1 Hour Window to Build Healthier Eating Habits

 Millions of working parents know the routine: bustle the kids off to childcare in the morning, work all day, then fight the daily traffic jams to get the kids back home. Something to drink, maybe a snack to munch, can help ease the commute.

Understandably, few parents take the time to think about the nutrients or calories involved, but experts at Cincinnati Children's decided to take a closer look.

Their eyebrow-raising findings were published April 27, 2024, in the journal Children's Health Care.

The researchers took a fresh look at older data contained in daily food journals kept by more than 300 families of children who attended 30 childcare centers that participated in the Preschool Eating and Activity Study (2009-2011). They found that the hour after parents and caregivers picked up their children stood out as a high-calorie, relatively less healthy part of the child's overall diet.

Overall, these children, ages 3 to 5, consumed more than 1,471 calories across the entire day -- an amount on the high end of recommended daily limits.

Of that amount, 290 calories, on average, were consumed in the hour after leaving day care.

That's about 20% of the day's entire calorie intake.

Adding concern: after-care food and drink accounted for about 22% of the day's added sugar and about one-third of the sweet and salty snack foods the children ate.

"Every parent knows how busy that time of day can feel. Parents can feel stressed, the kids may be cranky, hungry, or tired. There's nothing wrong with treats once in a while," says senior author Kristen Copeland, MD, Division of General and Community Pediatrics.

"But that car ride home also can be an opportunity to instill healthier habits instead of less healthy ones."

If busy parents want to try a small change that might make a big difference, consider stocking the car with veggie sticks, cheese, fruit slices, and low-sugar drinks such as water or milk.

A few minutes of preparation can make it easier to skip the high-calorie drive-throughs and sugar-loaded packaged snacks.

"Children of preschool age are in a highly habit-forming time of their lives. They thrive on routine," Copeland says. "Children often look forward to the car ride home, which makes that time an opportunity to start a healthy snacking habit that could last a lifetime."

 A government-funded study on the potential for cross-contaminating kitchen surfaces with pathogens during food preparation has pointed to an unlikely culprit for spreading sickness: spice containers.

 

Detailing findings in the Journal of Food Protection, Donald Schaffner, a Distinguished Professor in the Department of Food Science at the Rutgers School of Environmental and Biological Sciences who co-authored the study in collaboration with North Carolina State University colleagues, concluded that when consumers are preparing meals, spice containers can easily become cross-contaminated with health-threatening microorganisms. Cross-contamination is the process by which microbes are transferred from one substance or object to another, often with harmful effects.

 

The study was commissioned by the U.S. Department of Agriculture's (USDA) Food Safety and Inspection Service.

 

"In addition to more obvious surfaces like cutting boards, garbage can lids and refrigerator handles, here's something else that you need to pay attention to when you're trying to be clean and sanitary in your kitchen," Schaffner said. "Our research shows that any spice container you touch when you're preparing raw meat might get cross-contaminated. You'll want to be conscious of that during or after meal preparation."

 

Foodborne illnesses such as non-typhoidal Salmonella and Campylobacter account for nearly 2 million infections per year in the U.S., according to studies by the U.S. Centers for Disease Control and Prevention (CDC). A significant portion of those illnesses are derived from USDA-regulated food products, including chicken, turkey, beef, pork and game, according to the Interagency Food Safety Analytics Collaboration, a group formed in 2011 by the CDC, the USDA's Food Safety and Inspection Service and the U.S. Food and Drug Administration. Scientists said they believe proper handling of food -- including adequate cooking, consistent handwashing and sanitizing of kitchen surfaces and utensils -- can combat cross-contamination.

 

"The purpose of this study was to determine the prevalence and degree of cross-contamination across a variety of kitchen surfaces during a consumer meal preparation event," said Schaffner, who also is the Rutgers Agricultural Experiment Station's Extension Specialist in Food Science.

 

Researchers monitored the behavior of 371 adults cooking an identical turkey burger recipe in several kitchens of various sizes, ranging from small apartment-style kitchens to larger teaching kitchens, in extension centers and food banks. Participants prepared a meal consisting of raw ground turkey patties with a seasoning recipe, along with a prepackaged salad. To simulate the movement of a pathogen across a kitchen, researchers inoculated the meat ahead of time with a bacteriophage known as "MS2" to serve as a safe tracer. Bacteriophages are viruses that infect bacteria and have no effect on humans.

 

Participants weren't informed that researchers would be examining their food safety behaviors until after they had prepared the meal. Once the meal had been prepared, researchers swabbed kitchen utensils, cleaning areas and kitchen surfaces to test for the presence of the MS2 tracer. Based on observations of participants' behavior during cooking, researchers decided to take samples from some new categories of surfaces, such as spice containers and sink faucet handles.

