Vitamin Use in Infants May Cause Asthma

Children who take multivitamins may be at a greater risk of developing asthma and food allergies. Researchers believe vitamins may cause cell changes that increase the odds of an allergic reaction, but say as yet there is no proof this is the case. It was based on data from a U.S. government study that began following mothers and infants in 1991 and involved more than 8,000 children.

The study found an association between early infant multivitamin intake and asthma among black infants and an association between early infant multivitamin intake and food allergies in formula-fed infants. Previously it was found that if the environment is too clean that could lead to an increased rate of asthma. That is called the hygiene hypothesis.

Two years ago I wrote a letter to the medical journal Thorax that provides details on my approach for asthma it focuses on fat optimization as did my letter to the British Medical Journal that reviews my strategy on how to manage atopic dermatitis, which has many similarities to asthma.
