Test for Food Allergies
  Food Allergies, Test For
 Recommended for…
 


Improvements in laboratory techniques have made blood testing for food and airborne allergens more reliable than they previously were. The test should include both IgE and IgG antibodies in order to identify both immediate and delayed type allergens. While an elimination diet is less expensive, it is more cumbersome and may result in confusion or discouragement, particularly in children.

Directions


Before having your blood tested, be sure to include any food you are suspicious of in your diet. The lab test may not indicate a reaction if you are not currently consuming that food.

Test for Food Allergies can help with the following:
Allergy  Allergy to Foods (Hidden)
  Allergic Tension Fatigue Syndrome

Autoimmune

  Crohn's Disease
 Finding out which foods may be triggering the inflammatory reaction is an important part of treating this disease. Often wheat, corn, dairy, and eggs are involved as in ulcerative colitis.

Circulation

  Arrhythmias/Dysrhythmias

Digestion

  Constipation
 Constipation triggered by food allergies might be responsible for chronic constipation in some adults. Individual foods, such as milk and milk-containing products, may be at fault in some individuals.

Immunity

  Weakened Immune System

Infections

  Sinusitis

Mental

  Attention Deficit Hyperactivity Disorder (ADHD)
 Allergies to one or more foods are often found in children with ADHD. Frequent offenders are milk, cane sugar, chocolate, American cheese, and wheat. [Annals Allergy Vol. 72, 1994, pp. 462-8]

  Anxiety

Metabolic

  Edema (Water Retention)
 Food sensitivities should be ruled out in cases of edema of unknown cause. "I often recommend an empirical elimination diet in which common allergens (wheat, milk, eggs, corn, coffee, tea, alcohol, yeast, citrus and sugar) are removed for several weeks. Although edema is usually not their primary complaint, many patients report a pronounced diuresis and loss of edema fluid during the first several days of the diet. Foods that cause a return of a patient's presenting symptoms often cause fluid retention as well". [Gaby, AR. Idiopathic edema: Letter. Hospital Practice Feb. 15, 1986, p. 21]

Edema is a very reliable and accurate index in detecting a food reaction that may cause the body to suddenly retain as much as 4% of its body weight as edema fluid. This weight is gained within 6-8 hours of ingesting the guilty food and lost within 18-24 hours after the food has been removed from the diet. [Brenerman, JC. Basics of Food Allergy. Springfield, IL, Charles C. Thomas, 1978]

  Migraine/Tension Headaches
 Food allergy may be a factor in as many as 80% of migraine sufferers. In one study of 60 patients, the average number of foods causing symptoms was 10 per patient. All patients improved when offending foods were eliminated and 85% became headache free. All 15 patients who had high blood pressure at start of study saw blood pressure return to normal. The following were most often implicated as a cause of migraine: cow's milk (30%); eggs (27%); chocolate (25%); oranges and wheat (24%); cheese and tomatoes (15%). Common food triggers of migraines were milk products, sweets, corn, beef, coffee and teas amongst others. While food allergies are an important factor in migraines, they play less of a role in tension type headaches.

  Problems Caused By Being Overweight
 Masked food allergy can be a factor in the development and persistence of obesity. [Abstract. J Lab Clin Med 32: p.1547, 1947]

  Bruxism (Clenching/Grinding Teeth)
 Teeth grinding may be aggravated by certain foods in some individuals.

Musculo-Skeletal

  Rheumatoid Arthritis
 While virtually any food can result in aggravation of rheumatoid arthritis, the most common offending foods are dairy protein, wheat, corn, citrus fruits, eggs, beef, sugar, fats, salt, caffeine and nightshade (Solanum) family foods (tomato, potato, eggplants, peppers and tobacco).

In order to test whether foods trigger symptoms, a food elimination protocol was followed in a blind, placebo-controlled study that resulted in significant improvement in arthritic symptoms, including shorter duration of morning stiffness and fewer painful joints. [Lancet 1986:1, pp.236-8]

While many doctors believe that the percentage of rheumatoid arthritis patients benefiting from diet manipulation is small, there is an increasing number of scientific studies suggesting that food elimination may help a higher percentage of patients.

"Nutritional therapy, not drugs, is the cornerstone of alternative treatment. A treatment for arthritis that relieves symptoms in a large percentage of patients is based on the theory that most arthritic symptoms are allergic reactions." [Jane Heimlich (wife of Dr. Henry Heimlich, the "Heimlich Maneuver" physican), in her book, "What Your Doctor Won't Tell You"]

Organ Health

  Gallbladder Disease
 See relationship between Gallbladder Disease and Allergies.

