For some food allergy sufferers, it can be quite easy to diagnose exactly which foods trigger a reaction because it is instantaneous. However, what happens when it is not so clear cut and dried? Typically, it depends on the type of symptoms you get as to which tests your doctor will perform to come to a definitive cause. There are five primary ways that your doctor will use to derive an answer.

Family History

In your very first appointment with the doctor regarding your probable food allergies, they will likely conduct a physical inspection and assessment of your body and overall health. In addition, the doctor and nurse will ask a series of questions about the overall health and genetic history of the family.

Children are allergic to foods such as eggs, milk, peanuts, soy, and wheat. Sometimes they outgrow these food allergies and sometimes they are still allergic to certain foods as adults. Children are more likely to outgrow milk or soy allergies than they are to outgrow peanut, fish or shrimp allergies.

Adults are typically allergic to foods such as:

• Shellfish
• Shrimp
• Crayfish
• Lobster
• Crab
• Peanuts
• Tree nuts such as walnuts
• Fish
• Eggs.

If an adult is still having allergic reactions to food, they are not likely to "outgrow" the allergic reaction tendency.

Food allergies are a reaction by the immune system's eosinophils, which are proteins that are activated in a histamine reaction. They are reacting to any foreign proteins, in other words they recognize particular food as foreign bodies to combat against. Certain vaccines are still egg-based such as the Influenza vaccines and the Yellow Fever vaccine.

One theory is that these egg based vaccines and the fact that they work based on soliciting a response from the body is just a theory and not based in evidence. Another theory is that a young infant's immune system is not ready to handle food proteins and so starts to attack them.

Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People with celiac disease are unable to tolerate a protein called gluten, which is found in wheat, rye, and barley. Gluten is found mainly in foods, but may also be found in products which are used every day, including stamp and envelope adhesive, medicines, and vitamins.

Because the body’s own immune system causes the damage, celiac disease is considered an autoimmune disorder. It is also classified as a disease of malabsorption because the nutrients are not absorbed. Celiac disease is also known as celiac sprue, non-tropical sprue, and gluten sensitive enteropathy.

Autoimmune Syndromes

It is not easy living with milk allergy because there are so many foods that contain milk and milk products that avoiding them can be difficult. Having a guide can relive some of this anxiety.

If you love to bake or cook, you can easily substitute for milk in recipes. You can substitute equal amounts of water or fruit juice in must recipes that call for milk.

There are lots of food items that you would not necessarily think of as "milk or milk product" and also you must be careful of purchasing from a deli counter as sometimes cheese and meats are sliced on the same deli meat slicer machine and you may inadvertently get some milk product in with your meat.
