eMethods
Instructions given to participants regarding solid food introduction
EIG introduction regimen
Following normal blood test results at enrollment (complete blood count, bone, liver, renal and lipid profile
tests), the EIG infants then proceeded to introduce baby rice and/or pureed fruits or vegetables during the
first week until they were established on solid food. They then continued with these solids and additionally
introduced cow’s milk yogurt on two days of the second week. During weeks three and four of the early
introduction regimen, peanut, hard-boiled egg, sesame and white fish (cod) were introduced sequentially in a
random order with two new foods introduced per week. Finally, wheat was introduced in week five,
reflecting the guidance in place at the time the EAT study commenced on optimal timing of wheat
introduction after four months of age1
and by week six infants were ideally consuming the required amount
of all six allergenic foods each week.2
The introduction of non-allergenic foods was not restricted during this process, and the allergenic foods
could be given in combination with other foods or each other once the allergenic foods had been
successfully introduced and well tolerated.
The exact volume of allergen protein necessary to induce oral tolerance is unknown, but participants were
asked to consume the equivalent of 2g of each allergenic food protein twice each week (4g of allergen
protein per food per week). The full weekly amount for the allergenic foods therefore consisted of two small
40-60g portions of cow’s milk yogurt, three rounded teaspoons of peanut butter, one small egg (<53g), three
rounded teaspoons of sesame paste, 25g of white fish and two wheat-based cereal biscuits (e.g. Weetabix).2
SIG introduction regimen
For the SIG the criteria in eTable 7 reflect a pragmatic interpretation of the current UK status quo – i.e. an
incomplete following of the infant feeding recommendations. Thus allergenic food introduction from five
months (criterion C) by which point 75% of mothers in the Infant Feeding Survey 2010 (IFS2010)3
have
introduced solids to their baby including rusks (hard, dry infant biscuits) and yogurts and up to 300 mls per
day of cow’s milk formula consumption after enrollment (criterion D) were considered acceptable. The
volume was chosen such that the majority of milk consumed by the infant was still breastmilk. The amount
of breastmilk consumed by exclusively breastfed infants was reviewed in a recent systematic review.4 At 3-4
months of age the mean transfer volume of breastmilk was 779 (standard deviation (SD) 40) grams/day, at 5
months 827 (SD 39) grams/day, and at 6 months 894 (SD 87) grams/day.
Instructions given to participants regarding formula milk introduction
Mothers in both groups were encouraged to adhere to the World Health Organization (WHO) Global
Strategy for Infant and Young Child Feeding,3
endorsed by the UK Government,5 which recommends
breastfeeding up to the age of two years or beyond. The same document recommends exclusive
breastfeeding for the first six months. Mothers in the SIG were asked to adhere to the UK Government's
more pragmatic target of around six months exclusive breastfeeding.6
Mothers in both groups were discouraged from introducing formula milk, particularly during the key early
introduction period (up to six months) as formula milk introduction has been shown to have a deleterious
effect on breastfeeding performance.7
If they did introduce formula milk of their own volition, whilst still
breastfeeding, they were encouraged to keep the volume given as small as possible, to ensure that breast
milk remained the principal source of milk.
Monitoring of food consumption in the EAT study
An online questionnaire completed monthly until 12 months of age and every three months between 12 and
36 months of age by the infants’ parents was the main portal of communicating information about the health
and diet of the participants to the study team. Within this online questionnaire, both groups completed a food
frequency questionnaire section assessing how frequently foods including the six study allergens were being
consumed.
EIG families kept a prospective weekly diary up until one year of age and monthly thereafter to assess the
degree to which they were meeting the consumption target of 4g of each allergenic food protein per week.

For each of the last four complete weeks preceding the child’s monthly birthday and for each of the
allergenic foods, parents recorded the percentage of the recommended amount of food their child was
consuming (100%, 75%, 50%, 25% or less, not tried yet) with guidance provided on the amount of each
food constituting those percentages. This diary data was then entered into the online questionnaires.
Finally, at 6, 12 and 36 months of age parents completed a five day food diary recording in detail their
child’s diet including portion size
