Study finds new link between food allergies and multiple sclerosis   Like many other medical conditions, the mechanism of multiple sclerosis remains an enigma--a puzzle composed of complex genetic and environmental factors. A key piece to this puzzle is the immune system, which is also responsible for regulating many other physiological (and pathological) phenomena--including allergies.

Half of all food allergy sufferers are not actually allergic   A new study has shown that the food allergies that people claim to have may not be true. The study reveals that as many as 20 percent of Americans over the age of 18 years believe that they are allergic to one or more food items. The study finds that the actual number of people who have a food allergy is close to 10 percent of the population. They also show that one in 20 Americans had a diagnosed case of a food allergy.         Alpha-gal Allergy (Meat Allergy)   Alpha-gal allergy was first described in a few patients in 2009. Within 5 years it had become evident that they were only the tip of the iceberg. Alpha-gal allergy has a prevalence of thousands in some parts of the US and Europe.

Types of Eye Allergy   Eye allergies can be frequent and troublesome. The eyelids, which are the mucous membrane covering the eyes (conjunctiva), are the most frequent site of inflammation due to allergy. However, allergies can also affect the front of the eye (cornea), either in conjunction with allergic rhinitis or alone. In fact, about 40 – 60% of individuals with allergies will experience some kind of eye-related symptom.       Gut microbiome may help prevent development of cow's milk allergy   New research suggests that the gut microbiome may help prevent the development of cow's milk allergy. Scientists at the University of Chicago found that gut microbes from healthy human infant donors transplanted into mice protected animals exposed to milk from experiencing allergic reactions, while gut microbes transplanted from infants allergic to milk did not.       Scientists demonstrate key role of salt in allergic immune reactions   Salt apparently affects allergic immune reactions. A team working with Prof. Christina Zielinski at the Technical University of Munich has demonstrated in cell cultures that salt leads to the formation of Th2 cells.
