点点英语论坛读经济学人文章中的小问题

大家好，老师们好。我是一个艺术生，英语学习方面还比较浅，下面这段也是我从经济学人文章上摘抄的，有的地方不明白，请各位老师指点。 That suggests, among other things, the value of a diet rich in berries. These have been shown to have strong antioxidant effects, though only a small number of their constituents have been evaluated in detail. One group that has been evaluated, the polyphenols, has been shown in rodents to reduce oxidative damage and to boost the ability to learn and retain memories. In particular, these chemicals affect changes in response to different types of stimulation in the hippocampus (a part of the brain that is crucial to the formation of long-term memories, and which is the region most affected by Alzheimer’s disease). Another polyphenol, curcumin, has also been shown to have protective effects. It reduces memory deficits in animals with brain damage. It may be no coincidence that in India, where a lot of curcumin is consumed (it is the substance that makes turmeric yellow), Alzheimer’s disease is rarer than elsewhere.
我的问题是印度的老年痴呆症发生率到底是高还是低呢，前面好像说高，后面说的低，有点看不明白。

Another polyphenol, curcumin, has also been shown to have protective effects(具有保护作用). It reduces memory deficits(降低记忆损失) in animals with brain damage. It may be no coincidence that（...也许不是巧合） in India, where a lot of curcumin is consumed (it is the substance that makes turmeric yellow), Alzheimer’s disease is rarer（少有） than elsewhere. curcumin的消费量很大，Alzheimer比其他地方少见，也许不是什么巧合(言下之意就是与curcumin的食用有关)。

这段其实主要是讲富有果浆的饮食（a diet rich in berries）的价值，后面分别讲到了这种diet中已经检测出来两种益处。其中的一种益处，即是其含有姜黄素（curcumin），它的功用在于能减少有着大脑损伤动物的记忆缺失。而后面讲到在印度，正是由于大量的姜黄素被摄入，老年痴呆症也就比其他地方更少一些。
