Snack On Nuts

"Nuts of all kinds are full of magnesium, a mineral
linked to improvements in short-and long-term memory.
(A handful of almonds or cashews, in paricular, boasts
about 25 percent of your daily requirement.) According
to research from MIT and Tsinghua University in Beijing,
magnesium seems to promote new connections between brain
cells."
