ClinConnect Summary

This clinical trial is studying the effects of Hass avocados on blood sugar control in people with type 2 diabetes. Researchers believe that eating avocados may help lower fasting blood sugar levels compared to eating an equal amount of other fruits. The trial is currently looking for participants aged 18 to 65 who have been diagnosed with type 2 diabetes and have specific blood sugar levels. To join, participants should be stable on their diabetes medications for at least three months and be willing to follow the study's guidelines, including having blood tests.

If you decide to participate, you will be provided with avocados and other foods as part of a controlled diet to see how they affect your blood sugar. It's important to note that not everyone can join this study; for example, individuals with certain health conditions or who have recently lost a significant amount of weight may be excluded. This trial could be an exciting opportunity to contribute to research that may help improve diabetes care.
