A recent study out of Canada's University of Alberta will be good news for people who have made seafood part of healthy aging. Researchers discovered that omega-3 fatty acids commonly found in fish can help stave off age-related vision loss.
Scientists from the school looked at how mice responded to a certain type of omega-3 fatty acid, sometimes referred to as DHA. They discovered subjects that were fed DHA did not experience the accumulation of a certain toxic molecule often associated with vision loss. The researchers paint the results as somewhat of a breakthrough.
"In normal aging, this toxin increases two-fold as we age. But in lab tests, there was no increase in this toxin whatsoever," researcher Yves Sauve said. "This has never been demonstrated before - that supplementing the diet with DHA could make this kind of difference."
Omega-3 is not the only nutrient that may hold potential in protecting one's vision. According to a 2011 study, vitamin D from sources such as fish, dairy and eggs could lower the risk of age-related macular degeneration by as much as 59 percent, ABC News reports.
