Protein Considerations
When managing diabetes, it's important to carefully consider protein sources and portions. Here are some key points to keep in mind.
Limiting Red and Processed Meats
It is advised to limit the intake of red meat, which is often higher in saturated fat. Processed meats like ham, bacon, and hot dogs also tend to be high in both saturated fat and sodium. If consumed, choose the leanest options available. Reducing these types of meat can help manage cholesterol levels and reduce the risk of heart disease, which is particularly important for diabetics.
Dairy and Eggs
Dairy products and eggs can be valuable sources of protein for individuals with diabetes. Options such as cheese, eggs, and lean cuts of beef, pork, veal, and lamb are mentioned as protein choices. These can be included in a balanced diet, but it's important to consider the fat content and choose lower-fat options when possible [1].
Choosing Optimal Protein Portions
For most people with diabetes, the amount of protein needed is similar to that of individuals without diabetes, typically providing 10-35% of total calories. The average protein intake for adults in the U.S. and Canada is about 15% of total calories. This translates to about 6 to 8 ounces of lean meat, poultry, or fish daily, with a 3-ounce portion of protein being roughly the size of a deck of playing cards. Aim to include approximately two of these portions in your daily diet.
By carefully selecting and portioning protein sources, individuals with diabetes can manage their condition more effectively. For more information on related topics, check out our guides on best food for gut health, best food for dementia, and best foods for stroke recovery.
Carbohydrate Management
Managing carbohydrate intake is fundamental for individuals with diabetes. This section explores the role of whole grains and fiber, the impact of carbohydrates on blood glucose, and the importance of carb counting and insulin management.
Whole Grains and Fiber
Whole grains and fiber play a crucial role in managing blood glucose levels. Fiber can be found in wholemeal bread, brown rice, wholegrain cereals, fruits, vegetables, nuts, seeds, pulses, potatoes, oats, and barley. Fiber helps to keep the digestive system healthy and can assist in controlling both blood glucose and cholesterol levels.
Whole grains are particularly beneficial for people with diabetes because they often have a lower glycemic index (GI). This means they cause a slower, more controlled rise in blood glucose levels. It's advisable to avoid bleached and refined carbohydrates, such as white bread and white pasta, and instead choose whole grains like whole grain rice, pasta, or bread [4].
Impact of Carbohydrates on Blood Glucose
Carbohydrates are composed of starches, sugars, and fiber. The goal is to choose carbohydrates that are nutrient-dense, rich in fiber, vitamins, and minerals, and low in added sugars, sodium, and unhealthy fats to effectively manage blood glucose levels [5]. The quality of carbohydrates is more crucial to health than the quantity consumed. Lower GI foods, high fiber content, and whole grains are beneficial for managing blood glucose levels and overall health. Opting for foods high in fiber and whole grains over refined carbs like white bread is also better for heart health and reducing the risk of certain cancers.
Carb Counting and Insulin Management
Carb counting involves calculating the number of grams of carbohydrate in a meal and matching that to a dose of insulin. This method is crucial for individuals with diabetes to manage their blood glucose levels effectively. Knowing the amount of carbohydrates in food is especially important for those taking insulin. Understanding which foods contain carbohydrates, estimating carbohydrate portions, and monitoring their impact on blood glucose levels is essential for diabetes management.

By focusing on whole grains, understanding the impact of carbohydrates on blood glucose, and practicing effective carb counting, individuals with diabetes can better manage their condition and improve their overall health.
Nutrient-Dense Choices
For individuals managing diabetes, selecting nutrient-dense foods is crucial for maintaining stable blood sugar levels and overall health. This section highlights some of the best food options for diabetics, focusing on low-glycemic index foods, fruits and vegetables, and healthy carbohydrate alternatives.
Low-Glycemic Index Foods
Low-glycemic index (GI) foods help to prevent spikes in blood sugar levels. These foods are digested and absorbed more slowly, leading to a gradual rise in blood sugar.
- Stone-ground whole wheat or pumpernickel bread and 100% stone-ground whole wheat bread have low GI scores, making them suitable choices for people with diabetes.
- Millets, including sorghum, have a low GI score and regular consumption has been associated with reduced average fasting blood sugar levels by up to 12% and decreased postmeal blood sugar levels by up to 15% in individuals with T2DM [6].
- Fresh fruits, except for pineapples and melons, generally have low GI scores due to their high water and fiber content [6].
- Sweet potatoes and yams have lower GI scores compared to white potatoes and are nutritious options for individuals with diabetes.
- Legumes, such as beans, peas, chickpeas, and lentils, have very low GI scores and are rich in nutrients that can assist in maintaining healthy blood sugar levels [6].
Fruits and Vegetables
Fruits and vegetables are essential for a balanced diet and provide numerous health benefits for diabetics. They are rich in vitamins, minerals, and fiber, which can aid in blood sugar management.
- Apples and berries are excellent low-GI fruit choices that provide fiber and antioxidants.
- Leafy greens like spinach and kale are nutrient-dense with vitamins A, C, and K.
- Broccoli and carrots offer fiber and essential vitamins while maintaining a low GI.
- Tomatoes are rich in antioxidants and vitamins, making them a healthy choice for diabetics.
Healthy Carbohydrate Alternatives
Finding healthy alternatives to high-GI carbohydrates can help manage diabetes effectively. These alternatives offer nutritional benefits without causing drastic spikes in blood sugar levels.
- Quinoa is a complete protein and high in fiber, making it an excellent alternative to traditional grains.
- Cauliflower rice and zucchini noodles are low-carb substitutes for rice and pasta.
- Chia seeds and flaxseeds provide fiber and omega-3 fatty acids, beneficial for heart health and blood sugar regulation.
