The Effects of Healthy Diets With Plant Oils on Heart and Metabolic Health

Purpose

This study will examine the effect of a healthy diet containing cottonseed oil compared to healthy diets containing other commonly consumed plant oils on biomarkers of heart and metabolic health after 4 weeks.

Healthy Diet + Cottonseed Oil (CSOD)
Healthy dietary pattern containing 40g/day/2000 kcal of cottonseed oil (CSO)
  • Other: Healthy Dietary Pattern with Cottonseed Oil
    Cottonseed Oil
Active Comparator
Healthy Diet + Fatty Acid-Matched Plant Oils (FAMD)
Healthy dietary pattern containing 40g/day/2000 kcal of a blend of plant oils comprising a fatty acid profile that matches the CSOD but devoid of CSO

Active Comparator
Healthy Diet + PUFA:SFA Ratio-Matched Plant Oil (P:S-MD)
Healthy dietary pattern containing 40g/day/2000 kcal of plant oil that is lower in polyunsaturated fatty acids (PUFA) and saturated fatty acids (SFA) than the CSOD, but with a matched PUFA:SFA ratio and devoid of CSO.
  • Other: Healthy Dietary Pattern with PUFA:SFA Ratio-Matched Plant Oil
    Plant oil with matched PUFA to SFA ratio

Detailed Description

This is a 3-period randomized crossover complete feeding study examining if a dietary pattern containing cottonseed oil improves lipids/lipoproteins and other cardiometabolic disease risk factors to a greater extent than a fatty acid matched diet devoid of cottonseed oil and a diet lower in polyunsaturated fatty acids (PUFA) and saturated fatty acids (SFA), but with a matched PUFA:SFA ratio
