Should a parent be alarmed if their child displays these eating behaviors? • Wanting foods plain, with no sauces and not mixed together • Varying interest and lack of interest in food, with appetites that go up and down • Food jags—eating only a few foods day after day or week after week until the next food jag starts
no, these changes are considered normal for the preschool child
Toddlers
▶ 1 to 3 years old ▶ Energy and protein needs are high compared with adult needs ▶ Wide range of energy needs ◦ Velocity of growth ◦ Level of physical activity ▶ Muscle mass, bone structure, and other body tissues continue to grow rapidly ◦ Require an adequate dietary supply of protein, minerals, and vitamins ▶ Daily intake of 19 g of fiber is recommended to prevent constipation
Adolescence Physical Growth - Body Composition
▶ 12 to 18 years old ▶ The final growth spurt of childhood ◦ Increasing body size ◦ Development of sex characteristics ▶ Girls ◦ More subcutaneous fat in the abdominal area ◦ Pelvis widens ◦ Increase hip size ▶ Boys ◦ Increased muscle mass ◦ Long-bone growth
Preschool-Aged Children
▶ 3 to 5 years old ▶ Physical growth and appetite continue in spurts ▶ Food jags are common ▶ Group eating ◦ Significant means of socialization ◦ Food preferences trend toward what the group is eating ▶ A healthy eating habits developed during this time set the stage for eating behaviors throughout childhood
School-Aged Children
▶ 5 to 12 years old ▶ Generally slow and irregular growth rate ▶ Girl's development usually bypasses that of boys ▶ Parental food habits have the most influence on a child's eating behavior ▶ Screen time ◦ High-risk television behaviors are correlated to long-term negative effects on food habits and risk for obesity ▶ Peer food habits ▶ School environment
Anorexia Nervosa
▶ A serious, potentially life threatening eating disorder that is characterized by self-starvation ▶ Self-starvation can lead to deficiencies in essential nutrients and energy required for the human body to function normally
Nutritional Requirements for Growth Protein Needs
▶ As a child gets older and the growth rate slows, the protein requirements per kilogram of body weight gradually decline ▶ The protein requirements of an infant for the first 6 months of life: ◦ 1.52 g/kg ▶ The protein needs of a fully grown adult: ◦ 0.8 g/kg
Feeding for Mature Infants Breast Milk
▶ Breast milk is the ideal first food for infants ▶ When mothers are away from their infant for several hours ◦ May use manual expression or a breast pump ◦ Breast milk can be stored and frozen in sealed plastic baby bottle liners for later use
Feeding for Mature Infants Summary Guidelines
▶ Breastfeeding should be continued for at least the first full year of life ◦ It should be supplemented with a vitamin K shot at birth and daily vitamin D drops ▶ Iron-fortified formula should be used for any infant who is not breastfeeding ▶ Water and juice are unnecessary for breastfed infants during the first 6 months of life ▶ Solid foods may be introduced at approximately 6 months of age ▶ Whole cow's milk may be introduced at the end of the first year ◦ Reduced-fat or fat-free cow's milk is not recommended until after the age of 2 years ▶ Allergens (e.g., wheat, egg white, citrus juice, nuts) should not be given as the first solid foods ◦ Should be introduced soon after traditional solid foods are tolerated ▶ Honey should not be given to an infant who is younger than 1 year old ◦ Botulism spores ▶ Foods with a high risk for choking and aspiration should not be given to infants ◦ Hot dogs, nuts, grapes, carrots, popcorn, cherries, peanut butter, round candy
Feeding for Mature Infants Weaning
▶ By 6 to 9 months of age ▶ As increasing amounts of other foods are introduced
Nutritional Requirements for Growth Calcium
▶ Calcium needs are critical during the most rapid growth periods of infancy through adolescence ▶ Infancy: mineralization of the skeleton, bone growth, and formation of teeth ▶ Approximately 40% of adult peak bone mineral density is deposited during the short period of adolescence ▶ Calcium absorption, calcium deposition in bone, and calcium retention ◦ Peak just before puberty
Bulimia Nervosa
▶ Characterized by repeated episodes of binge eating and purging ▶ Binge eating: a consumption of a quantity of food that is large in size for the person and the amount of time ▶ Purging: compensatory behavior used to prevent weight gain. Methods include vomiting, laxative or diuretic abuse, enemas, fasting and excessive exercise
Growth and Development Childhood
▶ Childhood growth rate slows and becomes irregular ▶ Growth occurs in small spurts ▶ Appetites usually taper off during periodic plateaus
Nutrition Problems During Childhood Obesity - Recommendations
▶ Choose specific meal times ▶ Provide a wide variety of nutrient-dense foods rather than "junk" foods ▶ Offer an age-appropriate portion size ▶ Limit nonnutritive snacking and the use of juice or sweetened beverages ▶ Encourage children to regulate their own food intake based on intuitive eating principles ▶ Have regular family meals to promote social interaction and to role mode healthy food-related behavior ▶ Limit screen time ▶ Make physical activity a daily family affair
