Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Average American Diet With SoFAS Replaced With Avocado

Average American Diet

Arm Description

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).

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