Hypothesis
Does onion extract reduce postprandial blood glucose spikes by inhibiting intestinal α-glucosidases?
Conclusion
Onion extract significantly lowers postprandial blood glucose levels in rats by inhibiting intestinal sucrase activity.
Supporting Evidence
- Onion extract significantly reduced blood glucose spikes after sucrose loading in rats.
- The inhibitory activity of onion extract on sucrase was confirmed in both in vitro and in vivo studies.
- Quercetin, a major component of onion, showed strong inhibitory effects on α-glucosidases.
Takeaway
Onion extract can help keep your blood sugar from getting too high after eating by slowing down how fast your body absorbs sugar.
Methodology
The study involved in vitro and in vivo experiments using Sprague-Dawley rats to assess the effects of onion extract on blood glucose levels and intestinal enzyme activities.
Limitations
The study was conducted on rats, and further clinical trials are needed to confirm the effects in humans.
Participant Demographics
