人到老年,虽然积累了丰富的知识和经验,但记忆力却呈普遍下降趋势。随着年龄的增长,记忆力减退的程度会越来越明显,有的高龄老人甚至会严重丧失记忆力,形成老年健忘症或痴呆症。老年人记忆减退的主要表现是:对近期发生的事情易遗忘,并常常误事。 如何改善老年人的记忆功能,科学家们做了大量研究,证明食物疗法既切实可行,又简单有效。 一、补充卵磷脂。卵磷脂是大脑脂质中的重要成分,它由甘油、脂肪酸和胆碱组成。卵磷脂被人体消化吸收后可释放出胆碱,胆碱能在血液中形成乙酰胆碱。而乙酰胆碱又是神经元中传递信息的一种最主要的“神经递质”。脑细胞有了乙酰胆碱这种神经递质,感觉和记忆力才得以形成。卵磷脂还能控制脑细胞的死亡,而且还可能 People to old age, although accumulated a wealth of knowledge and experience, but memory generally showed a downward trend. With age, the degree of memory loss will be more obvious, and some elderly people may even seriously lose memory, the formation of amnesia or dementia. The main manifestations of memory loss in the elderly are: the recent events that are easy to forget, and often misleading. How to improve the memory function of the elderly, scientists have done a lot of research to prove that food therapy is feasible and simple and effective. First, add lecithin. Lecithin is an important component of the brain lipid, which consists of glycerol, fatty acids and choline. Lecithin is released by the body after the release of choline, choline can form acetylcholine in the blood. Acetylcholine, on the other hand, is one of the most important “neurotransmitters” in neurons that transmit information. Brain cells with acetylcholine this neurotransmitter, feeling and memory was formed. Lecithin can also control the death of brain cells, but also possible
