Fishy keys to
health

Students at Cal
State Long Beach may do well on their final examinations after
eating a good amount of fish.
In Japan, where
many people eat fish in their everyday meals, researchers
at Osakana Health Food Conference in Osaka and other dietetics
centers have been studying the fatty acids that only marine
products contain and the benefits that the fatty acids can
bring humans.
The fatty acid
to pay attention to is docosahexaenoic acid (DHA). It has
been proved that DHA does help people to be quick on the uptake
and improves the abilities to memorize.
The research shows
this is because DHA has effects of helping the growth of the
brain cells, softening the cells and quickening the speed
of information communication.
Popular fish that
contain DHA are mackerel, sardines, saury and tuna. Human
bodies will absorb DHA well when they eat these fish raw,
according to the research.
"My friend and
I were thinking about going to eat sushi after the final,
but I think we should better go before the final comes," said
Lynn Saito, a CSULB junior majoring in computer science.
Fish also contain
other materials that can bring us great benefits.
For instance, eicosapentaenoic
acid (EPA), another fatty acid found in fish, will expand
blood vessels and lowers blood pressure, and can prevent humans
from getting cerebral or cardiac infarctions. EPA reduces
the amount of fatty tissues in the blood and also prevents
people from getting thrombuses, which are fibrous clots that
form in and obstruct the blood vessels or form in one of the
chambers of thought.
Also, the iron
fish contains is hem iron, and it is very effective for people
who are anemic because human bodies can easily absorb the
hem iron with greater ease than other irons.
Moreover, a good
quality of protein found in fish reduces the amount of cholesterol
in blood and reduces the extra amount of salt in the body,
then prevents humans from getting high blood pressure and
apoplexies or strokes.
Finally, people
who are irritated or under the stress are recommended by the
researchers to eat fish because it contains rich amounts of
calcium and vitamins, which helps human bodies to absorb calcium.
The 17 years of
study at the National Cancer Center in Japan shows people
who eat fish everyday live five years longer than the people
who rarely eat fish.
It's a good time
for students to consider their dietary habits and get over
the hard situations of final exams under the best conditions
possible.
