Managing Diabetes: How Food Affects Blood Sugar

Resources for Seniors

If you have diabetes, you need to know how the foods you eat affect your blood sugar levels. It’s not only the type of food you eat but also how much you eat and the combinations of food types you eat. Here are some tips from the Mayo Clinic:

  • Learn about carbohydrate counting and portion sizes. A key to many diabetes management plans is learning how to count carbohydrates. Carbohydrates are the foods that often have the biggest impact on your blood sugar levels. And for people taking mealtime insulin, it’s crucial to know the amount of carbohydrates in your food, so you get the proper insulin dose. Learn what portion size is appropriate for each type of food. Simplify your meal planning by writing down portions for the foods you eat often. Use measuring cups or a scale to ensure proper portion size and an accurate carbohydrate count.
  • Make every meal well-balanced. As much as possible, plan for every meal to have a good mix of starches, fruits and vegetables, proteins and fats. It’s especially important to pay attention to the types of carbohydrates you choose. Some carbohydrates, such as fruits, vegetables and whole grains, are better for you than are others. These foods are low in carbohydrates and contain fiber that helps keep your blood sugar levels more stable. Talk to your doctor, nurse or dietitian about the best food choices and the appropriate balance of food types.
  • Coordinate your meals and medications. Too little food in proportion to your diabetes medications — especially insulin — may result in dangerously low blood sugar (hypoglycemia). Too much food may cause your blood sugar level to climb too high (hyperglycemia). Talk to your diabetes health care team about how to best coordinate meal and medication schedules.
  • Avoid sugar-sweetened beverages. Sugar-sweetened beverages — including those sweetened with high fructose corn syrup or sucrose — tend to be high in calories and offer little in the way of nutrition. And because they cause blood sugar to rise quickly, it’s best to avoid these types of drinks if you have diabetes. The exception is if you are experiencing a low blood sugar level. Sugar-sweetened beverages, such as soda, juice and sports drinks, can be used as an effective treatment for quickly raising blood sugar that is too low.
