Tim Harford: 1939年,一位医生为了研究坏血病的症状,给自己制定了一份缺乏维生素C的饮食,并记录了其身体变化,这展现了早期对坏血病研究的探索过程。尽管人们在1930年代已经知道坏血病是由缺乏维生素C引起的,但人体内维生素C的流失速度很快,因此症状的出现存在延迟,这导致了对坏血病的误解和治疗方法的反复探索。尽管英国海军在1747年就发现了柠檬可以预防坏血病,但由于多种原因,包括柠檬和青柠中维生素C含量不同,以及维生素C易受环境因素破坏等,导致他们对坏血病的理解和治疗方法存在混乱。英国海军转向蒸汽船后,航行速度加快,补给频繁,导致坏血病症状出现的时间缩短,从而掩盖了他们使用的坏血病疗法无效的事实。1907年,两位挪威科学家发现豚鼠也会患坏血病,这一发现有助于澄清坏血病的病因,并最终解决了长期以来对坏血病的误解。詹姆斯·林德在1747年进行的随机对照试验虽然显示柠檬可以治愈坏血病,但他对结果的解读和提出的治疗方法却存在缺陷,这说明即使是科学实验也可能存在误判。 Anna Tuschinski: 坏血病的一个令人不安的症状是旧伤口的重新裂开,这让人联想到过去,也说明了缺乏维生素C对人体胶原蛋白合成的影响。 Andy Hunter-Murray: 青柠虽然酸度更高,但维生素C含量低于柠檬,而且维生素C容易被铜、阳光和高温破坏,这些因素都导致了英国海军对坏血病治疗方法的误解。 James Harkin:
