Human Nutrition Laboratory

Our research is aimed at addressing metabolic and satiety hormone responses to different nutrients, diets and/or exercise. We are currently studying the effects of dietary fatty acid composition in meals and diets on postprandial energy expenditure, fuel utilization, and markers of hunger and satiety. We also study how nutrients, diets, and supplements impact health and athletic performance.

    Description:

    Overall Goal: The overall goal of this study is to test the impact of a diet rich in CSO against a diet rich in OO to determine if the CSO diet will show greater improvements in blood cholesterol profiles and lipid metabolism in adults with hypercholesterolemia.

    Study Design: Single-blind, randomized, control trial in humans

    Participants: 64 men and postmenopausal women between the ages of 50-75 with high cholesterol levels

    Data Collected: Anthropometrics, body composition, lipid profile, glucose and insulin responses, appetite and satiety, sensory evaluation, metabolism, coagulation, and inflammation.

    Description:

    Overall Goal: The overall goal of this study is to test the impact of daily consumption of pecans versus a nut-free diet on blood lipid profiles and lipid metabolism in adults with bigger builds or hypercholesterolemia.

    Study Design: Single-blind, randomized, control trial in humans

    Participants: 114 men and postmenopausal women between the ages of 30-75 with high cholesterol levels or a BMI greater than 28 kg/m2

    Data Collected: Anthropometrics, body composition, lipid profile, glucose and insulin responses, appetite and satiety, sensory evaluation, antioxidants, metabolism, and inflammation.

    Betsy Cogan

    Description:

    Overall Goal: The overall goal of this study is to examine mechanisms leading to cephalic phase response dampening and subsequent appetite following a mouth rinse containing energy, sweet taste, or energy+sweet taste in normal weight or obese adults. 

    Study Design: Double-blind, randomized, control trial in humans 

    Participants: 40 men and women between the ages of 18-45 who are categorized as either normal weight or obese based on body mass index (BMI) or body fat percentage (bf%).

    Data Collected: Anthropometrics, taste bud quanitity, taste preference, diet quality and dietary pattern, stress and anxiety, body composition, glucose and insulin responses, appetite and satiety,  and sensory evaluation.

  • Investigators:
    Jamie Cooper
    Megan Houston

    Description:

    Overall Goal: The purpose of this study is to determine whether frequent self weighing is associated with a healthy BMI, higher physical activity levels, and less chronic disease risk compared to those who weigh less frequently in the U.S. public.  

    Study Design: Anonymous convenience sample in humans

    Participants: Approximately 500 adults between the ages of 18-75 who live in the U.S., speak English, and have access to the internet.

    Data Collected: All participants complete an online questionnaire about 115 questions assessing frequency of self-weighing, weight management, dietary and physical activity characteristics, and lifestyle factors. The questionnaire takes about 20 minutes to complete.

    Description:

    Overall Goal: The purpose of this study is to determine whether caffeine mouth rinses improve the time to complete a 12.8K run (approximately 1 hour of endurance exercise) more than a placebo mouth rinse. We also will determine whether there is a synergistic effect of a caffeine plus carbohydrate mouth rinse.

    Study Design: Randomized, double-blind, crossover design in humans

    Participants: 32 normal weight adults between the ages of 18-45 who train in aerobic exercise at least 4 days per week for at least 1 hour per day

    Data Collected: Anthropometrics, heart rate, rate of perceived exertion, completion times, satiety and thirst levels, sensory evaluations between the four different mouth rinses

    Description:

    Overall Goal: We are interested to investigate how the holiday season (November- January) affects general health status, especially stress and stress-related measures in the body such as your perceived stress level, blood pressure, sleep patterns, body shape/weight, and a number of conceptual perceptions about food.

    Study Design: Single-blinded, randomized, control trial in humans

    Participants: 300 normal weight, overweight or obese adults between the ages of 18-70

    Data Collected: Anthropometrics, lipid profile, glucose and insulin responses, Questionnaires include: Drive for Objective Thinness (DFOT), Perceived Stress Scale (PSS), Three factor Eating Questionnaire (TFEQ), Power of Food Scale, sleep questionnaire, self-weighing frequency scale and Fat Preference Questionnaire, Mindful eating factors, Stages and processes of change in weight management.

    Description:

    Overall Goal: The purpose of the study is to look at the effects of different types of walnuts in a breakfast muffin on markers of health. Those markers of health include cholesterol profiles, blood sugar responses, and antioxidant levels in the body after different breakfast muffin meals. 

    Study Design: Double-blinded, randomized, cross-over 

    Participants: 30 normal weight adults between the ages of 18-45 

    Data Collected: Anthropometrics, lipid profile, glucose and insulin responses, satiety, sensory evaluations and antioxidant levels between the muffins with English walnuts, black walnuts, and no walnuts from fasting to 3 hours post prandial.

  • Investigators:
    Jamie Cooper
    Alexis Marquardt

    Description: 

    Overall Goal: The purpose of this study to test the impact of the traditional high-fat, high sugar breakfast muffin against a pecan-containing muffin to determine if the pecans will mitigate the post-meal increases in glucose, insulin, and lipids, while increasing plasma antioxidant levels and appetite.

    Study Design: Double-blind, randomized, control in humans

    Participants: 30 normal weight adults between the ages of 18-45

    Data Collected: Anthropometrics, lipid profile, glucose and insulin responses, satiety, sensory evaluations and antioxidant levels between the muffin without pecans and the muffin with pecans from fasting to 3 hours post prandial.
