很多人都知道,大红枣是可以补血的。然而有专家说,红枣中铁的含量少得可怜,还不容易被吸收,所谓“红枣补血”只是个传说罢了。红枣到底能不能补血呢?这主要得看如何定义“血”了。血的概念西医认为血是由红细胞、白细胞、血小板及其他蛋白质、电解质组成的。血之所以是红色,是由于红细胞中含有血红蛋白。铁元素是血红蛋白非常重要的组成元素之一,因此,补血就要补铁。科学测定发现,每100克干红枣的含铁量平均只有2毫克,因此,从西医角度来看,红枣没有多少补血价值。
Many people know that big jujube can blood. However, some experts said that jujube in iron content pitiful, not easily absorbed, the so-called “jujube blood” is just a legend nothing more. Jujube in the end can blood it? This depends on how to define the main “blood”. The concept of blood Western medicine that blood is composed of red blood cells, white blood cells, platelets and other proteins, electrolytes. The reason why blood is red is due to red blood cells that contain hemoglobin. Iron is one of the most important elements of hemoglobin, therefore, it is necessary to make iron supplementation. Scientific tests found that the average iron content per 100 grams of dried dates is only 2 mg, therefore, from the Western point of view, jujube not much blood value.
