What is DGI?

A Chinese DGI certification system tailored to Chinese diets, beyond the international GI

DGI (Dietary Glycemic Index) is a glycemic index evaluation system developed by the Nutrition and Health Institute of the Chinese Center for Disease Control and Prevention (CDC). Based on the dietary data of the Chinese population, it fits China's eating structure and metabolic characteristics more closely than the international GI standard.

GI Value Classification

LevelGI RangeEffect on Blood GlucoseExample Foods
Low GI< 55Blood glucose rises slowly with small fluctuationsWhole-wheat bread, legumes, nuts
Medium GI55 - 70Moderate rise in blood glucoseBrown rice, sweet potato, corn
High GI> 70Rapid spike in blood glucoseWhite rice, white bread, desserts

All MulanPOP products are formulated with a GI between 25-42, placing them in the low-GI category.

GI vs GL vs Blood Glucose Fluctuation

A scientific explanation of three blood glucose metrics

MetricFull NameMeaningCalculationBest Used For
GIGlycemic IndexRanks how quickly carbohydrates in a food raise blood glucoseGlucose GI = 100 used as the baselineChoosing food types
GLGlycemic LoadCombines GI value with carbohydrate content for a fuller pictureGL = (GI × carbs in grams) / 100Assessing actual post-meal blood glucose effect
Blood Glucose FluctuationThe largest rise in blood glucose after a mealMeasured: post-meal peak − fasting glucosePersonalized glucose management

Why is low GI important? Three everyday benefits of low-GI foods:

  • Steadier blood glucose — avoids sharp post-meal spikes followed by a "sugar crash," reducing large insulin surges
  • Weight management — steadier glucose → longer-lasting satiety → fewer extra snacks → easier weight control
  • Lighter daily routine — a low-GI eating pattern helps keep blood glucose even, making it one sensible choice within a balanced diet

The "Sweet Without Sucrose" Technology

The golden ratio of three natural sugar substitutes

🧊 Erythritol

Zero calories · No effect on blood glucose · Naturally occurring

  • Found naturally in grapes, pears, mushrooms and other foods
  • Only 0.2 kcal/g (5% of sucrose's 4 kcal/g)
  • GI = 0, causes no blood glucose fluctuation
  • Not metabolized by the body; 90% is excreted in urine
  • Cool, clean mouthfeel that pairs well with tea aromas

🍃 Stevia

Plant-derived · 200x sweeter than sugar · Zero calories

  • Extracted from the leaves of the South American stevia plant (Stevia rebaudiana)
  • 200-300x sweeter than sucrose, so only a tiny amount is needed
  • GI = 0, causes no blood glucose fluctuation
  • Used as a sweetener in South America for centuries
  • A faint herbal note that complements tea flavors naturally

🍐 Monk Fruit

Valued in traditional Chinese practice · Naturally antioxidant · Gently soothing

  • Extracted from monk fruit grown in Guilin, Guangxi — a Chinese specialty
  • 150-250x sweeter than sucrose
  • GI = 0, causes no blood glucose fluctuation
  • Rich in mogrosides (Mogroside), with natural antioxidant activity
  • Long valued in traditional Chinese dietary culture for its naturally sweet, refreshing character

The science behind the golden ratio

Each sweetener has a shortcoming when used alone: erythritol is only 70% as sweet as sucrose, so more is needed; stevia carries a slightly bitter herbal aftertaste; monk fruit is the costliest of the three. After 200+ rounds of formulation trials, the MulanPOP R&D team settled on a 5:3:2 golden ratio — a taste closest to sucrose, no unpleasant aftertaste, and cost under control. This ratio has been filed as a national invention patent.

Sweetener Safety: Facts & Myth-busting

Objective insights based on authoritative bodies and scientific journals

🔴 Trending myth: "Does erythritol really cause blood clots?"

In 2023, Nature Medicine published an association study that found individuals with the highest measured blood erythritol concentrations showed a higher rate of cardiovascular events in the cohort. The study raised widespread concern, but it is worth noting:

  • Association ≠ causation: the study found a statistical association but did not prove that erythritol causes blood clots
  • Pre-existing health conditions: participants in the study already carried cardiovascular risk factors
  • Dose matters: high blood concentrations likely reflect heavy intake (>30 g/day), far beyond typical consumption
  • Regulator response: the FDA and EFSA have both stated that the current evidence is insufficient to change their safety assessments of erythritol

MulanPOP's advice: enjoy in moderation (keep daily erythritol intake under 20 g); healthy individuals have no reason for undue concern. Those with existing cardiovascular conditions should consult their physician.

🔴 "Do sugar substitutes make you hungrier?"

This claim is based mainly on the "sweet taste deceives the brain" hypothesis. However, recent randomized controlled trial (RCT) evidence does not support the concern:

  • A 2024 meta-analysis in the American Journal of Clinical Nutrition (58 RCTs, n=13,000+) found that when sugar substitutes replace refined sugar, total energy intake actually decreased
  • Sugar substitutes deliver sweetness without calories, but the "sweetness–energy mismatch" effect varies widely between individuals
  • Pairing them with protein and dietary fiber (as in tea protein bars) helps support satiety
🔴 "Are sugar substitutes harmful in the long term?"

