Food Allergy and Intolerance in Grand Rapids, Michigan

If you or someone in your care has a severe allergic reaction (anaphylaxis), call 911 immediately. In Grand Rapids, ambulances can take you to nearby emergency departments such as Corewell Health (formerly Spectrum Health) Butterworth Hospital, Trinity Health Grand Rapids, Metro Health – University of Michigan Health, or Mercy Health.

• The person having the reaction should not stand or walk.
• Administer an adrenaline (epinephrine) injector (such as EpiPen® or Anapen®) into the outer mid‑thigh, through clothing if needed.
• If there is no improvement after 5 minutes, a second dose of adrenaline may be given.
• Use adrenaline first, then an asthma reliever inhaler if required.

Grand Rapids families, especially those managing food allergies in children, should have an emergency action plan and know where the closest emergency room is, particularly during winter when road conditions and response times can be affected by snow and ice.

Food Allergy vs Food Intolerance

Although they can cause similar symptoms, food allergy and food intolerance are medically very different.

What is a Food Allergy?

A food allergy is an immune system reaction to a normally harmless food protein (called an allergen). The body treats this protein as a threat and releases chemicals such as histamine, which cause symptoms.

Common food allergens include:

• Peanuts and tree nuts (almonds, walnuts, cashews, pistachios, etc.)
• Cow’s milk
• Eggs
• Wheat
• Soy
• Sesame
• Fish
• Shellfish

Food allergies can be mild, moderate, or severe. Severe reactions are called anaphylaxis and can be life‑threatening.

What is Food Intolerance?

Food intolerance is a chemical reaction to food, not an immune response. It does not cause anaphylaxis and usually:

• Is dose‑dependent (symptoms appear after a certain amount of the food is eaten).
• May be delayed, appearing several hours (up to 24 hours) after eating.
• Often affects the digestive system, but can cause headaches, flushing, and other symptoms.

Food intolerance is often linked with conditions seen in West Michigan patients, such as:

• Irritable bowel syndrome (IBS)
• Migraine headaches
• Chronic fatigue
• Asthma‑like symptoms in sensitive individuals

Food intolerance does not show up on standard allergy skin prick or IgE blood tests. Professional guidance from a Grand Rapids allergist or registered dietitian is important before changing your diet.

Who Gets Food Allergies?

Food allergies are increasingly common in children across the United States, including in Kent County and the Grand Rapids metro area.

• Many food allergies appear in the first year of life.
• Cow’s milk allergy is one of the most common early childhood allergies.
• Most children with cow’s milk allergy outgrow it before school age.
• Peanut allergy is more common in older children, and only about 1 in 4 will outgrow it.

Allergy can be inherited, but:

• Many children with food allergy do not have parents with food allergy.
• If one child in the family has a food allergy, their siblings have a slightly higher risk, but the overall risk is still relatively low.

Local pediatricians and allergy specialists in Grand Rapids can help families evaluate risk, especially if there is a history of asthma, eczema, or hay fever.

Symptoms of Food Allergy and Food Intolerance

Because Michigan weather brings long indoor seasons and more exposure to indoor allergens (dust, pet dander, mold), it can be easy to confuse environmental allergies with food reactions. A careful medical evaluation is essential.

Symptoms of Food Intolerance

Food intolerance symptoms can range from mild to quite uncomfortable. They often depend on how much of the food is eaten.

Common symptoms include:

• Headache or migraine
• Nervousness, tremor, or feeling “jittery”
• Sweating and palpitations (racing heart)
• Rapid breathing
• Diarrhea or loose stools
• Bloating, gas, or abdominal discomfort
• Burning sensations on the skin
• Tightness across the face and chest
• Asthma‑like breathing problems in some people
• Fatigue or chronic fatigue–like symptoms

These symptoms may overlap with other conditions common in Grand Rapids adults, such as IBS, reflux, or seasonal allergies, so a proper diagnosis is important.

Symptoms of Food Allergy (Mild to Moderate)

Mild to moderate allergic reactions can affect multiple body systems:

• Skin
  • Hives or welts
  • Itchy rash
  • Redness or flushing
• Face and mouth
  • Swelling of lips, face, or eyes
  • Tingling or itchy mouth
• Digestive system
  • Abdominal pain or cramps
  • Nausea or vomiting
  • Diarrhea

These symptoms usually appear soon after eating the trigger food—often within minutes to 2 hours.

