DrMirkin.com, July 31, 2009, by Gabe Mirkin MD       In North America, more than 35 percent of the population

becomes diabetic, and most cases of diabetes could be prevented

with exercise.  A high rise in blood sugar levels causes sugar

to stick on the surface of cells. Once there, the sugar can never

get off and is eventually converted to sorbitol which destroys

the cell to causes all the side effects of diabetes such as

heart attacks, strokes, arteriosclerosis, nerve damage and so

forth (even in people who have not been diagnosed as diabetic).

So anything that prevents frequent high rises in blood sugar

helps to prevent cell damage.

       This month, a study showed that exercise lowered high

blood sugar levels in diabetics far more when done AFTER

eating dinner than before eating (Journal of the American Medical

Directors Association, July 2009).  Muscle contractions drive

sugar into cells with little or no insulin.  These people were

out-of-shape diabetics who walked slowly and for only 20 minutes.

Longer and more intense exercise lowers insulin and sugar levels

even more and would be even more beneficial.

       Another new study shows that you should exercise BEFORE

you eat because it lowers blood sugar levels the next morning

(Medicine and Science in Sports and Exercise, August 2009).

Nine healthy postmenopausal women exercised two hours on a

treadmill twice a day.  Those who exercised an hour before meals

had a much lower rise in blood sugar at 16 hours after eating,

compared to those who exercised an hour after their meals.

       Humans must use their muscles to stay healthy.

Contracting muscles before eating helps to prevent the rise in

blood sugar that follows meals, and exercising after eating helps

to keep blood sugar levels low the next morning.  Of course many

people do not have the time to exercise both before and after

meals, but you will benefit from exercising WHENEVER you can

because lowering blood sugar and blood fats helps to prolong

life and prevent diseases such as diabetes.  www.DrMirkin.com
