Choosing the right protein foods can make eating well with diabetes a little easier. Protein helps maintain muscle, supports your body’s repair processes, and can make meals more satisfying. Many protein-rich foods also have relatively little effect on blood sugar when eaten on their own.
But not every protein source offers the same nutritional benefits. Salmon, chicken, eggs, beans, tofu, and Greek yogurt can all be good choices, although they differ in their carbohydrate content, saturated fat, fiber, and other nutrients.
The good news is that you don’t need expensive supplements or a special high-protein diet to get enough protein.
This guide explains which protein foods are good choices for people with diabetes, how much protein they provide, how to choose appropriate portions, and when your individual protein needs might be different.
What Are the Best Protein Sources for People With Diabetes?
Some of the best protein choices for people with diabetes include fish, skinless poultry, eggs, beans, lentils, tofu, plain Greek yogurt, and cottage cheese.
These foods provide protein along with other nutrients that support overall health. Many are naturally low in carbohydrates, while plant-based options such as beans and lentils provide fiber that can be helpful for blood sugar management.
When choosing protein foods, consider more than the amount of protein they contain. Saturated fat, sodium, fiber, and how the food is prepared also matter.
The following table compares several common protein sources.
| Protein Food | Typical Serving | Approximate Protein |
|---|---|---|
| Skinless chicken breast, cooked | 3 ounces | 26 grams |
| Salmon, cooked | 3 ounces | 19–22 grams |
| Eggs | 2 large | 12–13 grams |
| Plain Greek yogurt | ¾ cup | 15–18 grams |
| Cottage cheese | ½ cup | 12–14 grams |
| Firm tofu | ½ cup | 10–20 grams |
| Lentils, cooked | ½ cup | 9 grams |
| Black beans, cooked | ½ cup | 7–8 grams |
| Edamame, cooked and shelled | ½ cup | 9 grams |
| Almonds | 1 ounce | 6 grams |
Protein amounts are approximate. Actual values depend on the product, variety, cooking method, and serving size. Check nutrition labels when precise amounts matter.
There is no single protein food that everyone with diabetes should eat. A variety of protein sources can help you meet your nutritional needs without making meals repetitive.
Best Animal-Based Proteins for Diabetes
Animal-based proteins generally provide all nine essential amino acids, which your body needs for building and maintaining tissues.
Many also provide vitamin B12, iron, zinc, and other nutrients. The main consideration is choosing options that provide protein without excessive saturated fat or sodium.
Chicken and Turkey
Skinless chicken and turkey are practical choices because they provide substantial protein with relatively little saturated fat.
A 3-ounce serving of cooked chicken breast provides approximately 26 grams of protein and contains virtually no carbohydrates.
Chicken and turkey are also versatile. You can use them in salads, soups, sandwiches, stir-fries, and simple dinners.
Healthier preparation methods include baking, roasting, grilling, and poaching. These methods allow you to add flavor without relying on heavy breading or deep-frying.
Fresh poultry is generally preferable to heavily processed products such as chicken nuggets, breaded patties, and some deli meats.
When buying ground turkey, check the label. Products made with skin and dark meat can contain considerably more fat than ground turkey breast.
Fish and Seafood
Fish is one of the most useful protein choices for people with diabetes, particularly because heart health deserves special attention.
People with diabetes have an increased risk of cardiovascular disease. Choosing protein foods that support heart health is therefore important, even when those foods do not directly lower blood sugar.
Fatty fish such as salmon, sardines, trout, and herring contain omega-3 fatty acids. These fats support cardiovascular health and can help lower elevated triglyceride levels.
Other good choices include cod, haddock, tilapia, shrimp, and scallops.
Most plain fish and seafood contain little or no carbohydrate. However, breading, sweet sauces, and certain marinades can add carbohydrates.
The American Heart Association recommends eating fish, particularly fatty fish, about twice a week.
You don’t need to buy expensive wild-caught salmon to benefit. Frozen fish and canned salmon or sardines can be nutritious and affordable alternatives.
When choosing canned seafood, check the sodium content, especially if you’re also managing high blood pressure.
Eggs
Eggs are an inexpensive and convenient source of high-quality protein.
One large egg provides approximately 6 grams of protein and contains very little carbohydrate.
Eggs also provide choline, vitamin B12, and other nutrients.
For someone with diabetes, eggs can be part of a balanced eating pattern. They can be boiled, poached, scrambled, or prepared as an omelet with vegetables.
The larger nutritional concern is often what accompanies the eggs.
For example, eggs served with vegetables and whole-grain toast offer a different nutritional balance than eggs served regularly with bacon, sausage, and heavily buttered biscuits.
