Pearls And Other Issues
Food allergic reactions are the most common cause of anaphylaxis seen in hospital emergency departments in the United States. Anaphylaxis is a potentially fatal allergic reaction that occurs rapidly and involves multiple systems including cutaneous, cardiovascular, respiratory, and gastrointestinal symptom.
Christian Churches And The Eucharist
Speaking generally, the various denominations of Christians celebrate a in which a wafer or small piece of from wheat bread is blessed and then eaten. A typical wafer weighs about half a gram. contains around 10 to 13% gluten, so a single communion wafer may have more than 50 mg of gluten, an amount that harms many people with coeliac, especially if consumed every day .
Many Christian churches offer their communicants gluten-free alternatives, usually in the form of a rice-based cracker or gluten-free bread. These include the , , , the Anglican Church and . may receive from the Chalice alone, or ask for gluten-reduced hosts gluten-free ones however are not considered to still be wheat bread and hence invalid matter.
Roman Catholic position
Roman Catholic states that for a valid , the bread to be used at must be made from wheat. Low-gluten meet all of the Catholic Church’s requirements, but they are not entirely gluten free. Requests to use rice wafers have been denied.
The issue is more complex for priests. As a celebrant, a priest is, for the fullness of the sacrifice of the Mass, absolutely required to receive under both species. On 24 July 2003, the Congregation for the Doctrine of the Faith stated, “Given the centrality of the celebration of the Eucharist in the life of a priest, one must proceed with great caution before admitting to Holy Orders those candidates unable to ingest gluten or alcohol without serious harm.”

What Causes Food Allergies
Food allergies happen when the immune system the body’s defence against infection mistakenly treats proteins found in food as a threat.
As a result, a number of chemicals are released. It’s these chemicals that cause the symptoms of an allergic reaction.
Almost any food can cause an allergic reaction, but there are certain foods that are responsible for most food allergies.
Foods that most commonly cause an allergic reaction are:
- some fruit and vegetables
Most children that have a food allergy will have experienced eczema during infancy. The worse the child’s eczema and the earlier it started, the more likely they are to have a food allergy.
Moral Ethical And Health
Many individuals limit what foods they eat for reasons of morality or other habits. For instance, choose to forgo food from animal sources to varying degrees. Others choose a , avoiding sugars or animal fats and increasing consumption of dietary fiber and ., a serious problem in the western world, leads to higher chances of developing , , cancer and many other diseases.

What Is The Medical Treatment For Allergic Reactions To Food
After getting advice from the health care professional, some mild allergic reactions may be treated at home. Any worsening of symptoms requires medical attention.
- In a severe reaction, the first priority is to protect the airway and blood pressure.
- The health care professional will make sure that the airway is open and that the person is getting enough oxygen.
- Oxygen may be given through a tube into the nose or by face mask.
- In severe respiratory distress, mechanical ventilation may be required. A tube is placed in the mouth to keep the airway open.
- In rare cases, a simple surgery is performed to open an airway.
- Blood pressure will be checked frequently.
- An IV line may be started.
- This is used to give saline solution to help boost blood pressure.
- It also may be used to give medication.
The person may need to be admitted to the hospital for further monitoring and treatment.
Are Food Allergies The Same As Food Intolerances
Food allergies are not the same as food intolerances. Allergies cause a response in your immune system. Allergies can be life-threatening.
Food intolerances cause a response in your digestive system. You may be able to eat a small amount of a food you are intolerant to without experiencing symptoms. Intolerances can be uncomfortable but arent usually dangerous.

Q : What Is Food Allergy
A food allergy is when the immune system reacts to a food , which is usually harmless. The immune system produces allergy antibodies called Immunoglobulin E that can result in symptoms.
A positive food allergy test means that a person’s immune system has produced an antibody response to that food. This is known as sensitisation. It is possible to have sensitisation without allergy, which means that the person can eat the food without any symptoms. For this reason, food allergy should be confirmed by a clinical immunology/allergy specialist.
Food allergy occurs in around 10% of infants, 4-8% of children, and about 2% of adults in Australia and New Zealand. The most common food allergens are cow’s milk , egg, peanut, tree nuts, sesame, soy, fish, shellfish and wheat. Almost any substance that is eaten can trigger an allergic reaction.
Mild or moderate food allergic reactions are common in Australia and New Zealand. Severe allergic reactions due to food allergy are less common and deaths from anaphylaxis are rare. Most deaths from anaphylaxis can be prevented by:
- Careful food allergen avoidance
- Correct posture during a reaction and
- Prompt administration of adrenaline .
Q : Is There Any Research Into Food Allergy
Research into why food allergy has become more common and prevention strategies is ongoing. It is not understood why food allergy has increased in recent years and possible explanations include:
- Hygiene hypothesis, which proposes that less exposure to infections in early life is associated with an increased chance of developing allergies.
- Delayed introduction of allergenic foods such as egg, peanut or tree nuts.
- Methods of food processing, such as roasted versus boiled peanuts.
- Development of allergy to food by skin exposure, such as the use of food-based skin products.
Research into food allergy treatment, management and epidemiology is also ongoing, including the areas of:
- Oral immunotherapy for food allergy, also known as desensitisation, to switch off food allergy once it has developed.
- Family history of food allergy, including why most children with food allergy do not have parents with food allergy, why their brothers and sisters have a slightly higher chance of having food allergy, and how this is affected by nationality and where the children and parents were born.

