有的人才40出头就记忆力减退,精力和体力自然一年不如一年;但有的人七八十岁仍精力旺盛、耳聪目明,对生活与未来仍然充满信心。这说明衰老虽是不以人的意志为转移的客观规律,但若注意影响人的寿命的相关因素,推迟和延缓衰老进程,是完全可行的。运动科学家通常认为,长寿与遗传基因有关,但是芬兰科学家进行的最新调查表明,经常运动的人早死的危险性比不运动的人低56%,偶尔运动的人死亡的危险性也要比久坐不运动的人低1/3。通过对双胞胎的对比研究则进一步证明,要长寿,运动比基因更重要。饮食最近,不同国籍的一些科学家在“饮食营养对寿命影响的细胞和分子学基础”专题座谈会上,从不同的角度,以大量动物实验中取得的证据论证了限制饮食可以达到延年益寿的目的。限制饮食的内容包括每日食盐不超过6克;食用油以植物油为主,并以每天25～30克为宜;新鲜蔬菜水果的摄入每天至少在400克以上;增加摄食含脂肪较少而含蛋白质较多的禽类、鱼、瘦肉等,少吃含胆固醇较高的动物内脏;以谷类为主食,做到粗细搭配,增加豆制品食物;少吃糖果、糕点;少饮或不饮酒。
Some people have a memory loss in their early forties, and energy and physical strength are naturally inferior to one year in a year. However, some people in their 70s and 80s are still energetic and confident, and are still full of confidence in life and in the future. This shows that although aging is an objective law that does not depend on human wills, it is perfectly feasible to delay and delay the process of aging if we pay attention to the factors that affect the longevity of human beings. Exercise scientists generally believe that longevity is genetically related, but recent surveys by Finnish scientists show that those who exercise regularly have a 56% lower risk of premature death than those who do not, and people who exercise occasionally have a greater risk of dying than those who exercise sedentary 1/3 of those who do not exercise. By comparing the twins is further proof that to live longer, exercise more important than the gene. Diet Recently, some scientists of different nationalities demonstrated that limiting diet can achieve longevity from a different perspective, based on the evidence obtained from a large number of animal experiments at a special symposium entitled “The Basis of Cellular and Molecular Science on the Impact of Dietary Nutrition on Life Spans” purpose. Restrictions on diet include daily salt does not exceed 6 grams; edible oil mainly vegetable oil, and daily 25 to 30 grams is appropriate; fresh fruits and vegetables intake at least 400 grams per day or more; increase the intake of fat containing less Containing more protein poultry, fish, lean meat, eat less high cholesterol containing animal offal; to cereal as the staple food, with the thickness of the mix, increase soy food; eat less candy, cakes; drink less or drink alcohol.
