Summary

This study aims to investigate the effects of RT-90 resistant cassava starch on glycemic control using a human dietary trial and to evaluate its potential as a prebiotic fiber supplement. This study will assess the efficacy of RT-90 resistant cassava starch in improving glycemic control, body composition, and gut microbiome in healthy individuals.

  • Resistant Starch
  • Tapioca Starch
  • Prebiotic Fiber

Interventions

DIETARY_SUPPLEMENT

RT-90 resistant tapioca starch

Within 5 minutes, consume resistant starch containing 50 g of total carbohydrates (total product weight 57 g), dissolved in 250 mL of water, and perform an oral glucose tolerance test to monitor blood sugar changes. After the test, the two groups will switch and consume resistant starch or glucose powder again after at least 1 week.

DIETARY_SUPPLEMENT

control group

The subjects were asked to take a 50 g glucose powder dissolved in 250 mL of water within 5 minutes to conduct an oral glucose tolerance test to monitor blood sugar changes. After the test, the subjects were asked to empty their stomachs at least 1 week after the test and then switch to take RT-90 resistant starch or glucose powder again.

DIETARY_SUPPLEMENT

Commercially available resistant starch

The dosage is calculated at 0.5 grams per kilogram of adult body weight (e.g., a 60-kilogram adult would need to take 30 grams). Participants should dissolve the test product in water and drink it on an empty stomach before their first meal each day, continuing for 12 weeks.