Severe Food Allergy In Children
Allergic reactions, including anaphylaxis, are common, although deaths from anaphylaxis are rare. Most schools and childcare services across Australia are required to have an anaphylaxis management policy in place.Banning particular foods is not recommended as it can create a sense of complacency and is difficult to monitor and enforce. A better approach is to educate staff, students and the community about the risks associated with anaphylaxis and put strategies in place to minimise exposure to known allergens.
Is Coconut Oil A Source Of Allergies
Coconut oil allergies are uncommon, and the coconut protein is a one-of-a-kind protein. This distinguishes it from cross allergies, which develop when someone with an established allergy reacts to foods containing comparable proteins. Coconut is safe to consume for most individuals with tree nut allergies.
When we think of food allergies, we often think of peanuts and shellfish, but there are numerous other food allergies that can be very serious. While most food allergies affect only a small number of people, others can be life-threatening. Food allergies can be caused by the consumption of a single food, such as peanuts, but they can also be caused by a reaction to multiple foods..

What Is The Outlook For People With Food Allergies
You can live a healthy life with a food allergy. If you have a food allergy, you need to carefully avoid all foods and ingredients that cause allergic reactions.
You may also need to take a nutritional supplement to replace any nutrients lost by avoiding your trigger foods. Speak with your healthcare provider or dietitian before starting a new eating plan.
What Are The Symptoms Of Anaphylaxis
Symptoms of anaphylaxis generally include two or more of these body systems.
- Skin: hives, swelling , itching, warmth, redness
- Respiratory : coughing, wheezing, shortness of breath, chest pain/tightness, throat tightness, hoarse voice, nasal congestion or hay fever-like symptoms , trouble swallowing
- Gastrointestinal : nausea, pain/cramps, vomiting, diarrhea
- Cardiovascular : paler than normal skin colour/blue colour, weak pulse, passing out, dizziness or lightheadedness, shock
- Other: anxiety, sense of doom , headache, uterine cramps, metallic taste
However, a drop in blood pressure without other symptoms may also indicate anaphylaxis. It is important to know that anaphylaxis can occur without hives.

What Are Food Allergens
Proteins in foods or derivatives of them that cause abnormal immune responses. Prevalence of food allergies around the world is believed to be increasing, with more than 8% of children and 2% of adults in countries like Australia and New Zealand having allergy to one or more foods. The most common allergens for young children are milk and egg but, fortunately, many children outgrow these allergies by the time they have reached 5-7 years of age. On the other hand, allergies such as those to seafood, peanut and tree nut may develop later and are lifelong conditions.
Practically all foods have the capacity to cause an allergic reaction in a person who has become sensitised to proteins in it. However, in Australia and New Zealand the foods or food groups that cause about 90% of all allergic reaction are identified as: peanuts specific named tree nuts: almond, Brazil nut, cashew, hazelnut, macadamia, pecan, pine nut, pistachio, and walnut soy milk egg wheat fish crustaceans molluscs sesame and lupin.
In addition to allergens, the ANZ Food Standards Code also requires gluten and added sulphites be declared due to their potential to cause non-allergic, hypersensitivity reactions.
There is currently no cure for food allergies but effective care and emergency treatments are available. The only successful method to manage a food allergy is avoidance of all foods containing the allergen.

