Foods to Avoid With Diabetes: Essential Eating Tips and What to Skip
Learn which foods to limit or avoid with diabetes and discover healthier choices for blood sugar and heart health.
If you have diabetes, making the right nutritional choices can significantly impact your blood sugar levels, heart health, and overall well-being. Certain foods can cause blood glucose to spike or contribute to long-term health risks such as heart disease. Understanding which foods and drinks to avoid and why can empower you to make better choices for your condition.
Why Food Choices Matter for Diabetes
Diabetes disrupts your body’s ability to process blood sugar, also known as blood glucose. Since carbohydrates have the greatest influence on blood sugar, and unhealthy fats and sodium can increase the risk of related complications, being mindful of what you eat is crucial. A balanced diet focused on unprocessed, nutrient-dense foods can help keep blood sugar stable, aid in weight management, and lower the risk of heart disease and stroke.
Foods and Drinks to Avoid With Diabetes
Some foods rapidly increase blood sugar or contribute to other complications. Here are the main categories and specific foods to watch out for:
1. Sugary Foods and Drinks
- Sugary beverages: Soda, sweetened teas, energy drinks, and fruit punch raise blood sugar quickly and provide little nutrition.
- Sweet snacks and desserts: Candy, cookies, cakes, doughnuts, muffins, and pastries are high in sugar and easily digested carbs that cause sharp blood sugar spikes.
- Sugary cereals and granola bars: Many breakfast cereals and snack bars are packed with added sugars, even when labeled as “healthy.”
- Dried and canned fruit: These often contain added sugars or concentrated natural sugars that increase blood glucose. Opt for whole, fresh fruit instead.
- Syrups and sweeteners: Maple syrup, honey, agave nectar, and flavored syrups add extra sugar and calories without significant nutritional value.
2. Refined and Processed Carbohydrates
- White bread, white rice, and white pasta: Stripped of fiber and nutrients, these foods are rapidly broken down into glucose, leading to elevated blood sugar.
- Baked goods made with refined flour: Doughnuts, croissants, pizza dough, and most commercial bakery items act like pure sugar in the body.
- Crackers, chips, and snack foods: Many processed snacks are made with refined grains and added sugars or starches, which can quickly raise blood glucose.
3. Saturated and Trans Fats
- Fried foods: French fries, fried chicken, fried fish, and other deep-fried items are high in unhealthy fats that can raise cholesterol and increase the risk of heart disease.
- Processed meats: Bacon, sausages, hot dogs, deli meats, and ribs tend to contain high levels of saturated fat and sodium.
- High-fat dairy: Whole milk, heavy cream, and full-fat cheeses increase saturated fat intake.
- Packaged baked goods: Doughnuts, pies, and processed desserts often contain trans fats.
- Shortening and stick margarine: These artificial fats increase cardiovascular risk and may contribute to insulin resistance.
4. Excess Sodium
- Processed and packaged foods: Many canned soups, frozen meals, condiments, and sauces are high in sodium, which may worsen high blood pressure, a common concern for people with diabetes.
- Salty snacks: Potato chips, pretzels, and salted nuts can quickly add up in sodium.
5. High-Cholesterol Foods
- Organ meats: Such as liver, which are high in cholesterol and should be limited.
- Egg yolks: Best consumed in moderation, especially if you have elevated cholesterol.
- High-fat cuts of meat: Limit fatty steaks, processed sausages, and organ meats.
6. Alcohol
- Cocktails and mixed drinks: Many contain significant added sugars.
- Overconsumption of alcohol: It can cause swings in blood sugar and interfere with diabetes medications.

7. Artificial Sweeteners
- Sugar substitutes: Although low in calories, some studies suggest artificial sweeteners may impact insulin sensitivity and gut health. Moderation is key, and whole foods are preferable if possible.
Why These Foods Should Be Limited or Avoided
- Sugary and refined carbs rapidly increase blood glucose and can lead to energy crashes, weight gain, and increased insulin resistance.
- Saturated and trans fats raise LDL (“bad”) cholesterol, increasing the risk of heart disease and stroke—which people with diabetes are already at higher risk for.
