There are two different tests your doctor can use to measure your blood glucose to determine if you have pre-diabetes or diabetes: the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT). The FPG test is a blood test that determines the amount of glucose (sugar) in the blood after an overnight fast (not eating for at least 8 hours). With the OGTT test, a person's blood glucose level is measured after fasting and then 2 hours after drinking a glucose-rich beverage. See the chart below for the ranges of blood sugar levels and how they are used to diagnose pre-diabetes and diabetes. Fasting blood glucose: A method for learning how much glucose (sugar) there is in a blood sample taken after an overnight fast.
Blood Glucose Levels: Testing and Normal RangeSeveral different types of blood glucose tests are used. To learn more about Type I diabetes, and Type II diabetes, visit our Health articles and Pharmacy news section today! Have you ever noticed how many terms of endearment are based around the notion of “sweetness”? The findings were aired on 60 Minutes and revealed the overwhelming consensus that excessive sugar consumption is strongly linked to many age-related diseases.
Statistics show we now have a not-so-sweet epidemic on our hands: 79 million American adults have blood sugar levels that, while still in the normal range, are too high — and a warning sign for further problems. Unfortunately, you may not even know you have this problem unless your doctor has tested your fasting blood glucose levels. The final destination of a journey is not, after all, the last item on the agenda, but rather some understanding, however simple or provisional, of what one has seen. In these modern times, with the plethora of blood-sugar-related diseases, we need tools like GI and GL to help us understand ways to control blood sugar.
The self-testing, graphic approach to food testing developed in the balance of the newsletter is a less scientific but a more dynamic way to explore postprandial (post-meal) blood glucose levels (BGLs).
GI measures the blood glucose impact of foods eaten in isolation, yet we rarely consume foods this way.


GI readings vary with the individual—blood sugar and insulin reactions are more extreme for diabetics, for example (See Charts 2A and 2B). GIs are calculated in the science lab as the day’s first meal after a 12-hour fast and using a fixed serving that includes 50 grams of carbohydrate.  Most of our daily calories, however, are consumed in combination and throughout the day, when our blood sugar is affected by other foods that we have eaten earlier, as well as by our level of activity. Of the following numbered charts, the first three are based upon scientific research journal articles (Charts 1, 2A, 2B), while the last four (Charts 3-6) are constructed from my own self-testing of foods4 using a simple blood glucose monitor. Chart 1:  Blood Sugar Curves of White Bread Compared to Bread with Added Fiber, Sourdough, and Vinegar. Chart 3:  Instant Oatmeal, Whole Oats (Soaked and Not Soaked), and Whole Oats Combined with a Protein and Fat.
To fully appreciate the impact of two back-to-back carbohydrate breakfasts please notice that the scale used for Chart 6 is twice that of Charts 3-5.
Resetting the Table–to Control Blood Sugar (For a discussion of other strategies, see April 2011). Ramekins filled with condiments like nuts and seeds (GI=0).  Nuts and seeds provide healthy fats, fiber, vitamins, minerals, and antioxidants, while they slow digestion and curb blood sugar. Sourdough bread or whole-grain bread with whole kernels; butter from grass-fed cows and organic nut and seed butters such as tahini and pumpkin seed butter. A pitcher of water and glasses for all—sometimes we mistake hunger for what is in fact thirst.  You might flavor the water with a little lemon juice or other flavoring. Because 12-hour fasting, pre-meal blood sugar reading can vary, all data points at time zero prior to the first morning meal were indexed to zero in order to illustrate the change from a neutral starting point. I use the label “traditional” carbohydrates, just as we call unrefined fats, “traditional” fats. In general, it is recommended that any blood test that is outside the normal range be repeated on a different day to confirm the diagnosis. Identify your HbA1c test score, mean blood and glucose level to know if your blood glucose is in the optimum level. Americans must start living a healthier lifestyle, including eating better diets and getting more exercise.


David Brownstein has spent decades researching solutions to this high blood sugar epidemic, one he feels is now our country’s #1 health crisis. And if your levels were high but still in the clinically normal range, your doctor may not have told you about the potential health concerns.
Another potential problem you should know about is that elevated blood sugar becomes much more common as you grow older. Learn the 7 Signs That Your Blood Sugar Is Out of Control.
The second factor—the postwar shift from traditional to refined carbohydrates—is largely due to the growing role of the commercial food industry and processed, convenience foods.  Convenience foods must have a long shelf-life, so food companies rely upon refined flours and oils, which do not go rancid.
Visual pictures of postprandial blood sugar behavior, while less scientific than GI measurements, are nevertheless powerful learning tools, providing a real flavor for how our body reacts when we eat different kinds of foods.
This chart illustrates the second meal effect– that what we eat at one meal affects postprandial blood sugar behavior at the next. What we do to our children when we give them a sugary cereal or a Pop-tart for breakfast extends beyond this first meal to affect their blood sugar, hunger, concentration, and desire to overeat throughout the rest of the day. One of the best herbs and spices to moderate blood sugar.  It can be sprinkled on hot cereals and desserts such as puddings, custards, and stewed fruits. The American Diabetes Association recommends the FPG because it is easier, faster, and less expensive to perform. Sanjay Gupta investigate this issue and interview some of America’s most respected scientists. This is why diabetes and obesity often go hand-in-hand (90% of diabetics are either overweight or obese).
