A NOVEL WAY TO PREVENT DIABETES

For the serious-minded diabetic, and non-diabetic, here is a simple system I, a diabetic, used to identify foods that I thought were safe, but for me, spiked my glucose. Many people with diabetes eat what they think is safe, only to see their blood sugar climb later. If you’ve found this to be the case, then here is a system that is very simple, practical, and patient-led and it can teach you more in two weeks than a long list of generic rules.

Bottom line: check your blood glucose two hours after meals. If it is over 180 mg/dL, flag the meal. Over time you will build your own list of “safe” and “caution” foods.

Why two hours?

Many foods peak your blood sugar about two hours after you start eating. A quick check at that point gives you a snapshot of how the meal affected you. Think of it like reading the scoreboard after the inning.

What you need: A glucose meter–a smart phone (or timer)–notebook (or notes app)

The step-by-step plan:

Eat your normal meal. No need to change anything yet.

Start a timer. Two hours from the first bite.
