Sugar-sweetened beverages (SSBs) are one of the few dietary items causally linked to the development of obesity and chronic disease. SSB consumption among young adults are particularly concerning, because of the high levels of consumption and the influence of disease risk in later life. College students, particularly freshmen, are a captive audience when it comes to dietary consumption because many of them consume their meals in residential dining halls. We are currently working with Michigan Dining to implement warning labels on SSB fountain dispensers to examine whether carefully tailored signage could alter beverage choices of college students. The current study aims to assess changes in dietary intake before and after the labels are posted, in a representative sample of University of Michigan students who eat at residential dining halls.

Aim: To evaluate the effect of nutrition education intervention (NEI) on glycemic control and other diabetes-related outcomes of patients with type 2 diabetes mellitus (T2DM), at a tertiary health Center, in Basrah, Iraq. Participants and setting: The study was involved 208 participants (20-64 years) diagnosed with T2DM at least 6 months before the study and had poorly controlled diabetes (HbA1c ≥ 7%). The study setting is the outpatient clinics at a tertiary health Center in Basrah, Iraq. Intervention: This randomized controlled trial design. The participants were allocated to either intervention group (IG), or control group (CG). A total sample size was 208 participants with T2DM (104 per group) to detect a 5% reduction in glycemic control (HbA1c), at visit time 1 (3 months after intervention) and visit time 2 (3 months after following up) and allowing 30% drop out rate. The intervention period is 22 weeks long with the following mechanisms: the curriculum (twelve weekly classes, 1 to 1.5 hrs. each); follow-up classes (one monthly each lasting 1 to 1.5 hrs.); nutrition education materials (pamphlets) and reminder calling before each session for IG. The participants in the CG received classes about diabetes and its complications with some advice related to physical activity on different days on IG. Besides, they received the same pamphlets at the end of the study. Both groups continued with the usual medical care at respective Center. The participants in the IG group received nutrition education classes. The classes are offered in the meeting hall in the center by face- to- face using the simple Arabic language, which utilized lecture method using PowerPoint presentations and whiteboard, lecture-discussion groups, and related videos. The nutrition education classes were administered by a nutritionist and a team of endocrinologists, and diabetes experts. The content and strategies utilized in the classes were based on Health Belief Model theory (HBM). Outcomes: the outcomes were evaluated at visit time 1 (at 12 weeks of intervention) and at visit time 2 (at 22 weeks of the follow-up period) for both groups. The outcomes were included HbA1c, metabolic parameters, nutritional status, HBM constructs, diabetes knowledge (DK), and health literacy (HL). It is assumed that the NEI will reduce the HbA1c levels by at least 0.5% at three months and the levels will be lower in IG compared with CG, and the lower levels will be continued at 22 weeks in IG.
The purpose of this study is to determine whether a 30 day beef intervention can improve peak cognitive performance in young, normally menstruating adult women. The control group will consume a daily portion of macronutrient equivalent vegetable source of protein.
The purpose of this pilot study is to determine the preliminary efficacy, safety, and acceptability of time restricted feeding (TRF) among a sample of 12 adults with Relapsing-Remitting Multiple Sclerosis (RRMS). The specific aims of this study are: 1: To determine preliminary efficacy of TRF for reducing symptom burden, improving inflammatory markers, and reducing cardiometabolic risk among adults with RRMS. 2: To determine the safety and participant acceptability of TRF. Participants will be asked to consume all food during an 8-hour window each day and not eat for the remaining 16 hours. All participants will follow this eating pattern for 8 weeks.
There is objective need to evaluate the differences in dietary intake (DI), body composition (BC), lifestyle (LS) and cardiovascular diseases (CVD) risk factors between healthy and active vegetarinas (VEG) and non vegetarians (non VEG) and references (according to gender). The aim of this cross-sectional study for investigators is to document the potential differences in DI (non adjusted and adjusted), BC, LS and CVD risk factors between healthy and active VEG and non VEG, aged from 18 to 80 years, and to evaluated correlation between DI variables and CVD risk factors. The study during the COVID-19 pandemic period will be self-reported. As variables the investigators will include the dietary intake, BC (body height, body weight, body mass index (BMI), body fat percentage (BF %)), lifestyle status (physical activity, daily seating, hygiene of sleep, socio-economic status, and motive for practicing chosen diet). The investigators will also record their maximum (lifetime) body weight, lipids (total-cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides) and blood pressure (BP) status. The investigators hypothesis are: (H1): There are differences in DI and quality of the diet (compared with references). (H2): There are differences in BC between the VEG in non VEG (according to gender). (H3): The are no differences between in CVD risk factors between the VEG and non VEG (according to gender). (H4): The are no differences in the effect of two intervals of time restricted feeding (i.e., 8-12 hours vs. 12-16 hours) within dietary pattern (according to gender).
Mechanistic data show that compounds in fruits and vegetables have anti-inflammatory and anti-carcinogenic properties that can reduce breast cancer risk. However, observational and interventional studies have provided mixed results, and a recent report by the American Institute for Cancer Research (AICR) concludes that the data are insufficient but suggestive that non-starchy vegetables and foods containing carotenoids reduce risk. Measurement error, relatively low levels of carotenoid-rich fruit and vegetable intake in the study populations, emphasis on diet in later adulthood, and confounding factors likely contribute to the weak associations. Therefore, the investigators will conduct a randomized diet intervention trial in young women to assess the extent to which at least 8 to 10 daily servings of deeply pigmented and nutrient dense fruits and vegetables reduces biomarkers of breast cancer risk. The intervention is focused on breastfeeding women because: 1) pregnancy and lactation are normal early life course events; 2) the risk of pregnancy-associated breast cancer (PABC) is increased for up to 10 years postpartum; 3) a dietary intervention to reverse the detrimental molecular changes associated with puberty and pregnancy is more likely to be successful in younger than in older women;4) a diet rich in fruits and vegetables is hypothesized to reduce the inflammation during lactation/weaning and lower PABC risk; 5) postpartum lactating women may be a highly motivated population; and 6) breastmilk provides access to the breast microenvironment and breast epithelial cells to non-invasively assess the diet intervention directly in the breast. Four hundred nursing mothers will be randomly assigned to either the intervention arm, in which they are asked to increase fruit and vegetable intake to at least 8 to 10 daily servings for one year, or to a control condition in which participants receive a dietary guideline for breastfeeding mothers. Women in the intervention arm will receive counseling and boxes of fruits and vegetables for the first 20 weeks, after which they will continue to receive counseling. Changes in DNA methylation and cytokine profiles in breastmilk will be evaluated. Maternal weight and body fat distribution, and infant growth will be monitored. These results will greatly expand our knowledge of how diet alters molecular pathways in a specific organ, ultimately contributing to both breast cancer etiology and prevention.
The CHEER study takes advantage of a natural experiment happening in South Carolina (SC). The South Carolina Department of Social Services implemented new healthy eating and physical activity standards through a state-wide policy for family child care homes that participate in the ABC Grow Healthy program. Thus, CHEER is a quasi-experimental, two-group, pre-test/post-test design study.
As a result of unhealthful lifestyle practices including nighttime ingestion and excess energy-dense food and beverage intake, college students are presenting with metabolic abnormalities and excess weight gain that increases their risk for chronic health conditions including cardiovascular diseases and type 2 diabetes. Research has shown that prolonging nightly fasting intervals can result in health improvements in both animal models and human subjects. Time-restricted feeding (TRF), a form of intermittent fasting may offer an exciting, non-pharmacologic approach to improve cardiometabolic health in this population by restricting food intake to feeding windows that align with circadian biology.
