You want to increase your overall health and energy level. You want to
prevent heart disease, cancer, depression and Alzheimer's. Perhaps you also
want to treat rheumatoid arthritis, diabetes, ulcerative colitis, Raynaud's
disease and a host of other diseases. One of the most important things you
can do for all of these is increase your intake of the omega-3 fats found in
fish oil and cod liver oil, and reduce your intake of omega-6 fats.
These two types of fat, omega-3 and omega-6, are both essential for human
health. However, the typical American consumes far too many omega-6 fats in
their diet while consuming very low levels of omega-3. The ideal ratio of
omega-6 to omega-3 fats is 1:1. Our ancestors evolved over millions of years
on this ratio. Today, though, our ratio of omega-6 to omega-3 averages from
20:1 to 50:1! That spells serious danger for you, and as is now (finally!)
being reported throughout even the mainstream health media, lack of omega-3
from fish oil is one of the most serious health issues plaguing contemporary
society.

The primary sources of omega-6 are corn, soy, canola, safflower and
sunflower oil; these oils are overabundant in the typical diet, which
explains our excess omega-6 levels. Avoid or limit these oils. Omega-3,
meanwhile, is typically found in flaxseed oil, walnut oil, and fish.

By far, the best type of omega-3 fats are those found in that last category,
fish. That's because the omega-3 in fish is high in two fatty acids crucial
to human health, DHA and EPA. These two fatty acids are pivotal in
preventing heart disease, cancer, and many other diseases. The human brain
is also highly dependent on DHA - low DHA levels have been linked to
depression, schizophrenia, memory loss, and a higher risk of developing
Alzheimer's. Researchers are now also linking inadequate intake of these
omega-3 fats in pregnant women to premature birth and low birth weight, and
to hyperactivity in children.

I did not know about omega-6 oils. WW considers canola, safflower and
sunflower oil to be healthy oils and we are supposed to have 2 teaspoons of
these or flaxseed oil a day. I guess I am going to switch to flaxseed. I
already take flaxseed capsule and will switch my salad oil from canola to
flaxseed as well. I wonder what type of fat olive oil is??

I suddenly feel like everywhere I turn people are encouraging me to eat
more Omega three. Not to be ignorant, but isn't that the thing they
needed to activate on the movie Galaxy Quest that jumps time back 13
seconds? But seriously, I know sardines are high in Omega three, but
yuck! Can't deal with it. Also olives. That sounds good. But what are
the supposed benefits of Omega three and what other ways can I add it to
my diet?