Symptoms of Severe Food Allergy (Anaphylaxis)

Anaphylaxis is a medical emergency. It can develop rapidly and be life‑threatening.

Signs of anaphylaxis include:

• Difficult or noisy breathing
• Wheeze or persistent cough
• Swelling of the tongue
• Swelling or tightness in the throat
• Difficulty talking or hoarse voice
• Persistent dizziness or collapse
• Pale and floppy appearance in young children
• Severe stomach pain and vomiting

If you see these symptoms in Grand Rapids or anywhere:

1. Call 911 immediately.
2. Use an adrenaline (epinephrine) injector into the outer mid‑thigh.
3. Do not allow the person to stand or walk.
4. If no improvement after 5 minutes, give a second dose if available.
5. Use an asthma reliever inhaler after adrenaline if needed.

Local emergency departments in Grand Rapids are equipped to manage anaphylaxis, but early epinephrine is critical.

Common Food Allergens and Intolerances

Foods that Commonly Cause Allergic Reactions

The majority of food allergic reactions are caused by:

• Peanuts
• Tree nuts (e.g., almonds, walnuts, cashews, pistachios)
• Cow’s milk
• Eggs
• Wheat
• Soy
• Sesame
• Fish
• Shellfish (shrimp, crab, lobster, etc.)

These foods are also the most common triggers of anaphylaxis.

Foods that Commonly Cause Intolerance

Foods and substances that can trigger intolerance reactions include:

• Dairy products (milk, cheese, yogurt) – lactose intolerance or sensitivity
• Eggs (especially egg white)
• Chocolate
• Flavor enhancers such as MSG (monosodium glutamate 621)
• Food additives and preservatives
• Strawberries, citrus fruits, and tomatoes
• Wine, especially red wine
• Amines and salicylates in certain fruits, vegetables, and processed foods

In people with food intolerance:

• Symptoms may be immediate or delayed (up to 12–24 hours).
• Symptoms are often dose‑related and may not appear until a threshold amount of the food is eaten.

Finding the Cause: Diagnosing Food Allergy and Intolerance

Because symptoms can be similar, it can be difficult to tell if you have a food allergy, a food intolerance, or another condition entirely.

Steps to Identify a Food Trigger

Under the supervision of a clinical immunology/allergy specialist or registered dietitian in the Grand Rapids area, you may be advised to:

• Keep a food and symptom diary to look for patterns.
• Temporarily remove suspected foods for about 2 weeks, then reintroduce them one at a time to see if symptoms return (this should not be done if you have ever had anaphylaxis to that food).
• Have evidence‑based tests such as:
  • Skin prick tests using food extracts
  • Specific IgE blood tests

Professional organizations, such as the American Academy of Allergy, Asthma & Immunology (AAAAI) and the American College of Allergy, Asthma & Immunology (ACAAI), advise against non–evidence‑based tests that are commonly marketed online.

The Kent County Health Department and Grand Rapids Public Health resources can help connect you with local specialists and dietitians.

Treating Food Allergy and Food Intolerance

Food Allergy: Strict Avoidance

The most effective treatment for food allergy is complete avoidance of the allergen.

• Read all food labels carefully, every time.
• Learn the different names for common allergens, for example:
  • Milk protein: milk, non‑fat milk solids, cheese, yogurt, casein, caseinates, whey, lactose
  • Egg: egg, albumen, egg white, egg yolk, egg lecithin
  • Gluten: wheat, barley, rye, triticale, malt, wheat bran, some oat products
  • Soy: soybeans, soy protein isolate, hydrolyzed vegetable protein, soy lecithin
  • Salicylates and amines: found naturally in some fruits, vegetables, and processed foods

In the United States, food labels must clearly declare major allergens when they are:

• An ingredient
• Part of a compound ingredient
• A food additive
• A processing aid or part of a processing aid

Commonly declared allergens include:

• Cereals that contain gluten
• Crustacean shellfish
• Eggs and egg products
• Fish and fish products
• Milk and milk products
• Peanuts
• Tree nuts
• Sesame seeds and their products
• Soybeans and soy products
• Added sulfites at 10 mg/kg or more

Food Intolerance: Dose Management and Diet Adjustment

For food intolerance, the approach may be more flexible:

• Reducing the amount of the offending food rather than eliminating it completely.
• Avoiding the food for a period of time, then reintroducing in small amounts to see what level is tolerated.
• Working with a dietitian in Grand Rapids to ensure your diet remains nutritionally balanced.

