Researchers at the Johns Hopkins Bloomberg School of Public Health believe that lowering blood glucose levels could reduce the risk of coronary heart disease in both diabetics and non-diabetics.

The researchers found that hemoglobin A1c ( HbA1c ) - a measure of long-term blood glucose level - predicts heart disease risk in both diabetics and non-diabetics.

An elevated blood glucose level is the defining feature of diabetes, but until now it was unclear whether elevated glucose levels contributed independently to increasing heart-disease risk.

The study is published in the Archives of Internal Medicine.

"Our results suggest that improving blood-glucose control may reduce heart disease risk," said Elizabeth Selvin, lead author of the study and at Bloomberg School of Public Health's Department of Epidemiology.

For non-diabetics, lifestyle modifications, such as increased physical activity, weight loss and eating a healthful, low-glycemic, index diet rich in fiber, fruit and vegetables, may not only help prevent diabetes, but also reduce the risk of heart disease," she said.


Comment: A diet rich in fiber, fruit and vegetables is a diet rich in sugar. This has been the standard dietary recommendations for decades, resulting in a historical unprecedented health catastrophe which didn't existed before. It is a diet low in carbs and rich in animal fats the one which cures diabetes and lowers your risk for cardiovascular disease. See:

The researchers used data from the Atherosclerosis Risk in Communities Study ( ARIC ), a community-based cohort of almost 16,000 people from four states - North Carolina, Mississippi, Maryland and Minnesota.

HbA1c levels were taken from ARIC study participants during clinical examinations in 1990-1992. ARIC researchers tracked study participants for 10-12 years to acquire coronary heart disease events, hospitalizations and deaths.

In participants with diabetes, the researchers found an association between HbA1c and increasing coronary heart disease risk.

Each 1-percentage-point increase in HbA1c level was associated with a 14 percent increase in heart disease risk.


Comment: The best way to increase your HbA1c levels is by increasing your dietary intake of sugar and carbs, regardless of its source. By the time your gut ends up digesting all those "healthy" carbs, it is all sugar in your bloodstream.


According to the study, the current target for "good" glycemic control established by the American Diabetes Association is an HbA1c value less than 7 percent. However, the researchers' analyses suggest that heart disease risk begins to increase at values even below 7 percent.

They found that those study participants without diabetes but who had " high normal " HbA1c levels ( approximately 5 percent to 6 percent ) were at an increased heart disease risk, even after accounting for other factors such as age, cholesterol level, blood pressure, body mass index and smoking.

Non-diabetic persons with HbA1c levels of 6 percent or higher had almost a two-fold greater heart disease risk compared to persons with an HbA1c level below 4.6 percent.

The results suggest we should be concerned about elevated blood sugar levels in non-diabetics as well as diabetics. An important next step is to incorporate strategies for lowering HbA1c.
