Fasting Blood Sugar Above 90 Puts You At Risk of Heart Disease

Apr 22, 2002

Study shows a fasting BG of above 100 increases risk of heart disease by 300%. >People with a fasting blood sugar level of 100-125 mg/dl had an adjusted nearly 300% increase higher risk of having coronary heart disease than people with a level below 79 mg/dl. This information was compiled from a cross-sectional study of nearly 2500 people.

A fasting blood sugar level of more than 125 mg/dl is the current threshold for identifying patients with diabetes. But the new finding suggests that patients with high levels of blood sugar in the nondiabetic range face a substantial risk of coronary heart disease.


The Cleveland Clinic Foundation now uses a fasting blood sugar of 90 mg/dl or higher as a biomarker of coronary heart disease risk. The Cleveland Clinic gets very concerned when they someone with a fasting blood sugar above 90 mg/dl. They try to intervene with exercise, diet and weight control.

The previous cutoff of 125 mg/dl was based on the incidence of diabetic retinopathy, but physicians now increasingly focus on the diabetes-related risk of coronary heart disease. As evidence continues to grow in this area it is likely the definition of diabetes will change.


Normal fasting blood glucose is below 100 mg/dl. A person with pre-diabetes has a fasting blood glucose level between 110 and 125. If the level rises to 126 or above, a person has full-blown diabetes.

Why should we wait for a patients blood sugar to get to 100 before we are concerned?

Pre-diabetes is far easier to turn around in the earlier stages than the later stages.

It is important to recognize that the new recommendations are for everyone over 44 years of age to have a fasting blood sugar as a screen. If you are overweight you should also have it every year.

Amazingly, 25% of obese children under ten had either blatant or pre-adult onset type 2 diabetes. One quarter of the obese children under 10 in the US may have diabetes.

So, it is never to early to screen for diabetes in obese individuals.

The top medical journal, NEJM in May 2001 proclaimed that in fact one can "cure" type two diabetes with diet and exercise.

The dietary modifications were able to reduce the rate of diabetes by nearly 60% and they did that without even understanding some of the most basic foundational truths of food choices. These investigators were absolutely clueless with respect to the influence of grain and sugar restriction on insulin optimization.

So if the traditionally recommended low-fat diet can reduce diabetes by 60%, if one uses the modified food choice program you can reduce type two diabetes by well over 95%.

Exercise is unquestionably also a big key here.

Considering that there are 15 million diabetics in the US and the epidemic is continuing to increase in the US and worldwide (affected about 6 percent of persons in developed countries in 1995), this is important information.
