What Is Autism Trying to Teach Us?
August 9, 2007 The rising number of children with autism could be a warning. Genetically, these children may be especially sensitive to some of the tens of thousands of pollutants in our environment.
According to Discover magazine, autism researchers have begun paying attention to the digestive and immune disturbances that accompany the personality aberrations of autism. Autism is probably connected to genetics. That’s “genetics,” not “a gene.” And autism is probably connected to environment. Like most genetic phenomena, it’s a combination of nature and nurture.
Genes often work in teams, like this: All your cells need a certain anti-oxidant molecule. In each cell, gene 1 in the team manufactures the first part of the anti-oxidant molecule. Then gene 2 in the team takes the first part of the anti-oxidant and adds a second part. Then gene 3 adds a third part, and so on until a final gene completes the job. When the anti-oxidant molecule—let’s call it glutathione—is finished, it can start detoxifying poisonous oxygen radicals that result from daily cell work.
Now let’s suppose that one of the genes in the glutathione team is handicapped. Glutathione production slows down. Or the glutathione is defective. Either way, crowds of oxygen radicals accumulate and interfere with cell functions. Lots of different kinds of cells suffer when this happens: digestive cells, immune cells, and brain cells, just to name a few.
One form of suffering brought on by this excess of oxygen radicals has to do with the way cells repair damage from allergens or pollutants. In addition to the gene team that makes glutathione, each cell has teams of repair genes. A handicapped gene in a repair team may become even more handicapped when it is stressed by the poisonous accumulation of oxygen radicals. So repair slows down. When your cells have unrepaired damage, they send out calls for help, and the first thing your body does is mount a defense that includes inflammation. If the damage remains unrepaired, the inflammation may become chronic: you get chronic digestive problems, chronic allergic problems, and chronic inflammation of the brain.
So here and there a handicapped glutathione gene plus a handicapped repair gene might lead to what we call autism. And the rising number of kids with autism might be an indication of what can happen to human beings in a polluted environment.

Great article, Julie.
A friend just told me about a wonderful organization called Autism Speaks. It is filled with resources.

Thanks, Melissa, I checked out this website and found it very diverse and up-to-date! Julie
According to my investigation, billions of people on our planet get the personal loans at various banks. So, there's good chances to find a secured loan in all countries.
