Type 2 Diabetes and Food Choices
You make food choices every day. Whole wheat or white bread? A side of french fries
or fresh fruit? Eat now or later? Choices about what, when, and how much you eat affect
your blood glucose. Understanding how food affects blood glucose is the first step
in managing diabetes. According to the American Diabetes Association, following a
diabetes meal plan can help you keep your blood glucose levels on track.
Having type 2 diabetes means that your body doesn’t control blood glucose well. When
blood glucose stays too high for too long, serious health problems can develop. By
controlling your blood glucose through diet, exercise, and medicine, you can delay
or prevent kidney, eye, and heart disease, and other complications of diabetes.
Carbohydrates are foods that have the biggest effect on your blood glucose levels.
After you eat carbohydrates, your blood glucose rises. Fruit, sweet foods and drinks,
starchy foods (such as bread, potatoes and rice), and milk and milk products contain
carbohydrates. Although carbohydrates are important for health, when you eat too many
at once, your blood glucose can go too high, especially if you do not have or take
adequate insulin for that food.
Some carbohydrates—potatoes, sweets and white bread, for instance—may raise blood
glucose more than others. Better choices are less processed foods with more fiber
and nutrients, such as 100% whole wheat bread, oatmeal, brown rice, and nonstarchy
Learn to use food labels that indicate added sugar and try to find healthier alternatives,
particularly if you are overweight.
Food and medicine
Insulin helps glucose move from the blood into your muscle cells, where it can be
used for energy. Some oral diabetes medicines help you make more insulin or help your
insulin work more efficiently, so your medicines and food plan have to work together.
If you take insulin shots, you need to be especially careful to match the amount of
carbohydrates you eat with your insulin dose. If you consume too many carbohydrates
without adjusting your insulin dose, your blood glucose might become too high. If
you consume too few carbohydrates, your blood glucose might be too low. Your healthcare
provider or a dietitian can help you match your food choices to your medicine.
Have a meal plan
With certain medicines, it is best to eat the same amount of food at the same time
every day. That keeps your glucose levels stable and helps your medicine work best.
Physical activity is an important way to control blood glucose, too. Try to exercise
at the same time every day. That way you can build the extra calories you need for
exercise into your meal plan. With other medicines, you may have more choices about
how much you eat and when.
If you wish to change the medicine to suit your lifestyle, please discuss with your
healthcare provider, first.
You can eat the same foods as everyone else, but you have to pay attention to certain
details. That’s where your diabetes meal plan comes in. An individualized meal plan
tells you the time of day to eat meals and snacks, the types of food to eat, and how
much. It should include your favorite foods and emphasize these healthy foods:
Whole grains, such as 100% whole wheat bread, brown rice, and oatmeal
Nonfat or low-fat dairy products, such as nonfat milk and yogurt
Lean meats, poultry, fish, eggs, and dried beans and peas
Foods and drinks with no added sugar.
Fruits and vegetables
At first, it may be helpful to use measuring cups and spoons to make sure you’re actually
consuming the amount of food that’s in your plan. By checking your blood glucose 1
to 2 hours after eating, you can learn how your food choices affect your blood glucose.
To develop a diabetes meal plan or change a plan that’s not working for you, see a
dietitian or diabetes educator. Having a meal plan that you can live with will keep
you at your healthy best.
