Exercise rivals Medication for Heart Disease.
Exercise can be as good a medicine as pills for people with conditions such as heart disease, a study has found.
- Can reduce your risk of major illnesses, such as heart disease, stroke, diabetes and cancer by up to 50%.
- Can lower your risk of early death by up to 30%.
- Can boost self-esteem, mood, sleep quality and energy as well as keep weight off.
- Moderate activity, such as cycling or fast walking, gives your heart and lungs a work-out
The work in the British Medical Journal looked at hundreds of trials involving nearly 340,000 patients to assess the merits of exercise and drugs in preventing death.
Physical activity rivalled some heart drugs and outperformed stroke medicine.
The findings suggest exercise should be added to prescriptions, say the researchers. Continue reading Exercise rivals Medication for Heart Disease.

Vegetarians “Cut heart risk by 32%”
Ditching meat and fish in favour of a vegetarian diet can have a dramatic effect on the health of your heart, research suggests.
A study of 44,500 people in England and Scotland showed vegetarians were 32% less likely to die or need hospital treatment as a result of heart disease.
Differences in cholesterol levels, blood pressure and body weight are thought to be behind the health boost.
The findings were published in the American Journal of Clinical Nutrition.
Heart disease is a major blight in Western countries. It kills 94,000 people in the UK each year – more than any other disease, and 2.6 million people live with the condition. Continue reading Vegetarians “Cut heart risk by 32%”
Beta-Blockers don’t appear to Work
They have treated heart disease for 40 years, but it now seems that beta blockers don’t work. What went wrong?
IT IS very rare for new evidence to question or even negate the utility of a well-established class of drugs. But after four decades as a standard therapy for heart disease and high blood pressure, it looks like this fate will befall beta blockers. Two major studies published within about a week of each other suggest that the drugs do not work for these conditions. This is a big surprise, with big implications.
The first beta blocker, Inderal, was launched in 1964 by Imperial Chemical Industries for treatment of angina. This drug has been hailed as one of great medical advances of the 20th century. Its inventor, James Black, was awarded the Nobel prize in medicine in 1988.
The 20 or so beta blockers now on the market are very widely used – almost 200 million prescriptions were written for them in the US in 2010. They are standard issue for most people with heart disease or high blood pressure. This may now change.
A large study published last month in The Journal of the American Medical Association found that beta blockers did not prolong the lives of patients – a revelation that must have left many cardiologists shaking their heads (JAMA, vol 308, p 1340). Continue reading Beta-Blockers don’t appear to Work
Is Alzheimers Disease Type 3 Diabetes ?
THE human brain evolved to seek out foods high in fat and sugar. But a preference that started out as a survival mechanism has, in our age of plenty, become a self-destructive compulsion.
It is well known that bad diets can trigger obesity and diabetes. There is growing evidence that they trigger Alzheimer’s disease too, and some researchers now see it as just another form of diabetes.
If correct, this has enormous, and grave, implications. The world already faces an epidemic of diabetes. The prospect of a parallel epidemic of Alzheimer’s is truly frightening, in terms of human suffering and monetary cost.
This outcome will not be easily averted. Few people need to be told that too much high-fat, high-sugar food is a health hazard. And yet sales of fast food remain healthy (or should that be hefty?). Part of the reason is “future discounting”, another evolved feature of the human brain that makes us value short-term rewards over long-term risks.
What can be done? One option is to call in the lawyers. Some moderately successful attempts have already been made to sue food companies for their role in creating the obesity epidemic. If a causal link between fatty, sugary food and Alzheimer’s can be established, it is highly likely that more lawsuits will follow. Such actions have their place, but this is a laborious and expensive way to enact change.
Nor do the policy levers at our disposal appear promising. Public awareness campaigns have been of limited use in reversing the tide of obesity. Will the added threat of dementia prove harder to ignore? “Sin taxes” on unhealthy foods may work – Denmark and a handful of other countries are experimenting with them – but it is not yet clear whether they make any real difference. What’s more, they raise questions about personal responsibility and nanny-statism.
We may be left with only the option of medically blocking either the craving for fast food, or its consequences. That has its own complications, and sidesteps the problem rather than addressing it. But the human brain also evolved to find ingenious solutions to intractable problems. It may yet come to its own rescue. Continue reading Is Alzheimers Disease Type 3 Diabetes ?
Exercise – Probably the best Medicine of all
From dementia and diabetes to high blood pressure – no pill protects us against ill health like exercise does.
A plethora of recent studies shows that exercise protects us from heart attacks, strokes, diabetes, obesity, cancer, Alzheimer’s disease and depression. It even boosts memory. And it has the potential to prevent more premature deaths than any other single treatment, with none of the side effects of actual medication. “It’s a wonder drug,” says Erik Richter, a diabetes researcher at the University of Copenhagen, Denmark. “There’s probably not a single organ in the body that’s unaffected by it.”
Throughout evolution, humans have been active. Our ancestors chased prey as hunter-gatherers and fled from predators. More recently, they laboured on farms and in factories. But the decline of agricultural and industrial labour, plus the invention of the car, a multitude of labour-saving devices and – most perniciously – TV, computers and video games, mean we’ve all ground to a sudden and catastrophic standstill.
“We were built to be active, but the way our environment has changed and the way we live our lives has led us to become inactive,” says Christopher Hughes, senior lecturer in sport and exercise medicine at Queen Mary, University of London.

Michael Mosley on intermittent Fasting
Scientists are uncovering evidence that short periods of fasting, if properly controlled, could achieve a number of health benefits, as well as potentially helping the overweight, as Michael Mosley discovered.
I’d always thought of fasting as something unpleasant, with no obvious long term benefits. So when I was asked to make a documentary that would involve me going without food, I was not keen as I was sure I would not enjoy it.
But the Horizon editor assured me there was great new science and that I might see some dramatic improvements to my body. So, of course, I said, “yes”.
I am not strong-willed enough to diet over the long term, but I am extremely interested in the reasons why eating less might lead to increased life span, particularly as scientists think it may be possible to get the benefits without the pain.
How you age is powerfully shaped by your genes. But there’s not much you can do about that.
Calorie restriction, eating well but not much, is one of the few things that has been shown to extend life expectancy, at least in animals. We’ve known since the 1930s that mice put on a low-calorie, nutrient-rich diet live far longer. There is mounting evidence that the same is true in monkeys.
