Nutrition Through the Lifespan Flashcards
How are macronutrient requirements different for pregnant women?
- Follow similar macronutrient distribution as non-pregnant women (50-60% CHO, 15-20% protein, 25-30% fat) with increased calorie level:
- Normal body weight = 30 kcal / kg
- >120% IBW = 24 kcal / kg
- <90% IBW = 36 – 40 kcal / kg
When are prenatal vitamins recommended for a pregnant woman?
Prenatal vitamins always recommended!
What micronutrients are recommmended for pregnancy?
-
Iron: Prevent anemia; Support fetal growth; Produce additional blood
- Lean beef/pork, whole grains, dark leafy greens
- Vitamin C improves absorption; Calcium can block absorption
-
Folic acid: Decrease risk of birth defects
- deficiency can cause spina bifida
- Fortified grains, beans, dark leafy greens
-
Calcium: Prevent bone loss/Improve fetal bone growth
- Dairy products, fortified OJ, fish with bones
- Maternal weight gain recommendations:
- Problems related to overwieght or obesity in pregnancy:
-
Maternal weight gain recommendations:
- BMI = < 18.5 ⇒ 28 – 40 lb gain
- BMI = 18.5 – 24.9 ⇒ 25 – 35 lb gain
- BMI = 25 -29.9 ⇒ 15 – 25 lb gain

- Less expensive
- Improves mother/child bonding
- Burns calories for mother
Breastfeeding: Macronutrient Management
- Mom is burning additional 200-500 kcal/day
- Eat wide variety of foods
- Focus on protein sources
- Watch signs from baby for fussiness, rashes – potential food allergy concern
What is a breastfeeding mother at risk for?
Higher risk for dehydration – additional fluids are necessary
Breastfeeding: Micronutrient Management
- Continue prenatal vitamin!
- Calcium = additional 1,000 mg/day
- Folic acid = 500 mcg/day

**Infancy Micronutrient Needs: **
- Vitamin K:
- Iron:
- **Vitamin D: **
-
Vitamin K:
- Single intramuscular prophylactic dose given at birth to infants
-
Iron:
- Breastfed infants - supplement by 6 months of age (can be in the form of food vs supplement)
-
Vitamin D:
- Breastfed infants - start supplement shortly after birth
Protein Energy Malnutrition (PEM) in Infants:
- **Kwashiorkor: **
- **Marasmus: **
- **Cachexia: **
-
Kwashiorkor:
- Edema that masks muscle wasting
- Caused by lack of adequate protein in diet
-
Marasmus:
- Wasted appearance and diminished subcutaneous fat stores
- Caused by overall lack of adequate energy intake
-
Cachexia:
- Wasting in the presence of a chronic disease
- How long should an infant be breast/formula fed?
- What is dental caries?
- Breast milk and/or formula should be the sole source of nutrition for the first 6 months of life
-
Dental caries:
- Result of use of a bottle or sippy cup while sleeping or ad lib intake while awake with liquids other than water
- Flouride supplementation is not recommended until 6 months of age
- Only required if water supply does not contain enough fluoride
GER vs GERD:
-
Gastroesophageal reflux (GER):“happy puker”
- Common in newborns
- Usually resolves with lower volume/more frequent feedings, position changes, and maturation of the infants GI tract
- Painless and not affecting the infant’s growth
-
Gastroesophageal reflux disease (GERD):
- Reflux accompanied by symptoms and complications (i.e. inadequate growth)
Infancy Recommendations:
- First Foods:
- Food Allergies:
- Juice:
- Milk:
- Water:
-
First Foods:
- Introduce around 6 months of age
- Choose first foods that help meet micronutrient and energy needs (i.e. Iron-fortified cereals and pureed meats)
-
Food allergies:
- Introduce new, single-ingredient foods no sooner than every 2-3 days to watch for possible allergic reactions
-
Juice:
- Never introduce before 6 months
- Only in an open cup
- Limit to ≤4 oz per day
-
Milk:
- Cow’s milk is not recommended until 12 months of age
- Only whole cow’s milk should be offered
- Water: No specific recommendations
Stooling Patterns for
- Breastfed infants:
- Formula-fed infants:
- How does the pattern change with age?
- Breastfed infants:
- 3-4 soft, medium-sized yellow stools per day
- Formula-fed infants:
- firmer, less-frequent, tan-colored stools
- With age, volume of stools increases but frequency decreases
What are some red flags for infant feeding problems?
- Consuming too little or too much
- Feeding too quickly or too long
- Feeding not on a typical schedule
- Not advancing to appropriate textures
- Having difficulty successfully transitioning to new textures
What are the macronutrient recommendations toddlers - adolescents?
- Carbohydrate: 50-60% of total intake
-
Protein: 10-15% of total intake
- Populations at risk: dieters, athletes who restrict intake, vegetarians, food allergies
- Fat: 25-30% of total intake
-
Fiber:
- Prevents constipation, protects against heart disease
Fiber Needs:
- Ages 6-12 months
- Children older than 2 years of age
- Ages 6-12 months→ gradually increase to 5g/day by 1st birthday
- Children older than 2 years of age→ child’s age + 5g/day (age +10g/day found to be safe)
- Why is calcium important for adolescents?
- What increases risk for low calcium levels?
- Calcium – adolescence is a critical period to achieve peak bone mass, especially in females
- At risk: low milk intake, high soda intake, low vitamin D
- What is the daily recommendation for Vitamin D?
- What are the benefits of vitamin D?
- Vitamin D – 600 IU/day needed, starting with the first day of life
- Benefits: bone health, prevention of cancer, autoimmune and infectious diseases
Iron:
- Deficiency:
- At risk:
- Heme iron sources vs. non-heme iron sources
- Deficiency: poorer cognitive performance, delayed psychomotor development
- At risk: high milk volume, poor intake of solids, dieting
- Heme iron sources (meat, fish, poultry) are better absorbed than non-heme sources (vegetables, grains)
- Ascorbic acid and heme iron sources help with absorption
Who is at risk for vitamin/mineral deficiency?
At risk populations:
- Anorexia, poor appetite, fad diets
- Chronic disease (CF, IBD, liver dz)
- Deprived, abused, neglected children
- Diet restriction to manage obesity
- FTT

What is the recommended food intake pattern for toddlers/preschoolers?
- Modeling behavior, positive feeding environment very important
- Rule of thumb: Offer 1 tablespoon of each food for every year of age for preschool children
- Be cautious about choking hazards under age 4 (hot dogs, grapes, nuts, hard candy)
- May need to eat 4-6 times/day
- Juice should be limited to 4 oz. or less/day
How does the food intake pattern change for school-aged children (6-12 years of age)?
- After-school snacks
- Fewer family meals
- Meals at friend’s houses
- Start of skipping breakfast
- Preparing their own convenience foods
What are some adolescent eating patterns?
- Frequent meal skipping (breakfast, lunch)
