What to Know

Medication, regular exercise, and healthful eating habits are the cornerstones of diabetes control. Nothing will take their place.

Research suggests that vinegar may reduce blood glucose in people with type 1 or type 2 diabetes. But the American Diabetes Association says evidence is insufficient to recommend its use and advises caution.

If vinegar does have an effect, researchers suspect that it may work by slowing the digestion of starches, delaying the emptying of food from the stomach (which may also reduce appetite and aid weight loss), altering glucose production in the liver, and through other unknown mechanisms.

Before changing your diet, supplements, or any lifestyle factors, discuss your plans with your health care provider. A single change may require additional alterations to your medications or other aspects of your treatment plan. Also, more frequently checking your blood glucose can help you learn quite a bit about the effect various foods have on your blood glucose. To estimate this, do a finger-stick blood glucose test before eating and approximately two hours after your first bite.


Nothing will replace a nutritious eating plan and healthful living. If you need changes in these areas, ask for a referral to a registered dietitian who is also a diabetes educator. This is the person who will help tailor a plan to fit your needs.
