Food Labels and Diabetes: Expert Q&A

What about carbohydrates?

There’s a lot of debate about the healthiest ratio of carbohydrates, fat, and protein. I think a good rule of thumb is about 40% of the calories should come from carbohydrates, about 30% from fat, and around 30% from protein. Protein helps make meals more satiating, and that can help people lose weight or maintain a healthy weight. Protein also helps in maintaining the lean muscle mass during weight loss and does not raise the blood glucose levels as carbohydrates do.  You still need at least 130 grams of carbohydrates or more per day. Both the total amount of carbohydrates and their type matter. As I said, it’s especially important that the carbohydrates you consume are as unrefined as possible.

How can food labels help?

First, look at the ingredient list on the food label to see that it contains whole wheat, whole oats, and other unrefined grains. The 2010 Dietary Guidelines recommend three servings of whole-grain foods a day. (A serving equals 16 grams of whole grains.) The Whole Grain Stamp that appears on many labels can be helpful. It indicates that a food contains at least 8 grams of whole grains per serving. A food that bears the label “100% Whole Grains” contains at least 16 grams. I usually tell my patients when you select your carbohydrates, try to remember VFW (vegetables, fruits and whole grains) and make your selection from them.

Other logos are appearing on foods to show that they meet certain health guidelines, such as the American Heart Association’s heart check. Are they also useful?

They offer a helpful shorthand evaluation. But I think consumers should still be careful to look at the nutrient facts panel and the ingredients on their own. For example, when you see "sugar free", it does not mean it is carbohydrate free. You still need to see how much carbohydrates and what type of carbohydrates.  The American Heart Association checkmark evaluates saturated fat and sodium, for example, but it doesn’t consider how much sugar a food contains. And, of course, too much sugar in the diet can increase the risk of diabetes.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
