How This Controversial Food Is Solving the Baby Allergy Crisis by 85%! | Professor Gideon Lack

Live Well Be Well with Sarah Ann Macklin | Health, Lifestyle, Nutrition

In this fascinating episode of Live Well, Be Well, I sit down with Professor Gideon Lack, one of the world’s foremost experts on allergies. We dive deep into the rising prevalence of allergies, exploring the two significant waves of the allergy epidemic—respiratory and food-related—and what they mean for us today.

Professor Lack sheds light on the hygiene hypothesis, explaining how modern cleanliness impacts our immune systems and the skin barrier, potentially leading to allergies. We also discuss his pioneering LEAP study, which found that introducing peanuts early in life dramatically reduces the risk of peanut allergies—a revelation that’s reshaped allergy prevention guidelines.

We cover why some people develop allergies later in life, practical tips for managing both respiratory and food allergies, and the role pets and a less sanitised environment might play in reducing allergic conditions. Whether you’re curious about allergy prevention for infants or navigating allergies on a plant-based diet, this episode is packed with actionable insights to help you live well.
