Even if a doctor assures you that your blood sugar is “normal,” alarming evidence documents that you are at significant risk of premature death unless you achieve optimal 24-hour-a-day glucose control.
Life Extension® long ago warned of the silent dangers when fasting blood sugar exceeds 85 mg/dL. New scientific studies validate this position.
Even more insidious are data showing that blood sugar “spikes”that occur after each meal dramatically increase the risk of cardiovascular disease, retinal damage, and cancer.
Unless steps are taken to suppress after-meal sugar surges, every large meal you eat can trigger a dangerous metabolic cascade that results in cell damage and accelerated aging.
Fortunately, proven methods exist to support optimal blood sugar throughout the day.
The latest is a green coffee bean extract that targets a critical enzyme involved in after-meal blood sugar spikes. When tested on humans in a placebo controlled study, this natural extract produced an astounding 32% drop in after-meal blood sugar
An Epidemic of Elevated Blood Sugar
The percentage of adults who suffer chronic high blood sugar is staggering!
One report evaluated 46,000 middle-age individuals and found more than 80% had fasting blood sugar of 85 mg/dL or greater.
Another study involving 11,000 middle-age and older individuals showed more than 85% had fasting blood sugar of 85 mg/dL or greater.
Since incidence of disease starts to increase when fasting blood sugar rises above these levels, this means the vast majority of aging humans today endure chronic cellular damage associated with elevated blood sugar.
This epidemic of elevated blood sugar will accelerate age-related disease until the medical profession realizes that their test values for defining “normal” blood sugar are horrifically defective.
Mainstream Medicine’s Fatal Flaws
There are two major problems with the way mainstream medicine views blood sugar.
First, the “normal” range for fasting blood sugar is still set too high. Current criteria specify that you are not “diabetic” unless fasting blood glucose exceeds 125 mg/dL. The range between 100 and 125 mg/dL is considered “pre-diabetic.” In other words, with a blood sugar reading of 99 mg/dL, your doctor will tell you everything is fine and send you home ignorant of the dangers lurking within your body.
Recall that optimal glucose control occurs when fasting blood glucose is kept between 70 and 85 mg/dL. This means that fasting glucose levels that doctors accept today as “normal” are in reality dangerously elevated.
Second, mainstream doctors do not tell their patients about the risks of after-meal (postprandial) blood sugar spikes. After every meal, these sudden surges in blood sugar damage delicate blood vessels in your brain, heart, kidneys, and eyes, as well as accelerate the aging of cells and tissues throughout your body.
Utilizing only fasting blood glucose readings does not detect perilous after-meal glucose spikes that present an increased risk of death. The critical truth is that standard definitions of diabetes are dangerously outdated.
Scientific research shows that after-meal spikes in blood sugar are potentially more damaging than elevations of fasting blood sugar. For example, in people with “normal” blood sugars and “normal” glucose tolerance tests, the risk of a heart attack increases by 58% for each 21 mg/dLincrease in after-meal blood sugar. And for a similar after-meal glucose elevation, risk of dying from cardiovascular disease increases by 26%. Control of after-meal glucose needs to be recognized as a critical component in reduction of cardiovascular complications.
What doctors don’t realize is that an isolated fasting glucose reading fails to provide information on their patients’ glucose control throughout the day. So when a patient has a fasting glucose reading of, let’s say, 95 mg/dL, this may be an artificially low number that does not reflect the patient’s real-world, all-day glucose status that may be considerably higher.
For instance, a patient with a 95 mg/dL fasting glucose reading may spend most of their day significantly above 150 mg/dL, as their aging body is unable to neutralize the impact of the excess calories they chronically ingest.
Without controlling fasting and postprandial sugar spikes, the stage is set for accelerated aging and a series of degenerative diseases.
Why We Are Predisposed to Elevated Glucose
If blood sugar ever drops too low, death rapidly ensues as brain cells cannot function long without adequate glucose. To protect against acute death in the near-starvation state our ancestors encountered, the body developed compensatory mechanisms to ensure that glucose levels don’t fall too low.
The problem with these protective mechanisms is that they cause the majority of aging people today to suffer dangerously elevated blood sugar, as widespread famine no longer exists in modern societies.
How Chronic Glucose Overload Occurs
The liver stores sugar (glucose) in a form called glycogen and releases just enough to maintain a steady blood sugar level. In healthy individuals, this process of glucose release (called glycogenolysis) is suppressed after a meal to prevent blood sugar levels from rising excessively.
