Feeding Practices and Transitions Developmental Social Cultural Nutritional Public Health
Complementary Foods - definitions • “Any energy-containing foods that displace breastfeeding and reduce the intake of breast milk.” (AAP) • “any nutrient containing foods or liquids other than breastmilk given to young children during the periods of complementary feeding….[when] other foods or liquids are provided along with breastmilk.” (WHO) • “any foods or liquids other than human milk or formula that are fed during the first 12 months of life.” (Healthy Start Guidelines)
Complementary Foods – The Nutrition issues • When are they needed? • What nutrients and foods are important? • When is the gut ready? • What about allergies? • What about juice?
Developmental Changes • Oral cavity enlarges and tongue fills up less • Tongue grows differentially at the tip and attains motility in the larger oral cavity. • Elongated tongue can be protruded to receive and pass solids between the gum pads and erupting teeth for mastication. • Mature feeding is characterized by separate movements of the lip, tongue, and gum pads or teeth
Development of Infant Feeding Skills • Birth • tongue is disproportionately large in comparison with the lower jaw: fills the oral cavity • lower jaw is moved back relative to the upper jaw, which protrudes over the lower by approximately 2 mm. • tongue tip lies between the upper and lower jaws. • "fat pad" in each of the cheeks: serves as prop for the muscles in the cheek, maintaining rigidity of the cheeks during suckling. • feeding pattern described as “suckling”
Analytical framework for the Start Healthy Guidelines for Complementary foods (JADA, 2004)
The Basics from AAP: Timing of Introduction of Non-milk Feedings • Based on individual development, growth, activity level as well as consideration of social, cultural, psychological and economic considerations • Most infants ready at 4-6 months • Introduction of solids after 6 months may delay developmental milestones. • By 8-10 months most infants accept finely chopped foods.
Some Issues: Foman, 1993 • “For the infant fed an iron-fortified formula, consumption of beikost is important in the transition from a liquid to a nonliquid diet, but not of major importance in providing essential nutrients.” • Breastfed infants: nutritional role of beikost is to supplement intakes of energy, protein, perhaps Ca and P. • Nutrient content of breastmilk is a compromise between maternal and infant needs. Most human societies supplement breastmilk early in life.
Foman S. Feeding Normal Infants: Rationale for Recommendations. JADA 101:1102 • “It is desirable to introduce soft-cooked red meats by age 5 to 6 months. “ • Iron used to fortify dry infant cereals in US are of low bioavailablity. (use wet pack or ferrous fumarate)

Too Early diarrheal disease & risk of dehydration decreased breast-milk production Allergic sensitization? developmental concerns Too Late potential growth failure iron deficiency developmental concerns Some Considerations in Complementary feedings
Solids: Weight Gain • Weight gain: Forsyth (BMJ 1993) found early solids associated with higher weights at 8-26 weeks but not thereafter
Solids: Respiratory Symptoms • Forsyth (BMJ 1993) found increased incidence of persistent cough in infants fed solids between 14-26 weeks. • Orenstein (J Pediatr 1992) reported cough in infants given cereal as treatment for GER.
Solids: Borrensen - (J Hum Lact. 1995) • Some studies find exclusive breastfeeding for 9 months supports adequate growth. • Iron needs have individual variation. • Drop in breastmilk production and consequent inadequate intake may be due to management errors
What foods should be avoided to reduce food allergy risk? • No restrictions if not at risk for allergy. • If strong family history of food allergy: • Breastfeed as long as possible • No complementary foods until after 6 months • Delay introduction of foods with major allergens: eggs, milk, wheat, soy, peanuts, tree nuts, fish, shellfish.
The Use and Misuse of Fruit Juice in Pediatrics - AAP, May 2001 • In the evaluation of children with malnutrition (overnutrition and undernutrition), the health care provider should determine the amount of juice being consumed. • In the evaluation of children with chronic diarrhea, excessive flatulence, abdominal pain, and bloating, the health care provider should determine the amount of juice being consumed. • In the evaluation of dental caries, the amount and means of juice consumption should be determined. • Pediatricians should routinely discuss the use of fruit juice and fruit drinks and should educate parents about differences between the two.
The Use and Misuse of Fruit Juice in Pediatrics - AAP, May 2001 • Juice should not be introduced into the diet of infants before 6 months of age. • Infants should not be given juice from bottles or easily transportable covered cups that allow them to consume juice easily throughout the day. Infants should not be given juice at bedtime. • Intake of fruit juice should be limited to 4 to 6 oz/d for children 1 to 6 years old. For children 7 to 18 years old, juice intake should be limited to 8 to 12 oz or 2 servings per day. • Children should be encouraged to eat whole fruits to meet their recommended daily fruit intake. • Infants, children, and adolescents should not consume unpasteurized juice.
