3 : food allergies

This time, I’m going to write about food allergies.

First, I am going to explain about food allergies simply.

I explained the process of allergies last time.

Food allergies are classified type1 allergies.

Everybody who has atopic diathesis has a possibility of cause symptom of food allergies suddenly.

A food allergy may causes anaphylactic shock and it is a matter of life and death even if the allergen was ate very small amount. Buckwheat and peanut, fish and shellfish, are particularly well known about that.

From infants through childhood, as main allergens, milk and egg accounted for more than half. Become more adolescence, shellfish, wheat, fruits, seafood are the main allergens and milk allergies reduce. In this way, if someone who has an allergy becomes an adult, whose allergies may to get better by some chance.

In these, it is especially well known that chocolate allergies are.

Foods such as cocoa and chocolate include angioedema substance called tyramine, and due to this. In addition, people be allergic to it may appears symptom because the cocoa also contains nickel (metal). Symptoms of these are varied diarrhea, vomiting, nosebleeds, abdominal pain and cramps and so on. And a nickel allergy may also cause anaphylactic shock. Deaths of it have been reported in Japan. Allergy symptoms may appear suddenly even those who had not come out any symptoms until now to eat chocolates. It is called "Valentine's Day syndrome" that the people who come to see a doctor with a chocolate allergy symptoms immediately after the day of Valentine's Day on February 14.

In this way, the foods that may be objects of indication in jure are determined by taking into consideration by the number of onset and severity in general.
