Basic knowledge
Every kind of nutrition is important in food. Lacking
fat, the same as lacking other nutrition, will cause discomfort.
After digestion, fat is break up into glycerin and various
fatty acids. According to different structure, fatty acid
is divided into saturated fatty acid and unsaturated fatty
acid which contains single-unsaturated fatty acid and
multi-unsaturated fatty acid. According to different location
of the first double bond from methyl, PUSA can be divided
intoω-3 unsaturated fatty acid and ω-6 unsaturated fatty
acid. Like vitamin and mineral elements, ω-3 is necessary
to human body and lacking it will cause disorder of heart
and brain.
The most important two fatty acid inω-3 unsaturated
fatty acid are DHA and EPA. EPA is the English short form
of eicosapentaenoic acid. It can clear garbage in blood
(cholesterol and triglyceride) and its informal name is
bloodashman. DHA is the English short form of docosahexaenoic
acid. It can soften blood vessel, nourish your mind and
improve your eyesight and its informal name is braingold.
☆ Main effect
1. Keep comparatively fluidity of cell membrane to
ensure normal physiological functions of cells
2. Esterify cholesterol and lower cholesterol and
triglyceride in blood
3. Reduce blood viscosity and improve blood microcirculation
4. Improve cell activity, memory and ideation
☆ Taking multi-unsaturated
fatty acid reasonably
ω-3 unsaturated fatty acid is synthesized by hydrophyte
in cold area. The viscus of blue water fishes (wild
Pollock, trout´) that is feed on this plant is rich
in ω-3 unsaturated fatty acid. In 1970, after investigation,
two Danish doctors ensure that less residents of Greenland
have cardiac cerebral vascular disease than that of
Danish mainland. Greenland lies in the Arctic Ocean.
Eskimos in island rely mainly on halieutics and they
like fish. Because of coldness, it is hard for them
to have fresh fruits and vegetables. According to common
medicine sense, more animal fat and less fruits and
vegetables will cause cardiac cerebral vascular disease
and shorten their life. But just the reverse was true.
Eskimos are not only healthy, but it is hard to find
high blood pressure, coronary heat disease, cerebral
apoplexy, cerebral thrombus, rheumatoid arthritis and
so on. It is not a unique instance, but has its counterpart.
The magical phenomenon occurred in Hokkaido of Japan.
Less fisherfolk have cardiac cerebral vascular disease
and the incidence in Hokkaido is only 1/10 of occident-developed
countries. The reason is that they rely on fishes which
are rich in long-bond unsaturated fatty acid.
But most people in daily life cannot eat blue water
fishes like Eskimos. Because of technique of production
and processing, people absorb and utilize few unsaturated
fatty acid in some food. Then human body lack multi-
unsaturated fatty acid and accumulate quantities of
saturated fatty acid. Applying biotechnology of 95 National
Science Important Project charged by CAU, according
to physiologic tendency and nutrition needs of middle
aged and elderly people, Beijing Webly Sci.&Tech.
Development Co., Ltd. developed high nutritious food-Bolile
which has necessary nutrients, like lecithin, multi-unsaturated
fatty acid, vitamin E and many mineral elements. It
is safe, delicious, convenient and has no sucrose. t
is really a functional nutritious food for middle aged
and elderly people.
