26
Q

What are the effects of excess sorbitol in diet of the baby (2)?

A

alcohol derivative of glucose, poorly absorbed -> travel to colon, exert osmotic effect -> diarrhea

carb malabsorption (sorbitol or too much fructose) will cause gas (bacteria produced) -> intestinal pain -> colic

27
Q

What types of protein foods are not suitable for babies?

A
deli meats: high salt and nitrates
large fish (mercury), smoked fish, raw fish (parasites)
soft tofu: high in water, so lower protein/Fe

harmful fats (shortening, hydrogenated oils)
sugar (all types!)
salt
sugar substitutes

29
Q

What drink should be limited and why (2)? If given, what type is preferable?

  • respect: allow for food preference, allow for caution towards new food
  • no coercion, eat until satisfied
  • small portions (less intimidating)
  • relaxed and casual
  • offer balanced variety
  • avoid distraction
  • serve HEALTHY dessert only when everyone is finished
35
Q

How should new foods be introduced to children (5), to avoid what potential issues? (2)

A

avoid rejection/allergies:

introduce @ beginning of meal (hungry)
small portion (tbsp per year age)

1 new thing at a time, no mixing
consider texture (crunchy is more acceptable)
36
Q

younger: smaller, more frequent feedings
older: larger portions, 3 meals + snacks

37
Q

What foods should be limited/avoided in young children? (3)

A

choking hazards: round, gummy, smooth, sticky foods
(should cut, debone, etc; supervise!)

honey: botulinum spores; may germinate in stomach (low pH) -> botulism

Caffeine, sweets, salt

38
Q

What could result from feeding an infant/young child honey?

A

botulinum toxin poisoning

SIDS, resp distress, decreased feeding, constipation, weakness

39
Q

___ deficiency is the most preventable nutrition deficiency in kids, and the greatest risk is in ______. It is associated with: (2)

A

iron
children <5yr
high cow milk intake (low iron), lead exposure

40
Q

How is cow milk associated with iron deficiency in children? (2)

A

displaces iron rich foods if more than 2-3 cups per day

if given too early -> microscopic GI bleeding -> further iron losses

41
Q

How can the absorption of iron be improved?

A

Increased intake of vit C (leafy greens, fruits) -> take with iron source

42
Q

how is lead and iron absorption related?

A

use the same absorption receptor (DMT1)
will compete competitively!
-> more lead -> less iron absorbed
or: very little iron -> more susceptible to lead

43
Q

lead exposure can come from: _____

What are the negative health effects?

A

food, air, pipes, cans, dust, paint, pollution, etc
- lower iron absorption
interferes with iron-dependent processes (less heme synthesis)

44
Q

Iron deficiency can lead to ______. What are the effects of this condition?

A

hypochromic microcytic anemia (small pale cells)

lack of energy, slow wt gain, poor cognitive performance, impair psychomotor performance, impair renal tubule function

45
Q

What are the differences in dietary fat recommendations as children age?

A

preschool/childhood: do NOT limit fat; focus on NUTRITIOUS food choices

early adolescence: energy intake adequate to SUSTAIN GROWTH, gradually lower fat intake

no more linear growth: <35% of diet should be fat (adult AMDR)

46
Q

Why is a low fat diet NOT recommended for children?

A
  1. does not improve serum cholesterol long-term
  2. micronutrient deficiencies (Ca, Zn, VitA, B2)
  3. growth stunting (low protein, Ca, Zn)
  4. predisposition to eating disorders
47
Q

How does a low fat diet contribute to micronutrient deficiencies?

A

tends to be low in animal products
-> more complex carbs -> more fibre -> binds to minerals

-> less Ca intake, vit A, vit B2, poorer absorption of fat soluble vitamins

48
Q

In quebec, the nutrient most frequently deficient in children is:

A

Ca

49
Q

The most common complaint by parents of young kids is ______. This could be due to issues with the infant: _______ or issues with the parent: ________.

A

feeding problems

infant: colic, diarrhea, constipated, refusal to eat
parent: anxiety, ill mother, breast-feeding issues

50
Q

Refusal to eat in children is associated with: (4)

A

failure to thrive
behaviour problems
impaired growth
recurrent infections

51
Q

Can the effects of feeding issues as a young child be reversed?

A

4yrs +: catch up growth is possible; but feeding difficulties can persists, may be hyperactive

52
Q

The diagnostic criteria for feeding disorder:

A

no underlying mental or medical issue
no wt gain/loss for >1month
no lack of available food
< 6 yrs age

53
Q

Define “failure to thrive:”

A

not disease or disorder: SIGN OF UNDERNOURISHMENT
downward deviation from normal growth curve for age/gender
(significant percentile drop, or in very low percentile: 3-5%)

54
Q

What is the usual cause of failure to thrive, and what are the effects?

A

refusal to eat (mostly nonorganic cause)
(but can have organic or nonorganic causes)

effects: delayed social/motor/language skills
may need hospitalization

55
Q

The organic vs nonorganic causes of failure to thrive:

A

organic (from child itself): cong. heart defect, malabsorption, infection, anemia, heart/renal/endocrine problem, intellectual delay, parasites, etc

nonorganic (external): not enough food ($, neglect, distorted health belief), eating too little (premature, dev delay, autistic, behaviour problems, bad relationship w/ caregiver)
*no underlying disease: 80% of cases!

56
Q

Compare stunting vs wasting:

A

stunting: low HEIGHT: severe prolonged malnutrition
wasting: low WEIGHT: acute malnutrition (most sensitive indicator; first to drop)
* both falling together is primary disorder of growth

57
Q

the 3 patterns of failure to thrive:

A
  1. small head circumference; wt/ht <5th percentile
    (intellectually handicapped; difficult to feed)
  2. normal HC, normal ht, LOW WT
    (malabsorption, chronic disease, allergies)
  3. normal HC, LOW WT, VERY LOW HT
    (malnutrition from poverty, behaviour problems; deficient in essential nutrients/calories)
58
Q

How might organic and nonorganic causes of failure to thrive be connected?

A

usually both involved;

organic cause -> baby less willing to eat -> struggle with caregiver to feed -> poor relationship (inorganic)

59
Q

The ___ the child, the greater the risk related to failure to thrive

What are the risks associated with nonorganic FTT?

A

younger

< 1 yr -> risk of cognitive delay
< 6 month -> (max period of brain dev) -> max risk of problems

60
Q

The prognosis of nonorganic FTT:

A

with treatment, can stabilize wt > 3rd percentile

may still have problems with behaviour associated with eating

61
Q

extreme FTT treatment may require:

A

doctor, social worker, dietician, occ. therapist, psychologist, speech therapist, specialists, etc

may need hospitalization, tube feeding (1.5x cal per day), medical/psych/social support
