Though anaphylaxis is rare (alcohol accounts for only a small percentage of the United States' 150 annual food-related anaphylaxis fatalities), allergic reactions to wine and beer are relatively common. The causes of these reactions range from sulfites to sturgeon swim bladders. A single bottle of beer, for example, can contain more than 10 allergens, including preservatives, histamines, animal products, pesticides, wheat, yeast and corn. Why are these allergens added and what symptoms do they cause?
People with alpha-gal, a red meat allergy induced by tick bite, may accumulate more plaque in their arteries than those without the allergy, making them more susceptible to heart disease.
For more than 2000 years, sulfites have been used to prevent food spoilage and discoloration. Perhaps for nearly as long, they've played a more sinister role - causing allergic-type reactions in some of the people who consume them. Ellen Wiest is one such individual. She often suffered from headaches, severe nasal congestion, abdominal cramps and diarrhea after eating. But she didn't connect her symptoms to sulfites, until one June evening in 1995.
North Carolina resident Elizabeth Powell stood at the pharmacy counter, ready to buy the EpiPens her son needed for his multiple food allergies. She’d done this many times since the boy had his first anaphylactic reaction to peanuts ten years ago. Each time she would buy two EpiPen 2-Paks, ensuring he had one set at home and another when he was out and about.
It’s not uncommon for celiac disease to develop in older patients and it’s important to make the diagnosis, says a group of researchers in Finland and the U.K. In a new study published in Alimentary Pharmacology and Therapeutics, these researchers report that celiac disease is now being diagnosed more frequently in seniors. About a quarter of all celiac diagnoses are now made at the age of 60 and over. A fifth are made at 65 and older. And about 4 percent of new celiacs are diagnosed at age 80 and above.
Why are milk-allergic kids at risk for growth problems? Dairy constitutes a large part of the American diet, contributing calories and nutrients. In addition, children with milk allergy are more likely to have eczema and asthma, which may contribute negatively to growth rates, Keet noted, adding that additional study is needed. In the meantime, pediatricians and allergists should advise their patients about eating a healthy, nutrient-dense diet and monitor their growth over time.
People who suffer from hay fever (allergic rhinitis caused by pollen) can experience OAS when their immune system mistakes proteins in certain fruits or vegetables for the proteins found in their problem pollen. For example, when someone like Combs with a birch pollen allergy bites into an apple, the same IgE (immunoglobulin E) antibody that recognizes the birch pollen protein also recognizes a similar protein in the apple, prompting an allergic immune response, explains allergist Philip C. Halverson, MD, FAAAAI, of Allergy & Asthma Specialists in Minneapolis.
A classmate smeared peanut butter on his locker in middle school. A fifth-grade teacher threatened to give him a zero if he didn’t participate in a science experiment featuring peanut butter. A school parent ambushed him with an ultimatum: either sign a liability waiver in case he experienced anaphylaxis during a high school graduation party or don’t participate.
A new study found that food allergies are on the rise in adults as well as children. The increase is seen across all ethnic groups. About half of all food-allergic adults reported they developed one or more food allergies after age 18. Shellfish is the most common food allergy in adults, affecting an estimated 3.6 percent of adults in the United States. This is a 44 percent increase in prevalence from the rate recorded in 2004. The study also found that nut allergy in adults (now about 1.8 percent) has risen 260 percent since a 2008 estimate.
When I was growing up, I never thought about food allergies. Food was shared freely, lunch items were swapped at school and potlucks were a regular event. In my neighborhood, kids ate dinner wherever they happened to be in the evening. We could walk into friends’ homes and help ourselves—without thinking—to whatever was in their refrigerator.
