Islamabad - A new study has suggested that drinking one glass of milk everyday could not only boost your intake of much-needed key nutrients, but it could also positively impact your brain and mental performance, experts suggest.

The study on which the story is based found that adults with higher intakes of milk and other dairy products did better in memory and other brain function tests than those who drank little or no milk.

The Researchers at the University of Maine conducted a series of brain tests” including visual-spatial, verbal and working memory tests” and tracked the milk consumption habits of the participants.

The results of the study revealed that milk could be good for your bones but so far there is no good evidence that it improves mental performance.

Milk has long been known to help build healthy bones and provide the body with a vitamin and protein boost. But now it’s being hailed as a memory aid after a study found those who regularly have milk – and other dairy products such as yoghurt, cheese and even ice cream – do better in key tests to check their brainpower.

Scientists asked 972 men and women to fill in detailed surveys on their diets, including how often they consumed dairy products, even if only having milk in their tea and coffee.

The subjects, aged 23 to 98, then completed a series of eight rigorous tests to check their concentration, memory and learning abilities.

The study showed adults who consumed dairy products at least five or six times a week did far better in memory tests compared with those who rarely ate or drank them. The researchers said: ‘New and emerging brain health benefits are just one more reason to start each day with low-fat or fat-free milk.’

In some of the tests, adults who rarely consumed dairy products were five times more likely to fail compared with those who had them between two and four times a week. The researchers, from the University of Maine in the U.S., believe certain nutrients in dairy products, such as magnesium, could help to stave off memory loss.

They also suspect dairy foods may help protect against heart disease and high blood pressure, which in turn maintains the brain’s ability to properly function.

Some experts have disputed this, however, claiming dairy products increase the likelihood of heart disease and strokes as they are high in saturated fat.

Coffee intake depends on gene

variation: Study

Researchers suggest people with a DNA variation in the gene PDSS2 drink fewer cups of coffee than those without this variation. Study co-author Dr Nicola Pirastu, from the Usher Institute at the University of Edinburgh in the United Kingdom, and colleagues worked on this study.

The team found that coffee consumption was lower for subjects who had a DNA variation in the PDSS2 gene; they drank an average of one less cup of coffee daily, compared with those who did not have the PDSS2 DNA variation.

The researchers were able to replicate their findings, though they note that the effect of this gene variant on reduction of coffee consumption was not as strong.

The team speculates that this might be due to differences in coffee drinking styles between the two populations; people from Italy tend to consume smaller cups of coffee, such as espresso, while individuals from the Netherlands are more likely to drink larger cups of coffee that contain more caffeine.

Explaining the possible mechanisms behind their findings, the researchers suggest that the DNA variation in the PDSS2 gene lowers cells’ ability to break down caffeine following coffee consumption, prolonging the amount of time the stimulant remains in the body.

As a result, individuals with this genetic variant do not need to drink as much coffee in order to get the same caffeine hit as those without the variant.

Six hidden signs of stress

This may mean that you are stressed. Here are a few signs that are trying to tell you that are stressed. It occurs when people ask you how did you hurt yourself and you do not remember exactly why the cut actually appeared on your skin. Studied show that stress lessens the body’s ability to heal itself.

You are stresses if even a 20 minute nap makes you dream the crazy or dramatic ones. Research shows that to enter REM sleep, it requires 90 minutes and then you start dreaming. The length of your short nap should be 20-30 minutes, because once you enter REM, the nap would leave you cranky after waking up.

When you suffer from dementia at 30 it means you are focusing so much on the mental challenges at hand that everything else seems irrelevant. Excess stress can lose the ability to form, and store new memories not related to the present situation and can make it difficult to retrieve the memories we have.

This happens when a person is so exhausted that their levels of calm bringing neurotransmitters are high. These neurotransmitters override the caffeine’s effects.

Though stress does not induce acid reflux but it can intensify it. A research suggested that when patients diagnosed with acid regurgitation had to perform an anxiety-inducing task, their perception of pain was much higher than fellow acid reflux sufferers who hadn’t been stressed.

If your scalp is itchy even after you had had a hair wash don’t rush to your dermatologist. Rather think introspectively and check what is causing the stress. When you are stressed, you release neuropeptides and other natural chemicals in the skin, and that causes inflammation.