- Excess sodium can worsen high blood pressure and heart disease risk.
- Processed foods tend to combine sugar, sodium, and unhealthy fats, making them particularly problematic for diabetes management.
Better Choices: Foods That Support Healthy Blood Sugar
Focusing on what you can eat is just as important as knowing what to limit. Here are some healthy swaps to help manage diabetes:
| Eat More | Eat Less |
|---|---|
| Whole grains (brown rice, quinoa, oats) | White rice, white bread, regular pasta |
| Fresh fruits (in moderation) | Canned fruit in syrup, sweetened fruit juices |
| Non-starchy vegetables (leafy greens, broccoli, peppers) | Fried vegetables, vegetables in cream sauces |
| Lean proteins (skinless poultry, fish, tofu, legumes, eggs) | Bacon, sausage, hot dogs, fried meats |
| Healthy fats (olive oil, avocado, nuts in moderation) | Butter, margarine, shortening, processed snacks |
| Water, unsweetened tea, black coffee | Sugary drinks, soda, sweetened tea |
| Herbs and spices for flavor | Salt, salty sauces, packaged seasoning |
Expert-Recommended Strategies for Managing Your Diet
- Eat regular meals: Maintain a consistent meal schedule to help stabilize blood sugar levels throughout the day.
- Watch portion sizes: Use the plate method—fill half with non-starchy vegetables, a quarter with lean protein, and a quarter with whole grains or starchy vegetables.
- Read nutrition labels: Pay particular attention to the amount of carbohydrates, added sugars, saturated fat, and sodium in packaged foods.
- Spread carbs throughout the day: Instead of consuming large amounts of carbohydrates at once, include small amounts with each meal to minimize spikes in blood sugar.
- Consult a dietitian: For personalized advice, especially if you’re newly diagnosed or have other health conditions.
Common Foods and How to Make Healthier Swaps
- Candy ➔ Try fresh berries, a small piece of dark chocolate, or air-popped popcorn for a treat.
- Granola bars ➔ Make your own snack mix with nuts and seeds, or look for snack bars with minimal added sugar and whole ingredients.
- Breakfast cereal ➔ Choose unsweetened oatmeal topped with fruit and nuts rather than sugary cereals.
- Rice ➔ Opt for brown rice, quinoa, or cauliflower rice to boost fiber and lower glycemic impact.
- Corn, peas, potatoes ➔ Swap for leafy greens, broccoli, or bell peppers to keep carbs in check.
- Fried foods ➔ Bake, grill, or steam foods instead of frying to reduce unhealthy fats.
Frequently Asked Questions (FAQs)
Q: Do I have to cut out all carbohydrates if I have diabetes?
No. Carbohydrates are an important source of energy. The goal is to focus on high-fiber, unprocessed carbs like whole grains, legumes, and vegetables, spread evenly throughout the day.
Q: Can I eat sweets or desserts at all?
Occasional, small portions of sweets can fit into many diabetes meal plans—especially if you count the carbohydrates and balance them with other foods. Focus on moderation and be mindful of added sugars.
Q: What kind of fats are safe to eat?
Choose unsaturated fats (found in olive oil, canola oil, nuts, and avocados) over saturated and trans fats. Avoid deep-fried foods, processed snacks, and fatty meats.
Q: Are sugar-free products safe for people with diabetes?
Sugar-free does not always mean healthy. Many sugar-free products contain artificial sweeteners or other additives that can still impact blood sugar or general health if overconsumed.
Q: Can I drink alcohol if I have diabetes?
Moderation is key. Alcohol can affect blood sugar levels and interact with some diabetes medications. Speak with your healthcare provider about safe limits and check your blood sugar after drinking.
Takeaway: Building a Sustainable Diabetes Meal Plan
Living well with diabetes means learning how foods affect your body and making balanced, enjoyable choices. Avoiding or limiting foods high in sugar, refined carbs, unhealthy fats, and excessive sodium is essential. Prioritize whole, nutrient-dense foods and don’t hesitate to ask a registered dietitian for support in creating a plan tailored to your needs.
Remember: Staying informed and proactive about your food choices is one of the most effective ways to take control of your diabetes and overall health.
