According to new US research filling up on leafy green vegetables could be a factor in keeping your brain healthy later in life, thanks to a nutrient called lutein. Carried out by the University of Illinois, the researchers set out to see if there was a notable difference in cognitive function between younger and middle-age participants with higher and lower lutein levels.
美国的新研究表明:多吃绿叶蔬菜可能会保持你的大脑健康,而这得归因于一种叫做叶黄素的营养物质。伊利诺伊大学的研究人员开展了该项研究,他们想要观察有较高叶黄素水平的年轻受试者和较低叶黄素水平的中年受试者之间的认知功能是否存在明显差异。
Most previous studies have looked at lutein levels in older adults, after there has already been a period of cognitive decline, however the new study recruited 60 participants aged 25 to 45.
先前的大多数研究只观察了老年人的叶黄素水平,而他们的认知功能本就有所衰退,这项新研究招募了60位25至45岁的受试者。
"As people get older, they experience typical decline. However, research has shown that this process can start earlier than expected. You can even start to see some differences in the 30s," said Anne Walk, first author of the paper. "We want to understand how diet impacts cognition throughout the lifespan. If lutein can protect against decline, we should encourage people to consume lutein-rich foods at a point in their lives when it has maximum benefit."
