Food and nut Allergies.

Extracts from this document...


Food Allergies. Many people believe they have a food allergy or intolerance and exclude particular foods from their diet. If this applies to just one or two specific foods, or if you can substitute another similar food in its place, such as rice instead of potatoes, or pears instead of apples, your diet is unlikely to suffer. However you should not exclude whole food groups, staple food items such as bread or meat from your diet, or long lists of different foods, without speaking to a doctor or dietitian. One of the dangers of self-diagnosing food intolerances, especially in children, is that it can lead to very restricted diets, which may lack important nutrients. Children with suspected food intolerances should always see a dietitian to ensure that they are consuming enough to meet all their nutritional needs. Children are often fussy eaters at the best of times so never add to the difficulties by excluding a food without good reason. ...read more.


The IgE antibodies attach themselves to special cells called mast cells, which can be found in the skin, lungs, upper respiratory tract and in the lining of the stomach. Contact with the allergen leads to an excessive reaction from the immune system whereby the mast cells suddenly release powerful chemicals including histamine. The chemicals are released in order to destroy the foreign protein or allergen. The release of the chemical histamine has a number of effects on the body, which we term the allergic reaction. Allergic reactions tend to occur in the parts of the body at which the immune system is activated. Food allergy - where the protein is ingested, can cause both local problems (swelling or itching of the lips tongue and throat) as well as sometimes causing nausea, vomiting, diarrhoea and stomach pains when swallowed. The body absorbs food from the bowel, which then enters into the bloodstream and can then permeate all parts of the body, so that some people also suffer a range of reactions such as skin rashes, joint pain, headaches, palpitations and rhinitus. ...read more.


* Loses things needed for activities at school and at home * Appears not to listen * Doesn't pay close attention to details * Seems disorganized * Has trouble with tasks that require planning ahead * Forgets things * Is easily distracted People used to think that ADHD was the result of some type of brain damage. We now know that the brain structure of children with ADHD is normal, but the chemistry in the brain isn't normal. Children with ADHD do not make enough chemicals in key areas in the brain that are responsible for organizing thought. Without enough of these chemicals, the organizing centers of the brain don't work well. This causes the symptoms in children with ADHD. Bad parenting doesn't cause ADHD, but a disorganized home life and school environment can make the symptoms worse. ADHD isn't caused by a diet that contains too much sugar, too little sugar or aspartame (brand name: Nutrasweet). Food additives, food colourings, food allergies or other allergies, or a lack of vitamins doesn't cause it. Too much TV, fluorescent lights or video games also don't cause it. ...read more.
