Herbal diabetes discovery: Chinese herb slashes blood sugar by 50 percent in three weeks

(NewsTarget) Researchers at Sydney's Garvan Institute have discovered that berberine, a Chinese herb, can significantly lower blood sugar levels in diabetics.

 Chinese, Korean and Australian scientists administered the herb -- traditionally used to treat diarrhea and heal wounds -- to rats and found that after three weeks, the rats' blood sugar levels had dropped by 50 percent.

Diabetes is largely brought on by poor lifestyle choices that result in too much glucose in the blood which prevents insulin, the hormone that regulates blood sugar, from properly doing its job. The researchers' study, published in the journal Diabetes, says that berberine helps insulin work more efficiently so that it can successfully lower levels of blood sugar.

Conventional medical doctors usually treat the disease with pharmaceuticals such as metformin and thiazolidinedione, which can have harmful side effects. Professor David James, head of Garvan's diabetes and obesity research program, says drug firms and the medical community recognize the need for safer alternatives to traditional diabetes drugs.

"There's a tremendous need for new therapies and here we are with a new one on the table," says James. "This is very exciting because clearly (diabetes is) a growing problem and now we're looking at a new weapon in our armory in the fight against it."

"Type 2 diabetes is easily managed or even outright cured with natural medicine," added Mike Adams, a consumer health advocate. "Berberine is only the latest in a long line of herbs with documented blood sugar lowering effects, including cinnamon, gymnema, banaba, bitter melon and many others."

Chronic disease management: Drug shareholders�?goldmine 
   

 by Alan Cassels

The job description of your average physician keeps getting bigger. If you are sick, you go to the doctor. If you are worried that you might be getting sick, you go to the doctor. If you aren’t sick and want assurances how to stay that way, you go to the doctor. In the paradigm of modern medical care we’ve set up, a doctor is your first, or primary, contact with the system. That’s why we call their services “primary care.�?

One way that medical authorities around the world are trying to improve the world for primary care physicians has been the creation and embrace of chronic disease management (CDM) to help physicians manage patients with long-term, unremitting diseases such as asthma, arthritis and diabetes.

CDM has its champions and detractors, yet curiously, it almost never makes the news. Until recently. In early January, the Vancouver Sun seized on some remarks related to CDM, made by former BC deputy minister of health, Dr. Penny Ballem. By most accounts, a hard working, competent and long serving deputy minister, she quit the Campbell government in 2006, citing the BC Liberals inability to set “quality targets�?with doctors.

Given that most truth gets disfigured when chewed on by media hounds, and this story is likely no exception, what caught my attention was the following quote attributed to her: “Only about 40 percent of diabetics in BC were getting good care.�?This is described as “guideline-based optimal care,�?a practice where physicians systematically monitored and managed the care of their diabetic patients. Calling the situation in BC “atrocious,�?with media-grabbing candor rarely seen displayed by health bureaucrats, Ballem said that such inattentive care was responsible for “killing people.�?/FONT>

Canadian doctors find diabetes advance

TORONTO (UPI) -- Researchers in Canada said they identified the role pain nerves in insulin-producing cells may play in preventing and reversing diabetes in mice.

The work "led us to fundamentally new insights into the mechanisms of this disease," Michael Salter, of Toronto's Hospital for Sick Children and a co-lead investigator, said in a news release.

Researchers said they learned that pain receptors don't secrete enough chemical elements found in the brain to keep insulin-producing pancreatic islets working normally. By supplying the chemical element to diabetic-prone mice, "the research group learned how to treat the abnormality ... and even reversed established diabetes," Salter said.

Researchers were tracking links between Type 1 diabetes and the nervous system when they found what they said was a control circuit between the islets that produce insulin and associated pain nerves. This circuit keeps the islets operating normally. When they investigated further, researchers found specific sensory neurons didn't secrete enough neuropathies to sustain normal functions, which in essence, created stress.

The researchers extended the studies to Type 2 diabetes. They said they believed treating the islet-sensory nerve circuits could normalize insulin resistance.

