Diabetes is a medical condition that develops when your body cannot regulate the level of glucose (sugar) in the blood. As a result, your blood glucose (blood sugar) levels become higher than normal. When blood glucose climbs too high, this affects the cells and tissues of your body. As a result, you can have uncomfortable symptoms—such as fatigue, blurry vision or extreme thirst. But that’s not all. Over time, unstable blood glucose can lead to serious and harmful complications. What Causes Glucose Levels 4 Glucose and insulin flow throughout the to Become Elevated bloodstream to all the parts of the body. 5 Insulin attaches to cells throughout the body, 1 Glucose is made by the liver. which open “channels” that allow glucose to move from the bloodstream into the cells. 2 Glucose is also made in the gut by the breakdown of carbohydrates from food and drinks. 6 The cells in the body use glucose for energy. 3 In response to glucose, the pancreas makes 7 Without a trigger by insulin, the channels remain and releases insulin. closed, and glucose is unable to enter the cells. 8 This causes glucose levels in the body to become elevated. 8 7 6 1 2 3 4 5 2 Types of Diabetes This is the most common type of diabetes. It can often be managed with healthy eating, exercise and Type 1 diabetes prescription medicine (pills). Some people may also need insulin injections to manage the disease. Type 1 diabetes occurs when the immune system mistakenly attacks the pancreas, damaging it so that it can no longer make insulin. Without any Prediabetes insulin, the glucose level in the body becomes Prediabetes occurs when blood glucose levels elevated.

There is no standard meal plan or eating pattern that works for all people with diabetes. Work with your healthcare providers to learn what to eat, how much to eat and when to eat. This will help you manage your blood glucose levels and your weight. It may also help lower your risk of heart disease and other diabetes complications.

Divide your food groups on a 9- to 10-inch plate as shown in the diagram. A common goal for meals may include two to four servings of carbohydrates. More detailed guides to help you choose the correct amount and type of foods to eat are on pages 7-9 and pages 42-51. General Guidelines: • A portion of whole grains, whole grain products (breads and cereals), lentils, dried beans, or starchy vegetables fits on one quarter of the plate. Breakfast • A portion of lean protein fits on one-quarter of the plate. • A variety of colorful, non-starchy vegetables fits on half the plate.