Egg yolks contain cholesterol. Dietary cholesterol affects people differently, and saturated fat is often a more important consideration for blood cholesterol levels.
If you have elevated LDL cholesterol or cardiovascular disease, your healthcare professional or dietitian can help you decide how whole eggs fit into your eating plan.
Egg whites are another option when you want additional protein without the cholesterol found in yolks.
Lean Beef and Pork
You don’t necessarily have to eliminate beef or pork because you have diabetes.
The type of cut, portion size, and frequency of consumption are important.
Lean beef options include sirloin, tenderloin, and round cuts. Pork tenderloin and certain loin chops can also provide substantial protein without large amounts of saturated fat.
A reasonable starting portion for many meals is approximately 3 ounces of cooked meat, although individual needs vary.
Trim visible fat and choose baking, roasting, or grilling rather than deep-frying.
Because frequent consumption of red and processed meats is associated with health concerns, it makes sense to vary your protein choices instead of relying on beef or pork every day.
Replacing some red meat meals with fish, poultry, beans, or tofu can improve the overall nutritional balance of your diet.
Best Plant-Based Proteins for Diabetes
Plant-based proteins deserve a regular place in a diabetes-friendly eating plan.
Many provide fiber, unsaturated fats, vitamins, and minerals along with protein. They also tend to contain less saturated fat than fatty animal products.
You don’t need to become vegetarian to benefit. Simply replacing some animal-based meals with plant proteins can add variety and improve the overall quality of your diet.
Beans and Lentils
Beans and lentils are particularly useful because they provide both protein and fiber.
A half-cup of cooked lentils contains approximately 9 grams of protein and 8 grams of fiber.
Black beans, kidney beans, chickpeas, and pinto beans are also nutritious choices.
Fiber can slow the absorption of carbohydrates and help you feel satisfied after eating.
However, beans and lentils contain carbohydrates, so they can still raise blood sugar. This is especially important if you count carbohydrates to manage your diabetes.
The advantage is that beans provide more than carbohydrates alone. Their combination of fiber, protein, and other nutrients makes them a useful alternative to many highly refined foods.
Try adding beans to salads, soups, or chili. Lentils work well in vegetable soups, grain bowls, and as a partial replacement for ground meat in certain recipes.
Canned beans are convenient and nutritious. Choose no-salt-added varieties when possible, or rinse regular canned beans to reduce some of the sodium.
Tofu, Tempeh, and Edamame
Soy foods are another excellent way to include plant protein in your diet.
Tofu and tempeh provide complete protein, meaning they contain all nine essential amino acids.
Tofu has a mild flavor and absorbs seasonings easily. It works well in stir-fries, soups, and vegetable dishes.
Tempeh has a firmer texture and a slightly nutty flavor. It can be sliced, baked, or crumbled into recipes.
Edamame, which are immature soybeans, provide protein, fiber, and other nutrients. They can be served as a snack or added to salads and grain bowls.
Soy foods generally contain little saturated fat and can be useful alternatives to fatty meats.
If you haven’t tried tofu before, start with extra-firm tofu. Press out excess moisture, season it with garlic, ginger, or your favorite spices, and bake or sauté it.
You may find it easier to enjoy than you expected.
Nuts and Seeds
Almonds, walnuts, peanuts, pumpkin seeds, chia seeds, and other nuts and seeds can contribute protein to your diet.
They also provide unsaturated fats, fiber, and minerals.
However, nuts and seeds are not as concentrated a source of protein as chicken, fish, tofu, or Greek yogurt.
For example, one ounce of almonds provides approximately 6 grams of protein, along with a substantial amount of fat and calories.
That doesn’t make almonds unhealthy. It simply means they are often more useful as a snack or addition to a meal than as its primary protein source.
A small handful of unsalted nuts can be a convenient snack. You can also add chopped nuts or seeds to yogurt, oatmeal, or salads.
Choose varieties without sugary coatings, and pay attention to portions if you’re managing your weight.
What About Quinoa and Other Grains?
Quinoa is sometimes promoted as a high-protein food because it contains all nine essential amino acids.
A cooked cup provides approximately 8 grams of protein.
However, it also contains roughly 39 grams of carbohydrates.
Quinoa can be a nutritious part of a diabetes-friendly diet, but it is better considered a carbohydrate-containing food that contributes some protein rather than a primary protein source.
The same general principle applies to other grains.
If you’re counting carbohydrates, include these foods in your carbohydrate calculations even when they’re described as protein-rich.
