But for people with diabetes these benefits may outweigh the potential risks of starting the day with a product that's laden with sugar and lacking in nutrients, as many options are. maystarting the day with bowl of Given breakfast is regarded as the most important meal of the day, it can be argued that It's been said countless times breakfast is the most important meal of the day, but for people with di for people with diabetes what the morning meal comprises is as important as whether it takes place at all. .

Lower Carbohydrate, Higher Fat and Protein Breakfast

Studies have shown that starting the day with a higher fat, higher protein, lower carbohydrate breakfast can have a positive effects on blood sugar levels and weight control in patients with diabetes. Protein and fat tend to be more satiating which can keep you feeling full for longer, typically resulting in less overall calorie intake. In addition, blood sugars tend to rise higher after breakfast and many people are resistant to insulin in the morning which can also cause blood sugars to spike. Elevated blood sugars may cause additional carbohydrate cravings, which can lead to excess calorie and carbohydrate intake, often resulting in excess sugar in the blood. 

Can Cereal be Healthy?

When breakfast meal planning, it's important to know some cereals are healthier than others. When choosing a cereal, it's important to choose a cereal that is low in sugar and high in fiber. In specific terms, look for cereals that have six grams of sugar and at least three grams of fiber.

Processed, refined, high sugary cereals are rich in calories, carbohydrates and sugar - none of which is great for diabetes. On the other hand, whole grain cereals made with healthy ingredients such as nuts can be considered healthy. Of note - following a diet rich in whole grains can reduce the risk of heart disease.

If you chose wisely and watch your portions, you can enjoy cereal. In fact, many cereals are fortified with vitamins and minerals, which can help people meet their nutritional needs. For someone with diabetes, a good time to eat cereal can be before exercise. Physical activity helps to burn sugar (or glucose). If you are someone who takes an oral medication or insulin that can cause your blood sugar to drop, you'll likely need to eat carbohydrates before exercise to prevent low blood sugars during physical activity. 

Tips to Lower the Carb Content in Cereal

    • Choose a hot cereal like oatmeal, quinoa or another whole grain blend and add chopped nuts or nut butter for added fiber, protein and healthy fat. For example: 1/2 cup cooked oatmeal with 3/4 cup blueberries, and 2 tablespoons chopped walnuts, topped with cinnamon.
      If you are choosing a cold cereal:
      Read the label and stick to one serving, measure it with a measuring cup and use a small bowl to make the portion appear larger
    • Choose a cereal that is a whole grain (the first ingredient should say whole)
    • Choose a cereal that has at least three grams of fiber and no more than six grams of sugar 
    • Avoid adding dried fruit, sugar, or other calorie sweeteners, such as agave, honey, table sugar 
    • Add one serving of high fiber fruit to increase fiber content such as: blueberries, raspberries, strawberries
    • Choose unsweetened almond milk for less carbohydrate than cow's milk 
    • Skip the milk altogether and make a yogurt parfait: using low-fat Greek yogurt which will boost protein content and reduce carbohydrate content
