It's odd to lump spinach and eggs in the same "healthy food" category, but a recent bout of research concluded that two nutrients found in eggs and spinach can offer blindness protection in the elderly.

Macular degeneration (MD), which affects 1.2 million older Americans, is irreversible and there is little hope of recovery once it has set in. As the saying goes, though, an ounce of prevention can be worth a lot.

In this case, the nutrients known as lutein and zeaxanthin -- which give many fruits and vegetables that yellow color -- may be the ticket for preventing the onset of MD as much as possible. Now, didn't I just see that banana?
