Metabolic Effects of Replacing Dietary Refined Carbohydrate With a Combination of Egg Protein and Unsaturated Fats in Men and Women With Elevated Triglycerides
The goal of this study is to evaluate the effects of replacing some refined starches and added sugars with a combination of egg protein and unsaturated fatty acids on markers of cardiometabolic health in men and women with hypertriglyceridemia.

Descripción detallada
The objective of this study is to evaluate the effects of a combination of egg protein and unsaturated fatty acids acting as substitutes for ~16% of energy from refined carbohydrate on the metabolic profile of men and women with elevated triglycerides.
This is a randomized, controlled feeding, crossover trial that includes two screening/baseline visits, two 3-week treatment conditions, and a 2-week washout phase.
Subjects consume a standardized background diet (7-day rotating menu) that incorporates at least 3 servings/day of study test foods, providing 40-60% of subjects' daily energy needs.
Study test foods consist of yogurt, muffins, waffles, and cookies.
The test foods account for 8% higher protein energy (from egg protein) and 8% higher fat energy (from unsaturated fatty acids) in the Active Condition compared to the Control Condition.
In the Control Condition, the study foods account for 16% higher carbohydrate energy.
The overall macronutrient composition of each condition is as follows: Active Condition, approximately 42/23/35% kcal from carbohydrate/protein/fat, respectively, and Control Condition, approximately 58/15/27% kcal from carbohydrate/protein/fat, respectively.
Blood samples will be collected at baseline and end of treatment for measurement of metabolic parameters, and a liquid meal tolerance test (LMTT) will be conducted at baseline and the end of each treatment period.
