Toddler Nutrition

Published on

This article was published in the November 2018 edition of NHD Magazine.


Toddlerhood (between one and three years old) is a time of rapid growth and development.

Malnutrition during these early years can lead to stunted growth, and problems with behavioural development and learning1.

Following the exposure to new tastes and feeding experiences during infancy, toddlers are continuing on their journey of food discovery. Development of biting and chewing skills also continues at this age. For example, between 18 – 24 months toddlers will begin to chew with their lips closed2.

Nutrient Intake

The results of the most recent National Diet and Nutrition Survey (NDNS) from 2014 – 2016 are outlined in table one, along with an explanation of what role these nutrients play in a toddler’s diet3-8.

Table one: Results of NDNS survey of children aged 1.5 – 3 years*

NutrientNutritional Impact for ToddlersRecommended Daily IntakeMean Intake (% of Total Energy)
Total FatProvides energy, helps the body to absorb vitamin A, D, E and K, and is important for development of the brain and nervous system. There is no defined RNI for fat for children under five.41.3 g (34.4%)
Saturated FatNot essential for health, but provides energy and has a role in cell functioning. It is recommended that toddlers avoid excess saturated fat intake to improve heart health in later life.There is no defined RNI for saturated fat for children under five.17.5 g (14.5%)
Trans FatProvides energy but a high intake in later life is associated with poor heart health. It is recommended that toddlers avoid trans fat as much as possible to improve heart health. There is no defined RNI for trans fat for children under five.0.6 g (0.5%)
ProteinImportant for growth, development and recovery.14.5g per day41.5 g (15.5%)
Total CarbohydrateNeeded to supply energy and support growth.50% of daily energy(from two years old)144 g (50.2%)
Free SugarsProvides energy, but a high intake can increase the risk of dental caries and excess weight gain.≤ 5% of daily energy (from two years old)32.6 g (11.3%)
Fibre (AOAC Method)Can help to keep bowels healthy, but too much can cause early satiety in toddlers. 15 g (from two years old)10.3 g
Vitamin AImportant for growth, immune health, skin health and improves night vision. 400 mcg413 mcg
RiboflavinNeeded for growth and development, cell function, and energy production. 0.6 mg1.28 mg
Folate (including supplements)Needed for cell and nerve function, and to avoid megaloblastic anaemia (where large blood cells can’t carry oxygen around the body well).70 mcg142 mcg
Vitamin D (including supplements)Needed to absorb calcium and avoid rickets, and is important for the immune system.10 mcg2.9 mcg
IronNeeded to avoid anaemia, which has been associated with reduced cognitive, motor, social and emotional skills in young children. 6.9 mg5.9 mg
CalciumNeeded for bone health, to avoid rickets and to build up calcium reserves for later life.350 mg718 mg
MagnesiumImportant for muscle and nerve function, and creating: bone, protein, and DNA.85 mg148 mg
PotassiumNeeded for normal cell function, fluid balance, growth and muscle function.800 mg1664 mg
IodineImportant for growth, thyroid health, and for normal development of the nervous system during childhood. 70 mcg125 mcg
SeleniumImportant for thyroid health, DNA production, boosts immunity and acts as an antioxidant. 15 mcg23 mcg
ZincNeeded for growth and immune health.5 mg4.9 mg

Sugar intake for those who were 18 months to three years old was found to be more than double the recommended limit

Only 13% of toddlers achieved a sugar intake which was below or equal to 5% of total energy. The main source of free sugar intake in this age group was found to be ‘cereal and cereal products’, with the second highest source being fruit juice and soft drinks, followed by ‘sugar, preserves and confectionery’.

One of the risks associated with excess sugar intake in children is dental caries, and 28% of 5 year olds in England are already found to have tooth decay7,13.

Fibre intake was found to be 5g below the daily recommended amount for toddlers

‘Cereals and cereal products’ being the main source of fibre, followed by ‘vegetables and potatoes’ and then fruit.

After the age of two, wholegrain foods can be gradually introduced to a toddler’s diet14. Before this, the high fibre content of wholegrains can make a toddler feel full before they have consumed enough calories and nutrients.

Although protein is an important nutrient for toddlers to consume, the overall protein intake from the NDNS appears to be very high in this group. This is worrying as this can effect bone health, kidney health and increase the risk of obesity in later life.

Another notable results of the NDNS was that iron intake was slightly low and vitamin D intake was very low in toddlers, even when intake from supplements was included.

Toddlers in the UK tend to have a good intake of iodine, however those who avoid cow’s milk are at a higher risk of deficiency as this is the main source of iodine in the UK15.

The amount of salt in a toddler’s diet should also be limited, especially as the average intake in the age group in the UK was found to be 2.3g of salt per day, which is above the recommended limit of 2g per day16.

