Yeah, that was a lesson on too much of a good thing. It was actually during a mandatory physical for NASA (maybe they wanted to put me up into space), otherwise I never would have discovered it.
I just wasn't getting enough n-6's, but tons of flax and fish oil. I supplemented with Olive oil, which is largely monounsaturated, not omega 6 (NOTE:n-6 =omega 6).
The tests revealed that my cholesterol was high (total was okay but HDL was low and LDL high), and my triglycerides were abnormally low. This freaked me out and I even posted a "WTF?!" on the board. A friend of mine, who's doing research in the area, told me that a fatty acid imbalance, such as mine, can cause cholesterol problems.
To this day I still don't know how triglycerides can be "too low".
Of course this ended my self-experimentation with fats (and you can learn from my mistake).
BTW-Nice avatar, yet again.
