Allergies are increasing in today’s children, so parents worry over the introduction of any new foods.

Allergies are the result of an overactive immune response to external substances. Most allergies are caused by lifestyles: external and internal factors both contribute to the problem. For your family, your grandmother’s generation had a stronger immune system than yours today; your family living out in the country is also better than you are.

1. External Factors

Now, children spend much more time indoors than outdoors. As house sealing conditions get better, artificial fragrance from household chemicals are becoming stronger. Carpets also harbor many dust mites. This indoor air pollution is the cause for some allergies.

2. Internal Factors

First, food diversity is significantly reduced. Americans only eat about 10 different types of foods every day. If you only eat a small variety of foods, any new food won’t be recognized by your body. At a supermarket, you see many seemingly different cans of food. In truth, many of the basic ingredients are more or less the same. Second, scientists found children who receive antibiotics in the first year of life have more than double the rate of allergies and asthma in later childhood. There are good bacteria inside stomach which help us to digest foods. When good bacteria are killed by antibiotics, you may not able to digest some foods, and you body will produce allergic reactions to them.

There is no cure for allergies today. Allergy medicines are only for relief from symptoms and are good for up to 24 hours. As they are getting stronger, so are their side effects.
