Top 16 Best Foods for People with Diabetes

1. Fatty Fish

Fatty fish like salmon, mackerel, sardines, herring, and anchovies are among the healthiest foods for people with diabetes. These fish are rich in omega-3 fatty acids, specifically DHA and EPA, which provide significant cardiovascular benefits.

Since people with diabetes face an increased risk of heart disease and stroke, getting adequate omega-3s is particularly important. These healthy fats help protect blood vessel cells, reduce inflammatory markers, and improve arterial function. Regular consumption of fatty fish has been associated with lower risks of heart attacks and cardiovascular complications.

Additionally, fatty fish provides high-quality protein that promotes satiety and helps stabilize blood sugar levels. Aim to include fatty fish in your diet at least twice per week for optimal benefits.

2. Leafy Green Vegetables

Leafy greens such as spinach, kale, collard greens, and Swiss chard are nutritional powerhouses that offer minimal impact on blood sugar levels. These vegetables are extremely low in calories and digestible carbohydrates, making them ideal for diabetes management.

Rich in vitamins, minerals, and antioxidants, leafy greens provide substantial amounts of vitamin C, which acts as a potent antioxidant with anti-inflammatory properties. Research suggests that increasing vitamin C intake through dietary sources may help people with diabetes reduce inflammation and cellular damage while improving serum vitamin C levels.

You can enjoy leafy greens in salads, smoothies, sautés, or as side dishes without worrying about blood sugar spikes.

3. Avocados

Avocados are exceptional for people with diabetes, containing less than one gram of sugar, minimal carbohydrates, high fiber content, and beneficial healthy fats. These characteristics mean avocados won’t cause significant blood sugar elevation.

Studies have associated avocado consumption with lower body weight and body mass index (BMI), which is particularly relevant since obesity increases diabetes risk. Beyond weight management, avocados may have properties specifically related to diabetes prevention through compounds that help reduce insulin resistance.

Add avocados to salads, sandwiches, or enjoy them as a standalone snack for a nutritious, blood sugar-friendly option.

4. Eggs

Eggs offer multiple benefits for people with diabetes. They can help reduce inflammation, improve insulin sensitivity, increase HDL (good) cholesterol levels, and modify the size and shape of LDL (bad) cholesterol particles.

Research has shown that regular egg consumption as part of a balanced diet doesn’t increase heart disease risk factors in people with diabetes. In fact, eggs may help improve blood pressure in adults with prediabetes when consumed regularly.

Eggs are versatile, affordable, and provide high-quality protein along with essential nutrients, making them an excellent choice for breakfast or any meal.

5. Chia Seeds

Chia seeds are remarkably beneficial for diabetes management. While they contain approximately 12 grams of carbohydrates per ounce, 11 of those grams come from fiber, which doesn’t raise blood sugar levels.

The viscous fiber in chia seeds can actually lower blood sugar by slowing the rate at which food moves through your digestive system and is absorbed. Studies involving adults with type 2 diabetes have shown that chia seed consumption supports weight loss and helps maintain good glycemic control.

Chia seeds also help reduce blood pressure and inflammatory markers. Sprinkle them on yogurt, add them to smoothies, or make chia pudding for a nutritious treat.

6. Beans and Legumes

Beans and other legumes are rich in B vitamins, beneficial minerals including calcium, potassium, and magnesium, and fiber. They have a very low glycemic index, which is crucial for diabetes management.

Studies involving thousands of participants at high cardiovascular disease risk have found that higher legume consumption is associated with a reduced chance of developing type 2 diabetes. The combination of protein, fiber, and complex carbohydrates in beans provides sustained energy without causing rapid blood sugar spikes.

Include kidney beans, black beans, pinto beans, lentils, and chickpeas in your diet through soups, salads, or as side dishes.

7. Greek Yogurt

Greek yogurt is an excellent dairy choice for people with diabetes. Research has linked daily yogurt consumption to a lower risk of developing type 2 diabetes, and dairy products are associated with reduced risks of overweight and obesity in people with type 2 diabetes.

Greek yogurt contains only 6-8 grams of carbohydrates per serving, which is lower than regular yogurt. It’s also higher in protein, which can promote weight loss by reducing appetite and decreasing overall calorie intake. The high levels of calcium, protein, and conjugated linoleic acid (CLA) in yogurt help keep you feeling satisfied for longer periods.

Choose plain, unsweetened Greek yogurt and add your own fresh berries or a small amount of natural sweetener if needed.

8. Nuts

Regular nut consumption offers numerous benefits for people with diabetes. Research shows that eating nuts may reduce inflammation, prevent weight gain, and improve heart health.

Studies involving thousands of participants with type 2 diabetes have found that eating tree nuts like walnuts, almonds, hazelnuts, and pistachios lowers the risk of heart disease. Nuts can also help improve blood glucose levels, with some research showing that daily walnut consumption improved blood glucose management.

