1Basic Principles of Diabetic Diet

The core goal of diabetic diet management is to control post-meal blood sugar smoothly through reasonable food combinations, avoid large glucose fluctuations, and ensure balanced nutrition. This doesn't mean giving up delicious food entirely—it's about learning to choose and combine foods scientifically.

Basic principles include: controlling total calorie intake and maintaining a healthy weight; choosing low glycemic index (GI) foods; increasing dietary fiber intake; reasonably distributing calories across three meals; paying attention to eating order; limiting added sugars and saturated fats.

2Glycemic Index (GI) and Glycemic Load (GL)

Glycemic Index (GI) measures how quickly carbohydrates in food raise blood sugar. GI ≤ 55 is low-GI, 56-69 is medium-GI, and ≥ 70 is high-GI.

But GI only reflects carbohydrate 'quality,' not 'quantity.' Glycemic Load (GL) considers both quality and quantity, calculated as: GL = GI × digestible carbs per serving (g) ÷ 100. GL ≤ 10 is low, 11-19 is medium, and ≥ 20 is high.

For example, watermelon has a high GI (72), but because it's mostly water, a 100g serving has GL of only 4, which is low. White rice has GI of 83, and a bowl (150g) has GL of 43, which is high.

3Recommended Foods

The following foods have minimal impact on blood sugar and are suitable for daily consumption by people with diabetes:

✅ Recommended Foods

Whole grains: oats, brown rice, whole wheat bread, quinoa
Legumes: black beans, red beans, chickpeas, lentils
Vegetables: broccoli, spinach, celery, cucumber, tomato
Low-GI fruits: apples, pears, strawberries, blueberries, grapefruit
Quality protein: fish, chicken breast, tofu, eggs
Healthy fats: olive oil, avocado, nuts (in moderation)

⚠️ Foods to Limit

Refined carbs: white rice, white flour, white bread, pastries
Sugary drinks: soda, fruit juice, milk tea, sports drinks
High-sugar fruits: lychee, longan, banana, durian, grapes
Processed foods: chips, cookies, instant noodles, sausages
Fried foods: fried chicken, french fries, fried dough sticks
High-fat meats: fatty meat, pork belly, processed meat products

4The Plate Method: How to Build Every Meal

The plate method is a simple, intuitive way to structure meals by dividing your plate into four sections:

1/2 Plate: Non-starchy vegetables (broccoli, spinach, cucumber, tomato, etc.). Vegetables are rich in dietary fiber, which slows gastric emptying and reduces post-meal glucose rise.
1/4 Plate: Quality protein (fish, chicken breast, tofu, eggs, etc.). Protein increases satiety, reduces total calorie intake, and has minimal direct impact on blood sugar.
1/4 Plate: Whole grains or starchy vegetables (brown rice, oats, sweet potato, corn, etc.). Choose low-GI carbohydrate sources and control portions.
Beverages: Choose water, light tea, or unsweetened coffee. Avoid sugary drinks and juice.

💡 Eating order matters too: eat vegetables first, then protein, and finally carbohydrates. This uses vegetables and fiber to delay carbohydrate absorption and lower post-meal glucose peaks.

5Pre/Post-Meal Glucose Pairing Analysis

glucose index is one of SugarLite's core features. By pairing pre- and post-meal glucose readings, it helps you understand how different foods truly affect your personal blood sugar.

How it works: Measure and log pre-meal glucose (baseline) before eating, then measure again 2 hours after the meal. SugarLite automatically calculates the glucose change (Δ = post-meal - pre-meal) and marks the food's impact level based on the magnitude of change.

Δ < 2.0 mmol/L: Friendly food—prioritize these.

Δ 2.0-3.9 mmol/L: Moderate impact food—consume in moderation.

Δ ≥ 4.0 mmol/L: High-risk food—limit or avoid.

Through multiple records, SugarLite builds your personal food glucose response database and intelligently recommends dietary plans tailored to you.

6Tips for Eating Out

Eating out is a common challenge for people with diabetes. These tips can help you better control blood sugar:

Plan ahead: Check the restaurant menu and choose dishes with vegetables, quality protein, and low-GI staples.
Control portions: Restaurant portions are often large. Ask for smaller portions or share with others.
Choose cooking methods: Prioritize steamed, boiled, grilled, or stewed dishes. Avoid fried and braised options.
Watch for hidden sugars: Many dishes (sweet and sour pork, fish-flavored shredded pork) contain large amounts of added sugar—choose carefully.
Adjust eating order: Even when dining out, try to eat vegetables first, then protein, and finally staples.
Carry a glucometer: Monitor blood sugar anytime when eating out and adjust your strategy accordingly.

7Using SugarLite to Log Diet and Glucose Response

SugarLite's food logging feature makes blood sugar management simple and efficient:

Quick Logging: Take a photo or search the food database to log each meal with one tap.

Automatic Calculation: Built-in rich food database automatically calculates carbs, calories, and estimated GI values.

Glucose Index Pairing: Automatically links pre- and post-meal glucose records to generate personalized food glucose response reports.

Smart Recommendations: Based on your historical data, recommend recipes and food combinations suitable for you.

Trend Analysis: View the correlation between diet and blood sugar trends to discover hidden dietary patterns.
