As stated in this study, breastfeeding has the ability to help reduce the early symptoms of allergy. An allergy is a reaction of your immune system to something that does not bother most other people. Breastfeeding in the first 4 to 6 months of life can reduce the risk of atopic eczema and cow's milk protein allergy. Allergies are often a result of a complex interaction between genetic and environmental factors. These factors can include pollution and tobacco smoke. If allergies are detected sooner, there is a greater chance of them being treated or possibly eliminated. Allergies plague most people and any research done to help prevent them is definitely a positive thing.
