高。
测量了来自铝罐和玻璃瓶的多种饮料中的铝含量。
代表52种不同饮料的106个铝罐和玻璃瓶中的饮料，其铝含量均高于纽卡斯尔自来水（1.4微摩尔/升），最高可达385微摩尔/升。非可乐软饮料铝罐平均含量为33.4微摩尔/升，玻璃瓶平均含量为5.6微摩尔/升。可乐饮料铝罐平均含量为24.4微摩尔/升，玻璃瓶平均含量为8.9微摩尔/升，而罐装或瓶装啤酒平均约为6微摩尔/升。
总体而言，铝罐饮料中的铝含量高于玻璃瓶饮料，且随着pH值降低而升高。在同一类别中，铝含量存在很大差异。如果铝摄入与阿尔茨海默病之间的推测联系得到证实，那么铝罐饮料，尤其是软饮料，可能是一个风险因素。
