60+ Foods To Avoid With Prediabetes (And What To Eat Instead)

Prediabetes is when your blood sugar levels are high but not high enough to be diagnosed as type 2 diabetes.

Meeting with a dietitian immediately after getting a diagnosis can be helpful.

They can offer evidence-based dietary and lifestyle suggestions to help you manage your blood sugar levels. 

Keep reading to learn which foods you may want to avoid if you have prediabetes—and discover delicious alternatives you can enjoy every day.

Sugary Drinks

Sugar-sweetened beverages contain high amounts of glucose (sugar) that are rapidly absorbed into your bloodstream, making it hard to maintain stable blood glucose levels. 

Examples of sugary drinks you may want to avoid include:

• Juice. 
• Store-bought smoothies. 
• Sodas. 
• Fruity cocktails. 
• Sports drinks. 
• Novelty coffee beverages (frappuccino, etc.)

Try This Alternative

Here are some refreshing drinks without added sugars: 

• Water infused with fresh fruits and herbs. 
• Plain tea, like chamomile, mint, Earl Grey, or green tea. 
• Plain sparkling water. Optional: add lemon juice. 

Artificially flavored beverages shouldn’t affect your blood sugar levels, and you can review these products with a dietitian.

Commercially prepared baked sweets may contain high amounts of added sugar and fat. 

Although an occasional cookie shouldn’t interfere with your overall health goals, you may benefit from reducing your intake of these foods:

Carbohydrates offer a rich energy source your body needs to function.

High-quality carbohydrates are more desirable for blood sugar control and contain fiber and other essential nutrients.

Here are delicious options to try: 

• Ancient whole grains (quinoa, teff, millet, amaranth, bulgur, etc.)

Try to limit your intake of: 

• Bacon.
• Hot-dogs. 
• Sausages. 
• Marbled deli meats, like salami. 
• Jerky. 
• Cured beef and other meats.

High-Fat Dairy Products 

Animal-based dairy products contain calcium, protein, and other essential nutrients.

However, high-fat products also contain saturated fats, which may increase your risk of heart disease or stroke.

Try to limit your intake of: 

• Whole milk or 2% milk (per the ADA.) 
• Cream. 
• Ice-cream. 
• Whole milk yogurt (3.5% and higher.) 
• Butter. 
• Full-fat cheeses. 
• Sour cream.

Fortunately, plenty of low-fat dairy products are available at the grocery store.

In addition to choosing reduced-fat products, buy plain options whenever possible to decrease your intake of added sugars. 

• Skim milk (1% or less.) 
• Fat-free or low-fat cheese. 
• Low-fat yogurt. 
• Low-fat sour cream. 

Your dietitian may recommend a low-fat ice cream brand or alternative frozen treat upon request.

Fried Foods

Fried foods are considered ultra-processed and generally have high levels of saturated fats—with low amounts of fiber.

Some research suggests that regularly eating fried foods can increase your risk of type 2 diabetes and may not be the best choice while trying to manage prediabetes. 

Try to avoid these fried foods: 

• Onion rings. 
• French fries. 
• Deep-fried pickles. 
• Donuts. 
• Potato chips or corn chips.
• Falafel. 
• Chicken wings. 
• Chicken nuggets or tenders.  
• Tempura (Japanese deep-fried foods.)

• Air-fry vegetable chips. 
• Roasted parsnips fries. 
• Baked chickpea balls. 
• Grilled cauliflower wings. 
• Baked potato with low-fat sour cream and chives. 
• Broiled, seasoned vegetables. 

Experimenting with new recipes is one of the best ways to increase your comfort level in the kitchen. 

Alcohol

Too much alcohol has been linked with higher blood sugar levels and A1c.

If you want to drink, ask your healthcare team how many drinks you can have per week.

Until then, try to limit your intake of these beverages:

• Beer. 
• Wine. 
• Spirits.
• Liquors. 
• Cocktails. 
• Canned drinks. 

Try This Alternative

Premixed alcohol-free beverages may be an appropriate substitute, depending on their carbohydrate content. 

If you’re craving a carbonated drink, try having sparkling water flavored with fresh lime and herbs. 

Trans Fats

Everyone should be aware of trans fats and limit their intake as much as possible.

Trace amounts are naturally found in dairy and animal meats, but manufactured trans fats, like partially hydrogenated oils, are considered more hazardous to your health. 

Some foods that may contain trans fats include: 

• Shortening. 
• Frozen meals. 
• Commercial baked goods (fresh and frozen). 
• Microwave popcorn. 
• Fried foods. 

Try This Alternative

The FDA has banned artificial trans fats from food products as of 2020, but reading food labels is still good practice.

Adults who follow a 2000-calorie meal plan (the energy value used to calculate most nutrition labels) should aim for less than 2.2g/day of trans fat. 

Choosing whole, minimally processed foods is a great way to avoid artificial trans fats. 

Packaged Snack Foods

Packaged snack foods are usually processed to increase their shelf life and flavor.

They may contain higher amounts of sugar and sodium compared to fresh options. 

Examples of packaged snack foods you may want to avoid include: 

• Chips. 
• Snack mixes (Bits and Bites, Chocolate trail mix, etc.) 
• Candies.

Sugary Breakfast Cereals

Sweetened breakfast cereals may contain high amounts of added sugars while having lower levels of fiber.

This nutritional profile may rapidly raise your blood sugar levels, possibly leading to a sugar spike. 

Here are a few examples of sugary breakfast cereals to avoid: 

• Frosted Shreddies. 
• Fruit Loops. 
• Cap’n Crunch. 
• Honey Coated Shreddies. 
• Lucky Charms.

• Plain Cheerios. 
• Grape Nuts. 
• Weetabix whole grain cereal. 

Frozen Meals

Frozen meals have been served since the 50s, and their convenience continues to make them popular. 

However, modern products are considered ultra-processed and can have higher sodium, sugar, and saturated fat levels, which could make it hard to stabilize your blood sugar levels. 

Try This Alternative

If you have a frozen meal, pair it with whole foods to increase the nutritional quality of your meal.

For example, add a fresh salad or a side of air-fried or microwaved vegetables. 

Compare food labels of possible options to pick the best product.

Choose a frozen meal with lower amounts of sodium, saturated fats, trans fats, and added sugars. 

Jelly and Jam

Jelly, jam, and other sweet ingredients may affect blood sugar levels.

Other sweet spreads and syrups to keep an eye on include: 

• Honey. 
• Maple syrup. 
• High fructose corn syrup. 
• Chocolate or butterscotch sauce. 
• Compote. 
• Fruit chutney. 
• Fruit curd.

Takeaway

Your dietary choices directly impact your blood sugar levels. Enjoy foods with fiber, healthy fats, protein, and high-quality carbohydrates to optimize your levels.

Instead, consider working with a dietitian to learn how to build balanced meals.
