"Although Stevia is considered safe for people with Diabetes, brands that contain Dextrose or Maltodextrin should be treated with caution. Dextrose is Glucose, and Maltodextrin is a starch. These ingredients add small amounts of Carbs and Calories. Sugar alcohols may also slightly tip the Carb count." www.healthline.com
When shopping always carry a small magnifier. There are even credit card size ones. Don't trust what you first see on any product main label. "No sugar added" is another one - no sugar added but the Nutrition labeling will reveal how much is really there. Pay attention to the CARBS in the nutrition list. First thing I look for is total Carbs as sugar is a Carb. Quite often "No sugar added" has a higher Carb count - not always, so beware.
I just checked an old box of "Sugar Twin" that has a big label on the front saying "Sucralose", but ingredient list shows Dextrose as #1 ingredient and nutrition list shows "0" Carbs and "0" Sugar - can't have it both ways. Very misleading.
Dextrose is the name of a simple sugar that is made from corn and is chemically identical to glucose, or blood sugar.
If it states "Sugar Free", again, check for the Carbs.
The Stevia I rarely use has a total of one (1) Carb per packet and zero sugar (no dextrose, fructose, etc.), but does have a bit of Erythritol.
SWERVE is another sugar replacement. 1 teaspoon is 4 Carbs. Says "a unique blend of non-GMO ingredients that are derived from fruits and vegetables" and has Erythritol.
The only time you could probably get action on misleading labels is if it states "For Diabetics" or "good for Diabetics" then it is making a medical claim. Otherwise it is up to you to be cautious and double check anything you buy.
Can we trust all manufacturers to be totally truthful in labeling and ingredients list? No - simple answer. It is your health, your life, so do a lot of due diligence when shopping for food or ingredients. If in doubt - don't get it.