 

The researchers found the most frequently contaminated objects were spice containers, with about 48 percent of the samples showing evidence of MS2 contamination. This prevalence of contamination was significantly different from many other surfaces sampled. Cutting boards and trash can lids were the second and third most contaminated. Faucet handles were the least contaminated object studied.

 

"We were surprised because we had not seen evidence of spice container contamination before," Schaffner said. "Most research on the cross-contamination of kitchen surfaces due to handling of raw meat or poultry products has focused on kitchen cutting boards or faucet handles and has neglected surfaces like spice containers, trash bin lids and other kitchen utensils. This makes this study and similar studies from members of this group more comprehensive than previous studies."

 

Researchers involved included Benjamin Chapman, professor and department head, Agricultural and Human Sciences, and Lee-Ann Jaykus, the William Neal Reynolds Distinguished Professor, Food, Bioprocessing and Nutrition Sciences, Margaret Kirchner, Savana Everhart, Lindsey Doring, Caitlin Smits, Jeremy Faircloth, Minh Duong, Rebecca Goulter, Lydia Goodson, Lisa Shelley and Ellen Thomas Shumaker, all of North Carolina State University; Sheryl Cates of RTI International; Christopher Bernstein of the Consumer Financial Protection Bureau; and Aaron Lavallee of the U.S. De

Plant-based alternative food consumption may have doubled in UK over ten years suggests first analysis of its kind

The proportion of UK people reporting eating and drinking plant-based alternative foods such as plant-based milk, vegan sausages and vegetable burgers nearly doubled between 2008-2011 and 2017-2019, according to a new study in Science of the Total Environment.

The study was led by the London School of Hygiene & Tropical Medicine (LSHTM), with partners the University of Oxford. It is believed to be the first analysis of plant-based alternative foods (PBAF) consumption trends in the UK.

Trends from more than 15,000 individuals aged 1.5 years and over were analysed using consumption data from the National Diet and Nutrition Survey 2008-20191. The team found that the proportion of people that reported to eat and drink plant-based alternative foods nearly doubled over the period of the study from 6.7% to 13.1%.

The largest increases were reported among Generation Y (11-23 years old), Millennials (24-39 years old), and among those that reported low meat consumption. Women were also 46% more likely to report consumption of plant-based alternative foods than men.

The researchers say their study suggests that alternative plant-based foods are likely to play an important role in dietary change away from meat and dairy, and take a considerable place in UK diets. However, it remains unknown how healthy and sustainable these alternatives are, so the team call for urgent research to see if the shift to these foods should be strategically promoted.

Dr Pauline Scheelbeek from LSHTM and study author, said: "A global transformation towards sustainable food systems is crucial for delivering on climate change mitigation targets worldwide. In high- and middle-income settings, plant-based meat and dairy alternatives are increasingly being explored and developed as a strategy to reduce consumption of animal-sourced foods. However, the extent to which these foods play a role in dietary change remains largely understudied. This study helps fill that gap."

Evidence suggests current global food systems and patterns of consumption are unsustainable for human and planetary health. The food system is responsible for roughly 21-37% of global greenhouse gas (GHG) emissions and agriculture accounts for around 70% of freshwater use globally.

To meet the targets set out in the Paris agreements a global transition to sustainable diets is crucial and being widely promoted. Research has demonstrated that in high- and middle-income settings (with diets that are typically high in animal-sourced foods) substituting animal products with plant-based sources of food can substantially reduce impacts on the environment and improve population health.

As part of its recommendations for achieving a reduction in emissions, the UK Climate Change Committee (UKCCC) has suggested a 20% reduction in high?carbon meat and dairy products by 2030, rising to a 35% reduction by 2050, with increased consumption of plant-based products.

However, social facilitation, pleasure, and beliefs about the importance of meat in the diet are barriers for many to change diets. PBAF present a potential solution as they are designed to mimic the taste and texture of their animal-based counterparts and limit changes in meal habits and cooking skills.

Dr Scheelbeek said: "The willingness to reduce meat intake among populations in many European countries has increased rapidly over the past decade. Unfortunately, this does not always result into actual dietary change. The plant-based alternative foods could be a stepping stone for people that are willing to reduce meat consumption, but find it hard to fit this into their daily lives. This study shows that more and more people are applying this pathway to achieve their goals on more plant-based diets."

In this new study, the team examined plant-based PBAF consumption trends in the UK by analysing national representative consumption data from the National Diet and Nutrition Survey for the years 2008-2019. They found that from all plant-based alternative foods, plant-based milks were most popular among the UK population with approximately 1 in 13 people (7.4%) reporting to consume plant-based milks in 2018 and 2019 as compared to 2.3% in 2008-2011.

