Low-calorie sweeteners found in diet drinks RAISE the risk of obesity and diabetes by affecting how the body processes sugar

Low-calorie artificial sweeteners found in diet drinks actually 'raise the risk of diabetes and obesity'

Millions rely on them to help them stay thin. But low-calorie artificial sweeteners actually raise the risk of obesity, researchers fear.

The popular sugar alternatives found in diet drinks and in sachets in cafes and restaurants may also increase the odds of diabetes.

The sweeteners under the microscope are saccharin, which is found in Sweet’N Low, sucralose, which is found in Splenda, and aspartame, which is found in many diet drinks.

The Israeli researchers that ‘today’s massive, unsupervised consumption’ of artificial sweeteners needs to be reassessed.

The warning at a time when growing concern about the damage done by sugar is likely to mean more people are switching to artificial alternatives.

British experts urged caution, saying that much of the work was done in mice. But they also said that water is the healthiest drink.

The researchers, from the Weizmann Institute of Science, first showed that all three sweeteners made it more difficult for mice to process sugar.

This is known as glucose intolerance and is important because it raises risk of developing diabetes and obesity.

In a study of almost 400 people, the researchers linked artificial sweetener with being fatter and glucose intolerance.

And, worryingly, volunteers who didn’t normally eat or drink artificially-sweetened foods began to become glucose intolerant after just four days of consumption.

The numbers affected were small – just four out of seven men and women in the trial – but the research overall was judged significant enough to be published in Nature one of the world’s most prestigious scientific journals.

Other experiments suggested the sweeteners do the damage by altering type of bacteria in the gut.

While this might seem odd, some of the bugs that live naturally in our digestive system are very good at breaking down food.

If they thrive on artificial sweeteners, this could lead to more energy being extracted from food and more fat being stored – raising the odds of obesity.

Common diabetes drug metformin could cause thyroid and heart problems, experts warn

A drug widely prescribed to those with diabetes could cause thyroid, heart and a host of other health problems, a study has warned.

Metformin is commonly used to treat type 2 diabetes. It lowers blood sugar levels by reducing glucose production in the liver.

But new research, published in the Canadian Medical Association Journal, found the drug is linked to having an underactive thyroid.

An apple a day could keep obesity away: Granny Smiths promote friendly bacteria helping us feel fuller for longer

Granny Smith apples were found to contain high levels of a compound that promotes good bacteria in the gut, helping people feel fuller for longer

An apple a day keeps the doctor away, goes the saying.

But a new study has found more specifically, that a Granny Smith a day could be the key to preventing obesity.

The bright green, crisp variety helps people feel full, inhibiting the urge to eat.

They were found to promote friendly bacteria, which invokes the feeling of being full.

The study, published in the journal Food Chemistry, revealed that the non digestible compounds in the fruit, which include fibre and polyphenols, do not get broken down by stomach acid.

When they reach the colon they are fermented by bacteria in the colon which helps friendly bacteria in the gut to grow.

Scientists at Washington State University tested several different varieties of apple on mice, to see which caused the most growth of friendly bacteria.

Granny Smiths worked better than Golden Delicious, Gala, Braeburn and other popular varieties, they discovered.

The variety, known for its slightly tart flavour, had a particularly high fibre content and compounds like polyphenols which do not break down when eaten, they reported.

The team analysed mouse droppings after feeding the animals, some of which were obese, different types of fruit.

They discovered the balance of bacteria in the colon of obese people is often 'disturbed' in a way that can disrupt the metabolism and make people feel hungry.

It was revealed that the faeces of overweight mice that had eaten Granny Smith apples had changed and become similar to that of slim mice.

The discovery could lead to future treatments for weight problems.

Think antioxidants will make you live longer? Think again:

We all want to stay as healthy and young-looking as possible, which is why millions of us dutifully take antioxidant supplements such as vitamins C, E and beta-carotene, as well as splashing out on costly antioxidant 'superfoods' such as blueberries.

For years we've swallowed the line from scientists that antioxidants could slow the rate at which our cells - and therefore our bodies - age.

The theory is that antioxidants reduce the 'oxidising' damage caused by free radicals - corrosive molecules produced by our bodies as we process oxygen, and which we also breathe in from polluted air and smoking.

