Gene test that could predict breast cancer years before it strikes
Their study shows the risk can double in women whose genes have been changed by exposure to environmental factors such as hormones, radiation, alcohol, smoking and pollution.
The findings could lead to a blood test that will identify those most at risk of breast cancer and other forms of the disease, the researchers say.
The researchers investigated whether the alteration of a single gene by a process called methylation can predict whether women are at more risk of breast cancer.
Garlic is 100 times more powerful than two popular antibiotics
The compound, diallyl sulphide, is able to pierce a protective 'biofilm' employed by the food bug that makes it hard to destroy.
Tests showed diallyl sulphide was as effective as 100 times bigger doses of the antibiotics erythromycin and ciprofloxacin.
It was also able to work in a fraction of the time taken by the drugs.
The discovery is said to open the door to new treatments for raw and processed meats, and food preparation surfaces.
'This is the first step in developing or thinking about new intervention strategies,' said researcher Dr Michael Konkel, from Washington State University in the US, who has been investigating Campylobacter for 25 years.
'Campylobacter is simply the most common bacterial cause of food-borne illness in the United States and probably the world.'
Symptoms of Campylobacter infection include diarrhoea, cramping, abdominal pain and fever.
The bacteria also trigger nearly a third of cases of a rare paralysing disorder called Guillain-Barre syndrome.
Most Campylobacter infections stem from eating raw or undercooked poultry or foods that have been cross-contaminated via dirty surfaces and utensils.
The research is published in the Journal of Antimicrobial Chemotherapy.
This makes the bugs 1,000 times more resistant to antibiotics than free-floating bacterial cells.
The compound easily penetrated the protective film to kill the microbes by targeting a metabolic enzyme.

Why should we eat five a day and will an apple keep the doctor away? A food writer explores the science behind it..
Is meat good or bad for us? Why is five a day recommended for fruit and vegetables? And can diet really cause cancer – or prevent it?
As a food writer, I am often asked these questions, and in an effort to answer them I have looked at the latest scientific research, hopefully exposing some of the myths and providing a practical guide to the things we eat.
ARE APPLES REALLY THAT GOOD FOR ME?
The phrase ‘an apple a day keeps the doctor away’ was originally a marketing slogan dreamt up by American apple growers at the start of the 20th Century. Their fruit had been made into cider, but after the drink was banned during Prohibition they tried to promote apples as being good to eat instead. So how true is that old adage?Apples have taken a bashing lately for being full of sugar, which dentists warn causes tooth decay, but advising against them is like throwing the baby out with the bathwater. Apples are a good source of fibre. There are two types – the first is insoluble, also referred to as roughage, which increases the bulk of stools, and in turn stimulates gut contractions and keeps the bowels moving regularly.
The Department of Health recommends that adults consume 18g of fibre per day, and a medium apple provides about 3g – similar to a bowl of brown rice. Several studies into the cholesterol-lowering properties of apples recommend eating two a day to get a beneficial dose.
By hitting the daily recommended fibre intake, we may be lowering our risk of colorectal cancer. While diets containing more than 80g of meat per day have been linked to a higher incidence of these tumours, a fibre-rich diet seems to cancel out this effect. The peel, which contains insoluble fibre, has the highest concentration of disease-fighting flavonoids and polyphenols, although this research is based on concentrated extracts rather than the whole fruit.
As for vitamins, variety matters. A single old-fashioned Ribston Pippin has more Vitamin C than a whole pound of Golden Delicious.
You can drink some of the goodness in an apple as well as eating it. Juicing doesn’t alter the vitamin content dramatically, although you do lose a lot of the fibre. Cider vinegar has long been used as a folk-medicine tonic. Science has shown that it can lower blood-sugar levels and that it helps with weight loss, probably by suppressing appetite.
A 2009 Japanese study showed drinking a 500ml drink with a tablespoonful or half-tablespoon of cider vinegar led to greater weight loss, because people ate less, and lower blood cholesterol than drinking water. Mix a splash with honey and oil to make a healthy salad dressing.
WHAT IS THE BEST BREAKFAST?
Sugary breakfast cereals have a high glycaemic index (GI) score – a measure of the effects of carbohydrates in food on blood-sugar levels. It estimates how much each gram of digestible carbohydrate in a food raises blood glucose following consumption, relative to consumption of glucose. GI scores are calculated in relation to glucose, which has the highest score of 100.
The higher a GI reading, the faster the food is digested and the quicker we are hungry again. Conversely, the lower the GI, the longer we feel full and the fewer calories we consume.
