Completed · Not applicable

Conditions studied: Elevated Triglycerides, Hypertriglyceridemia

In brief

The objective of this study is to assess the effects of replacing energy from SoFAS with energy from avocado on non-high-density lipoprotein cholesterol (non-HDL-C) and other aspects of the cardiometabolic health profile including fasting lipoprotein lipid and particle concentrations, insulin sensitivity and blood pressure in men and women with elevated triglycerides (TG).
