Hi Elaine

 

Did you ever read: http://www.asthmaworld.org/Essential_Fatty_acid.htm

??????

I wonder where Colin Price gets his paychecks?? I'll bet drug companies

have some influence on him.

Harvard Heart Letter

November 2001

 

Go Fish: a Good Choice for Preventing Strokes

There's little doubt that fish is a healthy food. It's low in

artery-clogging saturated and trans fats. What's more, fatty, cold-water

fish such as salmon or mackerel are high in omega-3 fatty acids, which are

thought to help inhibit the formation of blood clots in arteries. Although

the evidence clearly suggests that eating fish may lower your chances of

having a heart attack or developing an abnormal heart rhythm, the connection

with stroke is still coming into focus.

 

A large study of dietary habits and health, published earlier this year as

part of the ongoing Nurses' Health Study, has helped clarify this link.

During the 14 years they were studied, 574 of the almost 80,000 women had a

stroke. Most (46%) were thrombotic strokes, which occur when a clot blocks

the flow of blood in an artery leading to or inside the brain (see figure).

Another 32% were hemorrhagic strokes, caused by bleeding inside the brain.

Seven percent were the result of emboli - clots carried to the brain from

elsewhere in the body.

 

Women in the Nurses' Health Study who ate fish at least twice a week were

about half as likely to suffer a thrombotic stroke as women who ate fish

less than once a month. (Journal of the American Medical Association, 2001,

Vol. 285, No. 3, pp. 304-12.) This finding is in line with earlier data

showing that eating fish reduces the chances of having a heart attack, since

flow-blocking clots are a prime cause of heart attacks. But the results also

put the stroke-related benefit of eating fish into perspective, showing that

it is smaller than the benefit of taking aspirin and may be completely

overshadowed by that effect. Among women who regularly took aspirin, the

amount of fish eaten had little or no effect on thrombotic stroke. In other

words, if you take aspirin regularly, eating fish won't give you extra

protection against stroke. But it may have other health (and gastronomic!)

benefits, and certainly won't do you any harm.

 

Fish Oils May Hold the Key

Nurses' Health Study investigators also wanted to learn whether omega-3

fatty acids were an important ingredient in the apparent ability of fish to

prevent strokes. So they estimated how much of these fatty acids the women

ate each day during the 14-year study period and compared the stroke rates

of women with high and low intakes. Those at the high end were less likely

to have had any kind of stroke. In particular, women whose diets included

the most omega-3 fatty acids and who didn't take aspirin on a regular basis

were half as likely to have had a thrombotic stroke as those whose omega-3

fatty acid consumption was the lowest.

 

What works for thrombotic stroke need not necessarily work for hemorrhagic

stroke. Indeed, there's some evidence that eating a lot of fish - and thus

getting hefty doses of omega-3 fatty acids - might slightly increase the

risk of bleeding strokes. For example, Eskimos living in Greenland, who take

in 50 to 100 times as much omega-3 fatty acids as the average American, have

a higher risk of hemorrhagic stroke. But no such increased risk was seen in

the Nurses' Health Study, even among women who ate fish five or more times a

week.

 

Benefits from Fish Don't Necessarily Mean Benefits from Fish Oil

The results of this study could reflect other factors common to the women

who ate the most fish, such as exercising more, smoking less, or eating more

fruits and vegetables. They could also reflect the ability of omega-3 fatty

acids to prevent platelets in the bloodstream from clumping together.

Aspirin is thought to prevent - and treat - heart attacks the same way.

 

This well-designed study lends support to dietary guidelines that recommend

eating more fish. It also allays fears that eating fish several times a week

might lead to hemorrhagic stroke. But it doesn't give us a green light to

take fish-oil supplements instead of eating fish. So far, there is little

good evidence that these supplements offer any further protection against

cardiovascular disease, and they could contain too high a dose of omega-3

fatty acids - especially for anyone taking blood-thinning medications such

as Coumadin. Fish oil supplements can also make breathing problems worse for

people with asthma.

Most of the studies have been done with fish oil capsules. This conclusion is

not supported by the current data. As

for the bleeding, you would need to take massive doses of EPA, about 20 times

more than the recommendations of ~ 0;6 g

EPA + DHA. EPA in the membrane of the heart muscle actually stops arrhythmia

and it does not matter there it comes

from. Also EPA improves blood vessel elasticity and will reduce hemorrhagic

(burst blood vessel) events. The only

thing asprin does is to lower blood clotting (by reducing Omega 6 AA derived

eicosanoids) but this is actually caused by

having too much Omega 6 AA and not enough Omega 3 EPA in the membranes of the

red blood cells. Again using KIM to get

your Omega ratios in the green will fix this.

 

With KIM there is no reason to guess if you are getting too much or not enough

EPA & DHA. KIM is an excellent tool to

improve your health.

Again this is not supported by the data. Several studies have found some relief

from the use of EPA and some not. I

have not read of ANY showing worst problems.
