The term food allergy is often confused with food intolerance. Importantly, food allergy is only one of many possible reasons for the existence of food intolerance.
Food intolerance can be defined as a condition in which adverse effects occur after eating a particular food or cooking ingredient. Genuine food intolerance is different from psychological food aversion, in which the person hates a meal and think the food in question will produce a particular reaction.
The genuine food allergy occurs when an immune reaction occurs in the body determined in response to the ingestion of a particular food. Allergies are manifested in groups, so that people who are allergic to certain foods may also be allergic to other environmental factors such as dust, animal dander or pollen.
A true allergic response involves abnormal or altered reaction to an antigen tissue. An antigen can be a protein, a substance bound to a protein, added to a food additive, or less commonly, a polysaccharide. The antigen is combined with an antibody and produce an immune response, just in cellular damage and the release of histamine. The immune system plays a role in our bodies to protect us from the invasion of harmful substances. An allergy occurs when the immune system does not work properly with no harmful substance, such as a particular food protein.
Food intolerances, other than by allergy can occur due to various factors, including:
- Non-allergic histamine release
The symptoms are very similar to an allergy and can be headache, swelling, hives, vomiting and diarrhea. A substance called histamine is released (also released in allergic reactions authentic) in response to food such as shellfish or strawberries.
- Metabolism Deficiencies
The lack or deficiency of the enzymes responsible for the digestion of food can cause many kinds of food intolerance. For example, lactase deficiency, the enzyme responsible for the digestion of milk, because the milk intolerance.
Coeliac disease is an intestinal intolerance to a protein found in wheat, called gluten allergy should not be considered. The symptoms of celiac disease are controlled by following a gluten free diet. It is not known exactly how and why the gluten damages the small, but today it is believed that it is more of an abnormal immune response and not a deficiency of the enzyme. Neither is considered a food allergy in the strict sense of the definition.
- Pharmacological Effects
Some food substances can act as drugs, especially if taken in large quantities. The best known of these substances is caffeine, found in tea, coffee, chocolate and cola. A high intake of caffeine can cause tremor, migraine and palpitations. Among other pharmacologically active substances found in food include histamine, tyramine, tryptamine and serotonin, which can be consumed in foods such as red wine, cheese, yeast extract, avocados and bananas. In sensitive people, these foods can cause hives, flushing and headaches.
- Food intolerance of unknown origin
Reactions can occur as a result of many foods and food products that have not yet understood. They may or may not be allergic reactions. Food additives, particularly tartrazine and sodium benzoate, can cause urticaria, rhinitis and asthma. Yeasts can produce a series of reactions in some people, particularly skin disorders.
- Common causes of food intolerance
The most common food intolerances, in order of frequency, are: milk, eggs, nuts, fish / shellfish, wheat / flour, chocolate, artificial coloring, pork / bacon / bacon, chicken, tomato, soft fruit, cheese and yeast .
Although not all are related to food intolerances meat and dairy products, the list above shows that vegetarians and vegans in particular, will suffer less because they have food intolerances eliminated from your diet some of causes intolerance.
allergy season has been identified as the worst in recent years by the enormous amount of pollen that is loose in there, as a result of one of the toughest winters.

Vitamin D is essential for muscle strength and prevent cancer, diabetes and autoimmune diseases. It is also estimated that protects against asthma and allergies. Doctors recommend taking 2,000 international units of vitamin D if your levels are low. Vitamin D is also found naturally in sunlight, in egg yolk, herring and cod liver oils.
During the mornings and evenings the amount of pollen and allergens that are found in the environment increases. Try to keep your home windows closed during those hours, and also avoids jogging or walking. If you walk in the street during these hours, take a shower as soon as you get home to remove particles and allergens that may have lodged in your clothes, skin or hair.

Even those allergic to shellfish may react to fish has not been shown cross-reactivity between these foods. If mites are known to have proteins similar to shellfish so that mite-allergic patients have an increased risk of allergic reactions to shellfish than those who are not.

WHAT ARE THE DUST MITES?
Dust mites are tiny microscopic animals (measure approximately 0.3 mm) related to spiders (arthropods) living in nearly all parts of the world, preferring temperate zones and high relative humidity.
Their most common habitat is the powder inside the houses. As depend on the humidity and somewhat phobic to light, his favorite places to live are mattresses, pillows, stuffed animals, carpets, etc.. These places are also one of their favorite foods, such as human skin scales and animal.
Their depositions, and various parts of your body contain the volatilized particles and make contact with the mucosa (lining) occur in nasal and bronchial inflammation that they result in allergic rhinitis or bronchial asthma.
Unlike pollens, seasonality is less marked and are found all year round, especially in humid areas like the coast where its concentration (with exceptions) is much higher than in inland locations where the climate is drier.
Despite this difference between the coast and the drier areas in Chile is also prevalent in cities where the houses indoor damp or they exist in conditions that favor its growth such as carpets, stuffed animals, books, plants, etc.
