|Vacuums can buy happiness.|
Now, I just got our Nilfisk central vacuum installed the other day, and I'm starting to understand the infatuation with vacuuming. It's become my favourite household chore to do. :)
I just want to cuddle my Nilfisk, just like the woman in the ad with her Hoover.
Anyway, enough domestic talk... this recently published study adds weight to the evidence showing lutein and zeaxanthin can reduce the risk of age-related cataract.
Oxidative stress (free-radical damage) plays an important role in cataract formation. Previous studies have shown that long-term dietary intake of two key antioxidants (lutein and zeaxanthin) may decrease the risk of age-related cataracts.
The aim of this study was to examine whether blood concentrations of lutein and zeaxanthin are related to age-related nuclear cataract in an elderly population. Results showed that those in the highest tertiles (upper one-third) of plasma concentrations of lutein and zeaxanthin had 42 and 41 % lower risks of cataract, respectively, compared with those in the lowest tertiles (lowest one-third).
These days, most people think "lutein" when they think eye health. What's great is that most lutein supplements naturally contain a little zeaxanthin. So you usually get both with just one product. However, there is also newer research suggesting zeaxanthin has its own benefits, so keep an eye out for more research on zeaxanthin specifically.
Here are a couple other posts where I've covered lutein and eye health...