Conclusions from three leading authorities:

  • World Health Organization (WHO, 2023): does not recommend using non-sugar sweeteners for weight control (low-quality evidence), but has not deemed them harmful either; its core advice is to reduce overall sweetness in the diet
  • US FDA: erythritol, steviol glycosides and monk fruit extract are all recognized as GRAS (Generally Recognized As Safe)
  • European Food Safety Authority (EFSA): no acceptable daily intake (ADI) limit has been set for erythritol; stevia's ADI is 4 mg/kg body weight per day

Bottom line: using sugar substitutes in moderation to replace free sugars is widely regarded as safe by mainstream scientific consensus. The key is replacement, not addition.

DGI Health Technology FAQs

What is DGI, and how does it differ from GI?

DGI (Dietary Glycemic Index) is a glycemic index evaluation system developed from the dietary data of the Chinese population and led by the Nutrition and Health Institute of the Chinese CDC. Compared with the international GI, DGI gives more weight to China's staple-food structure (rice-based) and cooking methods (mostly steaming and boiling). The numerical values are similar, but DGI's classification criteria and tested-food database fit Chinese realities more closely. In short: GI is the international standard; DGI is its China-tuned version.

What are the benefits of low-GI foods?

A large body of research points to four benefits of low-GI eating: ① Steadier blood glucose — avoids sharp post-meal spikes and crashes and the resulting surge in insulin; ② Easier weight management — longer-lasting satiety and fewer extra snacks; ③ A heart-friendly pattern — consistent with dietary guidance that supports cardiovascular wellness; ④ Sustained energy — avoids the fatigue and dips in focus that come with blood-glucose crashes. Harvard T.H. Chan School of Public Health recommends favoring low-GI foods in the everyday diet.

What is the GI value of MulanPOP products? Have they been tested?

Every MulanPOP product has its GI measured by third-party laboratories accredited with CMA/CNAS. GI values by range: Tea Protein Bar 25, Tea Chocolate 28, Rock Tea Shortbread 35, Tea Cookies 38, Tea Pastry 42 — all low-GI foods (GI < 55). Test reports can be viewed via the QR code on the packaging or downloaded from our website.

Can people with diabetes enjoy MulanPOP products?

Yes, with a few points to keep in mind: ① start with the lowest-GI options, the Tea Protein Bar (GI=25) or Tea Chocolate (GI=28); ② keep each serving under 30 g; ③ on your first try, check blood glucose two hours after eating to see how your body responds; ④ while MulanPOP contains no added sugar, ingredients such as flour and nuts do contain carbohydrates, so count them toward your daily total; ⑤ when in doubt, consult your physician or dietitian.

Do low-GI snacks really help with weight loss?

The logic behind low-GI snacks and weight management: steadier blood glucose → longer-lasting satiety → fewer extra snacks → lower total energy intake. A 2023 meta-analysis in The BMJ (31 RCTs) found that low-GI diet groups lost more weight on average than control groups (1.5 kg more). One caveat: low GI does not mean low calorie — overeating still adds up. The point is total intake; low-GI snacks help you feel full longer, not eat without consequences.

How does the blood glucose effect of MulanPOP compare with regular desserts?

According to internal testing: after eating equal 50 g portions of MulanPOP Rock Tea Shortbread and a regular cake, the cake pushed post-meal blood glucose to a peak of 8.2 mmol/L (a swing of 3.1), while the shortbread peaked at just 5.6 mmol/L (a swing of 0.6) — a roughly fivefold difference in fluctuation. In other words, MulanPOP's impact on blood glucose is minimal.

How is DGI certification obtained, and is it authoritative?

DGI certification is issued by the Chinese Nutrition Society and relevant authorities. It requires: ① the product's GI measured below 55 by a qualified laboratory; ② a recipe that meets nutritional and health standards; ③ a complete quality-management-system file from the applicant. MulanPOP has earned DGI certification for its core products (certificate numbers are available on our website). The certification is well recognized within China's nutrition and food industries.

Do people with normal blood glucose still benefit from low-GI foods?

Absolutely. Even with normal blood glucose, a long-term high-GI eating pattern is associated with higher long-term health risks. Choosing low-GI foods is a preventive, forward-looking health strategy. What's more, low-GI eating delivers more sustained energy and better focus, avoiding the post-meal energy slump. Whether or not you manage glucose, low-GI eating is the healthier choice.

Can a snack be both low-GI and high-protein?

Absolutely. Protein itself is a near-zero-GI nutrient (GI close to 0). The MulanPOP Tea Protein Bar is a perfect example of "low GI + high protein": a GI of just 25 and 20 g of protein per bar (about the same as two eggs). The combination of protein, low-GI carbs and dietary fiber delivers the most lasting satiety and the most steady, dependable energy.

Are MulanPOP products suitable for keto dieters?

Partially. The Tea Protein Bar and Tea Chocolate ranges are lower in carbohydrates (under 15 g net carbs per 100 g) and can fit within a keto framework. The Rock Tea Shortbread and Tea Pastry ranges contain flour and are higher in carbohydrates (30-45 g net carbs per 100 g), making them less suitable for strict keto. When shopping, check the "carbohydrates — sugars" and "net carbs" figures in the nutrition panel on the back of the packaging.