The Use and Misuse of Fruit Juice in Pediatrics - AAP, May 2001 • Excessive juice consumption may be associated with malnutrition (overnutrition and undernutrition). • Excessive juice consumption may be associated with diarrhea, flatulence, abdominal distention, and tooth decay. • Unpasteurized juice may contain pathogens that can cause serious illnesses. • A variety of fruit juices, provided in appropriate amounts for a child's age, are not likely to cause any significant clinical symptoms. • Calcium-fortified juices provide a bioavailable source of calcium but lack other nutrients present in breast milk, formula, or cow's milk.
Allergies: Areas of Recent Interest • Early introduction of dietary allergens and atopic response • atopy is allergic reaction/especially associated with IgE antibody • examples: atopic dermatitis (eczema), recurrent wheezing, food allergy, urticaria (hives) , rhinitis • Prevention of adverse reactions in high risk children
Allergies: Early Introduction of Foods(Fergussson et al, Pediatrics, 1990) • 10 year prospective study of 1265 children in NZ • Outcome = chronic eczema • Controlled for: family hx, HM, SES, ethnicity, birth order • Rate of eczema with exposure to early solids was 10% Vs 5% without exposure • Early exposure to antigens may lead to inappropriate antibody formation in susceptible children.
Allergies: Prevention by Avoidance (Marini, 1996) • 359 infants with high atopic risk • 279 in intervention group • Intervention: breastfeeding strongly encouraged, no cow’s milk before one year, no solids before 5/6 months, highly allergenic foods avoided in infant and lactating mother
Allergies: Prevention by Avoidance (Zeigler, Pediatr Allergy Immunol. 1994) • High risk infants from atopic families, intervention group n=103, control n=185 • Restricted diet in pregnancy, lactation, Nutramagen when weaned, delayed solids for 6 months, avoided highly allergenic foods • Results: reduced age of onset of allergies
Allergies: Prevention by Avoidance(Zeigler, Pediatr Allergy Immunol. 1994)
The Use and Misuse of Fruit Juice in Pediatrics - AAP, May 2001
The Use and Misuse of Fruit Juice in Pediatrics - AAP, May 2001 • Fruit juice offers no nutritional benefit for infants younger than 6 months. • Fruit juice offers no nutritional benefits over whole fruit for infants older than 6 months and children. • One hundred percent fruit juice or reconstituted juice can be a healthy part of the diet when consumed as part of a well-balanced diet. Fruit drinks, however\ are not nutritionally equivalent to fruit juice. • Juice is not appropriate in the treatment of dehydration or management of diarrhea.
AAP: Specific Recommendations • Home prepared spinach, beets, turnips, carrots, collard greens not recommended due to high nitrate levels • Canned foods with high salt levels and added sugar are unsuitable for preparation of infant foods • Honey not recommended for infants younger than 12 months
Early Childhood Caries • AKA Baby Bottle Tooth Decay • Rampant infant caries that develop between one and three years of age
Early Childhood Caries: Etiology • Bacterial fermentation of cho in the mouth produces acids that demineralize tooth structure • Infectious and transmissible disease that usually involves mutans streptococci • MS is 50% of total flora in dental plaque of infants with caries, 1% in caries free infants
Early Childhood Caries: Etiology • Sleeping with a bottle enhances colonization and proliferation of MS • Mothers are primary source of infection • Mothers with high MS usually need extensive dental treatment
Early Childhood Caries: Pathogenesis • Rapid progression • Primary maxillary incisors develop white spot lesions • Decalcified lesions advance to frank caries within 6 - 12 months because enamel layer on new teeth is thin • May progress to upper primary molars
Early Childhood Caries: Prevalence • US overall - 5% • 53% American Indian/Alaska Native children • 30% of Mexican American farmworkers children in Washington State • Water fluoridation is protective • Associated with sleep problems & later weaning
Early Childhood Caries: Cost • $1,000 - $3,000 for repair • Increased risk of developing new lesions in primary and permanent teeth
What? • After 6 months most breastfed infants need complementary foods to meet DRIs for energy, iron, vitamin D, vitamin B6, niacin, zinc, vitamin E, and others • In US Iron and vitamin D need special emphasis due to prevelance of deficiency. • Little room for foods with low energy density in the diets of infants
When? • GI readiness: 3-4 months • Developmental readiness: varies, between 4 and 6 months • Nutritional needs beyond breastmilk: not before 6 months, after that varies • Need for variety and texture: within first year, order not important
Complementary Foods: Healthy Start Guidelines for Infants and Toddlers (JADA, 2004) Based on an extensive evidence-based review of current science
How • Introducing new foods • Repeated exposures may be needed • No evidence for benefit to introducing foods in any sequence or rate • Meat and fortified cereals provide many nutrients identified as needed after 6 months.
How • Safety issues: • Safe food handling for formula and expressed breast milk • Guidance about choking, lead poisoning, nonfood eating, high intakes of nitrates, nitrites and methylmurcury
How? • Establish healthy feeding relationship • Recognize child’s developmental abilities • Balance child’s need for assistance with encouragement of self feeding • Allow the child to initiate and guide feeding interactions • Respond early and appropriately to hunger and satiety cues
Provide guidance consistent with family/child’s • Development • Temperament • Preferences • Culture • Nutritional needs
