We recently listened to a podcast by Professor Gideon Lack, a leading UK based paediatrician specializing in children's allergies. With so many young children being affected by some kind of allergy these days, we thought we'd summarize this extremely informative podcast for you!

In case you are interested in hearing the whole talk (we think all parents should), here are some links to the episode on popular podcasting platforms:

In this episode of ZOE Science & Nutrition, they discuss the rise in allergies, the ineffectiveness of traditional prevention methods, and the importance of early exposure to allergens.

Please note the below summary should not be considered medical advice and you should seek independent advice that is relevant to your child's situation.

Key Takeaways 💡

• Professor Gideon Lack's research over five years led to significant changes in public health guidelines in the US and UK regarding allergy prevention.
• Traditional methods to prevent allergies, such as avoiding allergenic foods, were found to be ineffective and contributed to the increase in allergies.
• Gideon confirms that we are in an allergy epidemic and that allergies can develop at any point in life. He also states that measures can be taken to prevent allergies, but most people are not taking the right steps.
• Avoiding certain foods to protect children from developing allergies creates an 'immunological cocoon,' which is ineffective.
• Food allergies involve an immune system attack on foreign proteins, such as peanuts or eggs, leading to symptoms like facial flushing, hives, swelling, vomiting, wheezing, and potentially life-threatening cardiac effects.
• The prevalence of peanut allergies has risen significantly, with 2% of school children in the UK affected. The increase in food allergies has been 10-20 times over the last 40 to 100 years.
• Early exposure to foods is crucial for developing long-term tolerance, as demonstrated by a study comparing 5,000 Jewish children in the UK with 5,000 Israeli children, revealing a tenfold higher rate of peanut allergies in the UK.
• A randomized control trial (RCT) involving 640 high-risk babies showed that early peanut consumption reduced allergy rates by 85%, comparable to vaccine efficacy.
• Current guidelines recommend that babies aged four to six months should consume peanuts to prevent allergies, with a necessary quantity of about two heaping tablespoons of peanut butter weekly.
• The microbiome, including gut and skin microbiomes, plays a critical role in allergy development. Modern hygiene practices may disrupt the skin barrier and microbial balance, contributing to increased allergy rates.
• Pregnant women should maintain a normal, healthy diet without avoiding specific foods. Exclusive breastfeeding for the first three months is recommended, followed by early introduction of common allergens like peanut, egg, and milk.
• Banning nuts in schools is not practical, and families need to learn to manage allergies rather than isolate children from potential allergens. Treatments like desensitization and monoclonal antibodies are becoming more available.
• Early exposure to allergens like peanuts, eggs, and milk is crucial for preventing allergies, countering previous advice to avoid them.
• The episode wraps up with a focus on the microbiome's role in combating allergies and an invitation to access additional health and nutrition resources.

Some of the above points may come as a surprise as they are certainly not mainstream ways of dealing with this widespread problem. We hope they prompt further thought on the topic, and if you decide to incorporate his ideas, then please do so with the consent of your doctor.