Feeding for Mature Infants Breast Milk Substitute
▶ Choosing a commercial infant formula ◦ Milk allergy or intolerance: Soy-based formula ◦ Allergic to cow's milk and soy-based formulas: amino acid-based formula ▶ Preparing the formula ◦ Manufacturer's instructions ◦ Refrigerate until use ◦ Bottles should be heated in a bowl of warm water (not in a microwave) ▶ Feeding the formula ◦ Never prop the bottle or leave the baby alone to feed ◦ It allows milk to pool in the mouth - choking, earache, or baby bottle tooth decay
Feeding for Mature Infants Cow's Milk
▶ Cow's milk is not recommended during the first year of life ▶ Unmodified cow's milk is not suitable for infants ◦ Too heavy a load of solutes for the infant's GI tract and renal system ▶ Children between the ages of 1 and 2 years ◦ Should not be fed reduced-fat cow's milk (e.g., skim or low-fat milk) ⚫ Insufficient energy ⚫ Lacks linoleic acid (essential fatty acid for growth found in the fat portion of the milk)
Nutritional Requirements for Growth Iron
▶ Essential for hemoglobin formation and cognitive development ▶ Infants of mothers with iron-deficiency anemia during gestation are at risk for iron-deficiency anemia at birth ▶ Iron content of breast milk is highly absorbable and fully meets the needs of an infant for the first 6 months of life ▶ Infants who are not breastfed need an iron-fortified breast milk substitute
Nutritional Requirements for Growth Water Requirements
▶ Infants required more water per unit of body weight than adults ◦ A greater percentage of the infant's total body weight is composed of water ◦ A larger proportion of the infant's total body water is in the extracellular spaces ◦ Infants have a larger proportional body surface area and metabolic rate ▶ In 1 day, an infant generally consumes amount of water that is equivalent to 10 - 15% of his/her body weight
When to Introduce Solid Food
▶ Introduce solid food at 6 months ◦ Tongue movement allows swallowing ◦ Muscle development allows infant to sit up ◦ Digestive system and kidneys have matured ◦ Less likely to develop food allergies ◦ Iron-fortified cereals are well tolerated
Feeding for Mature Infants Solid Food Additions
▶ Iron-fortified solid foods should be added at approximately 6 months of age ▶ The American Academy of Pediatrics note other signs of readiness ◦ Can the infant hold his or her head up? ◦ Does the infant open his/her mouth in anticipation of food coming his/her way? ◦ Can the infant move the food from the spoon to his/her throat to swallow? ◦ Is the infant large enough?
Premature Infants Physiologic Delays
▶ More body water, less protein, and fewer mineral stores ▶ Little subcutaneous fat to maintain body temperature ▶ Poorly calcified bones ▶ Incomplete nerve and muscle development - sucking reflexes weak or absent ▶ Limited ability for digestion, absorption, and renal function ▶ Immature liver ◦ Lack developed metabolic enzyme systems or adequate iron stores
Growth and Development Infancy
▶ Most infants double their birth weight by 6 months and they triple it by 12-15 months of age ▶ Infants generally increase their birth length by 50% during the first year and double it by 4 years of age
Adolescence Physical Growth - Bone Mineral Density
▶ Reach its peak velocity of accumulation during the preadolescent years (≈ 8 years old) through about age 20 ▶ Linear growth reaches its peak ◦ Female: 16 years of age ◦ Male: 21 years of age ▶ Balanced diet with calcium containing dairy or dairy substitutes ▶ Recommended calcium intake: 1300 mg/day ▶ Even when supplemented with calcium, bone mineral density does not reach the same level as those who consume naturally high calcium diet
Milk Content for Premature Infants
▶ The American Academy of Pediatric recommends normal feeding of breast milk to premature and other high-risk infants ▶ Mothers of preterm infants produce milk that is significantly higher in energy, carbohydrates, protein, and fat to meet the elevated needs of preterm infants
Nutritional Requirements for Growth Vitamin Supplements
▶ The American Academy of Pediatrics recognizes only 2 vitamins that are potentially needed in supplemental form ◦ Vitamin K ◦ Vitamin D ▶ Nearly all infants born in the U.S. and Canada receive a one-time prophylactic injection of 1 mg of vitamin K at birth ▶ It is recommended that breastfed infants receive oral vitamin D drops (400 IU) beginning at hospital discharge
Growth and Development Adolescence
▶ The onset of puberty begins the second stage of rapid growth ▶ Levels of growth hormone and sex hormones rise ▶ Long bones grow quickly ▶ Sex characteristics develop ▶ Fat and muscle mass increase significantly
The total daily caloric intake of an average 5-year-old child is spent in the following way
◦ Basal metabolism: 50% ◦ Physical activity: 25% ◦ Tissue growth: 12% ◦ Fecal loss: 8% ◦ Thermic effect of food: 5%