While glycogenolysis protected our ancestors from acute starvation and death, the impact on people today is the opposite. As we age, this internal control mechanism (glycogenolysis) malfunctions, resulting in dangerously high blood glucose levels.
Another factor causing elevated glucose involves excess creation of new glucose in the body. In healthy people, a biochemical process known as gluconeogenesis creates new glucose from other substances such as amino acids when blood sugar levels are too low. Aging people often make too much glucose from all kinds of foods, even when blood glucose levels are already too high.
Contrary to popular belief, carbohydrates are not the only food source of blood sugar. Amino acids found in protein readily convert to blood glucose via gluconeogenesis.
An enzyme involved in gluconeogenesis and glycogenolysis is glucose-6-phosphatase.
With increasing age and rising blood sugar levels, control of glucose-6-phosphatase can become impaired. When this occurs, glucose-6-phosphatase increases the release of stored glucose from the liver (glycogenolysis) and enhances glucose creation (gluconeogenesis)…despite already sufficient after-meal blood sugar levels.
Excess activity of glucose-6-phosphatase is why many aging people find it nearly impossible to achieve optimal glucose levels. Compounds that target glucose-6-phosphatase are being aggressively sought to counter a diabetes epidemic that has nearly tripled in the United States over the past three decades.
Since conventional medical authorities are still not diagnosing patients as “diabetic” until they show fasting glucose over 125 mg/dL or after-meal glucose over 199 mg/dL, the true number of people today whose health is being destroyed by high blood sugar remains grossly underestimated.
For example, data indicate the risk for stroke increases as fasting glucose increases above 83 mg/dL. In fact, every 18 mg/dL increase beyond 83 results in a 27% greater risk of dying from stroke. So failing to aggressively lower glucose levels is exposing the vast majority of the American population to the leading cause of long-term disability and third highest cause of death, i.e., stroke.
Even adherence to a calorie-reduced diet, or a low-carbohydrate diet, does not always protect against skyrocketing glucose levels triggered through glucose-6-phosphatase.
To summarize, the two internal factors that conspire to elevate glucose levels are:
- Glycogenolysis—Release of stored glucose from the liver.
- Gluconeogenesis—Creation of new glucose from non-carbohydrates.
Excess expression of glucose-6-phosphatase is involved in glycogenolysis and gluconeogenesis. Suppression of glucose-6-phosphatase offers a crucial strategy for limiting the destructive impact of elevated after-meal blood sugar.
Combating Excess Glucose with Chlorogenic Acid
In the quest for natural ways to safely inhibit after-meal blood sugar spikes, scientists turned their attention to plant compounds that target the glucose-6-phosphatase enzyme.
Pharmaceutical researchers have been eager to discover a drug that would target after-meal blood sugar spikes. Ideally, this drug would suppress glucose-6-phosphatase, which is involved in new glucose formation and release of glucose from its storage site in the liver.
Exciting new findings show a natural compound within the green coffee bean known as chlorogenic acid can modulate after-meal blood sugar surges.
As a multitude of studies show, coffee consumption is associated with a reduced risk of type 2 diabetes. We now understand chlorogenic acid in coffee exerts significant anti-diabetic properties. And as recent studies show, 80-85% of the adult population is at risk for diabetic complications because their blood glucose levels are too high!
Green Coffee Extract Improves Glucose Control
Green coffee bean extract found in unroasted coffee beans, once purified and standardized, produces high levels of chlorogenic acid and other beneficial polyphenols that can suppress excess blood glucose levels.
The research findings on the impact of chlorogenic acid on blood sugar are impressive. For starters, a team of Japanese researchers recorded a 43% drop in blood sugar levels after administering green coffee bean extract to mice after a heavy meal.
Human clinical trials support the role of chlorogenic acid-rich green coffee bean extract in promoting healthy blood sugar control and reducing disease risk.
Aware of the crucial importance of controlling after-meal blood sugar spikes, scientists conducted a study among 56 healthy volunteers, challenging them with an oral glucose tolerance test before and after a supplemental dose of green coffee extract. The oral glucose tolerance test is a standardized way of measuring a person’s after-meal blood sugar response.
