This trial studies how well a group of compounds found in blueberries called anthocyanins are absorbed into the body from 2 different types of blueberry confections (blueberry extract and whole blueberry powder). Blueberries contain several compounds which may be beneficial for human health and prevention of disease. These compounds can be consumed as part of a complex matrix in the whole fruit or also in a simplified matrix in the form of a fruit extract. Studying the absorption and metabolism of these compounds may help researchers understand how they influence health and disease, as well as determining the role of the food matrix on absorption of berry phytochemical.

Lower attainment of cardiovascular health (CVH), indicated by the American Heart Association's Life's Simple 7 (LS7; physical activity, diet, cholesterol, blood pressure, body mass index, smoking, glycemia) and Life's Essential 8 (LE8; LS7+sleep) metrics, is a major contributor to Black men having the shortest life-expectancy of any non-indigenous race/sex group. Unfortunately, a paucity of literature exists on interventions aimed at improving CVH among Black men. The team of clinician scientists and community partners co-developed a community-based lifestyle intervention titled Black Impact: a 24-week intervention for Black men with less-than-ideal CVH (\<4 LS7 metrics in the ideal range) with 45 minutes of weekly physical activity, 45 minutes of weekly health education, and engagement with a health coach, group fitness trainer, and community health worker. Single-arm pilot testing of the intervention (n=74) revealed high feasibility, acceptability, and retention and a 0.93 (95% confidence interval: 0.40, 1.46, p\<0.001) point increase in LS7 score at 24 weeks. Secondary outcomes included improvements in psychosocial stress (i.e., perceived stress, depressive symptoms), patient activation, and social needs. Thus, robustly powered clinical trials are needed to determine the efficacy of Black Impact and to evaluate the underlying interpersonal and molecular pathways by which Black Impact improves psychosocial stress and CVH. Thus, the investigators propose a randomized, wait-list controlled trial of Black Impact. This novel, community-based intervention to provide a scalable model to improve CVH and psychosocial stress at the population level and evaluate the biological underpinnings by which the intervention mitigates cardiovascular disease risk. The proposed study aligns with American Heart Association's commitment to addressing CVH equity through innovative, multi-modal solutions.

This clinical trial tests whether a new dietary pattern that consists of foods that lower the blood insulin response can reduce breast cancer risk in high-risk women. In a large group of patients, this new dietary pattern was associated with reduced risk of multiple cancers and reduced risk of long-term weight gain. Parts of this new dietary pattern are quite different from typical dietary recommendations, and much education is needed. Overall, compared to the typical American diet, this new dietary pattern is moderately low in total fat and saturated fat, low in protein from animal foods but high in protein from plant sources, high in fruits and vegetables, high in whole grains, and high in dietary fiber. We will determine if a low-insulinemic dietary pattern intervention is feasible and effective in reducing breast cancer risk in high-risk women.

Sleep deprivation is a major problem in military populations. Some major consequences of sleep loss are inability to concentrate, poor work efficiency, and increase in errors during daily tasks. Ketogenic supplementation is speculated to alleviate some sleep deprivation issues via action of ketones. Ketones are small molecules that appear in the blood when following a ketogenic diet or consuming ketone supplements. The goal of this project is to find out if diet and/or ketones can improve sleep deprivation detriments over 5 days of sleep restriction (-50% from habitual sleep).

Covid-19 is an additional stressor Black women have to deal with that may interfere with hypertension self-care management. Social connectedness is a source of resilience for Black women to promote mental and physical health. Unfortunately, in the face of the Covid-19 pandemic, social distancing is a challenge further isolating Black women from their networks. How is social connectedness to manage stress and emotional well-being in a social-distancing society for Black women with hypertension? The research team proposed a synchronous web-based version of Enhanced Co-Created Health Education InterventioN (eCo-CHIN) that build the success and best practices derived from the original intervention. A Covid-19 session will be included as a way of helping Black women to maintain resilience and self-care during stressful times. The eCo-CHIN intervention is innovative and timely because the research team are using a synchronous platform preparing Black women on how to deal with Covid-19 while taking care of self. The primary investigator for this pilot study (Dr. Wright) is a Black Early Stage Investigator and former KL2 (career development) awardee. The interdisciplinary research team has the expertise and resources to deliver this Enhanced Co-CHIN intervention.

There is strong reason to believe that sleep promotion during adolescence could yield long-term health rewards; the investigators' data show that, when they get more sleep, Morning Larks have impressively reduced intake of overall calories and foods high in glycemic load that are linked to long-term health risk. Before that can be translated into major public health interventions, however, the field needs to understand why similar changes in sleep had no effect, or even an adverse effect, on adolescent Night Owls. This experimental study will clarify why there have been such discrepant effects across Morning Larks and Night Owls, with the goal of more broadly harnessing the promise of improved sleep in the prevention of obesity and long-term morbidity.

