Summary

The purpose of this study is to assess the effects of replacing starchy vegetables and refined grains with beef in a vegetarian diet on cardio-metabolic disease risk factors in adults in a cross-over, randomized controlled feeding trial.

Detailed description

The purpose of this study is to assess the effects of replacing starchy vegetables and refined grains with beef in a vegetarian diet on cardio-metabolic disease risk factors in adults in a cross-over, randomized controlled feeding trial. The hypothesis is that isocalorically replacing predominantly starchy vegetables and refined grains with 6 oz. of beef/day will enhance improvements in cardiometabolic disease risk factors, particularly atherosclerotic-promoting lipids and lipoproteins. It is also hypothesized that participant satisfaction and acceptance of a healthy eating pattern with 6 oz. of beef per day will be higher compared to without beef.

Conditions

• Diet Modification

Interventions

Type	Name	Description
OTHER	Controlled healthy vegetarian diet	The controlled healthy vegetarian diet will follow the Dietary Guidelines for American's recommendations. All foods and beverages will be provided during intervention to achieve the desired eating pattern.
OTHER	Controlled beef diet	The controlled beef diet will incorporate various cuts of lean unprocessed red meat into the healthy vegetarian eating pattern, as approved by the American Heart Association's Food Certification Program. The beef diet will isocalorically replace starchy vegetables and/or refined grains with 6 oz. of beef/day for five weeks.
