U.S. children eat too little fruits and vegetables and whole grains, and too many energy dense foods, dietary behaviors associated with increased morbidity from cardiovascular diseases. Parents play a key role in shaping their child's diet and best practices suggest that parents should involve children in food preparation, offer, model and encourage a variety of healthy foods. In addition, while parents help to shape food preferences, not all children respond in the same way and certain appetitive traits, such as satiety responsiveness (sensitivity to internal satiety signals), food responsiveness (sensitivity to external food cues), and enjoyment of food may help explain some of these differences. Prior interventions among preschool aged children to improve their diet have not used a holistic approach that fully targets the home food environment, by focusing on food quality, food preparation, and positive feeding practices while acknowledging a child's appetitive traits. This proposal will build upon pre-pilot work to develop and pilot-test the feasibility, acceptability and preliminary efficacy of a novel home-based intervention. The proposed 6-month intervention, will include 3 monthly home visits by a community health worker (CHW) trained in motivational interviewing, that include in-home cooking demos. In between visits, parents will receive tailored text-messages 2x/wk. and monthly mailed tailored materials. During the last 3 months CHW phone calls will replace the home visits. The intervention will be tailored for individual families based on the child's appetitive traits. The proposed research will lay the groundwork for a larger trial to support, motivate, and empower low-income parents to prepare healthy meals and use healthy feeding practices, which will improve children's diets and ultimately their health.
Within many plants, such as seeds, nuts and cereals, there is a compound called phytic acid. Phytic acid has many beneficial properties, including producing molecules which slows down the damage that can be caused to other molecules within the body. Phytic acid has also been known to help in the treatment of cancer. Phytic acid binds iron very strongly. Iron is an extremely important nutrient not only for humans, but also for a lot of bacteria. In humans, iron is absorbed in the small intestine. Unfortunately, iron does not get absorbed very well and so a lot of it travels into the large intestine. The large intestine contains trillions of bacteria and a lot of these bacteria use iron as food. However, not all bacteria in the large intestine are 'good bacteria'. Some bacteria, such as Enterobacteria, can be harmful to people's health. For this reason, if iron is kept away from these 'bad bacteria' through the binding of phytic acid and iron, it could prove to be beneficial to human health. In general, the gut contains trillions of bacteria, many of which help to unlock extra nutrients from the food people eat. Some bacteria, such as Bifidobacteria, are often referred to as 'good bacteria' and are added to foods such as yoghurts. Many 'good bacteria' are able to survive without iron and this makes it even more important to make sure the 'bad bacteria' have limited access to iron. Otherwise, it is possible that the large intestine could populate more more harmful bacteria than beneficial bacteria. In this study, investigators will ask participants to consume either the test capsule, which contains phytin (a salt form of phytic acid), or a control capsule, which contains a powder resembling phytin but is actually an inactive substance. The investigators are interested in whether consuming these capsules will decrease Enterobacteria (one of the 'bad bacteria' in the large intestine).
Compare weight loss and metabolic parameters in patients using a low starch dietary education program vs. traditional treatment (i.e., prescribing metformin, low calorie diet and exercise) for health improvement in women with PCOS.
The Supermarket and Web-based Intervention targeting Nutrition (SuperWIN) for cardiovascular risk reduction is a novel, randomized controlled trial aimed at increasing diet quality and decreasing cardiovascular risk. SuperWIN will deliver individualized, nutrition education at the point-of-purchase (POP), either in the aisles of the physical store or via online shopping platforms coupled with other modern software tools.
The purpose of this study is to assess the impact of consuming unprocessed and processed red meat on gut microbiota in young healthy adults in a cross-over, randomized controlled feeding trial.
The purpose of this study is to examine the effects of dietary calcium supplementation on weight loss, bone density, and markers of health and fitness in women participating in the Curves exercise and diet program.
The project examines over several days how the distribution pattern of dietary protein stimulate and affect the protein turnover of important proteins in the aging perspective, such as skeletal muscle proteins.
The purpose of the study is to evaluate the safety of short-term (6 month) low or very-low carbohydrate diets in prepubertal children 2 to <12 years old with type 1 diabetes. Participants will be randomized to either low carbohydrate diet (carbohydrate makes up 30-39% of total daily calories) or very-low carbohydrate diet (carbohydrates are 20-29% of total daily calories). The investigators will evaluate metabolic effects of these diets by measuring the counter-regulatory hormone response to hypoglycemia at baseline and again at 3 months. Other outcomes include diabetes control as measured by HbA1c, growth and weight gain, lipid profiles, and body composition.
50 vegans and 50 omnivores will be recruited at the Erasme Hospital, Brussels. Hypothesis - Relative induced-hyperuricemia by the vegan diet is not associated with impaired endothelial function if vitamin B12 and folic acid levels are normal. - Quantification of xanthine oxidoreductase (XOR) isoforms varies according to the diet. Omnivores present more xanthine oxidase (XO) than vegans in which the xanthine dehydrogenase (XD) isoform is more prevalent. - The vegan group has more favorable oxidant, metabolic and inflammatory profiles than the omnivore group.