Since people with type 2 diabetes often have elevated insulin levels linked to obesity, the blood sugar benefits of nuts are particularly significant. Enjoy a small handful of mixed nuts as a snack, or add them to salads and other dishes.

9. Broccoli

Broccoli is a highly nutritious vegetable that’s excellent for diabetes management. A half-cup of cooked broccoli contains only 27 calories and 3 grams of digestible carbohydrates, along with important nutrients like vitamin C and magnesium.

Research indicates that consuming broccoli can lead to reductions in blood glucose levels. This benefit is likely due to sulforaphane, a compound formed when the body converts glucosinolates found in broccoli. Sulforaphane is then utilized in various metabolic processes that support blood sugar control.

Enjoy broccoli steamed, roasted, or raw with healthy dips for a nutrient-dense, low-carb vegetable option.

10. Extra-Virgin Olive Oil

Extra-virgin olive oil contains oleic acid, a monounsaturated fat that may improve glycemic management and reduce both fasting and post-meal triglyceride levels. This is particularly important since people with diabetes often struggle with blood sugar management and have elevated triglyceride levels.

Olive oil is rich in antioxidants called polyphenols, which reduce inflammation, protect blood vessel cells, prevent LDL cholesterol oxidation, and help decrease blood pressure. Multiple studies have demonstrated that olive oil consumption significantly reduces heart disease risk.

Choose extra-virgin olive oil from reputable sources, as it’s unrefined and retains the beneficial antioxidants and properties that make it so healthy. Use it for cooking, salad dressings, and as a finishing oil for vegetables.

11. Flaxseeds

Flaxseeds are packed with heart-healthy omega-3 fatty acids, fiber, and unique plant compounds called lignans. A portion of their insoluble fiber consists of lignans, which may help decrease heart disease risk and improve blood sugar management.

Research reviews examining numerous clinical trials have found significant associations between flaxseed supplementation and reductions in blood glucose levels. Flaxseeds may also help lower blood pressure, though studies on their effects on insulin resistance show mixed results.

Ground flaxseeds are easier to digest than whole seeds. Add them to smoothies, sprinkle on cereals, or incorporate into baked goods.

12. Apple Cider Vinegar

Apple cider vinegar and plain vinegar have gained attention for their potential health benefits in diabetes management. Research involving people with type 2 diabetes has shown that vinegar has beneficial effects on fasting blood sugar levels and hemoglobin A1C results.

Apple cider vinegar may help improve blood sugar spikes after meals and enhance insulin sensitivity, though more research is needed to fully confirm these benefits.

To incorporate apple cider vinegar into your diet, start with one teaspoon in a glass of water before meals, gradually working up to a maximum of four tablespoons per day. Always dilute vinegar to protect your tooth enamel and digestive system.

13. Strawberries and Berries

Strawberries and other berries are high in antioxidants known as anthocyanins, which give them their vibrant colors. They also contain polyphenols, beneficial plant compounds with antioxidant properties.

Studies have shown that regular consumption of polyphenols from strawberries and cranberries can improve insulin sensitivity in adults with overweight and obesity. This is crucial because low insulin sensitivity can cause blood sugar levels to become dangerously elevated.

Berries are relatively low in sugar compared to other fruits and can be enjoyed fresh, frozen, or added to yogurt, salads, and smoothies.

14. Garlic

Despite its small size and low calorie content, garlic is incredibly nutritious. One clove contains small amounts of manganese, vitamin B6, vitamin C, selenium, and fiber, providing nutritional value for minimal calories.

Research indicates that garlic contributes to improved blood glucose management and can help regulate cholesterol levels. Its anti-inflammatory and antioxidant properties offer additional health benefits for people with diabetes.

Add fresh or roasted garlic to savory dishes for enhanced flavor and potential health benefits.

15. Squash

Squash varieties, including butternut, acorn, and spaghetti squash, are among the healthiest vegetables for people with diabetes. This dense, filling food is fairly low in calories and has a low glycemic index.

Like most vegetables, squash contains beneficial antioxidants and has less sugar than sweet potatoes, making it an excellent alternative. Research has shown that compounds in squash may improve insulin tolerance and decrease serum glucose levels.

Squash can be roasted, steamed, or used as a low-carb pasta alternative in the case of spaghetti squash.

16. Shirataki Noodles

Shirataki noodles are wonderful for diabetes management and weight control. These unique noodles are made from glucomannan, a type of viscous fiber extracted from konjac root.

Glucomannan helps you feel full and satisfied while having minimal impact on blood sugar. Research has shown that it can reduce blood sugar levels after eating and improve heart disease risk factors in people with diabetes and metabolic syndrome.

Shirataki noodles require thorough rinsing before use due to their packaging liquid. After rinsing, cook them in a skillet over high heat for several minutes to achieve a better texture.

