绝大多数学过分子生物学的和方舟子观点相似?有调查吗?
转基因长期对人体、动植物、生态的影响,学过分子生物学就能保证没问题?
关于长期影响,这是联合国粮农组织和世界卫生组织共同设立的专家委员会关于转基因食品安全的报告中的结论部分关于转基因食品的长期安全方面的结论。它只是说:
上市前的安全评估已经确认了这些食品和传统食品一样安全。相应地,也认为由转基因而特别导致的长期影响看来非常不可能。
它也提到,即使打算做长期的研究,要把转基因的影响从其它可能的影响因素中分离出来,也是很困难的。因而,长期的研究不仅是没有必要,也是不现实的。
Safety aspects of genetically modified foods of plant origin

7. Conclusions

4. The Consultation considered the issue of long term effects from the consumption of
genetically modified foods and noted that very little is known about the potential long term
effects of any foods. In many cases, this is further confounded by wide genetic variability in the
population, such that some individuals may have a greater predisposition to food-related effects.
In this context, the Consultation acknowledged that for genetically modified foods, the premarketing
safety assessment already gives assurance that the food is as safe as its conventional
counterpart. Accordingly it was considered that the possibility of long term effects being
specifically attributable to genetically modified foods would be highly unlikely. Furthermore,
it was recognised that observational epidemiological studies would be unlikely to identify any
such effects against a background of undesirable effects of conventional foods. Experimental
studies, such as randomised controlled trials (RCTs), if properly designed and conducted, could
be used to investigate the medium/long term effects of any foods, including genetically modified
foods. Such studies could provide additional evidence for human safety, but would be difficult
to conduct. In this respect, it is also important to recognise the wide variation in diets and dietary
components from day to day and year to year.
