INTERVENTIONAL
Conditions
Summary
This study will implement a Western Diet (WD) to understand cardiometabolic and immune function in middle-aged adults (50- 64 years old). Vascular health, intestinal permeability, and T-cell function will be examined before, during, and after the WD. The WD is a 10-day diet and will consist of 25% of total energy from added sugars.

- heavy alcohol consumption (≥8 drinks/week for women and ≥15 drinks/week for men)
- recent major change in health status within the previous 6 months (i.e., surgery, significant infection, or illness)
- current smoking within the past 3 months.
