People with type 2 diabetes can manage their blood sugar levels by following a diet that is rich in nutrient-dense foods, including fibre, vitamins, and minerals. There is no one-size-fits-all diet for managing type 2 diabetes, but there are some general guidelines to follow. Firstly, it is important to limit or avoid foods that cause blood sugar fluctuations, such as sugary foods and refined carbohydrates. Instead, opt for whole grains, dairy, and high-fibre foods like beans, lentils, and pulses. It is also beneficial to include healthy fats, such as monounsaturated and polyunsaturated fats, to lower cholesterol and protect heart health. Counting carbohydrates and using portion control methods, such as the Diabetes Plate, can also help manage blood sugar levels. Consulting with a healthcare professional or a registered dietitian is recommended to create a personalised meal plan that considers individual needs, tastes, and lifestyles.
Characteristics of a Type 2 Diabetic Diet:
| Characteristics | Values |
|---|---|
| Carbohydrates | Limit or avoid bleached and refined carbohydrates such as white bread, white pasta, and white rice. Choose whole grains instead. |
| Proteins | Include good sources of protein such as beans, lentils, pulses, lean meats, and dairy products. |
| Fats | Focus on adding healthy fats like monounsaturated and polyunsaturated fats found in olive oil, nuts, avocados, and some types of fish. |
| Fruits | Fruits are recommended, especially those with a low glycemic load, as the sugar in whole fruit does not count towards free sugars. |
| Vegetables | Include more non-starchy vegetables like broccoli, spinach, green beans, and salad greens. |
| Sodium and Caffeine | If managing hypertension along with diabetes, reduce sodium and caffeine intake. |
| Gluten | For those with celiac disease and type 2 diabetes, ensure food is gluten-free. |
| Alcohol | Drink in moderation, with a limit of one standard drink per day for women and two for men. |
| Meal Planning | Work with a healthcare professional to design a meal plan that considers your goals, tastes, lifestyle, and medications. |
| Portion Control | Use methods like the Diabetes Plate or the Plate Method to guide portion sizes and balance your meal components. |
| Home Cooking | Cooking at home allows for better control over added sugars and portion sizes. |

What You'll Learn
Limit carbs and sugary foods
People with type 2 diabetes should limit their consumption of carbohydrates and sugary foods. This is because carbohydrates break down into glucose (a type of sugar) in the body, which raises blood sugar levels. Limiting carbohydrates and sugary foods can help manage blood sugar levels and may even reduce the need for diabetes medication.
When it comes to carbohydrates, it is important to choose nutrient-dense options that are rich in fibre, vitamins, and minerals while being low in added sugars, sodium, and unhealthy fats. Whole grains, such as whole wheat bread, brown rice, and whole grain pasta, are excellent choices. They leave you feeling fuller for longer and can be more flavourful than refined carbohydrates.
It is recommended to limit or avoid refined and highly processed carbohydrates, such as white bread, white pasta, and sugary cereals. These foods can cause blood sugar spikes and fluctuations, which are detrimental to diabetes management. Instead, opt for complex carbohydrates with a low glycemic load, such as beans, lentils, and other pulses, which provide a good source of dietary fibre and protein.
Sugary foods and drinks, such as soda, sweet tea, juice, cakes, cookies, and candy, should also be limited or avoided. These foods contain high amounts of added sugars, which can cause a rapid increase in blood sugar levels. Instead, satisfy your sweet tooth with fresh fruit, as the sugar in whole fruit does not count towards free sugars and has a low glycemic load.
Additionally, when it comes to dairy products, choose low-fat or fat-free options, as full-fat dairy is high in saturated fat. However, be cautious of fat-free products that have replaced fat with sugar, as this can also negatively impact blood sugar levels.

Eat whole grains, fruit and vegetables
People with type 2 diabetes don't need to give up grains, fruit, and vegetables entirely. However, it is essential to make careful choices and consume these foods in appropriate quantities.
Whole grains
Whole grains are packed with fibre, which can help lower cholesterol and reduce the risk of heart disease. Fibre also slows digestion and the absorption of carbohydrates, preventing blood sugar spikes. Examples of whole grains include whole wheat, oats, amaranth, buckwheat, quinoa, and popcorn. When baking bread, muffins, pancakes, or waffles, use half whole wheat flour and half other whole-grain flour. Look for "whole grain" as the first ingredient on food labels, and be mindful of portion sizes, typically around three servings per day.
Fruits
Fruits contain carbohydrates, so they should be counted as part of your meal plan. Opt for fresh, frozen, or canned fruits without added sugars. Look for phrases like "packed in its own juices," "unsweetened," or "no added sugar." Dried fruit and 100% fruit juice are nutritious but have smaller portion sizes and may not be as filling. A small piece of whole fruit or 1/2 cup of frozen or canned fruit typically contains about 15 grams of carbohydrates.
Vegetables
Non-starchy vegetables are an excellent choice for people with type 2 diabetes. They are packed with vitamins, minerals, fibre, and phytochemicals, yet they have very few calories and carbohydrates. Enjoy a variety of fresh, frozen, or canned vegetables without added sodium, fat, or sugar. Rinse canned vegetables to reduce sodium content. Aim for at least six servings of vegetables per day.

