  1. 1. Fermentation of quinoa, canihua and amaranth to degrade phytate and improve mineral bioavailability

    Författare :Vanesa Castro-Alba; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quinoa; Canihua; Amaranth; Iron; Zinc; Calcium; Phytate; Fermentation; Accessibility; Bioavailability;

    Sammanfattning : Plant-based diets are the main source of nutrients for vegetarians worldwide and for low-income inhabitants of developing countries, such as in rural areas of Bolivia. These diets may contain high levels of mineral inhibitors such as phytate that impairs mineral absorption in the human gut. LÄS MER

  3. 2. Food habits in Swedish adolescents. Meal pattern, food choice and bioavailability of iron 1994 and 2000

    Författare :Agneta Sjöberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescent nutrition; food habits; interview; meals; dietary iron; iron fortification; bioavailability; energy intake; energy expenditure; doubly labelled water;

    Sammanfattning : The general iron fortification of white wheat flour was removed after 50 years of iron fortification. It was considered important to evaluate the effects of withdrawal of iron fortification among vulnerable groups in the population. Adolescents have high iron requirements for growth and the girls for menstrual losses. LÄS MER

  4. 3. Nutrient and Organic Matter Dynamics in Beech Forest Floors, in Relation to the Presence of Ground Flora

    Författare :Frida Andréasson; Biologiska institutionen; []

    Sammanfattning : The objective of this thesis was to quantify differences between adjacent patches with and without ground flora of Deschampsia flexuosa L. Trin or Anemone nemorosa L. in two acid European beech (Fagus sylvatica L.) forest floors in south-west of Sweden. LÄS MER

  5. 4. Nutritional Assessment in a Rural Area of Bolivia. A Study of Zinc and Iron Deficiencies and Bioavailability

    Författare :Claudia Lazarte; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zinc; iron; deficiencies; bioavailability; fermentation; developing countries; plant-based diets;

    Sammanfattning : While originally, protein-energy deficiency was considered the main factor of malnutrition, it is now understood that micronutrient deficiencies play a fundamental role in a variety of health and disease outcomes. Zinc and iron deficiencies are still highly prevalent in low-income countries, whereas insufficient intakes and diets with low mineral absorption are the major causes. LÄS MER

  7. 5. Iron absorption in man - diet modification and fortification

    Författare :Michael Hoppe; Göteborgs universitet; []
    Nyckelord :Iron absorption; Serum iron; Relative bioavailability; Elemental iron; Iron bioavailability; Iron fortification; Dietary modification; Developing countries;

    Sammanfattning : Background: Iron (Fe) deficiency is globally the most common form of nutrient deficiency. The approach to combat this problem can be divided into two major strategies a): increasing the dietary Fe bioavailability by diet modification, or b): increasing the Fe intake through fortification.