In subjects not taking green coffee bean extract, the oral glucose tolerance test showed the expected rise of blood sugar to an average of 144 mg/dL after a 30 minute period. But in subjects who had taken 200 mg of the green coffee bean extract, that sugar spike was significantly reduced, to just 124 mg/dL—a 14% decrease
That impressive difference was sustained throughout the two-hour study period at a dose as low as 200 mg of green coffee bean extract. Subjects had a mean 19% reduction of blood sugar at one hour, and a 22% reduction (glucose down to just 89 mg/dL) at two hours, compared to each patient’s own untreated levels. In other words, the amount of time subjects had glucose levels in the dangerous range was sharply curtailed by the green coffee bean extract
To state this differently, when subjects did not take the green coffee bean extract, their oral glucose tolerance reading after two hours showed blood sugar of 115 mg/dL—a higher-than-desirable level. In response to a modest dose of 200 mg of green coffee bean extract, two-hour blood sugar levels dropped to only 89 mg/dL
For most aging individuals, even after eating nothing for eight to twelve hours, it is challenging to achieve a “fasting” glucose reading as low as 89 mg/dL. Yet when these study subjects took 200 mg of green coffee bean extract, their glucose levels dropped to 89 mg/dL just two hours after drinking a pure glucose solution. The high-dose glucose drink used in standard oral glucose tolerance tests spikes blood sugar more than typical meals.
When a higher dose (400 mg) of green coffee bean extract was supplemented before an oral glucose challenge test there was an even greater average reduction in blood sugar—up to nearly 28% at one hour!
How Green Coffee Bean Extract Suppresses Glucose Elevation
Scientists have discovered that chlorogenic acid found abundantly ingreen coffee bean extract inhibits the enzyme glucose-6-phosphatase that triggers new glucose formation and glucose release by the liver. As discussed earlier, glucose-6-phosphataseis involved in dangerous after-meal spikes in blood sugar.
Another means by which chlorogenic acid acts to suppress after-meal glucose surges is by inhibiting alpha-glucosidase. This intestinal enzyme breaks apart complex sugars and enhances their absorption into the blood. Slowing the absorption of common sugars (including sucrose) limits after-meal glucose spikes.
In yet another significant mechanism, chlorogenic acid increases the signal protein for insulin receptors in liver cells. That has the effect of increasing insulin sensitivity, which in turn drives down blood sugar levels.
Chlorogenic acid-rich plant extracts have been shown to reduce fasting blood glucose values by more than 15% in diabetic patients with poor response to medication.31 A similar effect was seen in healthy volunteers, whose intestinal absorption of glucose was reduced following a chlorogenic acid-enriched coffee drink.
When a chlorogenic acid supplement of 1 gram was given before meals, glucose levels were reduced by 13 mg/dL, just 15 minutes after an oral glucose challenge, demonstrating its ability to rapidly lower the after-meal blood sugar spike in humans.
In a clinical trial, researchers gave different dosages of green coffee bean extract, standardized for chlorogenic acid, to 56 people. Thirty-five minutes later, they gave the participants 100 grams of glucose in an oral glucose challenge test. Blood sugar levels dropped by an increasingly greater amount as the test dosage of green coffee bean extract was raised, from 200 mg up to 400 mg. At the 400 mgdosage, there was a full 24% decrease in blood sugar—just 30 minutes after glucose ingestion.
This means that if you had a dangerous after-meal glucose reading of 160 mg/dL, green coffee bean extract would slash it to 121 mg/dL.
These findings are in line with supportive data demonstrating green coffee bean extract‘s numerous blood sugar-reducing mechanisms of action.
Other experimental models reveal that chlorogenic acid favorably modulates gene expression to enhance the activity of liver cells and increase levels of the hormone adiponectin, which enhances insulin sensitivity and exerts anti-inflammatory, anti-diabetic, and anti-atherogenic effects.
The need to redefine diabetes is critical because risk of premature death and disease rises sharply with fasting blood sugar greater than 85 mg/dL.
Furthermore, the insidious impact of after-meal blood sugar spikes goes largely undetected, exposing the vast majority of people to accelerated disease risk.
Behind this danger is the little-appreciated role of glucose-6-phosphatase in creating and releasing additional glucose into the blood. This enzyme, which helps regulate blood sugar when you’re young, can inappropriately trigger a dangerous after-meal surge of blood sugar as you age.
Avant-garde scientists have identified a breakthrough weapon to control these surges: green coffee bean extract. This natural ingredient contains a compound called chlorogenic acid shown to target glucose-6-phosphatase and blunt post-consumption blood sugar levels by up to 32%.
A consistent finding in those who restrict their calorie intake is markedly lower blood glucose levels. Longevity enthusiasts can now benefit from a novel yet natural green coffee bean extract to combat internal processes that cause dangerous elevations in blood glucose.
