What is a normal fasting blood sugar level? In other words,
what should your blood sugar level be in the morning? And
when does your fasting blood sugar level indicate diabetes, pre-
diabetes or
metabolic syndrome?

Blood sugar levels vary depending upon how much you eat. In
a normal person, blood sugar is regulated by the body's
production of insulin, which is the hormone that activates the
furnace inside each of our cells to start converting sugar into
energy.

Twelve hours typically pass between the last meal of the day
and breakfast. During the four hours after dinner and the eight
hours when you are sleeping, the body is fasting.  

You break the fast when you eat your first meal of the day,
breakfast, meaning "break the fast". At that moment before
breakfast, your blood sugar levels should be the lowest of the
day.  This is when you measure your fasting blood sugar level.

The Magic Number is 100

Normal fasting blood sugar levels are below 100.  The normal
range is between 70 to 100 mg/L (milligrams per decaliter).  In
Europe, the measurement is given in milileters and the
corresponding numbers are 3.5 to 5.5 mmol/L.

What If Your Fasting Blood Sugar Is Above 100?

If your fasting blood sugar is between 100 and 125, you have
"prediabetes".  You should be worried. This means the insulin
mechanisms within your body are impaired.  If your fasting
blood sugar level is 100 mg/dL to 125 mg/dL, you have
impaired fasting glucose — commonly known as pre-diabetes.
























The Next Landmark Is 125

If your fasting blood sugar level is above 125, you are
diabetic.  Any reading above 125 should be repeated to confirm
the results.

According to the Journal of Endocrinolgy,  here are the
recommended blood sugar levels.

Before a meal: 90-130 mg/dL

Two hours after a meal(called the postprandial reading): Below
180 mg/dL

When You Should Call Your Doctor

If your blood glucose is less than 40 mg/dl once or is
frequently less than 70 mg/dL.

If your blood glucose is higher than 180 mg/dL for more than
1 week or if you have two consecutive readings above 300
mg/dL.

Note: The above are the recommendations from the Journal of
Endocrinology. Our team of
Registered Nurses  recommends
that you should be even more cautious, and call your doctor if
you have two consecutive readings above 250 mg/dL.

Here is a chart you can bookmark  for easy reference. More

Does What You Eat for Dinner Affect Your
Fasting Blood Sugar Levels?


Research has discovered that diabetics who eat a small dinner
have lower fasting blood sugar levels in the morning.  

A 1998 study from the University of Texas Southwestern
Medical Center. Department of Internal Medicine examined the
morning blood sugar levels of 17 diabetic patients. The patients
were given 3 different types of meal plans. One meal plan
included a 700 calorie breakfast, a 700 calorie lunch and a
1400 calorie dinner. A second meal plan included a 1400 calorie
breakfast, a 1400 calorie lunch and no dinner. A third meal plan
included a 700 calorie breakfast , a 700 calorie lunch and a
gigantic 2800 calorie dinner.

Which dinner produced the worst fasting blood sugar levels?
The worst morning fasting blood sugar levels were from the
meal plan that included the gigantic 2800 calorie dinner. Those
who ate in this pattern saw their blood sugar levels in the
mornings increase from 12.3 mmol/L to 13.6, and increase of
10.5%.

Moreover, what you eat for dinner not only affects your fasting
blood sugar levels, it also affects how high your blood sugar
levels rise right after breakfast.


A 1988 study from the University of Toronto, Department of
Nutritional Sciences, found that what you eat at night affects
your blood sugar levels in the morning after you eat breakfast.
The study found that those who eat a low glycemic dinner had
lower blood sugar levels in the morning.

The study compared the effects on your morning fasting blood
sugar after eating a low-glycemic dinner (red lentils, barley,
green peas, skim milk cheese, and margarine) with your
morning blood sugar level after eating a high glycemic index
meal ( instant potato, whole meal bread, green peas, skim milk
cheese and margarine) .   

The next morning both groups ate identical breakfasts
consisting of cornflakes and milk.  

The results  were astonishing. Those who ate the low-glycemic
dinner had morning fasting blood sugar readings between
50%
and 90% lower than the group that ate the high-carb dinner.  

Interestingly, only the total glycemic level of the dinner meal
mattered, no whether the meal had fiber or not. In other
words, if you compare 2 dinner  meals of equal glycemic index
numbers, one with higher fiber than the other, both produced
the same morning glucose readings.

The bottom line? What can you do to lower your morning
blood sugar levels? Eat a low-glycemic dinner to improve your
morning blood sugar readings. And, as for the overall calorie
count of your dinner, the best approach is to eat a small dinner
to lower your fasting blood sugar levels in the morning. (Read
more about which
dinner is best for diabetics.)

Or, as the famous nutritionist Adelle Davis said, to achieve
optimal health, "eat breakfast like a king, lunch like a prince and
dinner like a pauper".
