Stop Aging of Blood Vessels: LDL Cholesterol

​Hardening of blood vessels which can result in stroke or heart attack is mainly caused by high cholesterol and high blood pressure.
 
It has been found by recent researches that there are 2 ingredients which prevent and improve high cholesterol and high blood pressure.

Fig. 1 is the cross-section of the blood vessel which path reduced by half due to plaque formed by cholesterol.

The ingredient to decrease cholesterol is a fish with glistening skin
 
Fishes with glistening skin or bluish back such as sardine, mackerel whose oil contains DHA and EPA which smooth the blood and rejuvenate blood vessels. This is actually what a lot of people already know.
 
But it turned out by the latest new research that there was a new fact that fishes with glistening skin stopped the aging of the blood vessel.
 
There is a possibility that eating bluish back fishes will remove plaques blocking the blood vessel and restore the blood vessel to the healthy condition.
 
If LDL cholesterol increases too much in the blood, LDL cholesterol forms a plaque by invading the blood vessel, resulting in hardening of blood vessels. What was believed previously was that increasing HDL cholesterol leaded to decreasing LDL cholesterol accumulating in the blood vessel. That means you have to increase HDL cholesterol to prevent aging of blood vessels.
 
But it has turned out that eating bluish back fish decreases LDL cholesterol without increasing HDL cholesterol.
 
Experiment: Difference of the amount of LDL and HDL cholesterol between people who eat a lot of bluish back fish and people who don’t
 
6 women with the age of 50s to 70s attended the experiment. 3 of them eat bluish back fish 2-4 times a week (Bluish Back Fish) and another 3 of them eat bluish back fish about once in 2 weeks (No Bluish Back Fish).
 
HDL cholesterol (guide line: more than 40 mg/dl)
Bluish Back Fish: 72, 43, 70
No Bluish Back Fish:  54, 79, 48
 
Whether or not eating bluish back fish didn’t make big difference about HDL cholesterol.
 
So what about the age of blood vessels?
Bluish Back Fish: 8-11 years old younger than their actual ages
No Bluish Back Fish: 3-8 years old older than their actual ages
 
What makes the big difference about the age of blood vessels even if their HDL cholesterols are almost the same?
 
We all have different power of HDL cholesterol.
 
According to the latest research, the stronger the power of HDL cholesterol is, the more hardening of blood vessels is prevented.
 
Bluish back fishes have the effect to increase the power of HDL cholesterol.
 
How about the power of HLD cholesterol of the above 6 people?
 
(guide line: more than 0.34)
Bluish Back Fish: 0.38, 0.35, 0.35
No Bluish Back Fish: 0.33, 0.32, 0.33
 
People who often eat bluish back fishes have strong HDL cholesterol and young blood vessels.
 
Why does eating bluish back fishes strengthen the power of HDL cholesterol?
 
It has turned out that a nutrition contained in bluish back fishes strengthens the power of HDL cholesterol.
 
The nutrition is EPA which is rich in the fat of bluish back fishes.
 
EPA strengthens the power of HDL cholesterol and decreases LDL cholesterol accumulating in the blood vessel.
 
HLD cholesterol usually retrieves LDL cholesterol accumulating in the blood vessel and delivers them to the liver, but can’t retrieve all LDL cholesterol.
 
EPA improves the ability of HDL cholesterol to retrieve LDL cholesterol, leading to improvement of hardening of blood vessels.
 
How much EPA should be taken?
 
It turned out that taking 1800 mg of EPA every day leaded to strengthening the power of HDL cholesterol and improving hardening of blood vessels.
 
1800 mg of EPA is equivalent to 2 slices of mackerels (Fig. 2).
 
A canned mackerel in water contains 1860 mg of EPA (Fig. 3).