Foods to Limit or Avoid with Diabetes

Understanding which foods to limit is just as important as knowing which foods to include in your diet. Certain foods can cause rapid blood sugar spikes, contribute to weight gain, or negatively impact heart health.

Refined Grains

White bread, white pasta, and white rice are high in carbohydrates but low in fiber, causing faster blood sugar increases compared to whole grain alternatives. Research has demonstrated that whole grain options are significantly more effective at stabilizing blood sugar levels after meals.

Sugar-Sweetened Beverages

Sodas, sweet teas, energy drinks, and fruit punches lack important nutrients while containing concentrated amounts of sugar that can cause dramatic blood sugar spikes. These beverages provide empty calories without the fiber or nutrients that help moderate glucose absorption.

Fried Foods

Foods like french fries, fried chicken, and mozzarella sticks contain unhealthy trans fats linked to increased heart disease risk. They’re also typically high in calories, which can contribute to weight gain when consumed regularly.

Alcohol

People with diabetes should approach alcohol cautiously, as it can increase the risk of low blood sugar, especially when consumed on an empty stomach. If you choose to drink, consult your healthcare provider about safe consumption guidelines.

Breakfast Cereals

Many breakfast cereals contain as much sugar as desserts. When shopping for cereal, carefully check nutrition labels and select varieties low in added sugar. Better yet, choose oatmeal and sweeten it naturally with fresh fruit.

Candy and Sweets

Candy contains high amounts of sugar per serving and typically has a high glycemic index, leading to rapid blood sugar spikes and crashes. Save sweet treats for occasional indulgences in very small portions.

Processed Meats

Bacon, hot dogs, salami, and deli meats are high in sodium, preservatives, and potentially harmful compounds. Processed meats have been associated with higher risks of heart disease, making them particularly problematic for people with diabetes.

Fruit Juice

While 100% fruit juice can be enjoyed occasionally in small amounts, whole fruits are always the better choice. Fruit juice contains all the carbohydrates and sugar found in fresh fruit but lacks the fiber needed to help stabilize blood sugar levels.

Strategies for Creating a Diabetes-Friendly Eating Plan

The Plate Method

The plate method is a simple, effective approach to blood sugar management that doesn’t require tracking or measuring. To use this method:

• Fill half your plate with nonstarchy vegetables like leafy greens, broccoli, cauliflower, or peppers
• Dedicate one quarter of your plate to lean proteins such as chicken, fish, eggs, tofu, or lean beef
• Use the remaining quarter for healthy carbohydrates including whole grains, legumes, starchy vegetables, or fruit
• Pair your meal with water, unsweetened tea, or another low-calorie beverage

Understanding the Glycemic Index

The glycemic index (GI) measures how much specific foods raise blood sugar levels. Foods are categorized as high, low, or medium GI based on their impact. Using the GI as a guide, you can make better choices by:

• Choosing low or medium GI foods whenever possible
• Limiting high GI foods that cause rapid blood sugar spikes
• Combining high GI foods with proteins or healthy fats to moderate their effect

Carbohydrate Counting

Carbohydrate counting involves tracking the grams of carbs you consume daily. This method can be particularly useful for people who use insulin, as it allows for more precise dosing.

The appropriate amount of carbohydrates varies based on individual factors like age, size, activity level, and medication regimen. Work with a registered dietitian or healthcare provider to determine your personalized carbohydrate targets.

Sample Daily Menu for Diabetes Management

Here’s a sample one-day menu featuring diabetes-friendly foods:

Breakfast: Vegetable omelet with broccoli, mushrooms, and bell peppers cooked in olive oil

Morning Snack: Small handful of raw almonds

Lunch: Grilled salmon over mixed greens with cherry tomatoes, avocado, cucumber, red onion, and olive oil vinaigrette

Afternoon Snack: Plain Greek yogurt topped with fresh strawberries and crushed walnuts

Dinner: Herb-roasted chicken breast with quinoa and roasted asparagus

Evening Snack: Sliced vegetables with hummus

Additional Tips for Blood Sugar Management

Portion Control

Even healthy foods can impact blood sugar if consumed in excessive amounts. Pay attention to portion sizes, especially for carbohydrate-containing foods, to maintain stable glucose levels throughout the day.

Meal Timing

Eating at consistent times each day helps regulate blood sugar levels and makes diabetes management more predictable. Avoid skipping meals, which can lead to low blood sugar or overeating later.

Stay Hydrated

Adequate water intake supports kidney function and helps your body eliminate excess glucose through urine. Aim for at least eight glasses of water daily, adjusting based on activity level and climate.

Physical Activity

Regular exercise works synergistically with healthy eating to improve insulin sensitivity and blood sugar control. Consult your healthcare provider about appropriate exercise recommendations for your situation.