Respiratory

  Asthma
 Many studies have indicated that food allergies play an important role in asthma. Negative reactions to food may be immediate or delayed. Immediate onset sensitivities in children are usually due to egg, fish, shellfish, nuts, or peanuts. Foods most commonly associated with delayed onset include milk, chocolate, wheat, citrus, and food colorings. Elimination diets have been successful in treating asthma, especially for infants.

Skin-Hair-Nails

  Eczema
 Food allergy detection and elimination should not be overlooked in searching for the causes of eczema. Many studies have documented the major role that food allergy plays. In cases of atopic dermatitis, eggs, milk, wheat, soy protein and peanuts are the most common offending foods. Inhalant allergens such as house dust mite, pets, pollen and cut grass may also cause an acute flare-up of eczema.

  Hives
 Numerous clinical studies demonstrate that diets that are free of foods or food additives that commonly trigger allergic reactions typically produce significant reductions in 50-75% of people with chronic hives.

  Rosacea
 The incidence of migraine headaches and flushing accompanying rosacea points to some form of food intolerance.

Tumors, Benign

  Tendency To Develop Polyps
 Hidden food allergies are an underlying cause of polyp formation.

  Cysts
 Generalized cysts may be due to allergies. Allergy testing may be useful only if there are other allergy symptoms also.

Uro-Genital

  Urinary Stress/Urge Incontinence
 Naturopathic physicians and holistic medical doctors report countless success stories of treating this uncomfortable condition with changes in the diet that eliminate sensitive and/or inflammatory foods.

GLOSSARY

Acute
An illness or symptom of sudden onset, which generally has a short duration.

Allergen (Allergens)
A substance that is capable of producing an allergic response in the body.

Allergy (Allergies)
Hypersensitivity caused by exposure to a particular antigen (allergen), resulting in an increased reactivity to that antigen on subsequent exposure, sometimes with harmful immunologic consequences.

Antibody (Antibodies)
A type of serum protein (globulin) synthesized by white blood cells of the lymphoid type in response to an antigenic (foreign substance) stimulus. Antibodies are complex substances formed to neutralize or destroy these antigens in the blood. Antibody activity normally fights infection but can be damaging in allergies and a group of diseases that are called autoimmune diseases.

Arthritis (Arthritic)
Inflammation of a joint, usually accompanied by pain, swelling, and stiffness, and resulting from infection, trauma, degenerative changes, metabolic disturbances, or other causes. It occurs in various forms, such as bacterial arthritis, osteoarthritis, or rheumatoid arthritis. Osteoarthritis, the most common form, is characterized by a gradual loss of cartilage and often an overgrowth of bone at the joints.

Asthma (Asthmatic)
A lung disorder marked by attacks of breathing difficulty, wheezing, coughing, and thick mucus coming from the lungs. The episodes may be triggered by breathing foreign substances (allergens) or pollutants, infection, vigorous exercise, or emotional stress. Extrinsic Asthma is triggered by pollen, chemicals or some other external agent; Intrinsic Asthma is triggered by boggy membranes, congested tissues, or other native causes… even adrenalin stress or exertion.

Atopic (Atopic Allergy)
Genetically predisposed toward developing immediate hypersensitivity reactions to common environmental allergens.

Chronic (Chronicity)
Usually referring to chronic illness: Illness extending over a long period of time.

Constipation (Constipated)
Difficult, incomplete, or infrequent evacuation of dry, hardened feces from the bowels.

Cysts (Cyst)
A closed pocket or pouch of tissue; a cyst may form within any tissue in the body and can be filled with air, fluid, pus, or other material. Cysts within the lung generally are air-filled, while cysts involving the lymph system or kidneys are fluid filled. Cysts under the skin are benign, extremely common, movable lumps. These may develop as a result of infection, clogging of sebaceous glands, developmental abnormalities or around foreign bodies.

Dermatitis
A general term used to refer to eruptions or rashes on the skin.

Diuresis
Excessive discharge of urine.

Eczema
Swelling of the outer skin of unknown cause. In the early stage it may be itchy, red, have small blisters, and be swollen, and weeping. Later it becomes crusted, scaly, and thickened.

