简要总结
This study is investigating the benefits of lean beef consumption on cardiometabolic health and gut microbiome.
详细描述
The study is a 6-wk randomized, controlled, and parallel arm clinical trial. Participants will be randomized to consume either lean grain-fed beef, lean grass-fed beef, or plant-based meat for 6 weeks. Outcomes assessed will include metabolic, inflammatory, and gut microbiome markers.

研究组 & 干预措施
Lean (≥90%) Grass-Fed Beef
The quantity of beef will be adjusted or normalized based on their individual energy requirements. The specified amount will be 4 oz. per day or 28 ounces per week for participants with an energy requirement of 2000 kcal. Participants will consume meals for six weeks.
干预措施: Lean (≥90%) Grass-Fed Beef (Other)
Lean (≥90%) Grain-Fed Beef
The quantity of beef will be adjusted or normalized based on their individual energy requirements. The specified amount will be 4 oz. per day or 28 ounces per week for participants with an energy requirement of 2000 kcal. Participants will consume meals for six weeks.
干预措施: Lean (≥90%) Grain-Fed Beef (Other)
Plant-Based Meat
Plant-based meat (beyond meat product) would be macronutrient matched to the same quantities of meat prescribed for a given energy level. Participants will consume meals for six weeks.
