How to Read Food Labels for Diabetes and Blood Sugar Control

If you are managing diabetes, prediabetes, or insulin resistance, learning how to read food labels is one of the most practical skills you can develop.


Packaged foods often contain hidden sugars and higher sodium levels that can affect blood sugar and long term heart health. The front of the package rarely tells the full story.


At MFM Health, just north of Boston, our endocrinology and nutrition teams help patients across the North Shore interpret food labels in ways that support steady glucose patterns.

Erica Ouellette, RD, CDCES works with patients every day on turning label reading into confident, everyday decisions. By knowing what to look for, you can reduce blood sugar spikes and make more confident food choices in under a minute.



Step 1: Look at Added Sugars

When reading food labels for diabetes, begin with the Nutrition Facts panel. Under Total Carbohydrate, you will see Added Sugars listed in grams. This reflects sugar added during processing. The sugar number is already included in the total carbohydrate number you do not need to re-count. 


Added sugars appear in more places than most people expect:

  • Bread

  • Pasta sauce

  • Breakfast cereals

  • Flavored yogurt

  • Granola bars

  • Canned fruit

  • Juice


Also review the ingredient list. Ingredients are listed by weight. If sugar, syrup, or concentrate appears among the first few ingredients, the product likely contains a significant amount.


Common names include:

  • Sugar

  • Brown sugar

  • Cane sugar

  • Corn syrup

  • Honey

  • Maltose

  • Fruit juice concentrate


Reducing added sugars can help limit rapid blood sugar spikes and support overall diabetes management.



Step 2: Check Sodium

Sodium does not directly raise blood sugar, but it matters in diabetes care.


People living with diabetes are at higher risk for high blood pressure and cardiovascular disease. Many processed foods contain significant sodium to preserve freshness.


High sodium items often include:

  • Canned vegetables

  • Soups

  • Pasta sauces

  • Frozen meals

  • Packaged snacks


Comparing brands can make a meaningful difference. Look for labels such as no salt added, low sodium, or reduced sodium.



Step 3: Review Total Carbohydrates, Fiber, and Protein

Beyond added sugars, also check:

  • Total carbohydrates

  • Fiber

  • Protein


Fiber and protein slow digestion and may reduce sharp glucose rises. Many patients benefit from choosing foods with at least 3 grams of fiber per serving.


If you are working on building balanced meals using these principles, our article on meal prep for diabetes offers a simple framework.


For general educational guidance, the American Diabetes Association provides additional information on carbohydrate monitoring.



Diabetes Education Just North of Boston

If food labels feel confusing or your blood sugar remains difficult to manage, personalized diabetes education can make it clearer.


MFM Health offers coordinated Endocrinology, Diabetes Care, and Nutrition Services on the North Shore of Massachusetts. For many patients who prefer specialty care outside of Boston, having advanced diabetes support closer to home makes follow up easier.


Our team serves communities including Danvers, Peabody, Beverly, Salem, Gloucester, and surrounding towns north of Boston. Learn more about our Diabetes Care services or request an appointment with our Nutrition team.


Diabetes management should feel structured and supported, not overwhelming.
