新奇事件簿 西兰花和鳄梨延缓衰老

Help may be at hand for those of us who want to keep the wrinkles and grey hair at bay and slow down the process of aging. New research suggests that eating green vegetables can ward¹ off the signs of aging. Researchers say that broccoli², cabbage and avocado in particular contain a compound that helps slow down the rate at which we age. The key compound, present in green fruit and vegetables, is called NMN. It helps slow down the physical signs of getting old. Scientists say NMN can also rejuvenate³ the metabolism⁴. It helps replenish⁵ levels of energy production in our body that deteriorate⁶ as we age. It also helps reduce weight gain and the deterioration⁷ of vision.

想要让皱纹和白发远离我们，延缓衰老过程，方法就在身边。一项最新研究发现，吃绿色蔬菜可以预防衰老。研究人员表示，特别是西兰花，卷心菜和鳄梨含有一种延缓衰老速度的化合物。这种至关重要的化合物名为NMN，存在于绿色水果和蔬菜中，帮助延缓衰老的迹象。科学家表示，NMN可以促进新陈代谢，帮助补充体内能量水平，破坏衰老过程。还可以降低体重，减缓视力衰退。

The research was conducted by scientists at the Washington University School of Medicine in the USA. Researcher professor Shinichiro Imai said: "We have shown a way to slow the physiological⁸ decline that we see in aging mice. This means older mice have metabolism and energy levels resembling that of younger mice." Professor Imai said tests on mice showed that NMN reduced typical signs of aging, including a decline in the strength of skeletal muscle, poor liver function, lower bone density⁹ and weakening eyesight. The reason our metabolism changes over time and leads to reduced energy levels has baffled scientists for decades. This latest research casts new light on this mystery.

这项研究由美国华盛顿大学医学院的科学家进行。研究员Shinichiro Imai教授表示：“在不断衰老的老鼠身上，我们发现了一种减缓生理衰退的方法。这意味着较老的老鼠的新陈代谢和能量水平类似较年轻的老鼠。”Imai教授表示，对老鼠进行的试验表明，NMN延缓特定的衰老迹象，包括骨骼肌力量的衰退，肝功能弱化，骨密度降低和视力衰弱。新陈代谢随着时间改变导致能量水平降低的原因已经困扰了科学家几十年的时间。最新的研究为这个奥秘提供了新的视角。
