A Conference was held in Paris in 2006 to review the safety and benefits arising from the replacement of sucrose with the intense sweetener aspartame. The intakes of aspartame are only about 10% of the acceptable daily intake, even by high consumers, so that the safety margin is about 3 orders of magnitude. The safety of aspartame was confirmed in the EFSA Opinion of a recent controversial rodent cancer bioassay. There is increasing evidence that even modest reductions in the intake of calories can reduce the risk factors associated with a number of diseases, such as diabetes and cardiovascular disease. A key issue addressed at the conference was whether the replacement of sucrose with aspartame could result in a prolonged decrease in calorie intake that was of similar magnitude to that necessary to produce a health benefit. A recent meta-analysis of published data showed that an adequate, prolonged weight reduction could be achieved with aspartame. It was recognised that risk assessment alone gave an unbalanced impression to regulators and consumers, and that in the future quantitative risk-benefit analyses should be able to provide more comprehensive advice.
2006年在巴黎召开了一次会议,以审查用高强度甜味剂阿斯巴甜替代蔗糖所带来的安全性和益处。即使是高摄入量人群,阿斯巴甜的摄入量也仅约为每日可接受摄入量的10%,因此安全系数约为3个数量级。欧洲食品安全局(EFSA)近期对一项有争议的啮齿动物癌症生物测定的意见证实了阿斯巴甜的安全性。越来越多的证据表明,即使适度减少热量摄入也能降低与多种疾病(如糖尿病和心血管疾病)相关的风险因素。会议讨论的一个关键问题是,用阿斯巴甜替代蔗糖是否会导致热量摄入长期减少,其幅度与产生健康益处所需的幅度相似。最近对已发表数据的荟萃分析表明,使用阿斯巴甜可以实现充分、长期的体重减轻。人们认识到,仅进行风险评估会给监管机构和消费者留下不平衡的印象,未来定量风险效益分析应能够提供更全面的建议。
