About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

ability to provide informed consent

men and postmenopausal women aged 50-64 years

systolic blood pressure < 130 mmHg; diastolic blood pressure < 90 mmHg

Disqualifiers

current use of medications or supplements known to lower blood triglycerides or cholesterol (e.g., fibrates, statins, high dose niacin, high dose omega-3 supplement)

major psychiatric disorder (e.g. schizophrenia, bipolar disorder)

current or past (i.e., last 3 months) use of anti-hypertensive or other cardiovascular-acting medications known to influence vascular function and/or arterial stiffness
