1. Looking Beyond the Basics of
Infant Nutrition
Learning Objectives
By the end of this session, physicians will
be able to:
– Identify the importance of counselling on
infant nutrition
– Recognize that optimizing infant nutrition
requires considerations beyond the basics
Such that they will:
– Consistently, proactively and confidently
counsel on optimal infant nutrition
Why do we need to counsel
on infant nutrition?
Why wouldn’t we counsel
on infant nutrition?
Why We Should Counsel on
Infant Nutrition
Growth and development are rapid in
early life1,2
Certain nutritional components are
associated with development and
health3‐6
Early nutrition counseling may:
– Help optimize development
– Provide the foundation for lifelong nutrition

6. Vitamin D:
Implications for Counselling
For nursing mothers:
– Supplement diet to achieve intake of at least
600 IU daily1
For breastfed infants:
– Daily supplement of 400 IU1
– Infants who receive limited amounts of
formula as supplemental feeds likely still
require vitamin D supplementation to meet
daily requirements
For formula fed infants:
– Formulas provide adequate vitamin D – no
further supplementation is required2

Iron: Implications for
Counselling—Breastfeeding
Full‐term breastfed infants do not require
iron supplementation1
– Breast milk is relatively low in iron, but it is
bioavailable (20‐50%)1
– Level of iron in breast milk declines over time1
Introduce solid foods as recommended at
6 months (starting with iron‐fortified
cereal)2

Iron: Implications for
Counselling—Formula Feeding
Infant formulas are iron fortified and so contain
adequate concentrations of exogenous iron1
– Higher levels required due to relatively low
bioavailability (3‐10%)1
– No additional iron supplementation is
required in full term infants2
– There is no indication for non‐iron‐fortified
infant formula

months (starting with iron‐fortified cereal)3

Results:
Primary: No significant differences between formulas in

Secondary: GOS/PDX formula was associated with:
– Higher Bifidobacteria counts than control at 60 days
and similar to breast milk fed (qPCR analysis)
– Softer stools at all time points

parents?
What could it be?
Helping Parents be Proactive in Infant Nutrition:
COUNSEL: A Mnemonic Counselling Tool
C Confirm that breastfeeding is the preferred primary source
of infant nutrition.
O Optimize the mother's nutritional intake: recommend a
balanced, healthy diet.
U Underline the importance of certain components of the
maternal diet (DHA and vitamin D).
N Never use other milks (e.g., cow, goat, plant‐based) as the
primary infant food.
S Supplement the breastfeeding infant’s diet with vitamin D,
400 IU daily.
E Educate all parents about formula feeding: choose formula
with adequate DHA & ARA levels, consider formula with
prebiotics.
L Labels: Encourage parents to read formula labels to ensure
levels of DHA & ARA proven to have an effect on health &
development.
Beyond the Basics of Infant
Nutrition
Summary
Key Learning Points from This Session (1)
Healthcare professionals need to counsel
parents on infant nutrition. Why
Wouldn't We?
Breastfeeding mothers need:
To eat a healthy diet.
Adequate DHA from diet / supplements.
To supplement the infant's diet with vitamin D.
Key Learning Points from This Session (2)
When transitioning off breast milk (or
choosing not to breastfeed):
Iron‐fortified formula is the food of choice.
Choose formula with appropriate levels of
DHA & ARA.
Consider choosing formula with prebiotics.
10. The Future of Infant Nutrition
We Are What We Eat…
Future Understanding
Nutrients can modify physiologic and
pathologic processes through epigenetic
mechanisms and thus potentially play a
role in disease prevention and maintenance
of health.
‐ Choi SW, et al. Adv Nutr 2010
(Epigenetics refers to the heritable changes in gene expression
that change the underlying DNA sequence. Examples are DNA
methylation and histone modification.)
We Are What We Eat…
Future Understanding
The human component of the total DNA
in our bodies is 0.3%1
The other 99.7% is of microbial origin1
The intestinal microbiota may be
influenced by dietary intake2,3
The human gut microbiome (the
collective community of microbes and
their total genome capacity) have been
implicated in health and disease4

or Who Are Breastfeeding

2. Health Canada Media Release (Feb 14, 2007). Health Canada advises specific groups to limit
their consumption of canned albacore tuna. Available at: www.hc‐sc.gc.ca/ahc‐
asc/media/advisories‐avis/_2007/2007_14‐‐e.php. Accessed July 20, 2010.
Types of fish to eat less often Types of fish to choose
High mercury, predatory fish
• Shark
• Swordfish
• Fresh/frozen tuna
• Marlin
• Orange roughy
• Escolar
Other fish low in mercury & high in omega‐3 fatty
acids
•Salmon
•Herring
•Shrimp
•Char
•Atlantic mackerel
•Rainbow trout
•Canned light tuna (skipjack, yellowfin, tongol)
Limit to 150 g / month1 Consume at least 150 g (2 Canada’s Food Guide
servings) per week1
Check provincial & local advisories about the safety of fish caught locally.
Consumption of canned (white) albacore tuna should be restricted to no more than
300 g (4 Canada’s Food Guide servings) per week, but no restrictions on other types of
canned light tuna2

Human Milk Oligosaccharides
Content/Composition
– 3rd largest component (5‐10 g/L mature
milk)1,2
– More than 200 human milk oligosaccharides
identified (evidence for >900)2
– Variation due to maternal genetics, lactation
stage3
Properties/Functions
– Structurally diverse; variable composition
– Digestion resistance; local and systemic
effects1
– Prebiotic – stimulates beneficial GI microbiota
– Decoy receptors – toxins, pathogens1. Bode L. J Nutr 2006;136:2127‐30.
2. Ninonuevo MR, et al. J Agric Food Chem. 2006;54:7471‐80.
3. Chaturvedi P, et al. Glycobiol.2001;11:365‐72.
13. Functions of Oligosaccharides
Prebiotics have special roles in maintaining the GI
barrier and GI immune homeostasis
Oligosaccharides found in human milk:
– Are more complex than those found in the
milk of other mammals1
– Are the most effective known prebiotics1
– Preferentially support the growth of
bifidobacteria2
Prebiotics added to infant formulas may have
clinical benefits, including lower incidence of
diarrhea and acute respiratory infection3‐5

Criteria for Prebiotic Classification:
1. Resistance to gastric acid, enzyme
hydrolysis and intestinal absorption
2. Fermentation by intestinal microflora
3. Selective stimulation of growth
(i.e., bifidogenic effect) and/or activity of
intestinal bacteria that contribute to health
