Exercise for Your Eyes

Lutein for more than eye health

The eyes have it–a challenging job staying healthy. Because they have no natural protection from the sun’s rays or the blue rays emitted by electronics like our smartphones and computers, they are subject to large amounts of oxidative stress. The blood flow and health of the neurons connected to the eyes also play a big role in how well we continue to see.

Is it any wonder that age-related macular disease, the leading cause of blindness and vision impairment, can be greatly helped by a hard-working carotenoid that works as an antioxidant known as lutein?*

Besides being greatly important for eye health, lutein may have several other roles for health in the body. It has anti-inflammatory properties, and may support cognitive, immune and cardiovascular health besides the good work it does for the eyes.*

In the following review, doctors linked lutein levels to greater physical activity in adults, postulating that the yellow carotenoid may also help prevent chronic disease:

Doctors reviewed 17 studies that compared lutein levels to physical activity in adults. Studies that measured circulating lutein levels and physical activity found those with the highest lutein levels were 57 percent more active than those with the lowest levels. In several of the studies asking participants to report their diets and physical activity, higher lutein levels were linked to 20 to 600 percent greater levels of physical activity.

Doctors believe it is the antioxidants in lutein that help maintain the integrity of cellular DNA, preventing genetic mutations that can lead to disease, and providing the benefits to physical activity. Physical activity also reduces the chances of developing chronic diseases.

Discussing the findings, doctors said, “If increasing lutein levels, or possibly also the levels of other carotenoids, is able to increase physical activity, this might be useful for improving physical activity to mitigate the chances of chronic disease.” Reference: Nutrients; 2018, Vol. 10, No. 9, 1186

Just another reason to keep moving. And when you do go out and exercise, don’t forget the sunglasses!
