科盲或者英文盲才会说“再次证实素食降低肠癌风险”

拜托，仔细去看看人英文说得啥，再来宣传。
人只说有association，根本没建立因果关系。
人最后还说“As such, they say that IF the link between a vegetarian diet and reduced risk of colorectal cancer is found to be causal, following a vegetarian diet could be an important prevention strategy for the disease. ”。进一步强调，如果能建立因果关系，就能证明素食防癌。另一方面的意思就是，根本没有证明任何因果关系。