The consumption of plant-based alternatives for other dairy products -- such as vegan cheese and yoghurt -- showed to be taking off at a slower pace, with only 1.2% of the respondents reporting to consume such products in 2018 and 2019.

As well as overall trends at population level, the researchers looked at age, socioeconomic and geographical sub-groups. Consumption of plant-based alternative foods were substantially higher among those with higher incomes, suggesting potential inequalities in affordability of the plant-based alternative foods across societal groups. Women were more likely to report plant-based alternative food consumption than men, and younger generations (13-39 years of age) more than older generations.

Evidence that plant-based alternative foods are used as a direct replacement for meat and dairy was further strengthened due to the fact that those reporting low meat consumption consumed -- on average -- triple the amount of plant-based alternative foods as compared to high meat eaters.

Professor Alan Dangour from LSHTM and a study author, said: "We are seeing a revolution in consumer patterns that could have dramatic impacts on our food systems. Our study shows just how quickly diets are changing in the UK and how willing the UK public are to adopt new foods. We must now ensure that as we transition to diets with more novel foods, the diets enhance public health and have a substantially lower impact on our planet."

The authors acknowledge limitations of their study, including that while food diaries offer an advantage of accuracy over recall dietary assessment methods, underreporting can occur. Data analysis limitations also resulted in exclusion of many food items such as desserts, baked goods and snacks; therefore, consumption of some food groups, particularly dairy products and milk, is under-estimated.

Supportive strategies help 'picky eaters' deal with food aversions

In a large national survey, adults who struggled with picky eating habits as children overwhelmingly said they benefitted more from positive and encouraging strategies their parents used than forceful or coercive approaches.

The research, led by a team at Duke Health, was conducted among a generation of people who struggled with food avoidance before it was identified in 2013 as a psychiatric condition called Avoidant/Restrictive Food Intake Disorder (ARFID).

The researchers said their findings, appearing online Nov. 11 in the International Journal of Eating Disorders, provide guidance for both families and behavioral health professionals for developing best practices to deal with extreme food aversions.

When picky eating is severe, it is diagnosed as ARFID. The condition is characterized by health problems such as weight loss and nutritional deficiencies and it can also lead to social and emotional problems when mealtimes become a source of shame, friction and/or conflict.

"It's not surprising that positive approaches were favored, but it is surprising how overwhelming that position was among this group of adults," said Nancy Zucker, Ph.D., professor in the Duke's Department of Psychiatry & Behavioral Sciences. Zucker was co-senior author on the study with Guillermo Sapiro, Ph.D., professor of electrical and computer engineering at Duke's Pratt School of Engineering.

Zucker, director of the Duke Center for Eating Disorders, said the broad consensus is validation for the current treatment approach that emphasizes positive interactions: "It is robust confirmation for what had been out there in the literature and reinforces the concept that children feeling forced or pressured to eat is not helpful."

The study was launched more than a decade ago as severe food avoidance was gaining attention and research into the disorder was limited. The online survey was aimed at adults who self-identified as current picky eaters to help understand their perceptions and experiences.

More than 19,200 people were included in the survey; 75% were female and 25% were male, and 89% were white. Respondents were asked to describe food presentation strategies used by their parents or caregivers that they found to be helpful or not helpful in increasing food variety.

Survey participants were subsequently classified as either likely having an ARFID diagnosis or not, based on their degree of impairment from food avoidance. Those who reported that eating problems led to significant weight loss, nutritional deficiency, interference with job functioning and/or interference with social relationships were categorized as likely having ARFID.

Interpreting the narrative responses from the huge cohort of participants created a logistical challenge, which was solved with the application of sophisticated artificial intelligence tools.

Using a computational tool to characterize the perceived helpfulness of parent feeding strategies, the researchers applied an algorithm to interpret the meaning and/or sentiment of survey responses to characterize them as helpful or not helpful.

"From a technical perspective, this study used an AI application that understands language, not just words and sentences, but concepts of paragraphs, which was imperative here," said J. Matías Di Martino, Ph.D., co-lead author with doctoral student Young Kyung Kim. Both are in Duke's Department of Electrical and Computer Engineering. "By getting the positive and negative emotions, it enables us to analyze the comprehensive memories of nearly 20,000 people."

The researchers found that 39% of the themes regarding helpful strategies mention a positive emotional context, such as using food to teach cultural or nutritional lessons, being flexible about the approach to food, providing plenty of safe foods, helping with food preparation, or presenting foods from specific food groups.

Forty percent of the helpful comments noted the importance of structure around eating. Clearly defined expectations around eating were deemed to be helpful in the context of distinguishing between feeling "forced" vs. being asked to do something.

