Causes, incidence, and risk factors
Allergies are pretty common. Both genes and environmental factors play a role.
The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens, which are generally harmless and in most people do not cause a problem.
But in a person with allergies, the immune response is oversensitive. When it recognizes an allergen, it releases chemicals such as histamines. which fight off the allergen. This causes allergy symptoms.
Common allergens include:
Drugs
Dust
Food
Insect bites
Mold
Pet dander
Pollen
Some people have allergy-like reactions to hot or cold temperatures, sunlight, or other environmental triggers. Sometimes, friction (rubbing or roughly stroking the skin) will cause symptoms.
A specific allergy is not usually passed down through families (inherited). However, if both your parents have allergies, you are likely to have allergies. The chance is greater if your mother has allergies.
Allergies may make certain medical conditions such as sinus problems, eczema, and asthma worse.
Late-Onset Allergies
Another reason why patients can develop allergies later in life is that they were not exposed to the item producing the allergy symptoms, and then they become exposed later in life. A great example of this is when people move, especially from one country to another and are exposed to new types of plants, trees, grasses or even indoor allergens like dust mites. It usually takes a few years after moving to the new location that these patients will develop the allergic antibody (IgE) to these new items and then develop the common allergic symptoms.
Allergies are a significant health risk reaching epidemic proportions. One in four people suffer from allergies and as many as one in two in urban areas. It is estimated that greater than 60 million Americans are affected. The financial toll on patients, employers, and the healthcare system is greater than $18 billion per year. It is among the country's most common, yet overlooked diseases. Despite the clinical and financial impact, few seek proper diagnosis and disease management.
Allergies are more than just a seasonal inconvenience. Fifty six percent of allergy sufferers experience symptoms throughout the year. Of those with perennial allergies, 71% experience worsening symptoms during certain times of year. Without proper diagnosis and treatment allergies lead to asthma and other co-morbidities. In fact allergies represent the sixth leading cause of chronic illness in the USA. They are becoming an increasingly serious concern for children. Employers should look not just at the impact of allergies on their employees but also on the impacts on their family members.
Costs due to allergic rhinitis can be divided into two categories: direct costs that are related to monies spent on the course of managing the disease and indirect costs that are due to missing work and decreased productivity due to the illness. There are also the costs associated with the co morbidities of allergic rhinitis, such as sinusitis and asthma, which are classified as “hidden” direct costs.

I remember reading a theory that allergies were caused by dairy consumption.

Not sure about what else is out there but I can tell you that I have seen a rise in Celiacs (Gluten Allergy) in my bakery. So much so that we are considering full on gluten free baking and dropping everything else. We have a GF section that is growing faster than we can produce so something is up.
One other thing is that I had never heard of GF in Asia until I returned to N. America.

Wonder if there is a link to the GMOs flooding our food chain, and the body reacting to it.
I'll bet there is a link.
