Chapter 15
One survey of U.S. schoolchildren revealed that on the day of the survey,
- 40% of the children ate no vegetables, except for potatoes or tomato sauce, - 20% ate no fruits. - Less than 20% of school-age girls consume adequate calcium.
Solid food readiness
- reaching a weight of at least 13 pounds - frequency of feeding, such as consuming more than 32 ounces (1 liter) of formula daily or breastfeeding more than 8 to 10 times within 24 hours. - Considerations: - nutritional need - physiological readiness - physical capability - allergy prevention - Waiting about 7 days between the introduction of each new food is important because it can take that long for evidence of an allergy or intolerance to materialize (diarrhea, vomiting, a rash, or wheezing) - Sample diet starting 6 mos: Week 1: Rice cereal Week 2: Add strained carrots Week 3: Add applesauce Week 4: Add oat cereal Week 5: Add cooked egg yolk Week 6: Add strained chicken Week 7: Add strained peas Week 8: Add plums
Growth charts
- represent 90-96% of children
Teen iron needs
- 10% of teenagers have low iron stores or iron-deficiency anemia - Iron-deficiency anemia sometimes appears in boys during their growth spurt, but adolescent females are at greatest risk of deficiency due to heavy menstrual flow and poor dietary intake.
Infant water needs
- 3 cups (700 to 800 milliliters) - Met by breast milk - Even in hot weather, the American Academy of Pediatrics does not recommend supplemental water or juice during the first 6 months. Excess water can cause hyponatremia in infants. It is important to remember that excessive fluid can be harmful, especially to the brain. - Dehydration s/s: More than 6 hours without a wet diaper Dark-yellow or strong-smelling urine Unusually tired and fussy Dry mouth and lips Absence of tears when crying Eyes and soft spot on the head appear sunken Cold and splotchy hands and feet
Infant fat needs
- 30 grams of fat per day - 15% or 5g essential fatty acids - Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids that have important roles in infant development of nervous system, esp. brain & eyes
A healthy range of fat intake is ______ to ______ of total calories for ages 1 to 3 years and ________ to _________ of total calories for older children and teenagers.
- 30% to 40% - 25% to 35%
Infant carb needs
- 60 grams per day at 0 to 6 months - 95 grams per day at 7 to 12 months.
Infant protein needs
- 9 grams per day for younger infants - 11 grams per day for older infants - half of total should be essential amino acids
Autism Spectrum Disorder and nutrition in children
- ASD commonly has GI issues associated incl. nutrient absorption issues - popular intervention: gluten-free, casein-free (GFCF) diet, which eliminates all wheat, barley, rye, and milk products - At this time, the American Academy of Pediatrics does not endorse any specific diet as a treatment for autism. - Other popular therapies for ASD include supplementation with probiotics, vitamins B-6 and B-12, folic acid, magnesium, and omega-3 fatty acids.
Infant Formula Safety
- All containers and utensils used to prepare formula should be washed with hot, soapy water and thoroughly rinsed with clean water before use. It is not necessary to boil the containers and utensils prior to use. - Use cold water to prepare infant formula. - If well water will be used to make infant formula, it should be tested regularly for contaminants, such as naturally occurring nitrates, which can lead to a severe form of anemia (especially among babies younger than 1 year). - If microbial contamination of well water or municipal tap water is a concern, water should be brought to a rolling boil (for 1 minute) and then cooled to room temperature (for up to 30 minutes) before use in formula preparation. - Some pediatricians recommend boiling (then cooling) the water to be used in formula preparation for infants up to 6 months of age, regardless of reports about water safety. - The American Dental Association does not recommend that formula be mixed with bottled "nursery water," which can be found alongside infant formula in most supermarkets, to limit risk of tooth discoloration from high fluoride levels. - To warm a bottle of formula, run hot water over it or place it briefly in a pan of simmering water. Infant formulas should not be heated in a microwave oven because hot spots may develop, which can burn the infant's mouth and esophagus. - Refrigerating prepared formula for 1 day is safe. - However, formula left over from a feeding should be discarded because it will be contaminated by bacteria and enzymes from the infant's saliva.
failure to thrive
- BMI < 5th percentile - 5-10% of babies - 80% have no apparent reason - reasons: - improper development of the mouth or digestive tract - problems with breastfeeding - nutrient absorption issues like celiac - CV/lung issues - outcomes: poor physical growth, impaired mental development, and behavioral problems.
