Protein Bars for Diabetics: frequently asked questions
What makes a protein bar a good fit for people with diabetes?
Look at total carbohydrates, fiber and added sugars, not just protein. Bars with more protein and fiber and fewer refined carbohydrates generally cause a smaller blood sugar rise. Your own glucose response is the best guide, so talk with your care team.
Do protein bars raise blood sugar?
Most do to some degree, because nearly all contain some carbohydrate. How much depends on the carbs, sugars, fiber, protein and fat in the bar, and on what else you eat. Checking your glucose after trying a new bar is the most reliable way to know.
Do sugar alcohols affect blood sugar?
Most sugar alcohols raise blood sugar less than sugar does, but they are not all equal. Erythritol has little effect, while maltitol raises blood sugar more. Large amounts can also cause digestive upset.
Are net carbs the same as total carbs?
No. "Net carbs" usually means total carbohydrates minus fiber and sometimes sugar alcohols. The FDA does not define the term, so brands calculate it differently. If you count carbs for insulin dosing, ask your care team which number to use.