If symptoms are noticed early enough, type 2 diabetics won’t need to be given artificial insulin as long as they strictly control their intake of carbohydrates. So, because of this type of diabetes, nutritionists have had to look at carbohydrates in a new light, which has led to a major rethink about the causes of diabetes.

What causes diabetes? Originally, nutritionists analysed foods by the amount of energy they provided - in other words, their calories. Calorie levels were worked out in the laboratory rather crudely by burning foods and seeing how much heat energy they produced.

However, caloric measures are useless for diabetics, who need to know the glucose value of foods to enable them to control their blood glucose levels through their diet, and so avoid the need for insulin injections. But the glucose values of foods can’t be measured in the laboratory; they must be tested on live human beings.

So, in a painstaking series of tests carried out in the 1980s, every foodstuff was analysed for its potential to produce glucose in the bloodstream. Human guinea pigs were fasted to create a baseline to measure against, then given a single food to eat. Regular blood samples were taken over four hours to chart the changes in blood glucose levels.

The results didn’t turn out quite as expected. One surprise was the finding that all carbohydrates cause a glucose peak roughly 30 minutes after ingestion. Previously, it had been thought that simple carbohydrates (like sugar and honey) were fast-acting while complex carbohydrates (like potatoes and cereals) were slow-acting.

Nevertheless, there were dramatic differences between carbohydrates in the levels of blood glucose they produced. And as the technical term for blood glucose is glycaemia, the differences between carbohydrates were measured in terms of a ‘glycaemic index�?(GI): the higher the number, the greater the amount of blood glucose produced by the food.

Nutritionists arbitrarily gave glucose itself a GI of 100 and, not surprisingly, virtually all foods are lower than that (see box, p 4). Also as expected, the most refined carbohydrates led to the highest blood glucose levels - but there were some surprises. Cooking was found to have major effects on the GI. Carrots, for example, produce three times the blood glucose level when cooked rather than eaten raw. In fact, any cooking or processing raises the GI significantly.

The GI has now been used by French scientist Dr Michel Montignac as the basis of a successful slimming regime - although, arguably, his greater contribution to health has been to develop a new theory of the causes of diabetes.
 

His interest was sparked by a paper published in 1979 by Dr B. Jeanrenaud, who found that all obese people suffered from 'a form of hyperinsulinemia' (Diabetologia, 1979; 17: 133-8). Hyperinsulinaemia is when the pancreas overreacts to excess glucose by producing too much insulin. At the time, nutritionists looking at Jeanrenaud’s data concluded that hyperinsulinaemia was the cause of obesity - but Montignac wasn’t so sure.

Taking a sideways look at the theory, Montignac proposed that the overproduction of insulin is not caused by obesity, but by a faulty pancreas - which itself causes obesity.

Montignac’s theory remained in the wilderness until 1988, when two other French scientists discovered that hyperinsulinaemia caused 'abnormally large amounts of recently consumed fat' to be laid down in the body (Creff EF, Obésités, Paris: Masson, 1988).

Here, then, was a plausible mechanism for obesity, one that would help explain why some people become fat while others do not, even with exactly the same food intake. Obese people, the new findings suggested, are not secret guzzlers - they have a pancreas that produces too much insulin.

What were the implications of this for diabetes? Montignac theorised that the reason most people with adult-onset (type 2) diabetes are obese is not, as most people thought, because obesity causes diabetes. Rather, obesity and diabetes are two sides of the same coin - both are manifestations of the same underlying problem: hyperinsulinaemia resulting from a faulty pancreas.

So, does too much insulin cause diabetes? No, said Montignac, it’s a symptom of an overworked pancreas. It’s the end result of a state of almost continuous hyperglycaemia (excess glucose in the blood), which places too high a demand on the pancreas to produce insulin. Eventually, the system goes into overdrive, creating a near-constant surplus of insulin. This, in turn, causes ‘insulin resistance�? where insulin ‘switch-off�?cells overload and cease to respond, further tightening the vicious circle.

