[维生素C]维生素C有哪些作用？哪些表现提示你维生素C摄入不足？( 二 )
视力丧失
如果你患有老年性黄斑变性(AMD) ， 没有维生素C、其他抗氧化剂和某些矿物质 ， 病情可能会恶化得更快 。 从食物中获取足够的维生素C可能有助于预防白内障 ， 但我们需要更多的研究来更好地理解这一关系 。
坏血病
在18世纪以前 ， 这种潜在的致命疾病曾是海员的一大难题 。 今天 ， 这种情况相对少见 ， 但如果你每天只摄入10毫克或更少的维生素C ， 就有可能发生 。 坏血病患者还会出现牙齿松动、指甲开裂、关节疼痛、骨质疏松和体毛螺旋状等问题 。 当你补充维生素C时 ， 症状会在一天内开始好转 ， 通常会在3个月内治愈 。