Dairy and Dairy Alternatives That Provide Protein
Dairy foods can provide convenient protein along with calcium and other nutrients.
The main things to consider are added sugars, saturated fat, sodium, and the amount of protein in each serving.
Plain Greek Yogurt
Plain Greek yogurt is one of the most convenient protein-rich foods.
Depending on the brand, a 3/4-cup serving may provide approximately 15 to 18 grams of protein.
Greek yogurt generally contains less carbohydrate and more protein than many regular yogurts, although the amounts vary.
Choose plain, unsweetened varieties when possible.
Flavored yogurts can contain considerable added sugar, even when they’re marketed as healthy.
If plain yogurt tastes too tart, add fresh berries, cinnamon, or a few chopped nuts.
These additions provide flavor and texture without requiring a large amount of added sugar.
Cottage Cheese
Cottage cheese provides substantial protein with relatively few carbohydrates.
A half-cup serving typically contains approximately 12 to 14 grams of protein.
It can be eaten with sliced tomatoes, cucumber, fruit, or other foods you enjoy.
One consideration is sodium. Some cottage cheese products contain relatively large amounts, so compare labels if you need to limit salt.
Reduced-fat varieties can be useful if you’re watching saturated fat, but the best choice depends on the nutritional content of the particular product and your overall eating plan.
Unsweetened Soy Milk and Other Alternatives
Not all plant-based milk alternatives provide similar amounts of protein.
Unsweetened soy milk typically contains about 7 to 9 grams of protein per cup, making it comparable to cow’s milk.
Almond milk often contains only about 1 gram per cup, while oat milk generally provides less protein than soy milk and may contain more carbohydrates.
These differences matter if you’re relying on milk alternatives to help meet your protein needs.
Check the Nutrition Facts label for protein, total carbohydrates, added sugars, and calcium fortification.
Does Protein Raise Blood Sugar?
Protein generally has a smaller immediate effect on blood sugar than carbohydrates.
Foods such as eggs, chicken, fish, and plain tofu contain little carbohydrate, so they usually cause only a modest immediate glucose response when eaten by themselves.
However, protein does not automatically keep blood sugar stable, and it doesn’t cancel out carbohydrates eaten during the same meal.
Protein can stimulate insulin release. Large amounts of protein, especially when combined with fat and carbohydrates, may also influence blood glucose several hours after eating.
This delayed effect can be particularly important for people with type 1 diabetes or those who use mealtime insulin.
For example, adding an egg to a slice of whole-grain toast may make breakfast more satisfying, but the carbohydrates in the toast can still raise blood sugar.
Beans, yogurt, and milk also contain carbohydrates, even though they provide protein.
The practical approach is to consider the entire meal rather than assuming a food is automatically blood sugar-friendly because it contains protein.
For a fuller explanation of how different nutrients influence glucose levels, read How Food Affects Blood Sugar.
One important reminder: Protein-rich foods are not a substitute for fast-acting carbohydrates when treating low blood sugar. If you experience hypoglycemia, follow your healthcare team’s treatment instructions.
How Much Protein Do People With Diabetes Need?
There is no single daily protein target that works for everyone with diabetes.
Your needs depend on your age, body size, physical activity, overall nutritional status, and whether you have kidney disease or other medical conditions.
The American Diabetes Association does not recommend one ideal percentage of calories from protein for everyone with diabetes. Instead, protein intake should be individualized.
Understanding the Basic Protein Recommendation
The recommended dietary allowance, or RDA, for most healthy adults is 0.8 grams of protein per kilogram of body weight per day.
This is a general baseline designed to meet the needs of most healthy adults. It is not necessarily the ideal amount for every person with diabetes.
To understand the calculation, consider someone who weighs 150 pounds.
First, divide their weight by 2.2 to convert pounds to kilograms.
150 ÷ 2.2 = approximately 68 kilograms.
Then multiply by 0.8.
68 × 0.8 = approximately 54 grams of protein per day.
This provides a useful reference point, but it should not automatically be treated as a personalized target.
The table below shows how the calculation changes with body weight.
| Body Weight | Approximate RDA at 0.8 g/kg |
|---|---|
| 120 pounds | 44 grams daily |
| 150 pounds | 55 grams daily |
| 180 pounds | 65 grams daily |
| 200 pounds | 73 grams daily |
| 220 pounds | 80 grams daily |
These figures illustrate the standard adult RDA, not individualized diabetes treatment recommendations. For people with obesity or certain medical conditions, clinicians may use an adjusted or reference body weight when determining protein needs.
Protein Needs for Older Adults
Protein becomes particularly important as we age.
