(美国儿科学会在网上发布的一份政策声明和技术报告称，家庭应减少接触食品色素、防腐剂和包装材料中发现的合成化学物质，因为越来越多的研究表明它们可能会损害儿童的健康。)” 以及第二段 “The statement also suggests improvements to the food additives regulatory system, including updating the scientific foundation of the U.S. Food and Drug Administration safety assessment program and retesting all previously approved chemicals. (声明还建议改善食品添加剂监管体系，包括更新美国食品和药物管理局安全评估项目的科学基础，并重新测试所有以前批准的化学品。)” 可知，根据美国儿科学会的报告，人们应该在日常生活中尽量避免使用食品添加剂，并修改有关食品添加剂的规定，以应对食品添加剂的问题。故选D。

children are more sensitive to what they eat and drink than adults

children usually eat and drink more unhealthy food than adults

children are just too young and weak to protect themselves

children’s organs are easier to be damaged and hard to recover

An early injury to their organ systems can have lifelong and permanent consequences. (食品添加剂的潜在有害影响对儿童尤其重要，因为他们对接触化学物质更敏感，因为相对于体重而言，他们比成年人吃的和喝的更多，而且他们还在生长发育中。早期对他们器官系统的损伤可能会造成终身和永久的后果。)” 可知，莱昂纳多·特拉森德认为，食品添加剂对儿童的危害比成人大，因为研究表明，儿童的器官更容易受损，也更难恢复。故选D。
