Fortunately, your body has mechanisms to reduce the output of OH radical and instead put out the less harmful nitric oxide. Still, though, it seems like for antioxidants to have any effect, they'd have to be at a comparable concentration to other things in your cells that these free radicals might react with.

Thanks for your thoughts, Wookie. My concern is that the scientists have a very crude understanding of how the body works and how it utilizes various forms of nutrients. The article I linked tries to point out that just because something works in a test tube does not mean it will automatically work in the body. That's what they've discovered with antioxidant supplements. In fact, some studies indicate that it is not helpful and is possible harmful.

In 1992, researchers were studying lung cancer and found that the antioxidant beta carotene showed promise against cancer. They recruited 18,000 for a controlled study.


" the researchers pulled the plug two-thirds of the way through after discovering, to their surprise and horror, that those taking supplements were faring worse than the controls."

Also in the 1990s, researchers found that a diet high in vitamin E significantly reduced the incidence of heart disease. However, experiments using vitamin E supplements have been very disappointing. Several of the studies showed no effect and one showed that it caused harm.

In fact, despite good evidence that vitamin E is a powerful antioxidant in the test tube, there is now serious doubt that it acts the same way in the body. "Vitamin E is not an antioxidant. In fact it must be protected against oxidation," says Angelo Azzi, a biochemist at Tufts University in Boston, Massachusetts. He points out that vitamin E exists in eight different forms in nature, all of which function as antioxidants in the test tube. Yet the body only uses one form, alpha tocopherol, which is pulled out of the bloodstream by a highly specialised protein in the liver. All the other forms are excreted. Azzi argues that evolution is unlikely to have gone to such great lengths simply to obtain an antioxidant from the diet. "There are millions of antioxidants," he says.

The conclusion is becoming clear: whatever is behind the health benefits of a diet rich in fruits and vegetables, you cannot reproduce it by taking purified extracts or vitamin supplements. "Just because a food with a certain compound in it is beneficial, it does not mean a nutraceutical [with the same compound in] is,"

I'm still very curious how they came up with the daily requirements for vitamins. Anyone know? I read one article that said it was based on very old data having to do with scurvy. I've no idea if that's true or not.

No, Blarg's in the right thread. There has definitely been politics present in the FDA recommended servings of, say, milk per day.

They tell our soldiers in Iraq that if their urine isn't clear they're on their way to dehydration. I'm sure they have to be very diligent with the heat.

Personally, I'm a human sponge. I fill up my glass with ice water first thing when I get up, last thing before I go to bed, and all day in between. A friend even once had a dream about me chugging gallons of water.

Fish Oil is the one supplement that my doctor recommended I take daily, so I do. In fact, Omega 3 is supposed to be the next big food supplement marketed in everything we buy at the grocery store.

I'm not big into vitamins, (though I did just start taking a daily this past year), or antioxidants, but I know that the Mayo clinic has found that ALA, (Alpha Lipoic Acid), can reverse the symptoms of diabetic nueropathy.

To my knowledge we don't have a med that can do this, (only those that help control the symptoms). Reports I've read from people who have taken ALA say you have to get your blood sugar under control first, then the ALA helps. They've been using it intravenously in Europe for a while. Here you can buy pills over the counter.

Yeah, I'm probably just being poisoned by my own testicles, so it's clouding my thinking.

Ha! As long as it was already mentioned, my first thought was that you must be dehydrated, with all that sweating you do down there.



I'm originally from Illinois, and have family that still farms there. I keep my opinion close to the vest on the subject, but I have always looked at those vast corn fields and marveled at how much of it goes merely to make cows fat.

Merely. lol.

What about the latest diet fad, the first FDA approved diet pill, Alli?

About Alli
Cost: About 60 cents per pill, or $1.80 a day

What it is: Over-the-counter version of the drug orlistat, which blocks fat absorption in the intestines.

What it does: Helps users lose weight by cutting the calories absorbed from fat.

Side effects: Excessive fat passing through the digestive tract can lead to diarrhea, oily stools, upset stomach and flatulence.

Any overweight Loungers considering trying this?

I cry [censored]. I'd wager that by the time that water gets anywhere close to where your body might absorb that 02 (if it even could possibly be absorbed), you'd have belched out all the extra 02.
