Neonatal Gut Bacteria Might Promote Asthma

The worse the intestinal flora of babies the higher their chance of asthma later on. High carbohydrate foods (candy, breads, cereal, etc.) and antibiotics increase the amount of bad bacteria in the gut leading to these problems. 

"Abnormal gut microbiota communities present in some 1-month-old children promote inflammation that results in an almost threefold increased risk of developing allergies by age 2, according to a study published in Nature Medicine. More of these kids—who had lower levels of four commensal gut bacteria groups and 
higher relative levels of two types of fungi—developed signs of asthma by age 4."
