A recent study led by researchers from University College London (UCL) has revealed that nearly half of toddlers' calorie intake in the UK comes from ultra-processed foods (UPFs), and this number increases significantly by the time they reach seven years old. The study, published in the European Journal of Nutrition, analyzed the diets of 2,591 children born between 2007 and 2008, with parents documenting their children's food consumption over a three-day period. The findings highlight the increasing dependence on UPFs from an early age, raising concerns about long-term health implications.
The study categorized food into four groups using the Nova classification: unprocessed or minimally processed foods like milk, vegetables, and eggs; processed culinary ingredients like butter, salt, and oil; processed foods such as cheese, peanut butter, and tinned fish; and ultra-processed foods. UPFs, often industrially manufactured, contain ingredients not commonly found in home cooking, such as preservatives, emulsifiers, and sweeteners. Common examples of UPFs include cereals, flavored yoghurts, biscuits, sausages, and crisps.
The research showed that at 21 months, toddlers in the study consumed 47% of their calories from UPFs. Foods often viewed as healthy, such as wholegrain breakfast cereals and flavored yoghurts, were frequently consumed by the children, contributing to their overall UPF intake. However, these foods often contain significant amounts of added sugar and salt, leading to concerns about their suitability for young children. By the time these children reached seven years old, their UPF intake rose to 59%, with sweet cereals, white bread, and puddings being the most commonly consumed ultra-processed items.

The lead author of the study, Dr. Rana Conway from UCL's Institute of Epidemiology & Health Care, acknowledged that not all UPFs are inherently harmful. Many foods perceived as healthy fall into this category. However, she noted that the added sugar and salt in some products, such as flavored yoghurts and wholegrain cereals, pose health risks, particularly for toddlers. She emphasized that children who consume higher amounts of UPFs tend to have a greater intake of sugar and salt, which exceeds the recommended daily limits for children in this age group.
Another critical finding of the study was the long-term impact of early dietary habits on future food choices. Professor Clare Llewellyn, a senior author of the study, explained that eating patterns established in the early years of life often persist into later childhood and adulthood. For example, toddlers who consumed a large proportion of UPFs at 21 months were far more likely to continue this pattern by the age of seven. The research found that toddlers with the highest UPF consumption were nearly 9.4 times more likely to continue consuming high amounts of ultra-processed foods as they grew older.
Eating patterns in the early years are important, as they help set habits that can persist through childhood and into adulthood.

This continuity in dietary habits may be partly due to the "hyperpalatable" nature of UPFs. These foods, which are high in fat, sugar, and salt, tend to be more appealing, making it difficult for children to transition to a healthier diet. The researchers stressed that frequent consumption of UPFs could reduce children's exposure to the natural flavors of whole foods, making it harder to establish healthier eating patterns later in life.
One of the study's more alarming findings was that in all five UPF groups, toddlers' intake of free sugars exceeded the UK government's recommendation of a maximum of 5% of daily calories. In the two highest UPF-consuming groups, sugar intake accounted for more than 10% of daily calories on average. This overconsumption of sugar at such an early age has raised concerns about the risk of developing long-term health issues such as obesity, type 2 diabetes, and dental problems.
The study also highlighted socioeconomic factors that may influence the high consumption of UPFs. Dr. Conway pointed out that highly processed foods are often more affordable than fresh, minimally processed alternatives, making it difficult for parents to prioritize healthier choices. Many UPFs marketed toward children are labeled as healthy but contain significant amounts of added sugar and salt. This deceptive marketing, coupled with the higher price of fresh produce, complicates efforts to improve children's diets.
The research team also acknowledged the limitations of their study, noting that the population sample was overrepresented by individuals of white ethnicity and higher socioeconomic status compared to the general UK population. While this does not negate the findings, it suggests that further research may be needed to assess how UPF consumption varies across different demographic groups.
To mitigate the impact of UPFs on children's health, the researchers proposed several policy measures. These included restricting the promotion of unhealthy, ultra-processed foods aimed at children, adding warning labels to products high in sugar, and subsidizing fresh, minimally processed foods to make them more accessible to families. The team also highlighted the potential for marketing healthier alternatives that mimic UPFs in texture and taste but do not contain harmful additives.
Early exposure to healthier options could encourage children to develop a taste for natural, unprocessed foods. However, the researchers cautioned that even products designed to resemble UPFs, such as vegetable sticks or puffs, may not encourage long-term vegetable consumption if children do not experience the flavors and textures of real vegetables.
In conclusion, the UCL-led study sheds light on the concerning rise in ultra-processed food consumption among young children in the UK. While not all UPFs are detrimental, the high levels of added sugar and salt in many of these foods, coupled with their affordability and marketing appeal, create significant challenges for parents trying to promote healthier diets. Addressing these issues through targeted policies and increased access to fresh foods could help shift children's diets toward healthier, more natural alternatives in the future.
