Trial Summary

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What evidence supports the effectiveness of the treatment Maltodextrin, Maltodextrin powder, Dextrin, Maltodextrin DE, Super Starch for managing Type 1 Diabetes?

Research shows that resistant maltodextrin can lower blood sugar and insulin levels after meals in healthy people, which might help manage blood sugar in those with diabetes. Additionally, diets high in slowly digestible starch have been shown to improve blood sugar control in people with Type 2 Diabetes, suggesting potential benefits for Type 1 Diabetes as well.12345

Is maltodextrin safe for human consumption?

Research indicates that maltodextrin is generally safe for human consumption, with no significant adverse effects on gastrointestinal symptoms reported in healthy adults. However, high doses may cause flatulence, and its rapid absorption can lead to increased blood sugar levels, which may be less desirable for health.13567

How does the treatment of slow digestible carbohydrates differ from other treatments for type 1 diabetes?

Slow digestible carbohydrates, like the SUSTRA™ 2434 blend of tapioca flour and corn starch, provide a unique approach by releasing glucose slowly and steadily, which helps maintain balanced blood sugar levels over time. This is different from other treatments that may cause rapid spikes and drops in blood sugar, offering a more stable energy release and potentially improving glycemic control without adverse gastrointestinal effects.3891011

What is the purpose of this trial?

In this within-subject cross-over study, the investigators hypothesize that corn-starch based supplements taken prior to exercise will decrease the risk of delayed hypoglycemia in adolescents with T1D, improve performance during exercise, and decrease glycemic variability during exercise.

Interventions

  • Maltodextrin
  • Super Starch
Trial Overview The study is testing if corn-starch based supplements (maltodextrin and super starch) taken before exercise can help prevent low blood sugar afterwards, improve workout performance, and stabilize blood sugar levels during physical activity in young people with Type 1 Diabetes.

Findings from Research

In a study involving 18 participants (12 with diabetes and 6 nondiabetic), hydrogenated starch hydrolysates (HSHs) produced a lower post-meal glycemic response compared to glucose, indicating they may be a better option for managing blood sugar levels.
Among the HSHs tested, HSH 6075 resulted in a higher glycemic response than HSH 5875, suggesting that the type of HSH can influence carbohydrate absorption and glycemic impact.

The SUSTRA™ 2434 slowly digestible carbohydrate, made from tapioca flour and corn starch, showed a high slowly digestible fraction of 51% in vitro, indicating its potential for providing sustained energy.
In a study with 14 healthy adults, consuming foods containing this slowly digestible starch resulted in a lower glycemic index and a balanced release of energy, with lower blood glucose levels at 30-60 minutes and higher levels at 120-240 minutes post-consumption.