For years we've swallowed the line from scientists that antioxidants could slow the rate at which our cells

It is thought that when these free radicals attack proteins and lipids (fats in the cells), it breaks down the cell membrane and damages the DNA inside. This in turn may cause cancerous mutations, as well as making the cells age more rapidly. Free-radical damage to brain cells is also believed to cause the sort of drops in cognitive functioning associated with ageing.

In Britain, we spend £175 million a year on antioxidant supplements - but a new study suggests we might be wasting our money. Not only do free radicals not cause ageing, say researchers at McGill University in Canada, but taking antioxidant pills may actually make our bodies age faster- making them a short cut to an early grave. So what is going on?

The end of heart disease?

Scientists have discovered a way to block the formation of excess cholesterol that leads to heart disease.

Working with mice and rabbits, Johns Hopkins scientists successfully prevented the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.

The condition develops when fat builds inside blood vessels over time and renders them stiff, narrowed and hardened, greatly reducing their ability to feed oxygen-rich blood to the heart muscle and the brain.

HOW THEY DID IT

Mice used in the experiments were genetically engineered to lack a protein essential in the breakdown of fats and thus were predisposed to atherosclerosis.

The researchers fed the animals a high-fat diet over the course of several months, but also gave a third of the animals a low-dose of D-PDMP.

They gave a double dose of the same inhibitor to another third and placebo to the rest.

These effects were observed in animals on a daily D-PDMP treatment even though they ate a diet made up of 20 percent triglycerides - the human equivalent of eating a greasy burger for breakfast, lunch and dinner.

Researchers identified and halted the action of a single molecular culprit responsible for a range of biological glitches that affect the body’s ability to properly use, transport and purge itself of cholesterol — the fatty substance that accumulates inside vessels and fuels heart disease.

The offender, the researchers say, is a fat-and-sugar molecule called glycosphingolipid, or GSL, which resides in the membranes of all cells, and is mostly known for regulating cell growth.

Results of the experiments, the scientists say, reveal that this very same molecule also regulates the way the body handles cholesterol.

The Johns Hopkins team used an existing man-made compound called D-PDMP to block the synthesis of the GSL molecule, and by doing so, prevented the development of heart disease in mice and rabbits fed a high-fat, cholesterol-laden diet.

The findings, in the journal Circulation, reveal that D-PDMP appears to work by interfering with genetic pathways that regulate fat metabolism on several fronts - from the way cells derive and absorb cholesterol from food, to the way cholesterol is transported to tissues and organs and is then broken down by the liver and excreted from the body.

Scientists invent portable fertility test enabling men to test the quality of their sperm from their own homes

A portable fertility test enabling men to test the quality of their sperm from the privacy of their own homes has been invented by scientists.

Researchers in the US say their easy-to-use kit could be available to consumers as early as next year, meaning men focussed on their fertility issues would no longer have to endure frequent trips to the doctor to test their sperm.

Greg Sommer and Ulrich Schaff, who founded a startup company to develop their device, say the tests can give a result within minutes.

There are endless controversies in the U.S. about contraception, rape and abortion, with politicians and activists of every stripe chiming in endlessly. But there's not much discussion of women dying in childbirth.

Maybe there should be.

A new study released by the University of Washington's Institute for Health Metrics and Evaluation (IHME) and published in the latest issue of The Lancet finds that there are only eight countries in the world where maternal mortality rates have risen since 2003, including Afghanistan, countries in Africa and Central America – and the United States.

In 2013, 18.5 mothers in the U.S. died for every 100,000 live births, compared to 7 deaths per 100,000 in Saudi Arabia, 8.2 in Canada and 6.1 in the United Kingdom.

A Better Prostate Cancer Test Is Here

Until recently, the PSA test for prostate cancer had been a routine part of every middle age man’s physical. But it has fallen out of favor as doctors realized the PSA was leading many men to have needless and painful prostate biopsies and unnecessary cancer treatments.

In fact, major medical groups have stopped recommending routine PSA testing for most men.

But now a better prostate cancer test has become available to help address the problem.

It’s called the 4Kscore Test.
