Diet, Food, and Nutrition

The goal of this dietary intervention study in generally healthy adults is to develop new ways to use blood samples to measure the common types of highly processed foods and beverages that people eat on a regular basis. The main aims to answer are: What small molecules are elevated in blood after eating different types of highly processed foods and beverages consistently for 1 week? Researchers will compare 3 different test diets with 1 control diet that does not have any highly processed foods in the same individuals to see which circulating blood markers change. Participants will: * Complete 3 diet phases, each 2 weeks long * Receive a meal plan and study foods and beverages to follow for each 2-week phase * Come to the clinic every week for blood draws, urine samples, and stool collection kits

The purpose of this study is to determine which of the following four service models is most effective for reducing fall risk among home-delivered meal clients: (1) meals alone, (2) meals + registered dietitian services, (3) meals + occupational therapy services, (4) meals + registered dietitian + occupational therapy services.

The goal of this observational study is to examine the relationship between metabolic syndrome (MetS) and periodontitis, and to evaluate the role of the Dietary Inflammatory Index (DII) in this association. The main question it aims to answer is: Does a pro-inflammatory diet, as measured by the DII, increase the risk or severity of periodontitis in individuals with metabolic syndrome? Participants will include adults who meet the diagnostic criteria for metabolic syndrome. Their periodontal health will be assessed through standard clinical parameters, and dietary data will be collected using a validated food frequency questionnaire to calculate individual DII scores. The study will observe and analyze these factors to explore potential links between diet-induced inflammation, systemic metabolic health, and periodontal outcomes.

The goal of this observational study is to investigate the relationship between chronic kidney disease (CKD) and periodontitis, and to evaluate the potential mediating role of dietary inflammatory potential, measured by the Dietary Inflammatory Index (DII), in this association. The main question it aims to answer is: Does a pro-inflammatory diet, as reflected by a higher DII score, exacerbate periodontal inflammation in individuals with chronic kidney disease? Participants will include adults diagnosed with CKD at various stages. Periodontal status will be assessed through clinical parameters such as probing depth, clinical attachment loss, and bleeding on probing. Dietary intake will be evaluated using a validated food frequency questionnaire, and DII scores will be calculated accordingly. The study will aim to observe and analyze whether dietary inflammation contributes to increased periodontal disease severity in CKD patients, potentially offering insight into modifiable risk factors relevant to both systemic and oral health.

This research aims to study the dual effectiveness of incorporating soluble fibre and osmotic carbohydrates (SOLOS), with or without restricting fructans and GOS, and present novel findings in managing GI symptoms in patients with functional bowel disorders with constipation. These findings may also support researchers and clinicians in shaping new dietary approaches in the management of general constipation symptoms.

The objective of the research project is to establish an evidence-based sustainable nutrition service delivery platform for optimizing pregnancy weight gain, increasing dietary diversity of adolescent girls, and ensuring proper physical growth of under 2 children. Hypothesis 1. Pregnant Women: Intensive nutrition and WASH counseling, iron-folate, calcium supplementation during pregnancy, can improve gestational weight gain and improve hemoglobin status in pregnant women in a slum of Dhaka city 2. Adolescent girl: Iron and zinc supplementation and nutrition counseling on dietary diversity could improve nutritional status and dietary diversity score in adolescent girls of slums in Dhaka 3. Children \<2 years: Counselling on IYCF, growth monitoring, and promotion, ensuring six-monthly vitamin A supplementation, counseling on WASH, treatment of acute malnutrition, and daily 1 egg supplementation for 3 months for severely stunted children can improve the nutritional status of children 4. Counselling to improve Water, Sanitation and Hygiene (WASH) practice: WASH intervention can improve EED biomarkers

The NutriNet-Santé study was set up to investigate nutrition and health relationships. Specifically, it was the first web-based cohort worldwide on such a large scale (n=171 000 as of 2021) focused on the complex link between nutrition and health status. It is characterized by a very detailed assessment of nutritional exposure and dietary behavior. https://etude-nutrinet-sante.fr/ https://info.etude-nutrinet-sante.fr/en
