过量吃糖不但容易造成龋齿,同时影响视力。食糖在体内代谢需要维生素B_I,多吃糖可导致维生素B_1缺乏,容易出现视神经传导障碍,发生视神经炎,尤其是球后神经炎,因而使视力下降。同时,糖在体内可转化为酸性物质,与钙中和反应,使体内钙大量消耗,促使眼内膜的弹力减退,眼球伸长,引起轴性近视。所以孩子不宜长期过量吃糖。

Excessive sugar is not only easy to cause dental caries, while affecting vision. Sugar metabolism in the body need vitamin B_I, eat more sugar can lead to vitamin B_1 deficiency, prone to optic nerve conduction disorders, the occurrence of optic neuritis, especially after the ball neuritis, thus reducing vision. At the same time, sugar in the body can be transformed into acidic substances, and calcium and the reaction, so that a lot of consumption of calcium in the body, prompting the loss of elasticity of the endometrium, eyeball elongation, causing axial myopia. So children should not long-term excessive sugar.
