Can eating eggs prevent dementia?

A research team based at Tufts University near Boston is set to begin a study that will look at the effect of egg consumption on cognitive function in people over the age of 50. Researcher expect to prove that egg consumption is beneficial to neurological health. The focus of the study will be on lutein and zeaxanthin which are found in egg yolk. These two carotenoids help filter out detrimental blue wavelengths of light and are also antioxidants, which helps to protect against macular degeneration and cataracts. Previous studies have pointed towards eggs increasing serum lutein concentrations in older adults. The scheduled study will involve a placebo controlled trial that will last 6 months and study participants will receive either two eggs or four ounces of egg substitute daily and will be over the age of 50. Both women and men will be involved in the study.
