Prediabetes Grocery List: What to Buy and What to Skip

Last updated: July 2026 · Written by Sarah Mitchell

The first time I walked into my regular grocery store after my doctor told me I had prediabetes, I felt lost. My A1C was 6.1, and I had a pamphlet in my purse telling me to “eat healthier,” but standing in front of 40 kinds of bread, I had no idea what that actually meant.

So I did what I do best. I made a list. A real one, aisle by aisle, that I could print and stick in my bag. Over the next several months that list helped me bring my A1C down to 5.4, and I still shop from a version of it today.

This is that grocery list, cleaned up and expanded, so you can walk into any store and know exactly what to reach for and what to leave on the shelf. No guessing, no perfect eating required. Just a steady cart that keeps your blood sugar calmer.

How to Think About Your Cart

Before we go aisle by aisle, here is the simple idea that made everything click for me. Foods raise blood sugar based mostly on their carbohydrates, and how fast those carbs hit depends on fiber, protein, and fat riding along with them.

So a plate of grilled chicken and broccoli barely moves the needle, while a bagel sends it soaring. When you build your cart around protein, vegetables, and fiber, you are stacking the deck in your favor without counting a single thing.

The American Diabetes Association recommends filling half your plate with non-starchy vegetables, a quarter with lean protein, and a quarter with quality carbs. Your grocery cart should look the same way. If you want the food-by-food details, my guide on what to eat with prediabetes breaks it down further.

The Master Buy-This, Skip-This Table

Here is the quick reference version. Print this, fold it, and keep it in your wallet. I go into each section below.

Aisle	Buy This	Skip This
Protein	Chicken, turkey, eggs, salmon, tuna, sardines, tofu, tempeh	Breaded nuggets, bacon, deli salami, hot dogs
Vegetables	Broccoli, spinach, peppers, zucchini, cauliflower, green beans	Fried veggie sides, canned veggies in heavy sauce
Fats	Olive oil, avocado, nuts, seeds, natural nut butter	Margarine, hydrogenated oils, sweetened nut spreads
Grains & legumes	Oats, quinoa, brown rice, lentils, black beans, chickpeas	White bread, white rice, instant flavored oats, crackers
Fruit	Berries, apples, pears, cherries, oranges, kiwi	Fruit juice, canned fruit in syrup, dried fruit with sugar
Dairy	Plain Greek yogurt, cottage cheese, unsweetened milk, cheese	Flavored yogurt, chocolate milk, sweetened creamers
Drinks & snacks	Water, sparkling water, unsweetened tea, nuts, olives	Soda, sports drinks, chips, cookies, granola bars

Protein: The Anchor of Every Meal

Protein is the one thing I never let run out. It keeps me full for hours and has almost no effect on blood sugar, which makes it the anchor of every plate. When you fill your cart, aim for a protein at the center of each meal you are planning.

Reach for chicken breast and thighs, ground turkey, whole eggs, and fatty fish like salmon, which also brings anti-inflammatory omega-3s. Canned tuna and sardines are cheap, shelf-stable, and ready in seconds. If you eat plant-based, tofu, tempeh, and edamame all count.

What I skip: breaded and fried proteins, since the coating is refined carbs, and processed meats like salami, hot dogs, and bacon. The CDC and other health agencies link processed meats to higher chronic disease risk, so I keep those to an occasional thing rather than a staple.

Non-Starchy Vegetables: Fill Half the Cart

If protein is the anchor, vegetables are the volume. Non-starchy vegetables are so low in carbs and so high in fiber that you can eat them freely, and I mean genuinely freely. They fill you up, feed the good bacteria in your gut, and barely register on blood sugar.

Load up on broccoli, spinach, kale, bell peppers, zucchini, cauliflower, green beans, mushrooms, cucumbers, tomatoes, and cabbage. Fresh is great, but frozen is just as nutritious and often cheaper, so I always keep a couple of bags in the freezer for the nights I did not plan ahead.

Starchy vegetables like potatoes, corn, and peas are not off-limits, but they act more like grains, so I treat them as the carb portion of a meal, not a free side. A handful of colorful vegetables at each meal is one of the simplest wins there is. Several of them also show up in my list of foods that lower blood sugar quickly.