While positive and encouraging strategies were perceived as helpful in improving attitudes towards food and minimizing social discomfort around eating, many adults still struggled with a degree of avoidance/restriction. The researchers noted that parents are perceived as having a positive impact despite their children's food avoidance persisting into adulthood.

The researchers said survey participants clearly found some foods aversive, not merely unpleasant. This likely intensified their feeling of being trapped and made to do something disgusting if they were asked to eat that food.

"To our knowledge, there is no published research that identifies effective feeding strategies for those with ARFID," Zucker said. "Figuring out the best way to feed a child with severe food avoidance can be exhausting and stressful for parents, so providing guidance is essential to improve the social and emotional eating environment for their children and reduce the distress that both parents and children have at mealtimes."

In addition to Zucker, Sapiro, Di Martino and Kim, study authors include Julia Nicholas, Alannah Rivera-Cancel, Jennifer E. Wildes and Marsha D. Marcus.

The study received support from the National Institutes of Health (R01MH122370).

Children who eat a better diet, packed with fruit and vegetables, have better mental wellbeing

A new study published today is the first to investigate the association between fruit and vegetable intakes, breakfast and lunch choices, and mental wellbeing in UK school children.

It shows how eating more fruit and veg is linked with better wellbeing among secondary school pupils in particular. And children who consumed five or more portions of fruit and veg a day had the highest scores for mental wellbeing.

The study was led by UEA Health and Social Care Partners in collaboration with Norfolk County Council.

The research team say that public health strategies and school policies should be developed to ensure that good quality nutrition is available to all children before and during school to optimise mental wellbeing and empower children to fulfil their full potential.

Lead researcher Prof Ailsa Welch, from UEA's Norwich Medical School, said: "We know that poor mental wellbeing is a major issue for young people and is likely to have long-term negative consequences.

"The pressures of social media and modern school culture have been touted as potential reasons for a rising prevalence of low mental wellbeing in children and young people.

"And there is a growing recognition of the importance of mental health and wellbeing in early life -- not least because adolescent mental health problems often persist into adulthood, leading to poorer life outcomes and achievement.

"While the links between nutrition and physical health are well understood, until now, not much has been known about whether nutrition plays a part in children's emotional wellbeing. So, we set out to investigate the association between dietary choices and mental wellbeing among schoolchildren."

The research team studied data from almost 9,000 children in 50 schools across Norfolk (7,570 secondary and 1,253 primary school children) taken from the Norfolk children and Young People's Health and wellbeing Survey.

This survey was commissioned by the Public Health department of Norfolk County Council and the Norfolk Safeguarding Children Board. It was open to all Norfolk schools during October 2017.

Children involved in the study self-reported their dietary choices and took part in age-appropriate tests of mental wellbeing that covered cheerfulness, relaxation, and having good interpersonal relationships.

Prof Welch said: "In terms of nutrition, we found that only around a quarter of secondary-school children and 28 per cent of primary-school children reported eating the recommended five-a-day fruits and vegetables. And just under one in ten children were not eating any fruits or vegetables.

"More than one in five secondary school children and one in 10 primary children didn't eat breakfast. And more than one in 10 secondary school children didn't eat lunch.

The team looked at the association between nutritional factors and mental wellbeing and took into account other factors that might have an impact -- such as adverse childhood experiences and home situations.

Dr Richard Hayhoe, also from UEA's Norwich Medical School, said: "We found that eating well was associated with better mental wellbeing in children. And that among secondary school children in particular, there was a really strong link between eating a nutritious diet, packed with fruit and vegetables, and having better mental wellbeing.

"We also found that the types of breakfast and lunch eaten by both primary and secondary school pupils were also significantly associated with wellbeing.

"Children who ate a traditional breakfast experienced better wellbeing than those who only had a snack or drink. But secondary school children who drank energy drinks for breakfast had particularly low mental wellbeing scores, even lower than for those children consuming no breakfast at all.

"According to our data, in a class of 30 secondary school pupils, around 21 will have consumed a conventional-type breakfast, and at least four will have had nothing to eat or drink before starting classes in the morning.

"Similarly, at least three pupils will go into afternoon classes without eating any lunch. This is of concern, and likely to affect not only academic performance at school but also physical growth and development.

"Another interesting thing that we found was that nutrition had as much or more of an impact on wellbeing as factors such as witnessing regular arguing or violence at home.

Prof Welch said: "As a potentially modifiable factor at an individual and societal level, nutrition represents an important public health target for strategies to address childhood mental wellbeing.

"Public health strategies and school policies should be developed to ensure that good quality nutrition is available to all children both before and during school in order to optimise mental wellbeing and empower children to fulfil their full potential.
