It was decided to evaluate the exposition of patients on nitrates and nitrites contained in 6 whole day's standard hospital diets taken in various days. Studies were performed in June 1995. It was found that the mean daily intake of nitrates was 311 mg and the mean intake of nitrites were 2.16 mg per patient. The main source of nitrates were vegetables (85%), whereas the main source of nitrites were meat and meat-containing products. The presented results suggest that the diets containing early vegetables (especially cabbage) may be harmful for human health.
决定评估患者在不同日期摄入的6份全天标准医院饮食中所含硝酸盐和亚硝酸盐的暴露量。研究于1995年6月进行。结果发现，每位患者的硝酸盐平均每日摄入量为311毫克，亚硝酸盐平均摄入量为2.16毫克。硝酸盐的主要来源是蔬菜（85%），而亚硝酸盐的主要来源是肉类和含肉产品。所呈现的结果表明，含有早熟蔬菜（尤其是卷心菜）的饮食可能对人体健康有害。
