Food Chaining

1. Food chaining: A proven method to expand picky eaters' diets

Food chaining is an effective treatment approach because it is based on your child's natural preferences and builds upon her successful eating experiences.

What is food chaining? It's a systematic approach to expanding a child's diet by gradually introducing new foods that are similar to those they already accept. The process involves:

• Analyzing the child's core diet for patterns in taste, texture, temperature, and consistency
• Creating food chains that introduce new foods with similar properties to accepted foods
• Using a rating scale to track the child's reactions and adjust the food chain accordingly

Benefits of food chaining:

• Reduces anxiety and resistance to new foods
• Builds on the child's existing preferences
• Allows for gradual and natural expansion of the diet
• Can be customized to each child's unique needs and sensitivities

Food chaining is typically developed by speech therapists, occupational therapists, or dietitians trained in analyzing core diets and creating appropriate food chains. The process can be as structured or unstructured as needed, depending on the child's needs and family situation.

2. Identify underlying medical issues before addressing feeding problems

We believe that children refuse to eat for a reason, and a legitimate medical condition may be affecting your child's desire or ability to eat.

Common medical issues: Various health conditions can contribute to feeding problems, including:

• Gastroesophageal reflux disease (GERD)
• Eosinophilic esophagitis (EoE)
• Delayed gastric emptying
• Food allergies or intolerances
• Chronic constipation

Steps to identify medical issues:

1. Consult with a pediatrician for a thorough medical evaluation
2. Consider referrals to specialists (e.g., gastroenterologist, allergist) if needed
3. Undergo appropriate diagnostic tests (e.g., upper GI X-ray, endoscopy, pH probe)

Addressing underlying medical conditions is crucial before implementing a food chaining program. Treating these issues can often alleviate some feeding problems and create a foundation for successful dietary expansion.

3. Ensure proper nutrition and recognize potential food allergies

The narrower your child's diet, the more likely it is that he is missing some essential nutrients.

Nutritional assessment: A pediatric dietitian plays a crucial role in evaluating a child's nutritional status and developing a plan to meet their needs. Key aspects include:

• Analyzing current food intake and identifying nutritional gaps
• Recommending appropriate supplements if necessary
• Monitoring growth and weight gain

Food allergies: Recognizing and addressing food allergies is essential for safe dietary expansion. Common signs of food allergies include:

• Hives, rash, or eczema
• Swelling of lips, face, or throat
• Gastrointestinal symptoms (e.g., vomiting, diarrhea)
• Anaphylaxis (in severe cases)

Proper diagnosis of food allergies typically involves:

• Elimination diets
• Skin prick tests
• Blood tests (RAST)

Working with a pediatric dietitian and allergist can help ensure that a child's nutritional needs are met while safely avoiding allergens and expanding their diet.

4. Assess oral motor skills and swallowing abilities for safe eating

Swallowing is a complex, three-stage process. These three stages are controlled by nerves that connect the digestive tract to the brain.

Oral motor skills assessment: A speech therapist evaluates a child's ability to use the muscles of their mouth for eating and drinking. This includes:

• Lip closure and tongue movement
• Chewing patterns
• Ability to manipulate food in the mouth

Swallowing evaluation: The speech therapist assesses the child's swallowing function, which may involve:

• Observing meals and snacks
• Using cervical auscultation to listen to swallowing sounds
• Conducting modified barium swallow studies or fiberoptic endoscopic evaluations of swallowing (FEES)

Based on these assessments, the speech therapist can recommend appropriate feeding techniques, utensils, and food textures to ensure safe and efficient eating. They may also develop oral motor therapy programs to improve a child's feeding skills.

5. Understand sensory processing disorders and their impact on feeding

Sensory processing is vital to our functioning because it's the foundation upon which develop all of our motor skills, social skills, and our capacity to learn and perform complex actions.

Sensory processing disorders: These conditions affect how a child interprets and responds to sensory input, including taste, texture, smell, and appearance of food. Common types include:

• Sensory modulation disorder (over- or under-responsive to sensory input)
• Sensory discrimination disorder (difficulty distinguishing between similar sensory inputs)
• Sensory-based motor disorders (affecting movement and coordination)

Impact on feeding:

• Aversion to certain textures, tastes, or smells
• Difficulty tolerating mixed textures
• Preference for foods with consistent sensory properties
• Gagging or vomiting in response to certain foods

An occupational therapist can assess a child's sensory processing abilities and develop strategies to address sensory-based feeding issues. This may include sensory integration therapy and gradual exposure to new sensory experiences related to food.

6. Address behavioral issues and create positive mealtime experiences

Anxiety will reduce your child's appetite. Tension in your child's body can affect his swallow.

Behavioral strategies:

• Use positive reinforcement to encourage desired mealtime behaviors
• Avoid pressuring or forcing a child to eat
• Establish consistent mealtime routines and expectations
• Create a calm and supportive eating environment

Reducing mealtime anxiety:

• Allow children to explore food without pressure to eat
• Involve children in meal preparation and food-related activities
• Use food education and exposure to reduce fear of new foods
• Implement gradual changes to avoid overwhelming the child

A behavioral psychologist can help develop personalized strategies to address negative mealtime behaviors and create a more positive eating experience for the entire family.

7. Implement food chaining strategies to introduce new foods gradually

Slowly but surely, you can continue to expand your child's food repertoire until he is consistently eating a healthy, balanced diet with a wider taste or texture preference.

Food chaining process:

1. Analyze the child's core diet and preferences
2. Create food chains based on accepted foods
3. Introduce new foods with similar properties to accepted foods
4. Use rating scales to track progress and adjust the food chain
5. Gradually expand to foods with slightly different properties

Tips for successful food chaining:

• Start with small changes to avoid overwhelming the child
• Offer new foods alongside accepted foods
• Allow the child to explore new foods without pressure to eat
• Involve the child in food preparation and selection when possible
• Be patient and consistent in offering new foods

Food chaining is a gradual process that may take weeks or months to show significant results. Consistency and patience are key to success.

8. Develop pre-chaining programs for infants with feeding difficulties

Pre-chaining is a therapeutic technique designed to prevent infants (age birth through one year) who show early signs of a feeding problem from developing a full-blown feeding disorder.

Pre-chaining goals:

• Develop foundational feeding skills
• Improve oral motor function
• Enhance sensory tolerance for food and feeding-related stimuli

Key components of pre-chaining:

• Therapeutic tastes (e.g., dipping pacifier in breast milk or formula)
• Oral motor exercises and stimulation
• Sensory exposure to food smells, textures, and appearances
• Gradual introduction of age-appropriate feeding skills

Pre-chaining programs are typically developed and supervised by speech therapists and occupational therapists. They are particularly beneficial for infants with medical conditions that interfere with normal feeding development or those showing early signs of feeding aversion.

9. Tailor food chaining approaches for children with special needs

Every child is different and needs his or her own unique treatment program to be successful.

Special considerations for children with:

Autism:

• Address sensory sensitivities
• Use visual supports and schedules
• Incorporate food education and exploration

Down syndrome:

• Address oral motor weaknesses
• Consider medical complications (e.g., heart defects)
• Tailor approach to cognitive abilities

Visual impairment:

• Emphasize other sensory experiences with food
• Use tactile cues and contrasting textures
• Provide clear verbal descriptions of food

Cerebral palsy:

• Address positioning and support needs
• Consider swallowing difficulties
• Tailor food textures to motor abilities

Food chaining for children with special needs often requires collaboration between multiple specialists, including occupational therapists, speech therapists, and medical professionals. The approach should be tailored to each child's unique challenges and abilities, with a focus on creating positive, successful eating experiences.