Edema
Abnormal accumulation of fluids within tissues resulting in swelling.

Gallbladder (Gall Bladder)
A small, digestive organ positioned under the liver, which concentrates and stores bile. Problems with the gallbladder often lead to gallbladder attacks, which usually occur after a fatty meal and at night. The following are the most common symptoms: steady, severe pain in the middle-upper abdomen or below the ribs on the right; pain in the back between the shoulder blades; pain under the right shoulder; nausea; vomiting; fever; chills; jaundice; abdominal bloating; intolerance of fatty foods; belching or gas; indigestion.

Idiopathic
Arising spontaneously or from an obscure or unknown cause.

IgE (Immunoglobulin E)
Immunoglobulin E is a type of antibody produced by IgE plasma cells. These are specialized B-cell lymphocytes that make free-floating antibodies for what is termed humoral resistance. IgE is not made to be specific against only one antigen, like other gamma globulins, but instead can bind with a number of dangerous proteins. IgE travels to mast cells, sticks to their surfaces, and when antigens get stuck to the IgE, the mast cells secrete inflammatory compounds such as histamine. Since IgE is a generalist, coded for a number of potential toxins, it can decide for example that grass pollen and cat dander are antigens... and you have an allergy. Elevated production of IgE is often inherited, which is why allergies run in a family.

Migraine (Migraine Headache, Migraine Headaches, Migraines)
Not just a headache, but a disorder affecting the whole body, characterized by clearly defined attacks lasting from about 4 to 72 hours, separated by headache-free periods; progresses through five distinct phases. Prodrome: experienced by about 50% of migraineurs and starting up to 24 hours before the headache - changes in mood, sensory perception, food craving, excessive yawning, or speech or memory problems. Aura: experienced by about 15% and starting within an hour before the headache - disruption of vision (flashing lights, shimmering zigzag lines, blind spot) or sensation (numbness or 'pins and needles' around the lips or hand), or difficulty speaking. Headache: usually pulsating and occurring on one side of the head, it may occur on both sides of the head and alternate from side to side. Muscles in the neck and scalp may be tender; there may be nausea and the desire not to eat, move, see or hear. Resolution: the headache disappears and the body returns to normal. Resolution may occur over several hours during sleep or rest; an intense emotional experience or vomiting may also end the headache. Postdrome: After the headache stops, the sufferer feels drained, fatigued and tired. Muscles ache, emotions are volatile and thinking is slow.

Naturopathy (Naturopath, Naturopathic, Naturopaths)
Medical practice using herbs and other various methods to produce a healthy body state by stimulating innate defenses without the use of drugs.

Polyp (Polyps)
A usually nonmalignant growth or tumor protruding from the mucous lining of an organ such as the nose, bladder or intestine, often causing obstruction.

Protein (Proteins)
Compounds composed of hydrogen, oxygen, and nitrogen present in the body and in foods that form complex combinations of amino acids. Protein is essential for life and is used for growth and repair. Foods that supply the body with protein include animal products, grains, legumes, and vegetables. Proteins from animal sources contain the essential amino acids. Proteins are changed to amino acids in the body.

Rheumatoid Arthritis
A long-term, destructive connective tissue disease that results from the body rejecting its own tissue cells (autoimmune reaction).

Ulcerative Colitis (Colitis Ulcerosa)
Ulceration of the colon and rectum, usually long-term and characterized by rectal bleeding or blood in the stool, frequent urgent diarrhea/bowel movements each day, abdominal pain.

Urticaria (Hives)
Commonly known as hives, urticaria is one of the most common dermatological conditions seen by allergists. Urticaria is not just an allergic disease, however. It can be caused by metabolic diseases, medications, infectious diseases, autoimmune disease, or physical sensitivity. Traditional allergies to foods or medications as well as viral illness are frequent causes of acute urticaria which usually lasts only a few hours but may last up to 6 weeks. Chronic urticaria (lasting more than 6 weeks) is more complex, given the vast number of potential triggers. Symptoms include sudden onset; initial itching; then swelling of the surface of the skin into red or skin-colored welts (wheals) with clearly defined edges; welts turn white on touching; new welts develop when the skin is scratched; usually disappear within minutes or hours. Welts enlarge, change shape, spread or join together to form large flat raised areas.

Yeast
A single-cell organism that may cause infection in the mouth, vagina, gastrointestinal tract, and any or all bodily parts. Common yeast infections include candidiasis and thrush.
