Re: Liver/Iodine any thoughts? +update

i have given blood off and on over the years. two things i noticed. one, there were a lot of old men there who were faithful and had the gallon pins to prove it. the other was that when i gave blood i felt better, more energetic.

I've read that giving blood improves insulin sensitivity. Something to do with reducing iron stores reduces free radical damage. Centarians all had one thing in common, low insulin levels. If cells are responsive to insulin, there doesn't need to be elevated insulin floating around. Little to no insulin resistance would keep insulin low, or some genetic anomaly.

bleeding is an excellent way to get rid of toxins. women spend half their lives doing it monthly. take a woman athlete under 7% body fat and she will lose a lot of breast mass and her periods will be almost non-existent.

Bleeding, at least to me, is a great way to lose iron stores that are oxidative. I can't imagine toxins being very picky, but I can imagine losing some as a byproduct of blood donation. If switching to a clean diet and clean living, then donations would eventually help clean out the old unclean diet/life. Women with low body fat would have a change in physiology to compensate for low reserves. Can't have babies on low reserves. Body has safety mechanisms built-in, not all are fail-proof.

my theory is that heavy flow is the body taking advantage of a way to expel toxins. fasting, flushing and cleansing are the key.

funny, you dont see a lot of old women giving blood. these old men? i dont think they are being that altruistic. i think they are getting something out of it. they actually feel physically better by giving blood. an occasional orange juice fast would accomplish the same thing.

i also think this is one reason why women tend to outlive men - a lighter burden of lifetime toxins stored in the body.

Often, we have partial answers to the reasons why certain things are the way they look like they are. While I believe you're right to an extent, another reason women tend to outlive men could be due to higher antioxidant levels, primarily estrogens. What do you think?

In the UCI study, Dr. Vincent Procaccio of the Center for Molecular and Mitochondrial Medicine and Genetics and colleagues discovered estrogen receptors in vascular mitochondrial cells. To see how mitochondria functioned with deficient estrogen levels, they removed the ovaries from test rats, which suppressed any hormone influence, and identified a significant increase in radical oxygen molecule levels and a decline in the capacity for mitochondria to produce energy. In rats treated with doses of estrogen, however, vascular mitochondria produced energy more efficiently with lower amounts of damaging free radicals.

The hormone estrogen, (estradiol) provides natural antioxidant properties because it increases the expression of antioxidant enzymes and decreases troublesome NADPH oxidase enzyme activity and superoxide production. Estrogens have a phenolic hydroxyl group at position 3 and a methyl group at position 13. The presence of this phenol group gives estrogen its antioxidant property by neutralizing oxygen free radicals. The estrogens estriol and estradiol confer significant antioxidant activity.
