Research Subject Recruitment

Sparkling water study

The Saliva, Perception, Ingestion, and Tongues Lab in the Department of Nutrition Science is recruiting participants for its sparkling water study. In this experiment, researchers will give participants flavored, unsweetened sparkling waters to drink for two weeks. During those weeks, they will have three taste tests with some sodas and sparkling water products. Participants will be asked questions about their beverage consumption at the beginning, middle and end of the tests. Researchers also will follow up with participants about their beverage consumption two weeks after the experiment is over.

To be eligible for the study, individuals must:

  • Be between 18 to 45 years old.
  • Consume a minimum amount of sugar-sweetened sodas on a regular basis.
  • Be willing to drink unsweetened, flavored sparkling waters.
  • Not be dieting/changing their diet and agree to maintain their current diet for at least days one through 15 of the study.
  • Willing to complete all study activities.
  • Have access to a computer, phone or smart device with internet to access the online sensory tests and survey.

If any of the criteria below apply, individuals cannot participate in the study:

  • Are under the care of a medical professional or taking medication for prediabetes, Type 1 diabetes or Type 2 diabetes.
  • Are dieting or attempting to lose weight.
  • Have food allergies or dietary restrictions for any of the ingredients included in the study.

Individuals can earn up to $30 in Amazon gift cards for their participation. Those interested in participating in the study should take the screening survey. For more information, email Vinnie Valicente at vvalicen@purdue.edu. IRB-2022-164.

 

Mediterranean diet and mushroom nutrition study

This research study is assessing the effects of including mushrooms as part of a healthy eating pattern on indices of perceived mental health/anxiety/depression along with risk factors for cardiovascular disease and Type 2 diabetes.

The study seeks men and women who are willing to consume a Mediterranean-style diet for eight weeks either with or without mushrooms. All food will be provided. Participants are required to attend three study visits at the research site over approximately a three-month period. Individuals will be compensated $300 for participating in the study.

Interested subjects should be age 30 to 69, overweight yet in general good health, nonsmokers and nonpregnant. Those interested in participating in the study should contact Cassi Uffelman at cuffelma@purdue.edu and mention the “Mediterranean Diet and Mushroom Study."

The study adheres to all required COVID-19 standard operating procedures. For more information regarding the standard operating procedures, visit https://protect.purdue.edu.

The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science. IRB#: IRB-2019-650.

 

MEAL-DM study

The purposes of this study are testing the Monitoring Eating And Lifestyle for Diabetes Management (MEAL-DM) app, which was created to record the foods someone eats or beverages someone drinks in a day, and then completing traditional online dietary surveys asking about meals and snacks that participants ate and drank over the same period of time that participants completed the MEAL-DM.

Participants must be 18-65 years old, use insulin and be fluent in English. Participants may become more aware of their diet and overall health, and develop healthy eating habits. The study will take around a week to complete, and participants will receive up to a $40 gift card for compensation.

The research study will be conducted at the participants’ preferred locations. To see if you are eligible for this study, take the screening survey or contact Yue Qin at qin53@purdue.edu. The principal investigator is Heather Eicher-Miller, associate professor of nutrition science. IRB-2021-1734.

 

Almonds and diabetes risk

Participants are needed by the Department of Nutrition Science to study the effect of almonds on blood sugar concentrations.

Individuals may be eligible to participate if they are age 18-70, have high blood sugar levels and have no allergy to almonds. Participants may earn up to $600 in 16 weeks. The principal investigator for the study is Richard Mattes, Distinguished Professor of Nutrition Science.

Study on effects of consuming different proportions of red meat and plant-based, protein-rich foods

This research study is assessing the effects of consuming different proportions of red meat and plant-based, protein-rich foods (nuts, seeds, and soy products) incorporated into a U.S. healthy eating pattern on cardiovascular disease risk factors in adults at high risk of developing a heart-related disease.

The study seeks men and women who are willing to consume a U.S. healthy eating pattern with varying proportions of red meat and plant-based, protein-rich foods for 10 weeks. All food will be provided. Participants are required to attend four study visits at the research site over approximately a three and a half month period. Individuals will be compensated $300 for participating in the study.

Interested subjects should be age 30 to 69, overweight, nonsmokers and nonpregnant. Those interested in participating in the study should contact Harrison Cottingham at hcotting@purdue.edu and mention the “US healthy eating pattern plant-based and animal protein."

Study on probiotics and lactose intolerance symptoms

The Department of Nutrition Science is conducting a study to see how probiotics impact lactose intolerance symptoms.

Participants must be healthy, nonsmoking, age 18-65, and not allergic to milk but believe they are lactose-intolerant. Other criteria for study participation apply.

This study will consist of a screening day and two testing days approximately 14 days apart. Participants will be required to come to Stone Hall for approximately two consecutive hours on the screening day and eight hours for each testing day.  Participants also will be asked to track any symptoms related to lactose intolerance for two weeks following their last testing day. Participants will receive up to $200 for completing the study.
