简要总结

This randomized study will be conducted to compare the effect of a healthy beef-centric diet to a healthy U.S.-style dietary pattern on inflammation and other metabolic health outcomes in a metabolic syndrome and/or pre-diabetic population.

详细描述

This study follows a randomized, open-label, parallel design to compare the effects of a healthy beef-centric diet to a healthy U.S.-style dietary pattern on inflammation and other metabolic health outcomes in a metabolic syndrome and/or pre-diabetic population.

The comparator diet in this study is a U.S. Department of Agriculture (USDA) Healthy U.S.-Style Dietary Pattern, as outlined in the 2020 Dietary Guidelines for Americans, which emphasizes the consumption of nutrient-dense foods across all food groups in recommended amounts. This includes a variety of vegetables, fruits, whole grains, low-fat dairy, lean protein sources, and healthy oils, while limiting added sugars, saturated fats, and sodium.

The test diet in this study involves a healthy beef-centric diet, where beef is the main source of protein. Participants will consume 70% of their daily energy intake from beef. The rest of their calories will come from other protein and fat sources (20%), along with a small amount (10%) from low-carbohydrate fruits (such as berries) and vegetables (like dark leafy greens). This diet excludes all grains. While the carbohydrate intake is low, it is slightly higher than that of a typical ketogenic diet.

The healthy beef-centric diet is being investigated for its effects on metabolic health after a 5 week intervention period. This study will investigate whether a beef-centric diet will support management of glycemic control, inflammation, and lipid-related risk factors, while also enhancing quality of life.