Before you eliminate or reintroduce foods—especially for children—consult:

• Your Grand Rapids primary care provider or pediatrician
• A clinical immunology/allergy specialist
• A registered dietitian nutritionist (RDN)

Preventing Food Allergy in Children

Allergy prevention is an active area of research, and recommendations have changed over time.

Current evidence suggests:

• Pregnancy: There is no conclusive evidence that avoiding allergenic foods during pregnancy prevents allergies in children.
• Breastfeeding:
  • Exclusive breastfeeding for the first 4–6 months appears to help protect against the development of some allergies in early childhood.
  • Avoiding allergenic foods while breastfeeding is not routinely recommended unless the mother has her own diagnosed food allergy.
• Infant formula:
  • Soy formula does not prevent allergies.
  • Partially hydrolyzed (“HA”) cow’s milk formulas are not recommended solely for allergy prevention.
• Introducing solid foods:
  • Introducing a variety of solid foods, including allergenic foods (such as peanut, egg, and dairy), around 6 months of age (but not before 4 months) is recommended, ideally while continuing to breastfeed.
  • This should be done in consultation with your pediatrician or allergist, especially if your baby is at higher risk (for example, has severe eczema or an existing food allergy).

Families in Grand Rapids can discuss personalized allergy‑prevention plans with local pediatricians at large health systems such as Corewell Health, Trinity Health Grand Rapids, and Metro Health.

Managing Severe Food Allergy (Anaphylaxis)

People considered at risk of anaphylaxis should:

• Be prescribed an adrenaline (epinephrine) injector (EpiPen® or similar).
• Carry their injector with them at all times, including to school, work, sports, and travel.
• Have a written anaphylaxis action plan developed with their doctor.
• Ensure family members, caregivers, teachers, and coaches know:
  • How to recognize symptoms
  • How to use the injector
  • To call 911 immediately in an emergency

Adrenaline injectors are designed for use by non‑medical people and are available from pharmacies in Grand Rapids with a prescription.

Factors that may increase the severity of anaphylaxis include:

• Exercise soon after eating the allergen
• Heat
• Alcohol
• The amount of allergen eaten
• How the food is prepared (e.g., roasted peanuts vs. boiled)

Food Allergy and Schools in Grand Rapids

Schools and childcare centers in Grand Rapids and across Michigan play a critical role in food allergy safety:

• Many schools have allergy and anaphylaxis policies in place.
• Teachers and staff should be trained to:
  • Recognize allergic reactions
  • Use epinephrine auto‑injectors
  • Call 911 and follow emergency plans

Completely banning specific foods (such as peanuts) is not usually recommended because:

• It is difficult to monitor and enforce.
• It can create a false sense of security.

A better approach is to:

• Educate staff, students, and families about anaphylaxis risks.
• Put strategies in place to minimize exposure to known allergens.
• Ensure clear communication between parents, schools, and healthcare providers.

Local school districts in the Grand Rapids area often work with the Kent County Health Department to update policies and staff training.

Living with Food Allergy or Intolerance in Grand Rapids

With proper planning and support, people with food allergies or intolerances can lead full, active lives—even through West Michigan’s long winters and busy summer festival season.

Practical Tips

• Plan ahead for dining out in Grand Rapids:
  • Inform restaurants of your allergy.
  • Ask about cross‑contact in the kitchen.
• Always carry your epinephrine injector if you are at risk of anaphylaxis.
• Wear a medical alert bracelet if you have a known severe allergy.
• Keep medications accessible at school, work, and sports.
• During winter, when respiratory illnesses and asthma flares are more common, work with your doctor to keep asthma well controlled, as this can worsen allergic reactions.
