It is important to note that acetaldehyde scavenging does not repair damage done by previous acetaldehyde exposure. It merely prevents further damage from additional acetaldehyde being released by yeast metabolism -- something that happens whenever the yeast is fermenting pyruvate from carbohydrates in the diet. Sugar is a rapidly metabolized low molecular weight carbohydrate.
By reducing the cumulative stress incurred from chronic acetaldehyde exposure, an acetaldehyde scavenger allows the body's own healing processes to function more effectively. As well the acetaldehyde scavenger must be present in the areas of yeast colonization to be useful. Hence, there may be some latency time between the commencement of such a protocol and actual remission of symptoms. Some chronic conditions may have taken years to develop. It is not unreasonable to not see definitive results until after one or two months on the protocol. This is why it is so critical that the acetaldehyde scavenging substance have no side effects of its own so that it may be continued indefinitely if desired.