Suggestions for solid food
- Build to a variety of foods. - Pay attention to your infant's appetite to avoid overfeeding or underfeeding. - Infants need fat - Choose fruits, vegetables, and grains, but do not overdo high-fiber foods. - Use sugars in moderation - Skip heavily seasoned and processed foods. - Give foods with Fe, Zn, Ca
Childhood Nutrient Needs
- Carbohydrates 130 grams per day to supply energy for the central nervous system and prevent ketosis - Protein 13 to 19 grams per day (ages 1 to 3) 34 to 52 grams per day (older children) - Fat 5 grams (minimum) per day of essential fatty acids 30% to 40% of total kcal (ages 1 to 3) 25% to 35% of total kcal (older children)
Breakfast
- Eating breakfast in general is linked to better intakes of vitamin A, vitamin C, calcium, iron, and fiber. - Instead of conventional breakfast foods, parents can offer leftovers from dinner, such as pizza, spaghetti, soups, yogurt topped with trail mix, chili with beans, or sandwiches. - For lasting energy and satiety, combine traditional carbohydrate-rich breakfast foods with a source of protein, such as low-fat cheese, nuts, or eggs.
Do not feed
- Excessive infant formula or human milk after 6 mos - Foods that tend to cause choking like hot dogs, hard or gummy candies, whole nuts, grapes, coarsely cut meats, raw carrots, popcorn, and peanut butter. - Potential food allergens before 4 months of age. Cow's milk, egg whites, peanuts, tree nuts, soy, and wheat - Cow's milk, especially low-fat or fat-free cow's milk (before age 2). - Goat's milk - Excessive fruit juice - Sources of foodborne illness - Excessive supplements
Caffeine and kids
- For children, the American Academy of Pediatrics advises limiting caffeine intake to 100 milligrams per day, if used at all - concerns over neural/CV development - negative effects of caffeine at any age are gastrointestinal distress, sleep disturbances, anxiety, increased blood pressure, and irregular heartbeat
Childhood sodium needs
- High intakes of fast foods and highly processed foods elevate sodium intakes to about 1000 milligrams per day more than preschoolers need. - lower sodium intake by limiting salt added during cooking and at the table, by cutting back on use of highly processed foods, by rinsing canned beans and vegetables before cooking, and by encouraging consumption of fruits, vegetables, and whole grains in place of prepackaged snacks.
Lead poisoning
- In the US, nearly half a million children between the ages of 1 and 5 have unacceptably high blood lead levels. - Short term effects: gastrointestinal distress, lack of appetite, irritability, fatigue, and anemia. - long term effects: devastating effects include intellectual and behavioral impairments and increased risk for several chronic diseases in adulthood.
infant mineral needs
- Iron, Fluoride, Zinc, Iodine (Zn & I usually sufficient in milk/food) - Fe: iron-deficiency anemia - if food sources of iron are not part of the infant's dietary pattern, body iron stores will be depleted by about 6 months of age. - American Academy of Pediatrics recommends that exclusively breastfed infants should receive iron supplements starting at 4 months of age and continuing until dietary sources of iron are introduced. - fluoride: low first 6 mos - fluoride supplementation is not advised before 6 months of age - after 6 mos, maybe supplement if sources insufficient
Childhood Iron needs
- Iron-deficiency anemia affects 16% of toddlers and about 5% of preschoolers. - RDA for iron is 7 milligrams per day for children ages 1 to 3 and 10 milligrams per day for children ages 4 to 8
Infant vitamin needs
- K, D, B-12 particularly important - K: clotting - Newborn infants have low levels of vitamin K because (1) limited amounts of this vitamin are transferred from the mother to the fetus during gestation; (2) breast milk is not particularly high in vitamin K; and (3) newborn infants lack the intestinal bacteria that synthesize vitamin K. Infant vitamin K deficiency can lead to a rare but potentially fatal bleeding problem. To prevent hemorrhage, vitamin K is routinely given by injection to all infants at birth. - D: bone health, immune function, and chronic disease prevention - American Academy of Pediatrics recommends that all infants and children consume 400 lU vitamin D per day starting soon after birth - toxicity is possible if intake exceeds 1000 IU per day. - B-12: anemia, failure to thrive, and irreversible damage to the nervous system
Teens calcium & vit. D needs
