Researchers found bacteria common to the mouth and gut, especially Rothia aeria, can degrade peanut allergen proteins Ara h 1 and Ara h 2 in lab tests, markedly reducing allergenicity in vitro and correlating higher Rothia aeria with non-allergic or tolerant individuals; this points to potential probiotic or adjunct oral immunotherapy approaches for peanut allergy, with further work in animals and humans.
Researchers identify mouth and gut bacteria, notably Rothia and Staphylococcus, that can break down peanut proteins Ara h 1 and Ara h 2. In children undergoing oral immunotherapy, higher levels of these microbes correlate with greater peanut tolerance and milder reactions; mouse studies show the same bacteria reduce anaphylactic responses. The findings hint at microbiome-based markers and therapies to manage peanut allergy, but human applications remain observational and require further testing.
Peanut allergies among children have decreased by over 40% since 2017, largely due to changes in early introduction guidelines following research showing that introducing peanuts early in infancy can significantly reduce allergy risk. Experts recommend cautious early exposure, especially for high-risk children, and emphasize the importance of monitoring for allergic reactions. While early introduction doesn't guarantee prevention, recent evidence suggests it is an effective strategy to lower peanut allergy prevalence.
Research led by Dr. Gideon Lack overturned the long-held belief that avoiding peanuts in infancy prevents allergies, showing that early exposure actually reduces the risk of developing peanut allergies, leading to updated guidelines and a decline in allergy rates among children.
Reversing previous advice not to expose infants to peanuts, new guidelines recommending early introduction have significantly reduced peanut allergy cases among children, preventing an estimated 40,000 allergies over the past decade.
A new study shows that changing guidelines to encourage early peanut exposure in infants has led to a 43% reduction in peanut allergy diagnoses among children under 3, highlighting the effectiveness of early allergen introduction in preventing food allergies.
A study published in Pediatrics shows a 43% decrease in childhood peanut allergies following the 2017 updated early introduction guidelines, which recommend introducing peanuts to infants around 4-6 months, supporting the effectiveness of these public health recommendations. The study analyzed medical records of about 40,000 children and found no change in egg allergy rates, with eczema rates increasing during the same period.
A study finds that since the 2015 guidelines recommending early peanut introduction to infants, about 60,000 children have avoided developing peanut allergies, with a significant decline in new cases among young children, highlighting the impact of changing medical advice on public health.
A new study shows that early introduction of peanuts to infants, following updated guidelines, has prevented approximately 60,000 children in the U.S. from developing peanut allergies, with a significant decline in cases among children aged 0-3 since 2015. Despite initial slow adoption, the practice is gaining traction and offers a promising strategy to reduce food allergy prevalence.
Mondelēz Global LLC has voluntarily recalled certain sizes of RITZ Peanut Butter Cracker Sandwiches due to a labeling error that could cause allergic reactions in peanut-sensitive individuals, with no reported injuries so far.
Chloe Dickson, who has a severe peanut allergy, shares her experiences of being tested and misunderstood, highlighting the importance of awareness and safe spaces for allergy sufferers, and advocating for peanut-free environments in public places.
A woman with a lifelong severe peanut allergy undergoes oral immunotherapy, which involves gradually increasing peanut doses to desensitize her immune system, leading to a life-changing ability to eat peanuts safely and live more freely, despite ongoing maintenance requirements.
Dominique Brown, a Disney influencer and co-founder of Black Girl Disney, died after a medical emergency at a BoxLunch event in Los Angeles, reportedly due to a severe peanut allergy. Despite assurances of no peanuts in the food, Brown felt unwell and was taken to the hospital, where she passed away. An investigation into her death is ongoing. BoxLunch expressed condolences and support for her family and friends. Brown was known for her passion for Disney and her efforts to increase representation of Black women in the Disney community.
A new study published in NEJM Evidence suggests that introducing smooth peanut butter to infants as early as 4 months old and continuing until around age 5 can reduce the risk of developing a peanut allergy by 71% in adolescence. This approach, based on the principle of oral tolerance induction, has shown lasting protection against peanut allergies, even when peanut consumption is not consistent after age 5. The findings support early peanut introduction under pediatric guidance, especially for children at low risk for allergies.
A study led by King's College London and sponsored by the NIH found that introducing peanut products to children from infancy to age 5 significantly reduces the risk of developing a peanut allergy later in life. The research, published in NEJM Evidence, showed that early and regular peanut consumption provided lasting tolerance, even if peanuts were later avoided. This approach could prevent many cases of peanut allergy among children in the U.S. Detailed guidelines for safely introducing peanuts to infants are available.
