Why Everyone Should Monitor Their Blood Sugar

Why Everyone Should Monitor Their Blood Sugar

Spikes in your blood sugar levels can be damaging, even if you don’t have diabetes.

Glucose spikes, even in folks without prediabetes or diabetes, can be threatening. A new study in PLOS Biology found that healthy people without prediabetes or diabetes (measured by standard tests like HbA1c) are very likely to experience heart- and brain-damaging glucose spikes after eating certain meals. In fact, 80 percent of the study participants who had a breakfast of corn flakes and milk got spiked—their blood sugar reached 140mg/dL, a sign of prediabetes.

What’s going on? The Stanford University researchers say that frequently seeing blood sugar levels in the prediabetic and diabetic range in “healthy” folks may be a sign that the current testing for prediabetes is not sensitive enough. They used continuous glucose monitors, not finger pricks or blood draws, to get their readings.

We say, it’s confirmation that highly processed carbs and high-glycemic-index foods aren’t good for anyone.

Tip: If you get sluggish or out-of-sorts after eating, chances are you’ve chowed down glucose-spiking foods. Now they’re damaging your cardiovascular system, not to mention your gums, guts and good looks. But you can drive a spike through the heart of this unholy trend! Eat only 100 percent whole grains, lots of colorful produce, lean proteins and no added sugars.
