Lactose intolerance ‘trend’ is now affecting babies: Prescriptions for sugary, dairy-free infant formula triple in UK in a decade
- Newborns drank nearly 11million litres of expensive formulas in England in 2018
- The figure was 2.8 times more the amount prescribed to under-ones in 2007
- Dr Robert Boyle claimed the figures suggest the formulas are over-diagnosed
The ‘dairy-free’ trend popularised by millennials in recent years is now affecting babies, experts have warned.
There has been a massive spike in the number of infants prescribed special formula, which is often far more sugary than milk-based products.
Experts said the problem is there are much higher rates of children being diagnosed with a milk allergy than would be expected.
They warned the rise in special formula use could promote obesity and tooth decay in young children.
Researchers from Imperial College London analysed the prescriptions of specialised infant formula in England, Norway and Australia.
Rates in England are twelve-fold higher than what would be expected for the number of children with milk allergies, they found.
Prescribed amounts of specialised formula for infants rose three-fold in England from 2007-2018, with similar trends in other regions of the UK, they discovered.
Co-author Dr Robert Boyle, from Imperial, claimed the rise may have been caused by ‘formula industry marketing’.

Mothers are urged to breastfeed, if possible, in order to give their infants the maximum dose of nutrients.
Bottle-feeding can be costly for many parents struggling to cope with the financial burden of a new baby.
Formula milk also has varying levels of nutrients, decided by the provider.
And it is often not easy for babies to digest.
However, babies who consume both breast milk and formula may not get enough vitamin D and still need drops or mothers who take supplements.
Many women who breastfeed incorrectly believe that this gives babies all the nutrients they need, said Dr. Carol Wagner of the Medical University of South Carolina in Charleston.
Amounts more than doubled in Norway between 2009 and 2020, and trebled in Australia from 2001-2012.
Dr Boyle warned the trend could increase childhood obesity rates.
More than a quarter of under fives are overweight or obese in the UK — rising to four in ten eleven year olds. Around one-in-four five year-olds already have cavities.
Cow’s milk allergy is estimated to affect up to one per cent of under-twos.
Specialised products have been developed as alternatives to formula containing powdered milk.
The study, published in Clinical and Experimental Allergy in May, tracked national prescription data in England from 1991 to 2020 for babies in all three countries.
Researchers modelled the expected prescription rate based on assuming one per cent of all under-ones each year would require the formula.
This was compared to the actual prescription numbers across three different types of formula: soya, extensively hydrolysed formula and amino acid formula.
Total prescriptions soared 2.8-fold in England from 2007 to 2018 — with similar trends in other regions of the UK.
Amino acid formulas — which are of particular concern due to higher sugar levels — soared by 6.7 per cent in the country.
The number of all specialised formulas prescribed rose 2.2-fold in Norway from 2009 to 2020 and 3.2-fold in Australia between 2001 and 2012.
Dr Boyle said: ‘These data suggest high levels of milk allergy over-diagnosis and mark an important shift in early child nutrition.
‘Unnecessary specialised formula use may make a significant contribution to free sugars consumption in young children.’
Dr Boyle claimed the over-diagnosis ‘appears to have been fuelled by formula industry marketing activities’.
Mother’s milk contains nutrients that protect babies against infections — and even cot death. It also reduces their risk of heart disease later in life.
Dr Boyle said: ‘While specialised formula is reasonably well tolerated by most infants, and supports nutrition and growth, there are significant differences from standard formula or human breast milk.
‘In specialised formula products, the lactose naturally present in breastmilk or cow’s milk is partially or completely replaced by alternative carbohydrate sources, often free sugars such as glucose or sucrose.
‘High free sugars intake is an important risk factor for obesity and dental decay and a major public health issue.
‘Thus, it’s conceivable unnecessary use of specialised formula may have important public health consequences that have not been studied to date.’
