It seems that almost anyone you talk to nowadays has a food allergy or knows someone who does. For some, it's more of a sensitivity, while for others, it can be life-threatening.

Food allergies

People can be allergic to fruits and vegetables, grains, various nuts, milk, eggs, and/or soy. Places like schools and restaurants are especially dangerous places for those with life-threatening allergies particularly if the exposure can occur through airborne particles.

The Centers for Disease Control and Prevention states that "Food allergies are a growing food safety and public health concern that affect an estimated 4 percent 6 percent of children in the United States. There is no cure for food allergies and reactions can be life threatening." Avoiding offending foods is the only way to make sure you don't have an allergic reaction, however it isn't always easy to completely avoid exposure or to find pre-packaged foods that don't contain certain allergens.

Some people can manage their allergies with shots or daily medicines, but that's not the case for everyone ... but according to a new study, you may be able to to outgrow your allergy.

A new study

Some allergies can come and go, and others present during childhood can be outgrown. A new study looked into how effective a test called a "food challenge" is "to determine whether a person can tolerate a food they once reacted to," stated WKMS.

In one instance, a fifth grade girl, Jula Cieciuch, went to her allergist at National Jewish Health Center where they repeated the standard allergy blood tests, which showed she may have outgrown her egg allergy. "The blood test measures the levels of a certain type of antibody, immunoglobulin E (IgE). The higher the level, the more likely a person is to have an allergic reaction. Jula's blood revealed a drop in antibody count," stated WKMS.

To confirm the results (under close medical supervision) Jula had to take the food challenge test actually eating the foods she's been allergic to. At first, the patient consumes a crumb-sized piece, then a larger amount, until you've eaten the entire item, which for Jula was a whole egg. If you have no reaction after eating the whole food item, you pass the test.

Results

Researchers studied 6,300 cases performed on adults and children who were thought to have outgrown an allergy. Of those, 14 percent had mild to moderate reactions and only two percent had more serious reactions requiring epinephrine.

But the majority of patients had no allergic reaction at all. That means that foods these patients were once allergic to, are now tolerated.

If your child has a food allergy, or if you had one as a child, you may want to be retested to see if the allergy is still present. If the blood test doesn't show a reaction, talk to your doctor about doing the food challenge under medical supervision. Don't try this on your own as severe reactions may occur in some cases.

Do you or your children suffer from food allergies? Have any of those allergies been outgrown? Would you consider doing the food challenge with your doctor's help to see if you're still allergic to certain foods?
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
