Healthy greens (preferably organic) contain folate, calcium, and other nutrients that support bone health and help prevent age-related eye problems.
Diets high in cruciferous veggies, such as broccoli and cabbage, help reduce memory loss and cancer!
I confess to not taking calcium supplements! but there isn't a day that goes by that I don't have a HUGE portion of dark leafy greens or cruciferous veggies!
