The term ‘food allergy’ should be reserved for those reactions where foods precipitate symptoms immunologically; classic allergic reactions are mediated by IgE and occur rapidly after ingestion of a very small quantity of the food concerned.
Food, however, can also precipitate symptoms by non-immunological mechanisms. If taken in sufficient quantity, pharmacologically active substances in food (such as caffeine or vasoactive amines) can affect some patients, and there are those who lack the necessary enzymes to metabolize substances such as lactose in cows’ milk. Enzyme deficiencies may be also be acquired, for example after treatment with monoamine-oxidase inhibitors. Such non-immunological reactions are usually termed ‘food intolerance’; larger quantities of food are necessary to produce them, and they are usually of slow and insidious onset.
Some food intolerance is probably caused by abnormal fermentation in the colon and it can follow gastroenteritis or antibiotic usage which has resulted in an unstable gut flora although it has also been reported in patients with normal gut flora. Although products of fermentation serving as diagnostic markers may be discovered in these patients, at present no simple test for food intolerance exists. There is popular interest in the suggestion that food intolerances are related to overgrowth of Candida in the colonic flora but, as there is no scientific evidence supporting this suggestion, treatment with antifungal agents is not justified in patients who are not immunosuppressed.
No reliable data are available as to the incidence and prevalence of food intolerance or allergy as a cause of gastrointestinal problems, reflecting the lack of a specific diagnostic marker. Read the rest of this entry »
Do you suffer from allergies? If you do, you are not alone. When it comes to allergy relief, many individuals head right to their medicine cabinets. While this approach is successful for many, what should you do if your medicine cabinet is empty and you are unable to visit your local drug store?
What many people do not realize is that there are many home remedies for allergies. Although these home remedies do work for many, they are not guaranteed to produce results.

Many allergy sufferers have great things to say concerning the use of lime. Although you may need to experiment a little bit, it is recommended that you squeeze half a lime into a cup. Added should be warm water. You may also want to add a few drops of honey for flavor, although this extra step is not required. In addition to helping with allergies, there are a number of other health benefits to consuming citrus fruits, such as lime.
Consuming other fruits and vegetables, namely those with antioxidants, have a number of benefits when dealing with allergies. They can help to improve your immune system, making it easier for you to fight off allergies or even avoid them in the first place. Fruits that you will want to try include apples and bananas. Although fruits and vegetables are easy to consume at home, you may also want to visit your local health store or drug store to examine their selection of healthy fruit juices, (such as goji, mangosteen, and noni) which have many of the same benefits.
The above mentioned steps are just a few of the many that you can take to lessen or completely eliminate the symptoms and inconveniences of allergies. Read the rest of this entry »