Intake From Food Groups

The recommended portion sizes and distribution of food groups is outlined in the ‘5532-a-day’ image from the British Nutrition Foundation below17.

When the data for daily energy intake from various food groups from the most recent NDNS are compared with this, it seems that intake of starchy foods, dairy foods and protein are close to the recommended amount.

But toddlers seem to have a low intake of fruit and vegetables.

And although these are not necessary in most toddlers’ diet, they also appear to be having a regular intake of: sugary drinks, sugary snacks, and savoury snacks.

Percentage daily energy intake from various food groups:
Cereals and cereal products – 34%
Milk and milk products – 23%
Meat and meat products – 11%,
Vegetables and potato – 6%
Fruit – 6%

Remaining daily energy intake (labelled as ‘other’ in the pie chart) included:
Fish – 2%, eggs – 2%, nuts – 1% Fat spreads – 3%, sugar preserves and confectionery – 4%,
juice and soft drinks – 3% , Savoury snacks – 3%

Breastfeeding Advice

The World Health Organisation (WHO) advise that babies should be breastfed exclusively for the first six months of life, and “thereafter infants should receive complementary foods with continued breastfeeding up to 2 years of age or beyond”18

This advice to continue breastfeeding beyond twelve months is because breast milk continues to provide energy, hydration and key nutrients.

However, it is rare in the UK to breastfeed beyond 12 months19

In developing countries continued breastfeeding is linked with improved growth and a lower risk of infant mortality20.

There is not much research which has examined the effect of breastfeeding past infancy in developed countries. A relatively small study from America in 2016 found that the mothers’ breast milk in the second year of lactating had a significant increase in total protein, prebiotics (oligosaccharides) and proteins which boost immunity, as compared with mothers in the first year of lactating21. This study also found that zinc and calcium levels reduced in breastmilk in the second year of lactating, and no changes were found in lactose, fat, iron or potassium levels.

An older study also found that 448ml of breastmilk in the second year of lactation provides:22

  • 29% of energy requirements
  • 43% of protein requirements
  • 36% of calcium requirements
  • 75% of vitamin A requirements
  • 60% of vitamin C requirements
  • 76% of folate requirements
  • 94% of vitamin B12 requirements

A systematic review by Victora et al. (2016) identified an increase in tooth decay in children who were breastfed for more than 12 months. However this study also highlighted that “this should not lead to discontinuation of breastfeeding, but rather to improved oral hygiene”23.

Nutritional Supplements

In the UK, all children from the age of one to five are advised have a daily age-appropriate supplement which contains vitamin A, vitamin C and 10 microgram of vitamin D24-25.  

These can be bought in a pharmacy or supermarket, or they can be obtained on the ‘Healthy Start Scheme’ for those who are eligible.

Advice About Drinks

Water is the best drink for toddlers.

Baby bottles should be stopped by age of one, as this can become a comfort and can cause tooth decay26. Instead, drinks should be given from a beaker with a free-flow lid, and when a toddler is ready they should be encouraged to drink from an open cup26.

Milk can be given to toddlers, and it is an important source of calcium. However, toddlers should ideally have no more than two or three glasses of milk per day, depending on how many other dairy foods they eat14. This is because drinking too much milk is associated with increasing the risk of anaemia and providing excess protein27.

Full fat milk should be given until a toddler is two years old, but from the age of two the fat content of most toddler’s diet can be reduced; as long as they are growing well and have a balanced and varied diet2. Semi-skimmed milk can be given from two years old, but skimmed milk should not be offered until they are five years old2. Rice milk should not be given to children under five years, as it can contain traces of arsenic26.

Fruit juice is a good source of vitamin C, but to reduce the risk of tooth decay it needs to be diluted with one part juice to 10 parts of water for toddlers26.

Squash, ‘juice drinks’, fizzy drinks, flavoured milk, diet or reduced sugar drinks, or ‘baby drinks’ should not be offered to toddlers.

Tea and coffee are also not recommended for this age group, as these drinks can reduce the amount of iron which is absorbed from meals26.  

Fussy Eating

Infants usually start to become hesitant about trying new foods at around 18 months, this is called ‘food neophobia’2.

This is a stage where fussy eating behaviour can start to emerge and become reinforced.

To avoid fussy eating becoming a long-term problem it is best to:28

  • Establish eating routines
  • Eat together as a family to model good eating habits
  • Provide varied and balanced meals of appropriate portion sizes
  • Encourage self-feeding and messy play
  • Give praise when a new food is tried
  • Try to remain calm when food is refused

It is also important that everybody involved in taking care of the toddler (including both parents, other family members and nursery staff) are consistent in handling food refusal in an appropriate way.
