Breastfed babies are less likely to be given sugary drinks or unhealthy snacks before the age of one, a study has claimed.
Researchers from the University of Glasgow analysed data from 2,730 parents.
Overall, they found babies who still received any amount of breastmilk at six months and beyond were more likely to have a diet that adhered to official feeding advice.
From six months old, it is recommended that babies are introduced to suitable family foods.
This begins with simple purees and gradually progresses to more textured meals and finger-sized food.
Researchers from the University of Glasgow found 15 per cent of babies who were breastfed for six months or longer were given unhealthy treats compared to 45 per cent of formula-fed babies
Current advice also suggests offering babies green and bitter vegetables early, and to avoid adding salt and sugar to foods.
Sugar-sweetened drinks and ‘treats’ such as chocolate and crisps should also be avoided until kids get older.
In the study, 15 per cent of babies who were breastfed for six months or longer were given unhealthy treats compared to 45 per cent of formula-fed babies.
Breastfed babies were also more likely to start solid food at the recommended age of six months or older.
The researchers, from the University of Glasgow, said all the links remained even after they took socioeconomic factors into account.
Lead author Dr Ada Garcia said: ‘In this study we were able to observe that diet inequalities start as early as 6-12 months old.
‘This is worrying, because eating habits are developed and established early in life, and it can be harder to change them later on.
‘Our research suggests that continuing to promote breastfeeding, where possible, may help to protecting infants’ health, along with helping to establish healthy dietary behaviours from a young age.’
The researchers also found that, of all the babies surveyed, 20 per cent were solely infant formula-fed while 48 per cent continued breastfeeding beyond six months.
Despite starting the weaning process later, infants who were still breastfed after six months ate the same number of food groups and meals as formula-fed babies, and were just as likely to self-feed both purees and fingers foods.
Previous research by Dr Garcia has found a large number of commercial baby food products are high in sugar, and as a result may promote a sweet tooth in infants and encourage snacking on processed food.
The findings were published in the journal Maternal and Child Nutrition.
