High-Fibre Diets Are Good For Stress, According To Scientists

The research provides new insights into mechanisms related to the impact of the gut bacteria on the brain and behaviour as well as gut health

If you want to reduce your stress then you should eat more pulses, wholegrain cereals, oats and vegetables as consumption of high-fibre foods may help reduce the effect of stress, says a study.

The authors explained that stress can cause major changes in the gut and also in our brain which in turn affects our behaviour.

Foods rich in fibre was found to reduce this adverse effects of stress in mice.

The findings suggested that a gut bacteria produces short-chain fatty acids (SCFAs), which are the main source of nutrition for cells in this region of the body and high levels of fibres stimulate the production of these SCFAs

“There is a growing recognition of the role of gut bacteria and the chemicals they make in the regulation of physiology and behaviour. The role of short-chain fatty acids in this process is poorly understood up until now,” said corresponding author John F. Cryan from University College Cork in Ireland.

“It will be crucial that we look at whether short-chain fatty acids can ameliorate symptoms of stress-related disorders in humans,” Cryan added.

For the study, published in The Journal of Physiology, the team fed normally produced SCFAs to the mice and then subjected them to stress. They were assessed for anxiety and depressive like behaviour, stress responsiveness, cognition and sociability as well as how easily material passes through the gut.

The results showed that increase levels of SCFAs reduced the levels of stress and anxiety-like behaviour among the mice.

The investigators also explained that stress experienced over a prolonged period of time can affect the bowel by making the barrier between the inside of the gut and the rest of the body less effective and “leaky”.

Treating the condition using the SCFAs can also reverse the “leaky” walls inside the gut, said the study.

The research provides new insights into mechanisms related to the impact of the gut bacteria on the brain and behaviour as well as gut health.

“Developing dietary treatments which target these bacteria will be important for treating stress-related disorders,” said the researchers. (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)