Healthy Fats: Slow Everything Down

For years I was scared of fat, and it turns out that was backwards. Healthy fats slow digestion, which means the carbs you eat alongside them hit your bloodstream more gently. Fat also makes food taste good, which keeps this whole thing sustainable.

My cart always has extra-virgin olive oil, avocados, and a rotation of nuts and seeds. Almonds, walnuts, pumpkin seeds, and chia are all great to have on hand. Natural nut butter, the kind where the only ingredient is nuts, is a pantry hero.

What I leave behind: margarine and anything with “partially hydrogenated” oil, plus sweetened nut spreads that are basically candy. Real fats from whole foods are your friend here.

Whole Grains and Legumes: Choose Fiber

Carbs are not the enemy, but the type matters more than almost anything else in your cart. The goal is carbs that come wrapped in fiber, because fiber is what slows the sugar release and keeps you steady.

I buy old-fashioned or steel-cut oats, quinoa, brown rice, barley, and 100 percent whole-grain bread where the first ingredient says “whole.” Legumes deserve a special mention. Lentils, black beans, chickpeas, and kidney beans give you protein and fiber in one package, they are dirt cheap, and canned versions just need a rinse.

What I skip: white bread, white rice, instant flavored oatmeal, and most crackers, since the fiber has been stripped out and the sugar spike comes fast. If you want to see how different grains behave at breakfast, my post on the glycemic index of breakfast foods shows the numbers.

Low-Glycemic Fruit: Yes, You Can Eat Fruit

One of the biggest myths I hear is that people with prediabetes cannot eat fruit. You can. Whole fruit comes with fiber and water that blunt its natural sugar, and the research backs it up. It is fruit juice, not whole fruit, that causes trouble.

My steady picks are berries of every kind, since they are the lowest in sugar and highest in fiber. Apples, pears, cherries, oranges, plums, and kiwi are all solid choices too. I pair fruit with a little protein or fat, like an apple with peanut butter, to keep it even gentler.

What I skip or limit: fruit juice, canned fruit in syrup, and sugary dried fruit, which pack a lot of sugar into a small serving with none of the water to slow it down. A handful of raisins is fine, half a cup of juice is not.

Dairy: Go Plain

Dairy can be a great source of protein, but the sugar hides in the flavored versions. The rule I follow is simple: buy it plain and add your own flavor.

Plain Greek yogurt is my favorite, with double the protein of regular yogurt. Cottage cheese, unsweetened milk, and real cheese in reasonable portions all work well. I sweeten yogurt myself with berries and a sprinkle of cinnamon instead of buying the fruit-on-the-bottom cups, which can hide four teaspoons of added sugar.

What I skip: flavored and “fruit” yogurts, chocolate milk, and sweetened coffee creamers. If you do not do dairy, unsweetened soy milk has a similar protein profile.

The 7 Things I Leave on the Shelf

You do not need to be perfect, but a few items cause the biggest, fastest blood sugar spikes for the least benefit. These are the seven I keep out of my cart almost entirely.

1. Soda. A single can can carry around ten teaspoons of sugar with zero fiber to slow it. This was the hardest one for me and the one that helped the most.
2. Fruit juice. Even “100 percent” juice is concentrated sugar without the fiber of whole fruit. Eat the orange, skip the glass.
3. White bread and bagels. Refined flour behaves a lot like sugar. Choose dense whole-grain loaves instead.
4. Sugary breakfast cereal. Most cereals are dessert dressed up for morning. Check the label and you will be shocked.
5. Ultra-processed snacks. Chips, cookies, and pastries combine refined carbs and unhealthy fats in a way that is easy to overeat.
6. Sweetened yogurt. It looks healthy on the front of the box, but the added sugar tells another story.
7. Processed meats. Hot dogs, salami, and packaged deli meats bring sodium and preservatives without much upside.

Notice I did not say “never.” I still enjoy a treat now and then. But keeping these out of the house means the easy default is the good one, and defaults are what win over months.

How to Read a Nutrition Label

Once you know how to read a label, the marketing on the front of the box stops mattering. I look at three numbers every single time, and it takes about ten seconds.
