一般有关营养的书籍文献记载:在自然界除了新鲜蔬菜和水果等少数食品外,其它食品都很少含有或根本不含有抗坏血酸。然而,海岛渔民长年生活在海上,他们终日以各种鱼类佐食,不独在海上吃不到新鲜蔬菜,在返航回家后也没有吃蔬菜的习惯,但是没有坏血病存在的迹象。因此,弄清渔民维生素C的营养问题,不仅对平时驻岛部队的食品供应,对战备军粮的制备,而且对有关维生素C营养知识的进一步掌握等等,都有着非常重大的意 In general, books on nutrition have documented that in nature there is little or no ascorbic acid in the food, except few foods such as fresh vegetables and fruits. Island fishermen, however, have been living in the sea for many years. They all day long feed on various kinds of fish. They can not eat fresh vegetables at sea and have no habit of eating vegetables after returning home. However, there are no signs of scurvy. Therefore, to clarify the nutrition of fishers’ vitamin C is not only of great significance to the food supply of the troops stationed in the island, the preparation of the readiness military supplies, but also to the further mastery of the nutrition knowledge about vitamin C.
