Top 10 Most Common Food Allergies

1 2

Food allergies should not be confused with intolerance for certain food items. Lactose intolerance is caused by a scarcity of the enzyme lactase and can lead to bloating and digestive problems. Whereas,  a milk allergy can cause severe immediate or delayed reactions, whenever a food item containing milk in any form is consumed. Allergies which occur in childhood often go away after a certain length of time, but adult allergies normally remain through a lifetime.

The most common food Allergies are as follows:

 

1. Fish

Fish allergies are among the most widespread allergies in the world. Shellfish is frequently the main culprit but there are many who are allergic to all types of fish. It does not seem to affect children as much as it does adults, and in some cases people are allergic only to cooked fish and not raw fish. The reactions are severe and anaphylaxis can be one of the resultant problems.

 

2. Shellfish

Shellfish allergy is probably the most common allergy among adults. It generally appears later in life and in some cases the reactions can occur even from airborne particles when shellfish is being boiled or cooked. Cat food which often has shellfish ingredients in it can also cause an allergic reaction.

 

3. Peanuts

 

Allergy to peanuts is also one of the world’s most prevalent ones. This allergy is different from nut allergy since peanuts are generally considered to be legumes rather than nuts. A lifelong allergy, in some cases it is so acute that even eating food from a utensil in which peanuts have been cooked earlier can cause an intense reaction.

4. Tree Nuts

 

Other nuts such as walnuts, pine nuts, cashews, macademia nuts, almonds and pecans can be a cause of an allergic reaction in some people. There are some who are allergic to only one kind of nut, but as a safety precaution they stay away from all varieties of nuts.

 

5. Eggs

 

This is one of the few allergies which seems to go away once a child grows older. The proteins in the eggs known as ovumucoid, ovalbumin and conalbumin are responsible for creating these allergies. Cooking does not kill all of them, hence eggs are not consumed in any form by these children or the rare adults who suffer from egg allergies.

    As someone who is allergic to all berries except strawberries, I would like to point out that the strawberry is not a berry. It’s actually, genetically, part of the rose family. It should not be considered a berry allergen; unlike raspberries, blueberries, cranberries, and the like.
