8 Clinical Trials for Various Conditions
Due to the lack of direct evidence of optimal iodine intake of Chinese children, pregnant and lactating women and infants were found during the recent revision of Chinese dietary reference intakes (DRIs) of iodine in 2013 by the applicant Pro. Zhang, and no systematical research about compensatory mechanism of iodine nutrition in lactating women was found yet. Previous study funded by United Nations International Children's Emergency Fund (UNICEF) cooperated with the international experts on iodine and key project of national natural science foundation of China under the guidance of Pro. Zhang, had obtained the safe intake range of iodine from children and pregnant women, more than 10 joint papers were published, which laid the foundation of population study and international cooperation.
Malnutrition of the fat-soluble nutrient vitamin E (α-tocopherol; αT) is problematic. Since αT is rich in plant foods (e.g. spinach) that are mostly absent of accessible lipid, dietary patterns that can potentiate αT bioavailability by pairing vegetables with lipid-rich foods have been emphasized. The purpose of this study is to use deuterium-labeled spinach (containing stable isotopes of αT) to validate eggs as a dietary tool to improve αT bioavailability directly from a model plant food, and hence achieve nutrient adequacy. It is expected that compared with deuterium-labeled spinach alone, co-ingestion of eggs will dose- and time-dependently increase plasma bioavailability of spinach-derived deuterium-labeled αT without affecting time to maximal concentrations or half-lives. Further, phospholipid-rich egg yolk lipid will enhance nutrient bioavailability compared with vegetable oil. The outcome will therefore support an egg-based food pairing that can enhance the health benefits of plant-centric dietary patterns.
Malnutrition of the fat-soluble nutrient vitamin K (phylloquinone; PQ) is problematic. Since PQ is rich in plant foods (e.g. spinach) that are mostly absent of accessible lipid, dietary patterns that can potentiate PQ bioavailability by pairing vegetables with lipid-rich foods have been emphasized. The purpose of this study is to use deuterium-labeled spinach (containing stable isotopes of PQ) to validate eggs as a dietary tool to improve PQ bioavailability directly from a model plant food, and hence achieve nutrient adequacy. It is expected that compared with deuterium-labeled spinach alone, co-ingestion of eggs will increase plasma bioavailability of spinach-derived deuterium-labeled PQ without affecting time to maximal concentrations or half-lives. Further, phospholipid-rich egg yolk lipid will enhance nutrient bioavailability compared with vegetable oil. The outcomes will serve as the foundation for easy-to-implement message of public health importance in support of whole eggs and egg whites as part of a plant-based dietary pattern.
In this study, we will evaluate the effectiveness of several doses of oral selenomethionine in raising biomarkers of selenium status including plasma selenium concentrations.
Early nutrition critically influences growth, neurodevelopment and morbidity among infants born of very low birth weight (VLBW), but current one-size-fits-all feeding regimes do not optimally support these vulnerable infants. There is increasing interest in "precision nutrition" approaches, but it is unclear which Human Milk (HM) components require personalized adjustment of doses. Previous efforts have focused on macronutrients, but HM also contains essential micronutrients as well as non-nutrient bioactive components that shape the gut microbiome. Further, it is unclear if or how parental factors (e.g. body mass index, diet) and infant factors (e.g. genetics, gut microbiota, sex, acuity) influence relationships between early nutrition and growth, neurodevelopment and morbidity. Understanding these complex relationships is paramount to developing effective personalized HM feeding strategies for VLBW infants. This is the overarching goal of the proposed Optimizing Nutrition and Milk (Opti-NuM) Project. The Opti-NuM Project brings together two established research platforms with complementary expertise and resources: 1) the MaxiMoM Program\* with its clinically embedded translational neonatal feeding trial network in Toronto (Dr. Deborah O'Connor, Dr. Sharon Unger) and 2) the International Milk Composition (IMiC) Consortium, a world-renowned multidisciplinary network of HM researchers and data scientists collaborating to understand how the myriad of HM components contribute "as a whole" to infant growth and development, using systems biology and machine learning approaches. Members of the IMiC Corsortium that will work with on this study are located at the University of Manitoba (Dr. Meghan Azad), University of California (Dr. Lars Bode) and Stanford (Dr. Nima Aghaeepour).
Insomnia is not a natural part of aging but is higher in older adults because of a variety of factors common in later life. One of these factors may be a deficient magnesium status. This study will look at whether or not magnesium supplementation will improve sleep.
The purpose of this study is to investigate the energy needs and nutritional status of adolescent girls in Abia State, Nigeria
This is a crossover study utilizing a Dietary Approaches to Stop Hypertension (DASH) diet and a whole-food, plant-based diet among subjects with type 2 diabetes who require insulin. Outcomes are short-term changes in insulin requirements and changes in various biomarkers.
