由于接近最高寿命人数不断增加,因此营养状态在老人的体质方面起着重要作用。用动物实验探索可能延长寿命的营养因素是十分有意义的。衰老与营养的关系衰老过程是一个还不太清楚的复杂现象,因此难以确定。人们已开始认识到衰老是一种至少起自胎儿直至死亡所发生的进行性生理学、细胞、生物社会、文化和心理的改变的概念。 Nutritional status plays an important role in the physical well-being of the elderly as the number of people near the highest lifespan continues to increase. Using animal experiments to explore nutritional factors that may prolong life is of great interest. The relationship between aging and nutrition The aging process is a complex phenomenon that is still not clear, so it is difficult to determine. People have come to recognize that aging is a concept of progressive physiology, cell, biological society, culture, and psychology that occurs at least from the fetus to death.
