  1. 1. Dietary Patterns : Identification and Health Implications in the Swedish Population

    Författare :Erika Ax; Per Sjögren; Agneta Andersson; Wulf Becker; Berit Lilienthal Heitmann; Uppsala universitet; []
    Nyckelord :Dietary Pattern; Dietary Recommendations; Dietary Survey; Environmental Contaminants; Healthy Diet Indicator; Heatlhy dietary pattern; Low-Carbohydrate; Mediterranean diet; Nutritional Biomarkers; Obesity; Overweight; Principal Component Analysis; Prostate Cancer; Sweden; Traditional dietary pattern; Medicinsk vetenskap; Medical Science; Nutrition; Nutrition;

    Sammanfattning : We eat foods not nutrients. What is more, we eat them in combinations. Consequently, capturing our complex food habits is likely an advantage in nutrition research. The overall aim of this doctoral thesis was therefore to investigate dietary patterns in the Swedish population –nutrient intakes, nutritional biomarkers and health aspects. LÄS MER

  3. 2. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    Författare :Shahid Ullah; Urs Berger; Tomas Alsberg; Michael McLachlan; Jonathan W. Martin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Science; PFASs; PFAAs; PFOA; PFOS; Precursor; FOSA; PAPs; Method development; LC-MS; SPE; Dietary sample; Drinking water; Human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. LÄS MER

  4. 3. Nutritional metabolomics: The search for dietary exposure variables

    Författare :Millie Rådjursöga; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolomics; nutrition; NMR; serum; urine; postprandial; dietary intake;

    Sammanfattning : To establish associations and causation between diet and health, objective and reliable methods are needed to measure dietary exposure. Metabolomics provide an unbiased tool for exploring the modulation of the human metabolome in response to food intake. LÄS MER

  5. 4. On the regulation of immune responses to dietary and self antigens

    Författare :Susanne Lindgren; Göteborgs universitet; []
    Nyckelord :Tolerance; regulatory T cells; self antigens; oral tolerance; dietary antigens; intestinal epithelial cells; exosomes; Staphylococcus aureus enterotoxin A;

    Sammanfattning : Regulatory mechanisms are necessary to avoid the misdirected aggressive immune responses responsible for the pathology seen in autoimmunity and allergy. Thymic-derived CD4+CD25+ regulatory T cells are indispensible for this regulation. We investigated if CD4+CD25+ Treg prevents auto-reactive responses in adult peripheral blood and cord blood.

  7. 5. Limited dietary diversity and consumption of ultra-processed and deep-fried foods among adolescents in rural Bangladesh : uncovering the two faces of suboptimal diet

    Författare :Mohammad Redwanul Islam; Eva-Charlotte Ekström; Syed Moshfiqur Rahman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rural adolescents; Dietary diversity; Ultra-processed food; Deep-fried food; Bangladesh; Matlab; Nutrition;

    Sammanfattning : Background: With an estimated number of 1.2 billion in the world, adolescents represent a major transformative force in global health. Optimum adolescent nutrition is increasingly important for scaling up population health gains in low- and middle-income countries (LMICs) of South Asia. LÄS MER
