Acetaldehyde (systematic name ethanal) is an organic chemical compound with the formula CH3CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl). It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry. Acetaldehyde occurs naturally in coffee, bread, and ripe fruit, and is produced by plants. It is also produced by the partial oxidation of ethanol by the liver enzyme alcohol dehydrogenase and may be a contributing factor to hangovers from alcohol consumption. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke.[4] Consumption of disulfiram inhibits acetaldehyde dehydrogenase, the enzyme responsible for the metabolism of acetaldehyde, thereby causing it to build up in the body

So it would be very hard to avoid AH....but look at what it does to us:

1. It alters red blood cell structure. It has been known since 1941 that AH easily combines with red blood cell membrane proteins to convert the red blood cells into a "time-release capsule" for AH, releasing the AH in the body far from the site where it attached to the red blood cell.

2. reduces ability of red blood cells to accept, hold, and transport oxygen. Anyone tired?

3. decreases ability of the protein tubulin to assemble into microtubules, this means the tubule cannot: (1) provide structural support to the neuron (2) transport nutrients and biochemical raw materials made in the cell to the dendrites (when the dendrites don't get their nutrients, they die off just like in Alz. and alcoholism).

4. Induces a B1 deficiency/depletes B1. B1 is known as the "nerve vitamin", it is so critical to nerve health. How does AH do this? AH combines with B1 and depletes it. Even a moderate B1 deficiency results in Wernicek-Korsakoff syndrome:
mental confusion
poor memory
poor neuromuscular coordination
visual disturbances

5. By depleting B1, AH also creates a deficiency of acetylcholine, a neurotransmitter critical for memory and learning:

"In a classic experiment reported in 1942, R.R. Williams and colleagues found that even mild B1 deficiency in humans continued over a long period of time (the experiment ran six months) produces symptoms including apathy, confusion, emotional instability, irritability, depression, feelings of impending doom, fatigue, insomnia, and headaches, all symptoms of less-than-optimal brain function." And that was only six months.

6. B1 is also necessary for the production of ATP....insufficient B1 = insufficient ATP/fatigue.

Has anyone dealt with trying to reduce/eliminate acetaldehyde in their body? If so, what did you do?
