New York, June 1, 2017: Stress during pregnancy may cause female children to exhibit binge-eating-like behaviour in adulthood, a study conducted on mice has showed.

Although stressed mothers passed along binge eating-related epigenetic tags on their DNA, the mouse pups’ tendency to binge surfaced only when they too were subjected to stressful situations, the researchers said.

“The price we pay later in life — whether it’s psychiatric disorders, metabolic syndromes, or heart-related illnesses — is heavily impacted by the way your brain was programmed early in life,” said Alon Chen, a neurobiologist at the Weizmann Institute in Israel.

“We have established a model where we can actually show that early life stress increases the likelihood of binge eating in females,” Chen said.

For the study, detailed in the journal Cell Metabolism, the researchers genetically engineered a line of mice, where they manipulated the hormone system that controls cortisol — stress hormones — release to increase the anxiety levels of pregnant mothers during their third trimester.

The mouse pups’ tendency to binge only surfaced when they were placed in a stressful situation where the researchers restricted their access to food.

In addition, measuring the eating habits of stressed mice showed that those born to stressed mothers were more likely to eat large amounts of food during short windows of time.

However, putting the young mice on a diet with “balanced” levels of nutrients such as Vitamin B12 and folate, the researchers were able to prevent their binge eating.

All of this underscores the importance of avoiding stressful situations as much as possible during pregnancy, the researchers added. (IANS)

Researchers have found that spending more time standing up and eating for even a few minutes prompts physical stress, muting taste buds.

The study, published in the Journal of Consumer Research finds posture impacts taste perception, with food tasting better when you are sitting down.

The researchers looked specifically at how the vestibular sense, which is responsible for balance, posture and spatial orientation, interacts with the gustatory sensory system, which impacts taste and flavour.

“This finding suggests that parents might be able to make unpleasant-tasting, healthy foods seem more palatable to reluctant children by having them eat standing up (vs. sitting down). In a similar vein, it might be beneficial to maintain a standing posture when consuming pharmaceutical products that have unpleasant tastes,” said study lead author Dipayan Biswas, Professor at the University of South Florida in the US.

The research team found that the force of gravity pushes blood to the lower parts of the body, causing the heart to work harder to pump blood back up to the top of the body, accelerating heart rate.

This activates the hypothalamic-pituitary adrenal (HPA) axis and leads to increased concentrations of the stress hormone cortisol.

This chain reaction reduces sensory sensitivity, which impacts food and beverage taste evaluation, food temperature perception and overall consumption volume.

When people experience discomfort, foods that normally taste good do not appear as pleasant to the palate, said the study.

The research team confirmed their hypothesis by having 350 participants rate the tastiness of a pita chip. Those who were standing gave it a less favourable rating than those who were sitting in a padded chair.

They expanded the study by inducing additional stress and asked participants to try fruit snacks while carrying a shopping bag. Both sitting and standing participants reported the additional weight made the food item taste even worse. (IANS)