This is the reason why a low GI diet is associated with healthy weight, and a lower risk of type 2 diabetes and heart disease, according to the University of Sydney’s International GI Group.
Cornflakes, which are some of the least sugary cereals, have a GI score of more than 80, which is similar to white bread. Low-GI breakfast foods include muesli (avoid added-sugar varieties) and porridge.
‘Go to work on an egg’ – another old marketing phrase – is good advice. Eggs contain protein which makes you feel fuller for longer. A poached egg on wholegrain toast is a great choice.
A full English fried breakfast contains protein and fat as well as carbohydrate – and will keep you full for a long time. However, the calories can be alarmingly high, so a regular fried breakfast will only make you put on weight. As for bread, sourdough has a higher acidity than others due to the addition of lactbacillus, which produces lactic acid, giving it a distinctive tangy taste. There is ongoing research into how this element aids absorption of nutrients such as calcium, zinc and iron better than standard bread.
A glass of freshly squeezed juice is a refreshing shot of vitamins. The British Dietetic Association recommends a small (150ml) glass. Best of all, have the fruit whole or eat some chopped up with live natural yogurt.
CAN I EAT TO AVOID HEART DISEASE AND CANCER?
No one food will kill or cure. But the good news is that a balanced, varied diet has room for fats and carbs – just choose the right kind in the right amounts. Fats help build our cells and are part of good health, but they are high in calories. Eating too many calories can lead to you becoming overweight, which raises risks of heart disease and cancer. Butter has been demonised in the past, but like other fats it delivers and contains fat-soluble vitamins such as A, D and E.The World Cancer Research Fund recommends having no more than 500g of cooked red meat in a week due to the risk of colon cancer. A slice of roast beef is 45g, a thick piece of lamb 90g and a small steak is 100g.
Moderate wine-drinking is championed by Professor Roger Corder, at Barts and the London School of Medicine. In his book The Wine Diet, he recommends traditionally made red wines, which are high in polyphenols, especially one type, procyanadins. These seem to be particularly good for cardiovascular health by protecting against the damage to your blood vessels that causes disease. Such wines range from those from Madiran in south-west France (look for the Tannat grape) to the Douro in Portugal.
The word ‘superfood’ refers to those that are rich in phytochemicals, the micronutrients in food other than vitamins and minerals that protect your body against disease. Tomatoes, onions, garlic, cabbage and green tea are also rich in these compounds and are affordable.
HOW SHOULD I EAT MY FIVE A DAY?
A 2011 study in the European Heart Journal showed that people who ate eight a day were 22 per cent less at risk of dying of heart disease than those who ate three a day.
It’s good to eat vegetables in abundance because they are very high in micronutrients and have less sugar than fruit. Eat as many different kinds as possible and try to ‘eat a rainbow’, as the pigments are linked to different phytochemicals.
A number of micronutrients, including Vitamin C, are best consumed raw or steamed, rather than boiled, in order to not destroy the more fragile types and lose water-soluble vitamins in cooking water.
But fat-soluble vitamins such as A, D, E and K can be more useful when cooked in a little fat. The antioxidant lypocene in tomatoes is better absorbed this way.

No proof bad gums cause heart trouble, experts say
Preventing heart disease is not as easy as brushing your teeth.
While numerous studies have linked gum disease with an increased risk of heart disease and stroke, there is no proof that bad gums actually cause heart disease or strokes, an American Heart Association committee said after reviewing 500 journal articles and studies.
Moreover, claims that dental treatment may prevent heart attack or stroke are unwarranted, the committee of doctors, dentists and infectious-disease researchers said in a statement.
New treatment for prostate cancer gives 'perfect results' for nine in ten men: research
A new treatment for prostate cancer can rid the disease from nine in ten men without debilitating side effects, a study has found, leading to new hope for tens of thousands of men.
It is hoped the new treatment, which involves heating only the tumours with a highly focused ultrasound, will mean men can be treated without an overnight stay in hospital and avoiding the distressing side effects associated with current therapies.
A study has found that focal HIFU, high-intensity focused ultrasound, provides the 'perfect' outcome of no major side effects and free of cancer 12 months after treatment, in nine out of ten cases.
Traditional surgery or radiotherapy can only provide the perfect outcome in half of cases currently.
Experts have said the results are 'very encouraging' and were a 'paradigm' shift in treatment of the disease.
It is hoped that large scale trials can now begin so the treatment could be offered routinely on the NHS within five years.
