ChildRAUM – Children’s nutrient requirements, absorption, utilization & metabolic rates with emphasis on dairy protein

Nutrients and not the least protein is important for a child’s health and growth, and protein requirements change during different growth periods and with illness. However, little is known about the exact protein requirements during growth in healthy children.
The ChildRAUM project will determine in detail and in the broadest sense post-absorptive metabolism, post-prandial metabolism and nutrient requirements as well as endocrine responses in children in 3 age categories. For this, protein, amino acids, fat and glucose metabolism will be investigated before and after ingestion of a liquid meal containing a mixture of protein (casein isolate), fat and glucose to establish protein absorption, systemic protein turnover, and amino acids metabolism (including liver function) and endocrine responses next to glucose and oral Chylomicron and liver fat handling (VLDL-TAG) and endogenous lipolysis.
Children in different ages will be included, this will provide knowledge of protein and general nutrient requirements during growth in healthy children, as well as biomarkers for energy requirements to be used at children hospitals.

GutBioMod – Extracellular Vesicles in milk as Biological Modulators of Gut development and function during early life

Milk carry two kinds of bioactive phospholipid particles, milk fat globules and extracellular vesicles (EVs). EVs from milk display a distinct molecular composition of lipids, proteins, and an aqueous core with nucleic acids, especially microRNA (miRNA). EVs are thought to deliver not yet fully understood messages to the cells in gastrointestinal tract in the infant, by its content of nucleic acids, which appears to be important for the gut- and immune system development, also later in life. However, EVs are only limitedly present in current infant formulas on the market today. In GutBioMod we want to study how raw milk and dairy derived EVs are influencing the intestinal cells upon uptake and which processes in the gastrointestinal tract that are influenced. By providing a deeper understanding of this milk-born mother-to-child signalling axis during early life, the project will increase our knowledge of the regulatory effects of nutrition and may help to improve the quality of infant formula.

DACAPRO – Dairy calcium to promote prebiotic effects in the gut

Calcium is a characteristic constituent of milk and dairy products, which are recognized as a key calcium sources providing support for bone health. In addition, calcium may also exert important effects that promote gut health, via its ability to influence gut microbiota (GM) composition and functionality. Through controlled in vitro fermentation studies where different calcium sources and prebiotics are combined as substrates, the DACAPRO project aims to generate fundamental evidence on the potential of dairy calcium to promote the effects of prebiotics and thereby improve gut health. This will be achieved through integrated metabolomics, metagenomics and gene expression analyses to identify the detailed effects of calcium and prebiotic combinations on in vitro simulated GM composition and its metabolic capacity and activity. This knowledge will be a cornerstone to understand the role of dairy as a unique biofunctional food segment targeted at gut health promotion.

YourGutBrain – Yoghurt to alter gut movements and brain function

Increasing evidence suggest that bowel habits are linked to mental health. Consumption of fermented dairy has been reported to accelerate intestinal transit time and to affect cognitive performance, respectively. The YourGutBrain project will investigate whether intake of fermented dairy in comparison with non-fermented dairy increases weekly bowel movements and concordantly improves cognitive performance. This will be investigated through a dietary intervention study including healthy women with few bowel movements per week. A wide range of measures related to the gut and the brain will be assessed upon consumption of fermented dairy and non-fermented dairy, respectively. Together, this will provide insights into whether fermented dairy can affect bowel habits and cognition, as well as potential underlying mechanisms linking the gut and the brain.

LAMETA – Lactate – the link between fermented dairy products and metabolic health?

Intake of fermented dairy products is associated with a decreased risk of type 2 diabetes and cardiovascular disease. Since fermentation increases the content of lactate, lactate may be the previously unknown link between fermented dairy intake and metabolic health. In a recent study, we have found that oral intake of lactate slows gastric emptying, inhibits appetite, and also inhibits the appetite hormone ghrelin and stimulates the secretion of the incretin hormone GLP-1 and insulin. Therefore, the aim of the LAMETA project is to investigate how the addition of lactate to meals affects hormone secretion, nutrient absorption, and substrate utilization in individuals with obesity and insulin resistance. This will be done through both animal and human studies and with a new PET scan method to measure organ-specific meal fat uptake. The results of the LAMETA project will elucidate whether lactate and lactate‐containing dairy products could prevent and treat metabolic diseases such as diabetes type 2, obesity and insulin resistance.

CASGUT: Caseins for gut comfort in infants

Most infant formulas (IF) are based on processed milk proteins, consisting of bovine whey proteins added to skimmed milk powder to obtain whey/casein (CN) ratio of 60/40 to approach the ratio in human milk (HM). The project aims to clarify the potential benefits of gently-processed intact or hydrolyzed micellar casein isolate (MCI) in IFs and how they compare to HM in terms of mild gastric clotting for improved gut comfort and motility and the release of bioactive peptides for improved gut health. It is currently unknown how the widely studied rennet-induced coagulation of bovine milk in relation to cheese-making properties translates into clotting properties in the infant stomach. This is studied in the CASGUT project; by combinations of piglet studies and lab based pilot experiments in the context of the established CASGUT AU/UCPH project consortium.

SMiL – Special Milk Lipids for Improving Metabolic Health

Medium-chain saturated fatty acids (MCSFAs) comprise about 10% of the fat found in cow milk. MCSFAs have been shown to increase satiety and improve metabolic syndrome. We have two aims. One, by using different transgenic mouse models and by conducting mechanistic human experiments, we want to identify the mode-of-action underpinning the health benefits of MCSFAs. Two, we will create a novel dairy product that is highly enriched in MCSFAs and assess its potential health benefits in humans.

DAIRYMAT

A food item is more than the content of its single nutrients. The structure of the food at all levels affects the digestion and uptake of the nutrients in the human gut. In this project, we study how the dairy matrix influences nutrient uptake with specific focus on post-prandial lipaemia. The perspective is to be able to design better foods with a more targeted structure for nutrient availability by understanding of the effects of this relationship in dairy foods.

OmniSaM: The Omnibus Satiety Metric

A multimodal metric for predicting the satiating effects of real foods and drinks

Satiation depends on many human factors related to e.g. physiology, perception and psychology and as such has proven very difficult to measure and predict accurately. Healthy foods that fill faster and for longer are desirable for public health, but current methods for measuring the satiating capacity of foods have very weak predictive val-ues. This ambitious project proposes to combine the primary processes underlying the satiety cascade, including brain, blood and behavior measurements to develop a meth-od which can accurately predict future caloric intake. The Omnibus Satiety Metric will enable the development of superior satiety optimized foods in the context of weight and lifestyle management for the consumer, as well as enabling the future development of a rapid measurement for satiation with wider applicability in the nutrition and medical sectors.

This project investigates the optimal combination of milk proteins and ketone bodies to counteract post-inflammatory protein and muscle waste in a new clinical human model combining inflammation(LPS), bed rest and fasting. The goal is to be able to support healing and recovery with targeted nutrition, which would improve quality of life for patients and reduce health care costs.
