Could YOGURT treat depression?

Yogurt could help combat depression as a new study reveals so-called 'good bacteria' ease symptoms of the mental health disorder.

Some 64 per cent of adults with irritable bowel syndrome (IBS) and symptoms of depression saw their mental health improve within just six weeks of taking a daily 'good bacteria', or probiotic, supplement, the study revealed.

This is compared to just 32 per cent of patients noting an improvement after taking a placebo.

MRI scanning revealed probiotic-receiving patients experienced changes in the areas of their brains associated with mood.

Preliminary: BRCA variations may work alongside COMT variation to reduce breast cancer

Research looking at genomic data from women with a genetic risk for breast cancer, who may never develop cancer, found their cancer-free state may be related to a second genetic variation. Researchers found through looking at data of women with BRCA 1/2 genetic mutations, that some women also have the co-occurrence of a rare COMT genetic variant. According to Science daily

The data set looked at women who volunteered for non-cancer related clinical trials, leading researchers to believe they have not developed cancer or have a family history of cancer.

Where body fat is carried can predict cancer risk

Scientists have found that carrying fat around your middle could be as good an indicator of cancer risk as body mass index (BMI), according to research.

It shows that adding about 11cm to the waistline increased the risk of obesity related cancers by 13 per cent.

For bowel cancer, adding around 8 cm to the hips is linked to an increased risk of 15 per cent.

Carrying excess body fat can change the levels of sex hormones, such as oestrogen and testosterone, can cause levels of insulin to rise, and lead to inflammation, all of which are factors that have been associated with increased cancer risk.

Is air pollution keeping us awake?

Everyone occasionally struggles to get a good night’s sleep - perhaps being kept awake worries about work, or simply struggling to ‘switch off, according to Daily Mail.

But not many of us will have put our nocturnal worries down to air pollution.

However, a group of researchers now believe that the level of exposure with receive to harmful particles in the air we breathe may be linked to keeping us awake at night.

A study, measured how long participants spent asleep in bed each night and found that levels of sleep efficiency could be down to the impact of air pollution on the body.

'Fat but fit is a big fat myth'

The idea that people can be fat but medically fit is a myth, say experts. According to BBC

They say people who were obese but who had no initial signs of heart disease, diabetes or high cholesterol were not protected from ill health in later life, contradicting previous research.

The term "fat but fit" refers to the alluring theory that if people are obese but all their other metabolic factors such as blood pressure and blood sugar are within recommended limits then the extra weight will not be harmful.

In this study, researchers analysed data of millions patients between 1995 and 2015 to see if this claim held true.
