What are food allergies?

By Arthur Marks


Many people downplay the effects of food allergies as mild ailments, but this is sadly not the case. Albeit some of their manifestations might be tolerable, there exist others that are thorns in the flesh for their sufferers. Thus, it is of paramount import that the public at large to appreciate the various forms which these ailments manifest themselves.

Food allergies often manifest their outward and inward manifestations due to ingesting of some types of food that can possibly be deemed as detrimental to the welfare of the human body. For the most part these disorders trigger the body's immune system to produce antibodies, which happen to be its natural guards against anything detrimental matter found in it. These antibodies react by stimulating the body to produce chemicals such as histamine to counteract the effects of food allergens (the substance of food in the food ingested, or even touched). Such chemicals are often the culprits behind every untoward manifestations of ingesting foods that cause allergies.

Food allergies are notably widespread among the younger generation, and according to statistics gathered by the US's food and drug administration (FDA) approximately 6% of children below the age of 3 in that specific country are struggling with food allergies. This same situation is significantly lower with grown ups.

The good news, however, is that most of these kids generally outgrow these ailments. This is especially true with milk allergies where an estimated 80% of these unfortunate children lose these ailments, while about 2/3 of those with egg, and 80% of those suffering from wheat and soy allergies often outgrow them by the time they hit age 5.

However, it is sad to note peanut ailments are apparently very stubborn with a paltry of 20% 0f children outgrowing them. Conversely, there happen to be other food allergies that develop later on in life, and are seldom outgrown. These include fish or shellfish allergies that stubbornly affect the lives of their sufferers.

Some people experience very extreme symptoms, but some are less severe. There is a lot of variety from one individual to the next.

Should such persons continue to partake of the allergy-causing meals, the body moves a step further, and starts to produce detrimental chemicals such as histamine to cope with seemingly untoward intrusion. This in effect makes the body exhibit the symptoms that are often attributed to such ailments. These include skin rashes, running noses, body swellings, abdominal discomforts, and a host of many others.

On the other hand, most people confuse such kinds of allergies to the milder food intolerance, as they often manifest similar symptoms, which include indigestion, migraines, burping or even loose stools. This, however, is not the case as food intolerance doesn't have any effect on the immune system, and is consequently, seldom as perilous as food allergies, which can actually cause death.
