List of Foods to Avoid With Diabetes (Type 1 and Type 2)

Diabetes is a chronic condition marked by high blood sugar levels, also known as hyperglycemia. Today, nearly 90% of people with diabetes have type 2 diabetes, making it one of the most common metabolic diseases worldwide.

Whether you have type 1 or type 2 diabetes, diet plays a key role in managing blood sugar levels and preventing complications. While no food is completely “forbidden,” some foods can cause sharp spikes in blood glucose and should be limited or avoided.

In this guide, you’ll discover:

• Foods to avoid with type 1 diabetes

• Foods to avoid with type 2 diabetes

• How the glycemic index affects blood sugar

• What to eat instead

• A sample daily menu for people with diabetes

Foods to Avoid With Type 1 Diabetes

What Is Type 1 Diabetes?

Type 1 diabetes is an autoimmune disease. The immune system attacks the insulin-producing cells of the pancreas, preventing the body from regulating blood sugar properly.

Unlike common myths, there are no strictly forbidden foods for people with type 1 diabetes. The key is portion control, carbohydrate counting, and choosing foods that help maintain stable blood sugar levels.

Foods to Limit With Type 1 Diabetes

People with type 1 diabetes should limit foods with a high glycemic index (GI) and highly processed products, including:

• Sweetened yogurts and Greek yogurt with added sugar

• Dessert creams and puddings

• Cheese with more than 40% fat

• Fatty meats (lamb, breaded meats, nuggets, processed meats)

• Fried foods

• White rice

• French fries and chips

• Ready-made meals

• Pastries and baked goods

• Sugary breakfast cereals

• Dried fruits and fruits in syrup

• Mayonnaise

• Candy and ice cream

• Sugary drinks, sodas, and alcohol

Better alternatives include whole grains, vegetables, legumes, tofu, zucchini, broccoli, and sweet potatoes.

Foods to Avoid With Type 2 Diabetes

What Is Type 2 Diabetes?

Type 2 diabetes develops when the body becomes resistant to insulin or can no longer produce enough of it. It is strongly linked to lifestyle factors such as poor diet, excess weight, and physical inactivity.

Managing type 2 diabetes focuses on:

• Stabilizing or losing weight

• Reducing portion sizes

• Eating at regular times

• Increasing muscle mass through physical activity

Muscle tissue uses glucose efficiently, which helps improve blood sugar control.

Foods to Limit or Avoid With Type 2 Diabetes

Foods that raise blood sugar too quickly should be drastically reduced:

• White bread

• White sugar

• White pasta and overcooked white rice

• Pastries and baked desserts

• Honey

• Fruit juices

• Sodas

• Alcohol

• Ultra-processed foods (frozen pizzas, packaged meals, snack foods, sausages, candy, sweetened cereals, instant soups)

These foods cause rapid glucose absorption, leading to fat storage and poor glycemic control.

Understanding the Glycemic Index (GI)

The glycemic index (GI) measures how fast carbohydrates raise blood sugar levels. It ranges from 0 to 100.

• Low GI foods (below 55) → slow sugar absorption, stable blood sugar

• High GI foods (above 70) → rapid blood sugar spikes

Proteins, fiber, and healthy fats help lower the overall GI of a meal, which is why balanced meals are essential for people with diabetes.

What Should People With Diabetes Eat?

Foods to avoid with diabetes are mainly those high in sugar or with a high GI. Occasional treats are possible, but best eaten at the end of a meal and not on an empty stomach.

Focus on:

• Whole fruits and vegetables

• Whole and semi-whole grains

• Legumes (lentils, chickpeas, beans)

• Lean proteins

• Healthy fats

Regular mealtimes, hydration, and physical activity are just as important as food choices. If symptoms worsen or blood sugar becomes difficult to control, always consult your doctor.

Sample Daily Menu for Someone With Diabetes

Breakfast

• Bran bread with a small amount of butter

• Plain fat-free yogurt (no sugar)

• Grapefruit

• Unsweetened tea

Lunch

• Endive salad with fat-free yogurt dressing and olive oil

• Steamed skate fish

• Brown rice with steamed zucchini

• Goat cheese

• Peach

Dinner

• Leeks with vinaigrette

• Roast veal

• Polenta with oven-baked tomatoes

• Fruit-flavored fat-free yogurt (no added sugar)

What Can a Person With Diabetes Eat for Dessert?

Some fruits are higher in sugar and should be limited, such as:

• Bananas

• Mangoes

• Cherries

Better low-GI fruit choices include:

• Apples

• Pears

• Peaches

• Kiwis

• Oranges and citrus fruits

• Berries

Whole fruits are always better than fruit juice. For better blood sugar control, pair fruit with protein or fiber, such as yogurt or a small amount of nut butter.

Remember: what you eat matters—but when you eat it matters too.

Conclusion

Managing diabetes isn’t about strict food bans—it’s about smart choices, balance, and consistency. By limiting high-sugar and ultra-processed foods and prioritizing low-GI, fiber-rich meals, people with both type 1 and type 2 diabetes can maintain healthier blood sugar levels and reduce long-term risks.