Older adults naturally tend to lose muscle mass over time, a process that can affect strength, mobility, and independence.
Adequate protein, combined with appropriate physical activity and resistance exercise, helps maintain muscle.
Some older adults may benefit from protein intake above the standard adult RDA.
However, the appropriate amount depends on nutritional status, kidney function, activity, and other health considerations.
If you’re over 65 and have diabetes, a registered dietitian can help you determine whether your current intake is sufficient.
Protein and Diabetic Kidney Disease
Kidney health is one of the most important considerations when deciding how much protein to eat.
Diabetes can damage the kidneys over time, making it harder for them to filter waste products from the blood.
If you have chronic kidney disease, your protein needs may differ from those of someone with normal kidney function.
For adults with diabetes and moderate to advanced chronic kidney disease who are not receiving dialysis, the American Diabetes Association generally recommends approximately 0.8 grams of protein per kilogram of body weight daily.
Some kidney nutrition guidelines consider lower intakes in selected circumstances, but restrictive diets require professional supervision because eating too little protein can contribute to malnutrition and muscle loss.
People receiving dialysis often need more protein, not less.
The important point is that you should not begin a high-protein or very low-protein diet on your own if you have kidney disease.
Your healthcare team can help you find an appropriate balance based on your kidney function, nutritional needs, and treatment.
Does Exercise Change Your Protein Needs?
Regular physical activity can influence how much protein your body needs.
Resistance training, in particular, increases the importance of adequate protein for muscle repair and maintenance.
Some physically active adults may benefit from consuming more than the standard RDA.
However, eating extra protein does not automatically improve blood sugar control or produce more muscle.
Exercise habits, total calorie intake, age, and overall health all influence the amount that makes sense.
If you are beginning a strength-training program or trying to preserve muscle as you age, consider discussing your protein intake with a registered dietitian.
Which Protein Foods Should You Limit?
People with diabetes don’t need to divide all foods into strictly good or bad categories.
However, some protein-rich foods are better eaten less frequently because of their saturated fat, sodium, or degree of processing.
Processed meats such as bacon, hot dogs, sausage, and many deli meats often contain substantial sodium and may contain significant saturated fat. Frequent consumption is associated with increased health risks.
Fatty cuts of red meat can contribute large amounts of saturated fat, which may raise LDL cholesterol.
Heavily breaded or fried meats and seafood can contain additional refined carbohydrates, calories, and saturated fat, depending on how they’re prepared.
Processed meat alternatives also deserve a label check. Some plant-based burgers and sausages contain substantial sodium or saturated fat, particularly when made with coconut oil.
You don’t have to eliminate every food you enjoy. Instead, make minimally processed protein sources your usual choices and keep less nutritious options occasional.
For a broader discussion of foods worth limiting, see Foods to Avoid With Diabetes.
Are Protein Powders and Shakes Good for People With Diabetes?
Protein powders and shakes can be convenient, but most people with diabetes do not need them.
If you can meet your protein needs through regular meals, whole foods generally offer additional nutrients, fiber, and other benefits that supplements may lack.
Still, protein supplements can be useful in certain situations.
For example, someone who has difficulty eating enough because of reduced appetite, illness, or other circumstances may find a protein shake easier to consume than a full meal.
They can also be convenient for people with demanding schedules or specific exercise-related nutritional needs.
Whey Protein vs. Plant-Based Protein Powders
Whey protein comes from milk and contains all nine essential amino acids.
Whey protein isolate generally contains less lactose and fewer carbohydrates than whey concentrate, although product formulations vary.
Some studies suggest whey protein consumed with or before meals may reduce post-meal glucose increases in certain people with type 2 diabetes.
However, the evidence does not establish that everyone with diabetes should take whey protein or that it can replace standard diabetes treatment.
Plant-based powders made from soy, pea, rice, or blended proteins are alternatives for people who avoid dairy.
The nutritional quality depends on the ingredients and formulation.
Neither whey nor plant-based protein powder is automatically better for blood sugar management.
What to Check on the Nutrition Label
Before buying a protein powder or ready-to-drink shake, compare:
- Protein per serving: Does the product provide a useful amount for your needs?
- Total carbohydrates: Some shakes contain much more carbohydrate than others.
- Added sugars: Sweetened products may contain significant amounts.
- Saturated fat: Compare products, particularly if you’re managing cholesterol.
- Serving size: Some containers contain more than one serving.
- Third-party testing: Independent certification can provide additional reassurance about product quality.
Be cautious of supplements claiming to reverse diabetes, dramatically improve insulin sensitivity, or eliminate the need for medication.
