NTS 135 Lecture Notes - Selenium Deficiency, Vitamin A Deficiency, Probiotic
Document Summary
Describe two ways the gi tract assists the immune system. What dietary patterns lead to chronic, low levels of inflammation: the immune system. Collection of diverse tissues: skin intestinal cells lymphoid tissue. Work together to: prevent infection, break down aged, dying cells remove abnormal cells, skin. Essential fatty acids, vitamin a, niacin, and zinc help maintain skin health. Skin lesions provide opening for bacteria to penetrate. Nutrient deficiencies weaken integrity of skin: vitamin a deficiency lowers enzyme lysozyme, needed to kill bacteria. Cells of small and large intestines: packed close together form barrier to microorganisms. Gut-associated lymphoid tissues (galt): assists cells of gi tract in keeping pathogens from entering bloodstream. Nutrients: adequate protein, vitamin a, vitamin b-6, vitamin b-12, vitamin c, folate, and zinc. Nutrient deficiencies: cause intestinal cells to break down leads to diarrhea and bacteria in bloodstream, white blood cells.
