diet and nutrition in childhood Flashcards
What is the ideal food for babies?
Mammalian milk for 6 months
Infant formula is the alternative
Electronic care records- 34% at 6 months and <1% at 12 months
Reduces chances of obesity, diabetes and infections
Reduces chances of breast cancer in mothers
Even 3 months go a long way
What should the maternal diet be?
Fat deposits- energy store for feeding
400-600kcal, 11g protein, fluid extra
Breast milk contains- carbs, fats, protein, vitamins, minerals, anti-infective agents (eg. Immunoglobulins and lysozymes)
What are contraindications to breastfeeding?
Cleft palate (indirect feeding)
Inborn errors of metabolism (eg. Galactosaemia)
HIV (antiretrovirals)
Why is formula used in lieu of other milks?
The babies rent kidneys, liver enzyme systems aren’t mature enough to digest
It’s a modified cows milk/substitute
Formula fed babies gain weight differently to breast fed babies
What should a 4-6 month infant be intaking?
Breast milk or mixture of BM+FM
Due to depleting iron stores from before birth
Rapid growth and development at this age
What should a 6-12 month infant be intaking?
Weaning process- iron needs to be included
Increased protein/vitamins/mineral uptake required
What is the healthy start scheme?
Free milk, plain fresh and frozen fruit and veg, infant formula and vitamins
For (0-4yrs) and pregnant mothers
Monthly, flexible pre-loaded card scheme
Early and close liaison w health professionals
Started in WWII
What is weaning?
Expanding diet from 6 months
Prior to this GIT too immature to digest
Kidneys couldn’t regulate high solute load
Poor neuromuscular coordination to move food back in mouth and swallow
Helps w chewing ability
How to toddlers and pre-school children interact with food?
Eating- social occasion
Enjoy copying elders
Food refusal- attention
Milk from 1 year (500ml-1l) contains Ca, riboflavin, 1/2 protein and 1/4 energy of day
Vit D- added to cereals and milk
Should have variety and avoid unhealthy snacks
Should consider potential tooth decay
Water encouraged
Shouldn’t drink excessive tea due to tannins which affect iron absorption or added sugar
What should 1-4 year olds have?
Energy dense diet needed as active and rapidly growing
Increased protein/vitamin/minerals intake
Make sure not too much fibre
What should 5+ year olds have?
Can switch to semi-skimmed instead of full fat milk
Must have regular meals esp. breakfast
No unhealthy snacking
Low fat and sugar content but sufficient energy balance to avoid weight loss
Is there child hunger in the UK?
Decline in family meals
500000 kids go to school hungry
8 million families have food poverty
What are the nutrient needs for school children?
4-18 year old
Energy and protein requirement- increases
Vit D required from sun now
11-14- protein by 50%
11-18- higher Fe for girls
15-18- Ca in boys due to rapid skeletal development
5+ 35% of energy intake from fat
How are school meals considering nutrition?
Free hot dinner
Set price meal for primary
Cafeteria for secondary
SFVS 2004- free fruit/veg a day
Lunches should provide at least one portion of fruit/veg
Menus should highlight in season fruit/veg
School food outlets provide fruit/veg (tuck shops, clubs, vending machines)
Healthy schools rating scheme- education and physical health promotion (BNF involved)
Jamie Oliver food foundation
How might adolescence affect nutrition?
Transition to adulthood
Own choices- exert independence (diets)
Weight and shape influences may lead to eating disorders
Teenage growth spurt (insatiable appetite)
~encourage carb intake esp. if v physically active
~avoid fatty/sugary snacks
Can vegetarian and vegan diets be okay for children?
Food stuffs can be bulky (not nutrient dense)
Plants- non-haem only Fe
Phytate inhibitor in nuts/legumes/whole grain cereals can reduce uptake Fe, Zn, Mg, Ca
Tannins and Ca can bind non-haem Fe
~Vit C can counter this by promoting absorption
Vit D in many animal-based sources so should be considered
Risks- growth spurts, unconventional eating habits, family isolation
What is the dietary intake required for children?
Baby- 515-920 kCal, 40% lactose sugar, 12-15g protein
Preschool- 1200-1700 kCal, 25-30% sugar, 15-19g protein, 30-35% fat
Older children- 1800-2750 kCal, 17-25% sugar, 28-55g protein, 25-35% fat
Fe needed from milk to create stores, Ca due to rickets emergence, vit D dietary til 4yrs, should supplement Vit D, Vit C for Fe absorption, wound healing and preventing scurvy
VIT A for ENAMEL, VIT D for DENTINE
Salt <1-6g per day, free sugars <5-10%
What is the diet, nutrition and the prevention of chronic diseases report?
SACN published information on children’s nutrition
Observational/experimental studies
Compromised/excessive nutrition during early life can cause long term health effects
Risk of chronic disease
What are some food policies and campaigns?
NHS 5 a day
Change4life 2009 now known as Better Health- healthier families 2021 (contains Start4Life)
PHE- action on childhood obesity 2016/2018
PHE- 2 snack limit 2018
Sugar tax 2018
PHE- 20% less calorie content by 2024
London Transport 2019- ban junk food ads
Academy of Med Royal Colleges- less TV ads after 9pm and less fast food near schools
How much sugar a day?
<2- 13g <3- 15g 4-6yrs- 19g 7-10yrs- 24g 11+yrs- 30g
Too much sugar- harmful fat, heart disease, type 2 diabetes, cancer, tooth decay
What are some nutritional organisations?

2007- health service for England
National Diet and Nutrition Survey, started 2008- rolling programme, happens every year
~food consumption, nutrient intakes and nutritional status
~1.5+ years
~commissioned by FSA
~socio-demographics, physical measurements, age and gender
~1000 individuals (500 adults, 500 kids)
~compares w recommendations and trends
How is data collected for the NDNS?
Interviews, diet diaries, blood, urine
Up to 3 years genders combined then separated

2015/16- free sugars and fibre now monitored
2016- physical activity from 16+
2019/20- intake 24, online 24hr diet diary (over 4 non-consecutive days)

BNF reported a summary
What results have been collected from the NDNS?
In children-
Sugar sweetened soft drinks have reduced but still too high and main contributor to free sugar intake

Saturated fat too high
Vitamins and minerals are less than recomm however now meet
Fibre intake and oily fish below recomm

Varied diet
More than before breast fed but not for long
Fruit/veg lower in low socioeconomic classes
Energy exceeded in 75% boy and 76% girls
Protein above RNI
Na 181% of RNI for 12-18 months
How can habits be changed?
Slowly Advertising Knowledge, attitude, behaviour Environment, access Diet diaries The whole family
