NCT04990817

Brief Summary

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).

Study Arms (2)

Average American Diet With SoFAS Replaced With Avocado

EXPERIMENTAL

Average American diet with foods that provide the equivalent of 1 medium to large avocado per day. It is anticipated that energy from avocado would replace 12-15% of daily energy, roughly half from solid fats and half from added sugars (SoFAS).

PLACEBO COMPARATOR

Average American diet based on macronutrient analyses from the most recent Nutrition and Health Examination Survey.
