(Press-News.org) Beware of those snack attacks. A new study in Appetite has confirmed the small luxuries, from sweets and chocolate to salty treats, have helped to lift our spirits - and kilojoule intake - during COVID-19 lockdowns.
Researchers in England and Australia have gathered evidence about similar experiences in the UK and Victoria, Australia to warn about the effect of extended pandemic lockdowns on our eating behaviours.
While time at home provides more time for healthy food preparation, intake of high-energy density foods (HED) has risen for some - presenting at-risk adults with the prospect of managing weight gain, the psychology researchers warn.
"The new stresses created by the pandemic appears to be associated with reported increases in overall savoury and sweet snack intake," says lead researcher Dr Nicola Buckland, who assessed dietary survey responses from 588 people during the first UK lockdown (May-June 2020).
Participants indicated whether their intake of tasty, calorific foods (e.g. chocolate, cake, ice cream, pizza) had changed during the lockdown. These are foods that people typically report to be difficult to resist and difficult to control intake of. Participants also completed questionnaires that measured individual eating styles.
"The findings showed that, in terms of dietary changes, not everyone responded the same way to the lockdown. Over half of the respondents (53%) reported increased snack intake, 26% reported decreased snack intake and 20% reported no changes to the amount of snacks they ate during the lockdown.
"When we looked at the participants' eating styles (based on responses to the questionnaires), we found that participants who scored low in the ability to control cravings were more likely to report increased snack intake."
Flinders University Professor of Psychology Eva Kemps says the first COVID-19 lockdown started in Victoria, Australia just after the UK research was conducted.
The 124 respondents in the Australian survey also reported changes in food intake and eating styles changed during the lockdown, as well as their perceived stress levels.
Similar to the UK findings, of the Australian respondents, 49% reported increased snack intake during the COVID-19 lockdown, and the remaining respondents reported either reduced snack intake (25%) or no change (26%).
"Increased snack intake was associated with higher levels of perceived stress, indicating that those who experienced higher levels of stress reported greater increases of sweet and savoury snack foods," Professor Kemps says.
"Also, similar to the UK survey, participants with low craving control were most likely to report increased snack intake."
The findings from the UK and Australian surveys show that for some people, especially those who have difficulty controlling food cravings, the COVID-19 lockdowns were a risky time period for increased food intake, the researchers say.
"Our findings support the use of strategies that can help people to manage their cravings, to minimise the risk of increased snack intake during the COVID-19 lockdowns."

The response times of footballers is slowed down when part of the kit worn by both teams is of the same colour, a new study shows.
The research from the University of York revealed that when players have any kit colour clash - either shirt or shorts - it takes them twice as long to find a fellow player on the pitch.
Study authors are calling for a change in the laws of the game or for clearer guidance.
Researchers used two experiments to investigate how kit variations affect the visual search for teammates. Their first experiment confirmed that a ...
Profs. Okujima and Uno at Ehime University, in collaboration with Prof. Kobayashi at Shinshu University, reported the selective synthesis, the molecular structure, optical properties and electronic structure of cyclo[9]pyrrole, a ring-expanded porphyrin consisting of directly connected pyrrole rings.
Porphyrins, which are well-known natural porphyrin molecules, e.g. heme and chlorophyll, are attractive for use in practical materials because of the easy optimization of their optical and physical properties by conjugation expansion and functionalization. In 2002, Sessler reported the first synthesis of cyclo[n]pyrrole (n: ...
A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth. The study is published today in Monthly Notices of the Royal Astronomical Society.
The number of confirmed planets in our own Milky Way galaxy now numbers into the thousands. However planets that are both Earth-like and in the habitable zone - the region around a star where the temperature is just right for liquid water to exist on the surface - are much less common.
At the moment, only a handful of such rocky and potentially habitable exoplanets ...
Research Associate Artyom Gusarov studied a vast array of erosion data to make a general takeaway that soil erosion and river sediment load in the aforementioned region has significantly decreased throughout the post-Soviet period.
"The decrease has been especially profound in the forest steppe, a part of which covers the Republic of Tatarstan, because of the combined influence of climate change and land cultivation," explains Gusarov. "To the north of the forest steppe, in the southern part of the boreal zone, the anthropogenic factor was the primary influence on the changes in soil erosion, at least in the east of the East European Plain. ...
As much as 20% of premature mortality can be attributed to poor urban and transport planning. Nevertheless, quantitative indicators to guide the integration of health components into urban design have been lacking. To address this gap, a team from the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has identified 10 principles--and corresponding indicators--to help urban planners incorporate public health into their work.
The new study, published in the International Journal of Hygiene and Environmental Health, was undertaken at the request of the Directorate-General for Environmental Policies and the Natural Environment, which forms ...
Organic solar elements with the self-assembling molecular-thin layer (SAM) of hole-transporting material, the technology, which was used in producing a record-breaking tandem solar cell, achieved 18.4 power conversion efficiency. The invention of Lithuanian chemists working at Kaunas University of Technology (KTU), commercialized by several global companies proved versatile and applicable to different solar technologies.
Organic solar cells are made of common organic elements such as carbon, hydrogen, nitrogen, fluorine, oxygen, and sulphur. Their raw materials are cheap, abundant, and can ...
The Earth is a sphere, and it comprises spheres: atmosphere, hydrosphere, cryosphere, lithosphere and biosphere -- in short, all of the cycles that interact to influence Earth's weather and climate. Now, to better research how the spheres interact and impact the planet, China is launching EarthLab in Beijing. On June 23, after EarthLab's opening ceremony, researchers will begin trials to demonstrate the facility's ability to integrate simulations and observations to more accurately project outcomes and provide a scientific foundation to predict and mitigate such things as natural weather disasters.
EarthLab's ...
A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 years old --more than what was thought to date-- according to an article published in the journal Biological Reviews.
The study analyses for the first time the symbiotic associations and the coevolution between ambrosia fungi and beetles from a paleontological perspective using the Cretaceous ...
Everybody from a child knows that elephants trumpet. Over the past decades research in general and at the University of Vienna has mainly studied the elephants low-frequency rumble. Its fundamental frequency reaches into the infrasonic range below the human hearing threshold. This call is produced by the elephant´s massive vocal folds. Much less was known about how elephants produce their higher pitched sounds, trumpets and squeaks.
The following rule generally applies to sound production in mammals: the larger the vocal fold, the lower the calls fundamental frequency. Conversely the size of the vocal folds sets an upper limit to the fundamental frequencies that can be reached. The high-pitched squeak only Asian but not African elephants ...
University of Maryland researchers created the first high-resolution image of an expanding bubble of hot plasma and ionized gas where stars are born. Previous low-resolution images did not clearly show the bubble or reveal how it expanded into the surrounding gas.
The researchers used data collected by the Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope to analyze one of the brightest, most massive star-forming regions in the Milky Way galaxy. Their analysis showed that a single, expanding bubble of warm gas surrounds the Westerlund 2 star cluster and disproved earlier studies suggesting there may be two bubbles surrounding Westerlund 2. The researchers also identified the source of the bubble ...
