The drop in blood sugar after drinking this spiced soy drink might come from the sprouts, the spices, or both — the study doesn't prove which part is responsible.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether isolated components (sprouts, ginger, cinnamon, palm sugar, pandan) or their combinations consistently reduce postprandial glucose in type 2 diabetes, enabling comparison of effect sizes.
A systematic review and meta-analysis of all RCTs comparing isolated soybean sprout juice, isolated spice mixtures (ginger+cinnamon+pandan), palm sugar, and the full combination against placebo or plain soy juice, with standardized dosing and 120-minute postprandial glucose as the primary outcome.
Whether soybean sprouts alone, spice additives alone, or their combination each produce different magnitudes of glucose reduction compared to plain soy juice.
A four-arm double-blind RCT with 120 adults with type 2 diabetes: (1) plain soy juice, (2) soybean sprout juice (no spices), (3) spice-infused plain soy juice (no sprouts), (4) full spiced sprout juice. All beverages matched for calories, volume, and sweetness. Blood glucose measured at 0, 60, 120 minutes after consumption over 8 weeks.
Whether habitual consumption of sprout-only, spice-only, or combined beverages predicts different trajectories of glycemic control over time.
A prospective cohort study following 400 adults with type 2 diabetes for 18 months, categorizing them by primary beverage consumed: plain soy, sprout-only, spice-only, or full combination, with quarterly HbA1c and postprandial glucose measurements, adjusting for medication and diet.
Whether individuals with the greatest glucose reductions are more likely to have consumed the full combination versus single components.
A case-control study comparing 80 adults with type 2 diabetes who achieved >30 mg/dL postprandial glucose reduction after 4 weeks to 80 with <10 mg/dL reduction, matched for baseline glucose and medication, assessing prior consumption patterns of each component.
Whether current consumers of each beverage component show different average postprandial glucose levels at a single time point.
A cross-sectional survey of 600 adults with type 2 diabetes measuring current consumption frequency of sprout juice, spice-infused soy, palm sugar, etc., and concurrent 120-minute postprandial glucose levels, adjusting for age, BMI, and medication.
