How Do Carbs Affect Blood Sugar?

Insulin resistance is the precursor to Pre-diabetes and Type 2 diabetes. As weight increases, cells become more resistant to the insulin that the pancrease produces. This leads to increased glucose circulating in the blood

Question: How Do Carbs Affect Blood Sugar?

When you eat carbohydrates, either simple or complex, your body breaks them down into sugars, which are absorbed into the bloodstream. The sugar level rises, and in response, your pancreas releases a hormone called insulin. Insulin helps take the sugar from the blood and put it into the cells, where it can be used as energy to fuel your body.

Some carbohydrates affect blood sugar more than others. Processed grains like white flour and white rice raise blood sugar more quickly than whole wheat or brown rice. Refining a grain strips it of nutrients and fiber and makes it easier to digest, whereas fiber helps slow down digestion so that sugar is released more slowly into your blood. Eating fiber is helpful, since it keeps your blood sugar from spiking.
