Just one glass of white wine a day can raise risk of developing skin cancer by 13%

A small glass of white wine a day could increase the risk of skin cancer by 13 per cent, a study suggests.

Drinking alcohol is associated with higher rates of invasive melanoma and white wine carries the greatest risk, according to the research. Those who drank a glass and a half of wine a day increased the risk of developing melanomas on the torso - a rare site of skin cancer - by up to 73 per cent compared with non-drinkers.

Each year, around 2,500 people die from malignant melanoma in the UK. While the link between sun exposure and skin cancer is well known, the fresh findings suggest white wine could lead to cancerous lesions in areas of the body which are less exposed to the sun.

Study author Professor Eunyoung Cho, from Brown University in the US, said: 'It was surprising that white wine was the only drink independently associated with increased risk of melanoma. The reason for the association is unknown. However, research has shown that some wine has somewhat higher levels of pre-existing acetaldehyde than beer or spirits.

Drinking too much water is dangerous

Telling people to 'drink plenty of fluids' when unwell could be dangerous, doctors have warned.

Experts at King's College Hospital in south London questioned the recommendation after treating a 59-year-old woman who drank so much water that she became gravely ill. The woman, who is not named, overdosed on water after developing symptoms of a urinary tract infection.

She recalled being told by a doctor previously to drink lots of water - half a pint every 30 minutes - though she said she thought in this case, she had consumed more to 'flush out her system'.

The woman was admitted to A&E, where doctors found she was suffering from dangerously low levels of salt in her blood. This can occur if too much water is drunk over a short period of time. Symptoms include nausea, vomiting and headaches. In serious cases, the brain can swell, which can lead to confusion, seizures, coma and death.
A death rate of almost 30 per cent has been reported in patients with abnormally low salt levels. Writing in the journal BMJ Case Reports, doctors said there was little evidence to know how much water is too much.

Why are probiotic yoghurts so good for us?

Scientists have finally dissected why probiotic yoghurts are good for our bodies.

We are all hounded by adverts and health alerts telling us probiotic yoghurts or supplements are packed with friendly bacteria that boost the body's defenses. But to date, the science behind that connection has been murky. Now, researchers have managed to shed light inside the black box of probiotics to uncover the mechanism by which these live bacteria confer health benefits to the gut. 


The benefits are down to the communication between the probiotic bacteria and the human host. This involves the bacterial secretion of a novel polysaccharide that tells the immune system to release certain immunity-stimulating chemicals.

The study looked at the bacteria strain Lactobacillus paracasei DG found in the one of Italy's most popular supplements Enterolactis on sale for the past two decades. In the experiments, researchers isolated the polysaccharide, which are large polymers of sugar molecules.
