(Press-News.org) Adding tiny amounts of vegetable puree to milk and then rice at the time of weaning makes children more likely to eat vegetables, new University of Leeds research shows.
Infants who consumed either milk (breast milk or formula) followed by rice mixed with vegetable puree ate nearly half as many vegetables again as infants who ate just milk followed by baby rice.
Professor Marion Hetherington, of the School of Psychology at the University of Leeds, led the study. She said: "We took inspiration from French mothers, as previous studies in this area have shown that they often add vegetable cooking water to their infants' milk to help introduce them to eating vegetables at weaning. For years, French mums have shown that getting their children to eat vegetables early is child's play."
In the project, 36 mothers with babies aged from six months were split into two groups. One group was given plain milk for 12 consecutive days followed by plain rice for 12 consecutive days.
The other group was given milk with added vegetable puree for 12 days followed by rice with vegetable puree for 12 more days.
After this, both groups were given vegetable puree for 11 consecutive days, and this is where the difference in intake was observed.
Vegetables were given in a rotation, with carrots, green beans, spinach and broccoli used. Carrots were by far the most popular vegetable among the infants, being much more readily eaten than green beans, spinach or broccoli.
Professor Hetherington continued: "What this study shows is that by doing a relatively simple thing, like adding vegetable puree to milk and then baby rice, children eat vegetables more readily. Vegetables tend to be bitter, so a gradual introduction is an easy way to let children get used to them.
"Breast milk contains flavours carried from the maternal diet to the infants, so it is important for mums to eat a variety of vegetables and to maintain a healthy diet, too."
The research was published in the journal Appetite and is available online.
Danone Nutricia Research was partner in this EU-funded project and involved in the design of the study, as academia-industry co-operation is a condition of European Union funding for the project.
NHS guidelines advise to start weaning children on to solid foods at around six months. During the study, parents were given the option of either bottle-feeding or spoon-feeding the mixture to their babies.
Professor Hetherington is part of the Human Appetite Research Unit (HARU) at the University of Leeds. Her research in the HARU Lifespan group involves characterising appetite expression from the early years of life to the end of life. In particular the group is interested in the development of food preferences in early life, the expression of hunger and satiety cues in infancy and how mothers respond to these.
Professor Hetherington added: "This was a small sample size, but it is important to note that we are focussing more and more on the first 1000 days of life as evidence is increasing that these are particularly important for later health and the development of healthy eating habits."

Overall, 46% more vegetable puree was eaten by the intervention group compared to the control group. Infants in both groups ate 48% more carrot than green bean puree.
In total, the research team made contact with 48 mothers and from this initial contact 40 mothers were screened and accepted into the study. Four did not complete the study.

(SACRAMENTO, Calif.) -- In its first clinical application in pediatric patients, an investigational medication developed and manufactured at UC Davis has been found to effectively treat children with life-threatening and difficult-to-control epileptic seizures without side effects, according to a research report by scientists at UC Davis and Northwestern University.
The investigational formulation of allopregnanolone was manufactured by UC Davis Health System's Good Manufacturing Practice Laboratory. Two children were treated with the allopregnanolone formulation, one ...
LA JOLLA, CA - November 12, 2014 - Driving to work becomes routine--but could you drive the entire way in reverse gear? Humans, like many animals, are accustomed to seeing objects pass behind us as we go forward. Moving backwards feels unnatural.
In a new study, scientists from The Scripps Research Institute (TSRI) reveal that moving forward actually trains the brain to perceive the world normally. The findings also show that the relationship between neurons in the eye and the brain is more complicated than previously thought--in fact, the order in which we see things ...
(MEMPHIS, Tenn. - November 12, 2014) An international collaboration has identified frequent mutations in two genes that often occur together in Ewing sarcoma (EWS) and that define a subtype of the cancer associated with reduced survival. The research, conducted by the St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project and the Institut Curie-Inserm through the International Cancer Genome Consortium, appears in the current issue of the scientific journal Cancer Discovery.
Mutations in the genes STAG2 and TP53 have previously been ...
Giant otters may have a vocal repertoire with 22 distinct vocalization types produced by adults and 11 neonate vocalization types, according to a study published November 12, 2014 in the open-access journal PLOS ONE by Christina Mumm and Mirjam Knörnschild from University of Ulm, Germany.
Giant otters, found in South America, are very social and frequently vocalizing animals. They live in groups that may vary, but generally include a reproductive pair and their offspring, born in different years. Individuals engage in shared group activities and hold different social ...

An educational approach in kindergarten focused on the development of executive functions--the ability to avoid distractions, focus attention, hold relevant details in working memory, and regulate impulsive behavior--in children improved academic learning in and beyond kindergarten, helping to overcome deficits in school readiness associated with poverty, according to a study published November 12, 2014 in the open-access journal PLOS ONE by Clancy Blair and C. Cybele Raver from New York University.
Based on the results, the authors suggest that executive function ...
An educational approach focused on the development of children's executive functions - the ability to avoid distractions, focus attention, hold relevant information in working memory, and regulate impulsive behavior - improved academic learning in and beyond kindergarten, according to a new study by researchers at NYU's Steinhardt School of Culture, Education, and Human Development.
Because some effects were especially pronounced in high-poverty schools, the findings hold promise for closing the poverty-related achievement gap and suggest that an emphasis on executive ...
The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that for the first time ever, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere.
"The weather on Uranus is incredibly active," said Imke de Pater, professor and chair of astronomy at the University of California, Berkeley, and leader of the team that first noticed the activity when observing the planet with adaptive optics on the W. M. Keck II Telescope in Hawaii.
"This type of activity would have been expected in 2007, when Uranus's ...
In the fight against HIV, microbicides--chemical compounds that can be applied topically to the female genital tract to protect against sexually transmitted infections--have been touted as an effective alternative to condoms. However, while these compounds are successful at preventing transmission of the virus in a petri dish, clinical trials using microbicides have largely failed. A new study from the Gladstone Institutes and the University of Ulm now reveals that this discrepancy may be due to the primary mode of transportation of the virus during sexual transmission, ...
