If you’re managing diabetes, prediabetes, or insulin resistance, chances are you’ve heard of the glycemic index (GI). It’s a useful tool that ranks how quickly certain foods raise your blood sugar, and it can make a major difference in how you feel after meals.
At Reach7 Diabetes Studios, we teach patients how to use the glycemic index in a real-world, sustainable way. No complicated math. No extreme dieting. Just smart swaps that help reduce blood sugar spikes, curb cravings, and improve long-term health.
But the question we hear most is: “So… what exactly should I buy at the store?”
Let’s try to simplify that.
🔍 What Is the Glycemic Index, Really?
The glycemic index (GI) ranks carbohydrates on a scale of 0 to 100, based on how much they raise your blood sugar after eating.
Low-GI foods (55 or less): Gentle on blood sugar
Medium-GI foods (56–69): Moderate effect
High-GI foods (70+): Sharp spikes and crashes
Focusing on low- and moderate-GI foods helps you:
✅ Stay fuller, longer
✅ Avoid energy dips
✅ Support A1c and fasting glucose improvements
✅ Reduce risk of long-term complications
✅ Low-Glycemic Grocery List Essentials
Here’s what to prioritize across your next grocery haul:
🥦 Non-Starchy Vegetables (Naturally Low GI)
Leafy greens: spinach, kale, romaine
Broccoli, cauliflower, Brussels sprouts
Bell peppers, zucchini, mushrooms, tomatoes
Cucumbers, green beans, celery, cabbage
💡 Pro Tip: Fresh or frozen is fine, just watch out for the added sauces and dressings.
🍓 Fruits (Yes, You Can Eat Fruit)
Berries: strawberries, blueberries, raspberries
Apples and pears (eat the skin!)
Oranges, grapefruit (in moderation)
Kiwis, cherries, plums
🚫 Avoid fruit juices and dried fruits; they’re concentrated sugar bombs.
🍞 Whole Grains (Look for Fiber First)
Steel-cut oats
Quinoa
Barley
Brown or wild rice
Sprouted or 100% whole-grain bread (e.g. Ezekiel bread)
✅ Look for at least 3g of fiber per serving to slow sugar release.
🫘 Legumes & Plant Proteins
Lentils, chickpeas, black beans
Edamame, tofu, or tempeh
These are low GI + high in fiber and protein—a triple win for blood sugar.
🍗 Lean Proteins (Balance Your Plate)
Skinless chicken or turkey
Salmon, tuna, or sardines (omega-3 bonus)
Eggs
Greek yogurt (unsweetened)
Lean beef or pork (in moderation)
🧠 Protein helps blunt the blood sugar effect of carbs.
🥑 Healthy Fats (Don’t Fear These)
Avocados
Extra virgin olive oil
Almonds, walnuts, chia seeds, flaxseed
Natural nut butters (no sugar added)
These fats improve satiety and support insulin sensitivity.
🧂 Pantry & Extras
Spices: cinnamon, turmeric, garlic
Vinegars: especially apple cider vinegar
Low-sodium broth
Unsweetened almond, cashew, or soy milk
Dark chocolate (70%+ cocoa, in small amounts)
⚠️ High-GI Foods to Limit
White bread, white rice, pasta, instant oats
Sugary cereals, pastries, and crackers
Soda, fruit juice, sweetened teas
Chips, candy, baked goods
Most “fat-free” or “diet” snacks (often loaded with sugar)
