A new study at Tufts University will determine if eating eggs daily reduces your risks of dementia in old age. Egg lovers will rejoice if an egg a day keeps dementia away. Why eggs?
A study published by the American Society of Nutrition in 2012 found the combination of DHA and lutein supplementation improve cognitive functions in elderly participants of the study. Previous studies found that patients with mild dementia had lower concentrations of lutein in their brains compared to patients without symptoms of dementia.
Based on the results of previous research connecting lutein with mental health, Tufts researchers chose eggs for their study, because eggs have a high concentration of two related antioxidants, lutein and zeaxanthin. Both are found in high concentrations in healthy brains, along with DHA. DHA is the omega-3 fatty acid, which is one of the primary structural components of our human brain.
If eggs prove to improve brain function in the elderly, it will be a relatively cheap source of nutrition to help reduce their risks of dementia.
Eggs and yellow corn have the highest percentage of both lutein and zeaxanthin, but eggs are the best source of both antioxidants together. Yellow corn has a higher percentage of lutein, while orange peppers have a high percentage of zeaxanthin. Both antioxidants can also be found in kiwi fruit, grapes, spinach, zucchini and other squash.
DHA is found in cold water, fatty fish like wild salmon, sardines, herring and tuna.
Eating fatty ocean fish along with eggs and yellow corn on a bed of spinach, and kiwi fruit for dessert, may prevent the onset of dementia, if the new study at Tufts University determines eggs improve cognitive function in the elderly. You can enjoy a relatively inexpensive and delicious meal, and stay mentally healthy throughout your old age.
