The recent allergy epidemic is caused by a combination of factors, including genetics, environmental changes, dietary habits, and lifestyle. Here are some key factors contributing to the increase in allergies: 1. Genetics: People with a family history of allergies are more likely to develop allergies themselves if they don’t follow the suggestions in this podcast. 2. Environmental factors: Changes in the environment, such as pollution in the air, water and food supply, urbanization and a lack of informed choices can impact the prevalence and severity of allergies. 3. Hygiene hypothesis: This theory suggests that decreased exposure to germs and microbes in early childhood may lead to an overactive immune system, increasing the risk of developing allergies. 4. Dietary changes: Western diets high in processed foods contribute to inflammation and weaken the immune system, making individuals more susceptible to allergies. Additionally, changes in agricultural practices have increased the allergenic potential of foods. 5. Changes in microbiota: Disruptions in the gut bacteria increase the risk of developing allergies. 6. Lifestyle factor: Factors that weaken the immune system increase susceptibility to allergies.
