摄入富含多胺的食物能够延缓果蝇因年龄引起的记忆力下降,10月《自然-神经科学》上的一项研究得出该结论。很多食物都含有多胺,研究证明,多胺会随着人年龄增大而自然减少,此外,其对其他模式生物的寿命也有促进作用。此项最新研究则进一步证明增加饮食中的多胺能够帮助延缓与年龄相关的记忆力减退。大多数器官利用多胺调节细胞的生理过程比如细胞存活和细胞繁殖。哺乳动物细胞自身能够合成多胺--虽然目前相关的原始分子机制几乎 Ingestion of foods rich in polyamines can delay memory loss in fruit flies as a result of age, a study in the October issue of Nature - Neuroscience came to this conclusion. Many foods contain polyamines, studies have shown that polyamines naturally decrease as people age, in addition, it also contributes to the life of other model organisms. This new study further proves that increasing dietary polyamines can help delay age-related memory loss. Most organs use polyamines to regulate cellular processes such as cell survival and cell proliferation. Mammalian cells are themselves capable of synthesizing polyamines - although the current underlying molecular mechanisms are almost
