A diabetic diet is a diet that is used by people with diabetes mellitus or high blood glucose to minimize symptoms and dangerous consequences of the disease. Since carbohydrate is the macronutrient that raises blood glucose levels most significantly, the greatest debate is how low in carbohydrates the diet should be. Food has a direct effect on blood glucose. Some foods raise blood glucose more than others.
An important part of managing diabetes is knowing what and how much to eat, and following an eating plan that fits your lifestyle while helping to control blood glucose. The 3 main nutrients found in foods are carbohydrates (carbs), proteins and fats.
Carbs are the starches, sugar, and fiber in foods such as grains, fruits, vegetables, milk products, and sweets. They raise blood glucose faster and higher than other nutrients in foods: proteins and fats. Knowing what foods contain carbs and the amount of carbs in a meal is helpful for blood glucose control. Choosing carbs from healthy sources like vegetables, fruits and whole grains (high fiber) are preferred over carbs from sources with added sugars, fat, and salt.
Proteins are a necessary part of a balanced diet and can keep you from feeling hungry. They do not directly raise your glucose like carbs. However, to prevent weight gain, use portion control with proteins. In people with Type 2 diabetes, protein makes insulin work faster, so it may not be a good idea to treat low blood sugar with protein shakes or mixes. Using 15 grams of fast-acting carbs that contain glucose like juice, other sugar-sweetened beverages, glucose gel or tablets is the preferred way to treat low blood sugar.
Fats are a necessary part of a balanced diet, especially healthy fats from fatty fish, nuts, and seeds. They do not raise blood glucose but are high in calories and can cause weight gain.
Aim to include all 3 nutrients to balance your meals.
1. Making healthy food choices
Your dietitian or diabetes educator can help you develop an eating plan that is right for you and fits into your lifestyle.
2. Here are some guidelines for healthy eating:
- Healthy eating for diabetes is healthy eating for the whole family.
- Enjoy having regular meals with proper portion sizes. Your healthcare professional can help you learn to make healthy food choices and proper portion sizes.
- Eat a variety of nutrient-rich foods in each meal, including healthy fats, lean meats or proteins, whole grains and low-fat dairy in appropriate portion sizes.
- Choose fiber-rich foods such as fruits, vegetables and whole grains (bran cereals, whole wheat pasta, brown rice) as often as possible.
- Try alternatives to meat such as lentils, beans or tofu.
- Choose calorie-free liquids such as unsweetened tea, coffee or water.
- Choose sugar substitutes.
- Choose lower salt options.
3. Visualizing food portion size: it’s in your hands
Your choice of food and how much you eat is relative to your blood glucose level. If you eat more than you need, your blood glucose will rise. To help manage your diabetes, having a good sense of portion control is an important skill. Luckily, you already have some tools – your hands.
4. Healthy food shopping
Before you shop:
- Plan your meals for a duration of time (e.g. several days to a week) and include a variety of foods from the food groups.
- Create a grocery list from your meal plan.
5. At the grocery store:
- Bring your list and stick with it.
- Never shop hungry, since this often leads to impulse choices of less healthy foods.
- Shop the perimeter (the outer edges) of the store, such as the produce section where the “real food” versus the preserved food is.
- Avoid sugary drinks, sweets, and chips.
- Check food labels to help you make healthy choices.