The present study is an open trial of ketogenic diets for adolescents and young adults (ages 12-21 yrs) in the depressive or mixed phases of bipolar disorder (BD). The investigators aim to determine whether combining standard of care pharmacological treatment for bipolar spectrum disorders with a 16-week ketogenic diet is well-tolerated and associated with improvements in depression, inflammatory and metabolic indicators, and executive functioning over the study period. The experimental treatment in this study is a 16-week full ketogenic diet. Four study sites (UCLA, U Cincinnati, U Colorado and U Pittsburgh) will recruit 80 total youth (20 each) from bipolar specialty clinics. All youth eligible for the ketogenic therapy will be provided with the ketogenic diet and standard of care pharmacological treatment. During the diet therapy youth will be seen by a study child/adolescent psychiatrist at least once a month (and more frequently when needed), with the psychiatrist recommending and providing side effects monitoring and pharmacotherapy as clinically indicated. The youth and caregivers will also meet with an expert dietitian who will coach all youth on maintaining the ketogenic diet (low carbs, high fats, medium protein) and making sure the child is tolerating the diet and getting enough liquid and nutrients, following the practice guidelines of the International Ketogenic Diet Study Group for treating youth. All youth and involved caregivers will also be provided will at least one motivational enhancement session to support them in goal setting and completion of the study elements. Throughout the study the investigators will assess metabolic (e.g., blood ketones, HOMA-IR) and inflammatory indicators (e.g., C-reactive protein), both for safety reasons and to assess correlates of symptomatic change. Independent evaluators will assess youth every month regarding their symptoms (depression, mania, anxiety, psychosis), psychosocial functioning, and quality of life. The investigators anticipate that the pilot will transpire over 24 months and be an important step toward establishing feasibility and acceptability of ketogenic therapy for this population, not only in terms of diet administration and compliance but also for obtaining symptomatic, metabolic and inflammatory measurements.

Participants with IBS are skin patch tested (no needles) to 80 different foods and food additives, compounded for patch testing, in search of food allergies. The testing requires 3 office visits within a 4 or 5 day period. The patches are taped to the back at Visit #. At Visit #2 48 hours later, the patches are removed from the skin and the outside border of each patch is marked with a felt tip marker. At Visit #3 (final visit) 1 or 2 days later, the patch test reading is performed by the doctor-investigator. An allergy is identified as a small red mark where the food was in contact with the skin for 48 hours. Those participants found to have food allergies are then placed on an avoidance diet (no calorie restriction) for 16 weeks where they either avoid eating the food(s) to which they are allergic (the \&#34;true\&#34; avoidance diet) or food(s) to which the testing did not show an allergy (this is called the \&#34;sham\&#34; avoidance diet). There is a 50/50 chance of going on either avoidance diet. The avoidance diet is assigned in such a way that neither the participant or the doctor-investigator knows which diet is being followed. After the 16 weeks, the participants answers a brief online questionnaire that asks about the IBS symptoms while following the avoidance diet. After the 16 week avoidance diet and final questionnaire are completed, those participants who were on the sham diet will be told of their true food allergies which they may try avoiding on their own.

The goal of this clinical trial is to see if timed fasting (periods of time that you don't eat) in participants who are receiving chemotherapy prior to surgery is achievable, safe and can improve quality of life, symptoms and outcomes (results) compared to participants who receive standard dietary recommendations in individuals being treated for epithelial ovarian cancer . The main questions it aims to answer are: * Is it feasible to use intermittent fasting during neoadjuvant chemotherapy? * Is it safe to use intermittent fasting during neoadjuvant chemotherapy? * Do participants find it acceptable to use intermittent fasting during neoadjuvant chemotherapy? Researchers will compare participants who receive standard dietary recommendations to see which method is more achievable, safe, and able to improve quality of life, symptoms and outcomes. Participants will: * Receive either the fasting intervention (schedule of times when you do not eat) or standard diet recommendations for 6-9 weeks prior to your surgery starting with the second cycle of chemotherapy. * All participants will be asked to complete chemotherapy and surgery, cancer imaging, baseline screening tests, nutritional assessments, food diaries, blood tests, and surveys about wellbeing. * Participants in the intervention group will be asked to follow a fasting schedule that consists of not eating for 16 hours a day followed by normal eating for the remaining 8 hours of the day for 5 days in a row followed by 2 days of regular eating each week.

Frequently Asked Questions

How much do Diet clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Diet clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Diet trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Diet is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Diet medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Diet clinical trials?

Most recently, we added TEAM-LEADS for Lupus and Dermatomyositis, Nutrition Program for Difficulty Walking and Plant-based Lifestyle Intervention for Diabetes to the Power online platform.