These claims are not reliable reasons to purchase a product.
If you have kidney disease, take multiple medications, or have difficulty meeting your nutritional needs, ask your healthcare professional before adding protein supplements.
Simple Ways to Include Healthy Protein in Your Meals
Getting enough protein doesn’t require complicated recipes or carefully measuring every bite.
A few everyday choices can help you include protein throughout the day.
| Meal | Simple Protein-Rich Idea |
|---|---|
| Breakfast | Plain Greek yogurt with berries and chopped nuts |
| Lunch | Grilled chicken salad with vegetables |
| Dinner | Baked salmon with broccoli and lentils |
| Snack | Hard-boiled egg with cucumber slices |
| Plant-based lunch | Tofu and vegetable stir-fry |
| Quick meal | Low-sodium canned salmon with whole-grain crackers and vegetables |
These are examples rather than prescribed meals. The right portions and carbohydrate amounts depend on your individual needs.
You may find it helpful to include some protein at breakfast, lunch, and dinner instead of consuming nearly all of it at one meal.
For example, someone who regularly eats toast alone for breakfast might add an egg or plain Greek yogurt.
At lunch, adding chickpeas or chicken to a vegetable salad can make it more satisfying.
For dinner, fish, tofu, or lean poultry can serve as the protein portion of a balanced plate.
You can also use the Diabetes Plate Method as a starting point: fill half your plate with non-starchy vegetables, one quarter with protein, and one quarter with carbohydrate-containing foods.

Frequently Asked Questions
What Is the Healthiest Protein for Someone With Type 2 Diabetes?
There isn’t one healthiest protein for everyone.
Fish, beans, lentils, tofu, skinless poultry, and plain Greek yogurt are all nutritious choices.
The best approach is usually to eat a variety of protein foods while considering saturated fat, sodium, carbohydrates, and your individual nutritional needs.
Can People With Diabetes Eat Eggs Every Day?
Eggs can fit into a healthy eating pattern for many people with diabetes.
However, whether eating whole eggs daily is appropriate depends on your overall diet, cholesterol levels, cardiovascular risk, and other health factors.
If you’re concerned about cholesterol, consider alternating whole eggs with egg whites or other protein sources.
Are Beans Good for Diabetes Even Though They Contain Carbohydrates?
Yes. Beans provide fiber, plant protein, vitamins, and minerals.
They do contain carbohydrates and can raise blood sugar, so portions matter.
Their fiber and nutritional content make them a useful part of many diabetes-friendly eating plans.
Is Too Much Protein Bad for People With Diabetes?
Very high protein intake is not necessary for diabetes management and may be inappropriate for certain people, particularly those with chronic kidney disease.
For people with healthy kidneys, ordinary protein intake from a balanced diet is generally not a concern.
However, there is no established benefit to consuming unusually large amounts of protein simply because you have diabetes.
Is Plant Protein Better Than Animal Protein for Diabetes?
Both can be part of a healthy diet.
Plant proteins such as beans, lentils, tofu, and nuts often provide fiber or unsaturated fats and may help reduce saturated fat intake when they replace fatty meats.
Animal proteins such as fish, eggs, and poultry provide high-quality protein and other important nutrients.
Rather than choosing one category exclusively, consider including a variety of nutritious protein sources.
Do You Need Protein at Every Meal?
You don’t need to follow a rigid rule, but including protein in regular meals can help you meet your daily nutritional needs.
Protein may also help meals feel more satisfying.
Your ideal meal pattern depends on your appetite, medications, activity, and overall eating plan.
Can Eating More Protein Lower Blood Sugar?
Not necessarily.
Protein generally has less immediate effect on blood glucose than carbohydrate, and including protein in balanced meals may change the glucose response.
However, simply increasing protein intake has not been shown to consistently improve blood sugar control for everyone with diabetes.
The overall quality of your diet, carbohydrate intake, physical activity, medications, and individual response remain important.
Final Thoughts
Choosing healthy protein foods is one part of managing diabetes, but it doesn’t need to be complicated.
Fish, poultry, eggs, beans, lentils, tofu, Greek yogurt, and other nutritious foods can all help you meet your protein needs.
The most useful approach is to choose a variety of protein sources, pay attention to portions, and consider the nutritional quality of the entire meal.
You don’t need to avoid all carbohydrates, follow an extreme high-protein diet, or depend on supplements.
If you have kidney disease, are losing muscle, or have other nutritional concerns, your healthcare team can help you determine how much protein is appropriate.
For most people, the goal is simply to build a balanced eating pattern that supports blood sugar management, heart health, and long-term well-being.