- Less than 10% of girls and less than 25% of boys meet recommendations for calcium intake. - one in five children is deficient in vitamin D. - Calcium requirements for 14- to 18-year-old girls and boys are 1300 milligrams per day—higher than during any other time of life. - Three servings per day from the dairy group are recommended for all teenagers and young adults to meet calcium needs. (Nondairy sources of calcium include almonds, legumes, some green vegetables, and fortified foods)
Teen growth
- Most girls begin a rapid growth spurt between the ages of 10 and 13 (Early-maturing girls may begin their growth spurt as early as age 7 to 8) - most boys experience rapid growth between the ages of 12 and 15 (early-maturing boys may begin growing by age 9 to 10). - Nearly every organ and bone in the body grows during this adolescent growth spurt. - Girls gain about 10 inches (25 centimeters) in height, - boys gain about 12 inches (30 centimeters). - Girls tend to accumulate both lean and fat tissue, whereas boys tend to gain mostly lean tissue. - This growth spurt provides about 50% of ultimate adult weight and about 15% of ultimate adult height - Teenage girls need 1800 to 2400 kcal per day - teenage boys require 2200 to 3200 kcal per day
Childhood Obesity concerns
- Only about one-half of children are getting the recommended 60 minutes of exercise per day. - children now engages in 7 hours per day of screen time, on average. - American Academy of Pediatrics recommends a limit of 1 hour per day of screen time for entertainment purposes for children 2 to 5 years of age. - Moderation in calorie intake is important. High-calorie foods, such as sugar-sweetened soft drinks and whole milk, should be limited. The focus should be on more vitamin- and mineral-dense foods and healthy snacks. - If weight loss is necessary in younger children, it should be gradual, about 0.5 to 1 pound per week. - American Academy of Pediatrics now recommends universal blood lipid screening for all children around the ages of 9 to 11. - American Heart Association recently released guidelines for children to limit added sugar intake to 25 grams per day. (This is quite a reduction from the average 80 grams of added sugars consumed by children and adolescents per day)
Childhood Calcium needs
- RDA for calcium for ages 1 to 3 is 700 milligrams per day. Between the ages of 4 and 8, calcium needs increase to 1000 milligrams per day. - diets of children fall short of the RDA for this important nutrient. - Two cups per day of milk will help toddlers and preschoolers meet their requirements for bone-building nutrients. Children up to 2 years of age should drink whole milk because they need the extra fat for energy, but after 2 years of age, reduced-fat or fat-free milk is preferred.
Beverages
- The fluid needs of school-age children range from approximately 1½ to 2½ liters per day, depending on age and gender. - 135% increase in sugar-sweetened beverage consumption has paralleled the threefold rise in childhood obesity since the 1970s. - 100% fruit juices, which are perceived by many to be an important source of vitamin C and potassium for children, have been linked to obesity, fatty liver, and metabolic syndrome.
head circumference
- a means of tracking brain growth - small head circumference could also be a result of malnutrition, infection, impaired mental development, or maternal substance abuse during pregnancy. - abnormally large measurement may be a sign of a tumor or fluid on the brain.
Potential side-effects for vegetarian children
- developing iron-deficiency anemia - deficiency of vitamin B-12 - rickets from a vitamin D deficiency.
When children refuse to eat
- have them sit at the table for a while - if they still are not interested in eating, remove the food and wait until the next scheduled meal or snack. - instead of giving attention to negative behaviors, focus on positive behaviors when they occur. Praise a child for trying something new.
Effects of iron-deficiency anemia later in life
- impaired cognition - behavioral problems - impaired motor development
Feeding babies
- it is important to burp an infant during feeding (every 1 to 2 ounces) and again at the end of the feeding. Spitting up a bit of milk is normal at this time. - a formula-fed infant should consume about 2 1/2 fluid ounces (75 milliliters) of formula per pound of body weight each day, up to about 32 fluid ounces (960 milliliters) in one day. - hunger best gague - breastfeeding usually ~20 min
