Men and women who smoke regularly
Documented vascular disease

Summary

This trial will study how strawberries can help improve immune and vascular systems to reduce inflammation, improve endothelial function & insulin sensitivity.

Who is the study for?
This trial is for individuals with prediabetes who may have insulin sensitivity issues, inflammation, or are at risk of developing diabetes. Participants should not have any allergies to strawberries and must be willing to consume strawberry powder or a control powder daily.
What is being tested?
The study tests the effects of different doses of freeze-dried whole strawberry powder (12g and 36g) versus a control (0g), on immune and vascular health over four weeks. It measures how strawberries might improve inflammation markers, blood sugar regulation, and oxidative stress defense.
What are the potential side effects?
Potential side effects from consuming high doses of strawberry powder could include allergic reactions in sensitive individuals or gastrointestinal discomfort. However, strawberries are generally considered safe with minimal risks when consumed as part of a regular diet.
