hydrolysed protein or amino acid elemental formula.
Wheat and gluten
Wheat is the grain that is most often associated with allergies, but even at that, wheat allergy is relatively uncommon. There are two types of negative immune reactions to wheat.
“People who are allergic to eggs, are primarily reacting to the protein in the egg white, but such patients are generally advised to avoid eggs altogether”
One is classic food allergy, which manifests itself in the typical symptoms of hives or wheezing. The second is coeliac disease, of which the main symptoms are abdominal pain, diarrhoea, irritability, poor weight gain and slow growth.
> Eggs
People who are allergic to eggs, are primarily reacting to the protein in the egg white, but such patients are generally advised to avoid eggs altogether. Some vaccines also contain egg proteins and, as such, should be avoided by those with severe egg allergy.
Peanuts/tree nuts Did you know that a peanut isn’t actually a nut? It’s actually a legume: a ‘cousin’ to peas and beans. The fact that peanuts and tree nuts come from different families means that someone who is sensitive or allergic to peanuts can often eat walnuts, pecans and other tree nuts without problems.
One of the main problems with a peanut allergy is that they are often ground up and used as bulking
agents in food products such as sweets. It’s for that reason that those affected by peanut allergy need to read labels carefully to ensure that peanuts are not unsuspected ingredients in commercial foods.
allergy to tree nuts can be just as severe as peanut allergy. Sufferers can be allergic to one type of tree nut and not to others, but since confusion can often occur about the different types of tree nuts, those affected by tree nut allergy should be advised to stay away from all of them.
Soya
While often recommended as an alternative to cows' milk, soya can often cause similar allergy symptoms such as a rash, runny nose, wheezing or vomiting. In such cases, gPs may recommend a low-allergenic formula which is made with extensively
coeliac disease is caused by a protein called gluten, which damages the lining of the small intestine and interferes with nutrient absorption. The damage can begin in childhood and the symptoms are so minor that the condition can smoulder for years, with diagnosis not made until adolescence or even adulthood.
Treatment for food allergy unfortunately, there is no medication to prevent food allergy. The goal of any ‘treatment’ for allergy is avoiding the foods that cause the symptoms, as discussed above.
Where treatment IS most definitely required, however, is in the case of anaphylaxis.
Anaphylaxis
anaphylaxis is a very severe allergic reaction to foods that can result in a life-threatening collapse of the respiratory and circulatory system. anaphylaxis – or anaphylactic shock - includes a wide range of symptoms that can start soon after exposure to an allergy trigger.
LATEST NEWS ON FOOD ALLERGY Nestlé acquires company that treats peanut allergies
In February of this year, the first treatment for peanut allergies in children was approved in the united States. The drug ar101, or Palforzia, comes in the form of a powder, which is sprinkled on food. children are given tiny but increasing amounts of peanut protein over a six-month period under medical supervision and then have to take a daily dose to be able to tolerate accidental exposure.
at the time, scientists at King’s college London said that the oral immunotherapy offered ‘protection but not a cure’ for peanut allergies, with treatment only effective while patients continued taking small amounts of the allergen.
now the manufacturer of Palforzia, aimmune Therapeutics Inc, has been acquired by nestlé health Science. The acquisition is an extension of nestlé’s food allergy portfolio, creating a broader spectrum of solutions for children living with food allergies.
‘This transaction brings together nestlé's nutritional science leadership with one of the most innovative companies in food allergy treatment,’ said nestlé health Science ceO, greg Behar. ‘Together we will be able to offer a wide range of solutions that can transform the lives of people suffering from food allergies around the world.’

Symptoms include: • Shortness of breath, coughing or tightness in chest
• Trouble breathing or swallowing • rash, redness or hives on the skin, and skin becoming pale or bluish
• Swelling of the lips or tongue • Weak pulse, symptoms of shock • Tight throat, difficulty swallowing, hoarseness
Treatment of anaphylaxis The main treatment for the life- threatening symptoms of anaphylaxis is epinephrine. This is a life-saving drug that treats the symptoms of anaphylactic shock by stopping the airway from swelling and is administered by an auto-injector syringe, usually into the muscles of the outer part of the thigh.
The procedure for any type of auto- injector is similar: the safety cap is removed and the end with the needles pushed firmly into the fleshy outer portion of the thigh. The auto- injector is then held in place for a few seconds until all of the medicine is injected. The needle is then removed by pulling the pen straight out and the area is massaged.
epinephrine auto-injectors are prescribed for anyone who has ever had an anaphylactic attack and for children, who are at high risk of anaphylaxis. epinephrine auto-injectors are available in school or childcare settings and staff are generally trained about how to use them.
unfortunately, people who have had a severe allergic reaction are at risk for future reactions. even if the first reaction is mild, future reactions can be more severe, so it’s important for those, who are at risk of anaphylaxis to carry self-injectable epinephrine.
