Re: omega 6 & 3, parent essential oils.

Hi Sumner,

> pardon my ignorance, but what makes krill oil better than fish oil?

Well apparently it has a high ORAC value, which has no demonstrated

phsyiological significance but is generally taken to mean something is

high in " antioxidants, " so it is possible that it would be less likely

to raise the risk of lipid peroxidation within your body although to

my knowledge this has not been demonstrated. Also, Mercola says that

it has a greater proprotion of its PUFA as phospholipids so they are

better absorbed.

Sorry for not explaining myself better before, but, basically:

1) it isn't even true that the " parent " oils are essential in the way

he says; we can make them from other fatty acids found in green

vegetables

2) while he is correct about the " standard " use of the terminology,

the standard use of the terminology is stupid, because the fatty acids

that we NEED are not called essential, and the ones that we have no

demonstrated use for whatsoever ARE called essential, simply because

we (supposedly) cannot make them, whereas the ones we need are not

called essential because we can make them, but only out of the ones we

don't need. So it does not take a scientist to figure out that it

makes much more sense to refer to the ones we need as essential,

especially since, in the absence of the ones we don't need, we can't

make them.

3) there is no evidence whatsoever that the rate of synthesis of

longer-chain " derivatives " has any relation to our " need " for them.

4) the basic logic is completely backwards. Since the 95% of PUFA we

do not need are highly vulnerable to lipid peroxidation and the 5% we

need are also highly vulnerable to lipid peroxidation, we could

consume 20 times less lipids that are highly vulnerable to

peroxidation by consuming the 5% of the " derivatives " instead of the

95% of the " parents. "

Fish oils are not high in vitamin D anyway, so the sunshine isn't a

factor. If you get plenty of salmons, you defintiely do not need fish

oil and should avoid it. Cod liver oil supplies vitamins A and D, and

the A can be useful even if you get lots of sunshine, though if you

get lots of liver, you do not need the A.