What Are The Symptoms Of Food Allergies
Allergic symptoms may begin within minutes to an hour after eating the food. The following are the most common symptoms of a food allergy. But symptoms may occur a bit differently for each person. Symptoms may include:
Swelling and itching of lips and mouth
Tightness in the throat or hoarse voice
Nausea and vomiting
Low blood pressure
Loss of consciousness
Anaphylaxis is a medical emergency. to get help right away. Severe allergic reactions are treated with epinephrine. If you know you have severe allergies, you should carry an emergency kit with self-injecting epinephrine or Epi-pens.
How Can I Prevent Food Allergies
There is no known way to prevent food allergies in adults. In babies, breastfeeding in the first six months of life may prevent milk allergy. Early introduction of highly allergenic foods such as peanut protein and eggs into the diet may also have a preventative effect. Please discuss with your healthcare provider.

Which Foods Most Often Cause Food Allergies
About 9 in 10 food allergies are caused by these foods:
Some facts about food allergies:
Eggs, milk, and peanuts are the most common causes of food allergies in children.
Peanuts, tree nuts, fish, and shellfish commonly cause the most severe reactions.
Nearly 1 in 20 children under the age of 5 years have food allergies.
From 1997 to 2007, food allergies increased by 18% among children under age 18 years.
Most children “outgrow” their allergies. But allergies to peanuts, tree nuts, and shellfish may be lifelong.
According to the National Institute of Allergy and Infectious Diseases, it doesn’t take much food to cause a severe allergic reaction1/44,000 of a peanut can cause a severe reaction in a highly allergic person.
Q : Are Allergic Reactions To Inhaled Foods Common
No. Allergic reactions to food in the form of fine dust are uncommon. Most food proteins do not easily disperse as aerosols. Food handlers may have reactions to inhaled foods, including soy beans in processing plants, seafood allergens in some factories, and wheat dust in bakeries.
Foods which are more likely to cause an allergic reaction in the home environment in highly sensitised people include steam from cooking, which can carry particles of the food, and dried egg powder.
Most reactions that seem to occur without the food being eaten, especially in young children, are due to behaviours common in this age group, such as messy eating and mouthing objects. Volatile esters, which are carbohydrates, not proteins, can convey the smell of a food but cannot trigger symptoms.
Can Food Allergy Be Prevented
In 2017, guidelines were released by the U.S. National Institute of Allergy and Infectious Diseases on prevention of peanut allergy. These guidelines recommended introducing peanut to high-risk infants around 4-6 months of age to help prevent the development of peanut allergy.
In 2019, the Canadian Paediatric Society released on the specific timing of early introduction of allergenic foods for high-risk infants. The new guidance is to actively offer non-choking forms of foods containing common allergens around 6 months of age, but not before 4 months, as this can be effective in preventing food allergy in some high-risk infants.
Symptoms Of Food Allergy And Intolerance
It can be difficult to tell the difference between the symptoms of food allergy and food intolerance. Usually, symptoms caused by food allergy develop very soon after consuming the food. While symptoms caused by food intolerance can be immediate, they may also take 12 to 24 hours to develop.Food intolerance reactions are usually related to the amount of the food consumed. They may not occur until a certain amount of the food is eaten, but this amount varies for each person.The symptoms of food allergy and intolerance can also be caused by other conditions, so it is important to see your doctor for a medical diagnosis.

How Are Food Allergies Treated
When you know what foods you are allergic to, the best approach is to strictly eliminate those foods from your diet and to have emergency medications including epinephrine autoinjectors available at all times in case of accidental ingestion and reaction. Its important to seek emergency medical care immediately after using an epinephrine autoinjector. Wearing a medical alert identification indicating your food allergies is also recommended.
Your healthcare provider may prescribe medicines that reduce your allergic reaction symptoms. These medicines include:
- Epinephrine , a lifesaving emergency medication that immediately begins reversing symptoms of anaphylaxis.
- Antihistamines, medications that reduce itching or congestion.
- Corticosteroids to reduce swelling if you have a severe allergic reaction.
Enhancing Healthcare Team Outcomes
Food allergies have become a problem in society. Even though the risk of anaphylaxis is rare, there is hysteria over certain foods in schools, hotels, and in many public places. Parents and travelers have become demanding about foods, often resulting in major league arguments. The key is to educate the patient and caregiver. Managing food allergies requires an interprofessional team dedicated to the care of children.
All patients with a documented food allergy should be educated by the nurse to carry a self-injectable device that contains epinephrine. This device needs to be stored properly. The school nurse should provide the student with education on how and when to use the device. Older patients may be educated on the benefits of carrying an antihistamine in syrup or chewable form. More important, the pharmacist should educate the caregiver on how to use the epinephrine containing devices and how to identify an allergic reaction. The key is to avoid the allergen. A dietary consult is recommended so that the patient and the caregiver can be taught to identify food allergens and eliminate them from the diet. Parents should be educated about reading labels on foods and how to identify allergens.
