Here are foods that may improve your
memory, if you can remember to eat
them. You might notice that many of the
foods on this list are red or purple in col-
or. That's because the phytochemical that
colors them, anthocyanin, is the same
phytochemical that's good for your brain.
Blueberries:
Blueberries
have been shown in numer-
ous studies to do wonderful
things for memory and the
brain in general. Old rats
that were fed blueberries scored the same
as young rats on memory tests. Blueberries
contain anthocyanin, a known memo-
ry-boosting phytochemical. They also con-
tain many other phytochemicals that may
contribute to healthy brain function.
Apples:
Apples contain
high levels of quercetin, an
antioxidant that has been
shown in recent studies to
protect against Alzheimer's
disease. Although it is also present in the
flesh, the most quercetin is found in the
skin. Red apples also contain anthocyanin
in their skins.
Spinach:
One study found
that feeding rats spinach
prevented and even reversed
memory loss. This may be
due in part to its high folic
acid content, a nutrient that is believed to be
protective against Alzheimer's disease and
age-related memory loss. Just a half-cup of
cooked spinach provides two-thirds your
daily requirement of folic acid.
Onions:
Red onions con-
tain anthocyanin and quer-
cetin. Yellow and white on-
ions also contain good
levels of quercetin. In In-
dia, where onions are an important staple,
onions have been used as a folk remedy to
boost memory for centuries.
Broccoli:
Broccoli con-
tains quercetin. It's also a
good source of folic acid.
Red Beets:
Beets are a
good source of anthocyan-
in and folic acid.
Grapes Red,
purple, and
black grapes all contain
quercetin and anthocyanin.
Red wine also contains good
levels of these phytochemi-
cals, but overindulging in red wine may ne-
gate the benefits so keeping consumption
to one glass per day may be wise.
Cherries:
Another red
food that is a good source
of anthocyanin.
Eggplant:
Eggplant is a
great source of anthocy-
anin. It also contains
nasunin, an antioxidant
that protects the lipids in
brain cell membranes.
Rosemary:
Researchers
have found that the car-
nosic acid in rosemary is
neuroprotective and may
play a role in the preven-
tion of Alzheimer's disease and other neu-
rodegenerative brain disorders. One study
even found that just the scent of rosemary
improved the memories of office workers.
Green Tea:
You've prob-
ably heard about its antiox-
idant power, but green tea
has also been shown to help
reboot your memory.
Almonds:
Almonds are
an excellent brain food be-
cause they contain a pro-
tein component that boosts
production of a nerve
chemical shown to enhance memory.
Dark Chocolate:
Varieties of dark chocolate
that are comprised of at
least 70-percent cocoa con-
tain flavanols that increase
blood flow to the brain.
Extra-Virgin Olive Oil
This type of olive oil contains
a chemical called hydroxyty-
rosol that tends to increase
messages to the brain and
improves your memory.
Foods That Boost Memory
Smart Fat Choices Protect Your Brain:
Eating fish, olive oi
l
and nuts instead of red meat
and butter might be a menu
plan for protecting your
memory. Besides calories, a
key
difference
between
those dietary choices is the type of fats they
contain. Fish, especially salmon and other fat-
ty fish, are high in omega-3 fatty acids, a type
of polyunsaturated fat. Olive oil contains the
highest percentage of monounsaturated fats
among common oils.
Nuts
are excellent sources
of healthy mono- and poly-
unsaturated fats and may
also contain the plant variety
of omega-3s. Red meat, but-
ter and other foods high in
animal fats, on the other hand, are sources of
saturated fat--the primary culprit in un-
healthy cholesterol levels.
Smart fat choices have long been known to
be important for protecting your heart. But
increasingly scientists are discovering that the
right fats can also protect your brain--while
too much saturated fat can increase your risk
for cognitive impairment.