Diabetes is, therefore, due to pancreas exhaustion, says Montignac, caused by a diet containing too many carbohydrates with a high glycaemic index. He puts the blame fairly and squarely on the modern Western diet, with its high content of refined carbohydrates and sugar.

When Montignac first proposed the theory, few experts supported him. Indeed, the prevailing theory was - and still is - that sugar does not cause diabetes. However, the evidence has been mounting that he may be right.

In 1997, researchers at the Harvard School of Public Health reported the results of a study of 65,000 middle-aged women followed for over six years, by which time, over 900 of them were diabetic.

What marked those women who developed diabetes out from the others who hadn’t developed diabetes was their diet, which mostly consisted of low-fibre foods and refined carbohydrates.

Looking at individual foods, the chief culprits were found to be 'cola beverages, white bread, white rice, french fried potatoes, and cooked potatoes' - the very foods listed by Montignac as having a high GI. These foods more than doubled the risk of diabetes.

The Harvard researchers unequivocally supported Montignac’s theory: 'hyperinsulinemia . . . is one of the best predictors of [type 2 diabetes]', they wrote. 'Our findings support the hypothesis that a diet with high glycemic load and a low cereal fiber content increases risk of [type 2 diabetes]' (JAMA, 1997; 277: 472-7).

Virtually identical results were found by the same team in a parallel study of more than 40,000 men (Diabetes Care, 1997; 20: 545-50).

These findings are the first conclusive evidence that the major cause of adult-onset diabetes is a Western diet. Thanks to Montignac, we also now have a cogent theory to explain why it happens. It is now clear that people develop diabetes in middle-age not because of obesity, a sedentary lifestyle or stress (the conventional explanations); they become diabetic because of half a lifetime’s assault on the pancreas by a diet of refined carbohydrates and processed foods.

A dietary time bomb But that’s not the end of the story. Adding a further twist of the knife, the Harvard nutritionists recently found even more evidence to condemn the modern diet. Analysing their data on the 65,000 women, they discovered another dietary risk factor - trans fatty acids. Also called hydrogenated fats, these are liberally added to processed foods to 'improve texture'. Such fats appear to increase the risk of type 2 diabetes 'substantially' (Am J Clin Nutr, 2001; 73: 1019-26).

As yet, there is no explanation for why hydrogenated fats cause diabetes. But this latest evidence, taken with the earlier findings for refined carbohydrates, is a damning explanation for the huge rise in diabetes in the young. It is yet another health time bomb lobbed at us by the food industry, as if cancer and heart disease are not already enough.

Another risk factor for the disease may be milk. Ten years ago, evidence was already accumulating that babies fed on cow’s milk formulas are more likely to develop type 1 diabetes (Diabetes Care, 1994; 17: 13-9). Although the increased risk seems relatively small, it is magnified among children with diabetic siblings.

A Finnish study has shown that feeding such infants cow’s milk formula during early infancy results in a fivefold increase in the risk of diabetes (Diabetes, 2000; 49: 912-7).

Why this should happen is not completely understood, but the culprit is believed to be the insulin content of cow’s milk, which makes the infant create human antibodies to the bovine insulin. The theory is that the baby’s insulin antibodies then react against the insulin-producing cells in the pancreas, thus damaging the cells and triggering type 1 diabetes (Diabetes, 2000; 49: 1657-65).

Factors in cow’s milk have also been suggested as the reason why type 1 diabetes is more prevalent in the northern Europe. In such countries, Friesian cows predominate as they are more suited to colder, wetter climates. It is believed that the milk of Friesian cows may contain a diabetes-precipitating protein that other cow species do not produce.

Nevertheless, that is only one of many theories regarding the environmental causes of type 1 diabetes, which still remain obscure.

However, type 2 diabetes is now much less mysterious - thanks largely to the pioneering work of Dr Michel Montignac and the remarkable way he has stood conventional thinking about the disease on its head. Tony Edwards
