If you usually skip a morning meal because you don’t have time, a nutritious breakfast cereal can be a quick and easy way to tát start your day. 

This article will explain how breakfast affects blood sugar levels and why you should choose cereals with a low glycemic index rating if you have diabetes. It also will help you learn about the common sweeteners that hide in popular cereals as well as some tips on choosing diabetes-friendly breakfast cereals.

How Breakfast Helps Blood Sugar

Research has shown that starting the day with a higher-fat, higher-protein, lower-carbohydrate breakfast can help stabilize your blood sugar levels and help you manage your weight if you have diabetes. Protein and fat help fill you up, which means you're likely to tát eat fewer calories throughout the day.

High blood sugar in the morning is common among people with diabetes. Blood sugar levels can also rise after breakfast, which can cause “a vicious cycle": High blood sugar can make you crave more carbohydrates, and eating more calories and carbs can cause your blood sugar to tát go up.

Choosing Cereal With a Low GI

If you have diabetes, choose foods with a low glycemic index (GI) rating. This number measures how fast the carbohydrates in a food will raise your blood sugar levels. The lower the GI index number, the longer the food takes to tát digest and get absorbed into your blood. When food takes longer to tát digest, you will be less likely to tát see a big and fast increase in your blood sugar.

Looking for a breakfast cereal with the lowest GI rating can help keep your blood sugar levels steady. Keep these numbers in mind:

  • Low-glycemic foods are rated 55 or less.
  • Medium-glycemic foods are rated between 56 and 69.
  • High-glycemic foods are rated from 70 to tát 100.

Simple vs. Complex Carbs

Carbohydrates are also often classified as "simple" or "complex." The glycemic index was created as a better way to tát categorize carbohydrates, especially in terms of how they affect blood sugar.

Where Do I Find the GI?

If you’re at a grocery store in nước Australia or New Zealand, you’d see the GI index of a breakfast cereal right on the box. These countries encourage food manufacturers to tát put this information on food labels but other countries—including the United States and Canada—do not.

Research by Health Canada published in an American scientific journal found that consumers could be misled if glycemic index values were put on food labels in the U.S. The researchers said that not only are foods with low GI numbers necessarily nutritious but that the numbers could vary depending on the lab conducting the testing.

You can look for and often find GI index ratings using the "International tables of glycemic index and glycemic load values 2021" published by the American Journal of Clinical Nutrition. This index lists about 4,000 food items—about 60% more than thở the index published back in 2008.

Can Cereal Be Healthy?

Some breakfast cereals are more nutritious than thở others. There are many processed cereals on the market that are full of extra calories, carbohydrates, and added sugar—none of which are helpful for people with diabetes.

To make sure you’re meeting your nutrition goals, go for whole-grain cereals that have no more than thở 6 grams of sugar and at least 3 grams of fiber per serving. Whole-grain cereals tend to tát have more fiber and often contain high-protein ingredients lượt thích nuts. Whole grains have also been shown to tát reduce the risk of heart disease, which is common in people with diabetes.

If you have diabetes, a good time to tát eat cereal is before you exercise. Physical activity helps to tát burn sugar (glucose).
