Can you believe this? Wow.

interesting that the biggest allergy group is age 20-29, people not even alive when the previous figure, 30 years ago was reported. One obvious thing is that this is probably the maximum vaccinated group-they've had more vaccines than the kids and, due to newly introduced vaccines over the last 30 years, more than the people over 30. Vaccines interfere with the natural development of the immune system.
Of course, there's also the changing diet over the years and all those anti-bacterial cleaners in the house and mom at work means the kids lock themselves in the house and play video games or do homework (or cook dinner) instead of going out and playing in the neighborhood. Rising crime rates contributes to that too.
New issue I've been thinking about, now that we know about stem cells.Robert S Mendelsohn MD in his books, How to raise a healthy child in spite of your doctor
confessions of a medical heretic
and Malepractice
talked of the need, when delivering a baby, to let all the blood go into the baby before tying off the cord-it's the baby's blood. He said to wait for the cord to stop pulsing and to turn whitish so the baby would get all its blood. This was a kind of common sense thing, as well as an explanation of the phenomena of 'blue baby' which only happens with 2nd and subsequent births- he said it was caused by a too soon tied cord letting the baby's blood back up into the mother and causing her to produce antibodies to that blood, which could affect subsequent babies.
So, with this new emphasis on banking cord blood (not letting the baby have it) and the old medical 'management' of birth, which involves tying off the cord soonest so the baby can be separated from it's mom and the med people start intervening earliest in the baby's life, the question would be- are we making weaker babies with less strong immune systems be denying them their full measure of stem cells right at birth?
I may post this issue sometime, meanwhile- what do you think?

Good thoughts, Ann. Add to all this more environmental toxins of all sorts, which stress the whole body including the immune system. I never heard of this cord blood situation before. I hope you post more on it.

Hi Michele,

Another unmentioned possibility for increased allergies and asthma could have to do with energy conservation..
Tighter houses with less fresh air allowed to leak in, can cause stale air. Higher humidity can cause Fungus and molds can build up in cold drafty areas during the winter.
Most new furniture floor coverings and appliances have volatile chemicals which are released into the air.

Lack of exposure to allergens and bacteria as a child can also rob us of the antibodies that should protect us in
later life.
All of this can make breathing more of a chore if not a
risk.

Thanks, Sapphire.

At LEAST doubled and increasing faster every year. Just as I have been saying on this 'site for years.

More than half of all Americans test positive in response to one or more allergens, double the percentage who did 30 years ago, a new study reports.

Researchers at the
National Institutes of Health found that 54% of people tested positive to at least one of 10 allergens. The highest response was to dust mites, 27.5%. The lowest was to peanuts, 8.6%. The findings appear in the August issue of the Journal of Allergy and Clinical Immunology.

Researchers analyzed data from skin-prick allergy tests on 10,500 people by the Centers for Disease Control and Prevention.

The number of positive reactions is much higher than cases of actual allergic disease, notes lead researcher Samuel Arbes of the National Institutes of Health. Though a positive skin test for allergens such as ragweed or cats doesn't necessarily mean a person has or will develop allergies, there is a strong association between the two.

About 20% of U.S. residents have allergies or hay fever; 8% to 10% have asthma.

The doubling of the prevalence of the six allergens tested in the earlier survey corresponds to a period during which there also was a 74% increase in asthma, Arbes says. Though there is evidence asthma rates have peaked, allergy rates appear to still be increasing, he says.

The testing was part of
CDC's third National Health and Nutrition Examination Survey from 1988 to 1994 and is considered the most complete national data available to scientists. The previous survey was from 1976 to 1980.

Those at highest risk of showing allergic response were people ages 20 to 29, males, minorities, people living in the West, people living in old homes and people who were not exposed to cigarette smoke.

Skin tests involve applying an allergen extract to skin, which is then lightly scratched. If the area swells, the patient has antibodies to the allergen.

Researchers don't know why positive skin tests, allergy and asthma are increasing. One theory is that people simply don't go outside as often - Americans spend an estimated 90% of their time indoors - and have higher exposures to indoor allergens.

Another theory is that children become more vulnerable when they are exposed to fewer bacteria and viruses. Some researchers believe that has an effect on the developing immune system.
