Foods often play an important role in causing, at least, two types of skin problems- hives and eczemas. Although, there are several types of eczemas which are not caused due to food allergies, 'atopic eczema' is frequently its resultant. Certain food scuffs, such as milk, eggs and preserved foods are most likely to cause allergies. A person may also be allergic to more than one food stuff. Often a number of hours elapse before the reaction occurs; so it is quite a problem to identify the culprit. Luckily, most people outgrow their food allergies and it is really not always necessary to look very carefully for the causative agent.