Choose lean proteins
People with type 2 diabetes should follow a diet that is rich in lean proteins, fruits, vegetables, and high-fibre carbohydrates. Lean proteins are important for people with diabetes as they are slow to digest and cause only mild increases in blood sugar.
When choosing lean proteins, opt for lean meats, fish, dairy, and plant-based foods. Lean meats include trimmed cuts of beef such as chuck, rib, rump roast, round, sirloin, cubed, flank, porterhouse, T-bone steak, or tenderloin. Lean poultry like chicken or turkey breast without skin is also a good option as it is low in saturated fat and beneficial for heart health. A 3-ounce portion of baked salmon provides around 17 grams of protein and is a good source of heart-healthy omega-3 fatty acids.
If you are concerned about cholesterol, choose egg whites or cholesterol-free egg products. Eggs are another excellent source of protein, with one large egg providing 6 grams. Low- or non-fat Greek yogurt (5.5 ounces) offers 16 grams of protein, but be sure to choose the plain variety to avoid added sugars.
For plant-based proteins, try beans, lentils, tofu, and edamame. These are great sources of dietary fibre and protein. The high fibre content in these foods means that the digestive tract absorbs fewer carbohydrates, making them excellent carbohydrate choices for individuals with diabetes. They can also be used as a replacement for meat or cheese in meals.
In addition to choosing lean proteins, it is important to maintain a balance of carbohydrates and healthy fats. Whole grains, such as brown rice, whole wheat bread, and whole grain pasta, are preferable to refined carbohydrates like white bread and pasta.

Consume healthy fats
Consuming healthy fats is an essential part of managing type 2 diabetes. While it is important to limit the consumption of saturated fats, replacing them with unsaturated fats can help lower the chances of developing type 2 diabetes. These unsaturated fats, which include monounsaturated and polyunsaturated fats, are known to lower blood sugar levels and improve insulin control. They can also help lower cholesterol levels and protect your heart.
Healthy fats are found in a variety of foods, such as olive oil, nuts, avocados, and certain types of fish. Nuts, in particular, are a great source of polyunsaturated and monounsaturated fats and have been linked to a lower risk of diabetes in women. Other sources of healthy fats include walnuts, sunflower seeds, soybeans, flaxseed, and other vegetable oils and spreads. These fat-rich foods can be consumed instead of refined grains, starches, sugars, and animal fats.
It is important to note that while fats are essential, they should be consumed in moderation as part of a balanced diet. The specific amount of fat that can be consumed daily may vary depending on age, sex, daily activity level, and other factors. For example, the recommended daily calorie limit for males over 40 is about 2,200 calories, while for females over 40, it is approximately 1,800 calories.
In addition to consuming healthy fats, individuals with type 2 diabetes should also focus on including other nutrient-dense foods in their diet. This includes whole grains, lean proteins, high-fiber carbohydrates, and fruits and vegetables. Beans, lentils, and other pulses are excellent sources of dietary fiber and protein, and they can help manage blood sugar levels by slowing the absorption of carbohydrates.
By incorporating healthy fats and making informed food choices, individuals with type 2 diabetes can effectively manage their blood glucose levels and overall health.

Stay hydrated
Staying hydrated is important for everyone, but it is especially crucial for people with type 2 diabetes. Here are some tips to ensure adequate hydration:
Drink Plenty of Water: Water is essential for maintaining the body's fluid balance and regulating body temperature. It is crucial to drink enough water throughout the day to stay hydrated. Aim for 6-8 cups of water or more, depending on your activity level and environmental conditions.
Limit Caffeinated and Sugary Drinks: Caffeinated beverages, such as coffee and tea, can have a diuretic effect, causing increased urination and potential dehydration. It is best to limit their intake and opt for herbal teas or decaffeinated options. Similarly, sugary drinks, including sodas and fruit juices, can cause blood sugar spikes and provide empty calories. Choose water or infused water instead to stay hydrated and maintain blood sugar control.
Include Water-Rich Foods: Incorporating water-rich foods into your diet is another way to stay hydrated. Fruits and vegetables like watermelon, cucumbers, strawberries, oranges, and celery are excellent sources of hydration and also provide essential nutrients. They can help you stay hydrated and contribute to your overall fluid intake.
Be Mindful During Exercise: Physical activity is essential for managing type 2 diabetes, but it is crucial to stay properly hydrated before, during, and after your workouts. Drink water regularly throughout your exercise routine and pay attention to your body's thirst cues. Additionally, check your blood glucose levels before and after physical activity, as exercise can lower blood glucose levels for hours or even days afterward.
Monitor Fluid Intake with Sodium: While staying hydrated is crucial, it is also important to be mindful of your sodium intake. Excess sodium can lead to water retention and impact hydration levels. Aim for a balanced approach by limiting processed foods and added salts while ensuring you're adequately hydrated.
By following these guidelines, individuals with type 2 diabetes can ensure they stay properly hydrated, which is vital for overall health and diabetes management.
