My blood sugar spikes after a small breakfast (1/2 cup bran cereal, 1/2 banana and skim milk). Why?


Q: My blood sugar numbers go from 130 before to 200+ after eating a very small breakfast (1/2 cup bran cereal, 1/2 banana and skim milk). Not so after other meals. Why?

Although your breakfast is small in size, it contains about 45 grams of net carbohydrates. With the exception of fiber, all carbohydrates are broken down into sugar by your body and absorbed into the bloodstream, where they raise blood sugar. In addition, because your meal contains virtually no fat, these carbs will be absorbed very quickly into your blood.

Elevated blood sugar triggers your pancreas to produce insulin to move sugar out of the blood and into your cells. However, people with type 2 diabetes are often insulin resistant, meaning their cells don't respond to insulin's action as well as they should. What's more, many people with diabetes find that they are more insulin resistant in the morning than at other times of the day.

To help keep your blood sugar from rising so high in the morning, eat a meal higher in protein and healthy fat with few carbohydrates. A few options would be a vegetable omelet, cottage cheese with chopped nuts and a small serving of berries, or a protein smoothie that includes avocado or nut butter.
