现在没有谁会不知道,铁是维持我们正常生理活动、必不可少的一种元素了,而且还是需要补的。因为我们每天都在流失铁。每天,铁都在通过你能够想象到的所有途径,匆匆离开我们。运动、出汗、排尿、大便、月经、外伤出血、剪指甲以及毛发脱落等等,都会造成铁的流失。正常成年男性平均日流失铁11.5毫克;女性平均日流失铁约2毫克。作为一个成年人,我们都可以从每天的食物中,获取足够的铁来补充这些流失的部分。但在某些情况下,当体内的铁流失过多时,那我们就需要额外的补铁了,最典型的就是青春发育期。在这段时期,身体除了要维持正常的生理活动外还要长大。研究表明青春期的人体,每天消耗掉的铁可以达到18毫克。当铁大量流失,却又得不到有效的补充时,各种缺铁症状就会显现出来,可以归结为以下几种:体能下降,易疲劳要提供能量就需要消耗养分和氧;而养分和氧是靠血液输送的。真正承担起这一任务的是血液中红细胞中的血红蛋白,而铁元素是合成血红蛋白所必需的物质。所以铁缺乏势必影响血红蛋白的合成,而 Now no one will not know that iron is an indispensable element to maintain our normal physiological activities, and it still needs to be supplemented. Because we are losing iron every day. Every day, iron is hurried away from us in all the ways you can imagine. Exercise, sweating, urination, stool, menstruation, traumatic bleeding, nails and hair loss, etc., will cause the loss of iron. Normal adult men lose 11.5 mg of iron per day on average; women lose about 2 mg of iron per day on average. As an adult, we can get enough iron from daily food to supplement these lost parts. But in some cases, when there is too much iron in the body, then we need extra iron, the most typical is the puberty. During this period, the body has to grow besides maintaining normal physical activity. Studies show that adolescents can consume up to 18 milligrams of iron per day. When a lot of iron loss, but can not be effectively added, the various iron deficiency symptoms will be manifested, can be attributed to the following: physical decline, easy to fatigue to provide energy on the need to consume nutrients and oxygen; and nutrients and Oxygen is delivered by the blood. What really takes up this task is hemoglobin in the red blood cells of the blood, which is an essential element in the synthesis of hemoglobin. Therefore, iron deficiency is bound to affect the synthesis of hemoglobin, and
