Food allergies in kids are increasing

Published on November 1, 2010 in Health and Wellness. 0 Comments Tags: , , , , , , .

Many elementary teachers are noticing that more and more children have food allergies. Well, it is a fact that food allergies among children are definitely increasing. In fact, between 1997 and 2007, the amount of children with food allergies has increased by an astounding 18 percent.

Some people believe it is because of the ever increasing awareness of food allergy signs and symptoms. There is also more food allergy testing available to the public.

There is some evidence that these increasing amounts of food allergies is an actuality and not perceived, as some have believed in the past. A study from the Children’s Hospital of Boston reported that pediatric emergency room visits because of food allergies has doubled between 2001 and 2006. Currently, it is believed that 4 percent of U.S. children have food allergies.

It is not known why food allergies are rising. There are many explanations.

Milk, eggs, nuts, soy, fish and wheat are the most common allergenic foods. Some people think that bringing these foods into a child’s diet too early might lead to a food allergy. On the flip side, some experts believe that delaying the introduction of these foods could be the reason. Family history can also come into play.

Parents will definitely continue to hear confusing advice about prevention of these food allergies, until scientists finally are able to discover the reason for these allergies to occur. At the moment, the American Academy of Pediatrics suggests breast-feeding only until six months of age. Following this advice has been proven in studies to bring down the occurrence of food allergies and eczema.

After an infant has turned six months old, the AAP doesn’t recommend holding off on introducing any particular type of food group. This said, be sure to check with your doctor about specific advice about the introduction of solid foods if your infant has eczema, asthma, known food allergies or a family history of food allergies.

Smoking bans have benefited kids with asthma

Recent research has indicated that smoking bans have spared many children with asthma from having to be hospitalized. This finding demonstrates that smoke-free laws have even better health benefits than earlier believed.

Previous studies have kept track of the decrease in adult heart attack rates after smoking bans were embraced. This new study, which was performed in Scotland, observed asthma-related hospitalizations of kids. These hospitalizations decreased 13 percent a year after smoking was barred in 2006 from workplaces and public buildings, including bars and restaurants.

Before the ban came into effect, admissions had been rising 5 percent a year in Scotland, which happens to have a very poor health record among European countries.

Earlier U.S. studies performed in Arizona and Kentucky, showed similar results, but this was the most substantial study of its kind and it provided the most convincing case that smoking bans can generate immediate health improvements for vast amounts of people.

A University of California-San Francisco researcher who specializes in the health effects of smoking said “the effects of smoke-free laws are way bigger than you would expect.”

Common cold cure may be within reach

Curing the common cold may soon become a reality for researchers. On February 12, some researchers claimed that they have decoded the genomes of the 99 strains of the common cold virus. They have also established a catalog of the cold virus’ weaknesses.

The common cold has resisted treatment in the past because of the rhinovirus. This virus causes most colds, and it has so many strains that it is extremely difficult for any drug or vaccine to conquer it.

Another obstruction to drug advancement is that colds in general are usually only a minor inconvenience, which causes people to be hesitant to pay for expensive medicines to combat them. In the past, it has been unlikely for the Food and Drug Administration to give the green light for a drug that has any negative consequences for such a minor disease, and pharmaceutical companies haven’t shown a lot of enthusiasm for investing in discovering new treatments.

New understanding of the rhinovirus’ evolutionary action from a research team conducted by Dr. Claire Fraser-Liggett, a top genome researcher at the University of Maryland, and Dr. Ann Palmenberg, a cold virologist from the University of Wisconsin, may have finally put an end to this inefficient pattern. The results were published online in the February 12 issue of journal Science.

Physicians who are experts on asthma are especially interested in these new findings. About half of all asthma attacks are believed to be set off by rhinoviruses. An asthma expert from the University of Arizona, claims that it should now be possible to indicate what specific part contains viruses that are most related to asthma patients.

Dr. Kathryn Miller, another asthma expert at the Vanderbilt Children’s Hospital in Nashville, said that the new discovery “is a groundbreaking study of major significance to the scientific world.” He said that people who are at substantial risk from rhinoviruses, like children with asthma or adults with chronic obstructive pulmonary disease, would profit immensely from new medicine, therefore the pharmaceutical industry should be intensely interested. But according to Dr. Glenn Tillotson, an expert in antiviral drugs at Viropharma in Exton, Pa., it may be more difficult to spark the industry’s interest for new common cold treatments than it is for the researchers and physicians.
