  1. anabolism
    formation of larger molecules from smaller ones-> requires energy
  2. catabolism
    breakdown of molecules 9releases energy)
  3. albumin
    • constitutes 60% of total body protein
    • Low level-> malnutrition, disease
    • Half life 18-21 days-> lag in detecting nutritional problems
    • Not accurate for measurement if fluid imbalance
  4. prealbumin
    Fluctuates daily-> better marker to indicate acute change of albumin
  5. creatinine
    End product of skeletal muscle metabolism

    Excellent indicator of renal function-> increased level -> impaired kidneys/ loss of muscle mass?
  6. hemoglobin
    • Composed of heme (iron rich compound)
    • And globulin (serum protein)

    Low hemoglobin-> low iron or blood loss?

    Decreased globulin-> for antibodies, glycoprotein, lipoproteins, clotting factors, key enzymes-> insufficient intake or blood loss?
  7. Overweight/pre obese
    BMI 25-30
  8. obesity
    BMI >30
  9. enteral nutrition
    tube feeding through intestinal tract
  10. Parenteral nutrition
    Intra venously
  11. Clear liquids
    • Provides fluids
    • Some simple carbohydrates
    • Water, tea, coffee, broth, clear juice, popsicle, carbonated beverages, gelatin
  12. Full liquids
    • Clear liquids
    • Food items liquid at room temperature e.g. soups, milk, shakes, puddings, custards, juices, hot cereal, yoghurt
    • Short term
    • Often high calorie/protein supplements added
  13. Mechanical soft diet
    • Full liquid diet
    • Soft vegetables/ fruit, shredded meat/ bread/ pastries/ egg/cheese
    • Full range but low in fiber
    • -> risk of constipation
  14. Puréed diet
    • Blended diet
    • Often liquids are added
  15. Diets modified for disease
    Sodium-restr.: blood pressure/ fluid imbalance

    Fat restr.: cholesterol, trigyceride, weightloss

    Protein controlled: kidney/ liver desease

    Calorie protein push: wound healing, burns,
  16. calcium
    Bone, teeth, blood clotting, nerves, cellular metabolism, heart action

    Deficiency: bone loss, tetany, rickets, osteoperosis

    Dairy, green leafy vegetables, whole grains, nuts, legumes,
  17. Magnesium Mg
    • Thyroid hormone secretion
    • Enzymes, metabolic rate,
    • carbohydr/ protein metabolism
    • Nerve and muscle function (also cardiac)

    Deficiency: tremor, spasm, weakness, muscle pain, poor cardiac function

    Whole grains, legumes, broccoli, potatoes, green leafy veggies
  18. Phosphorus P
    Bone tooth strength, metabolism, enzymes, acid-base balance

    Deficiency: bone loss, poor growth

    Dairy, pork, beans, eggs chicken, chocolate
  19. Potassium K
    BP regulation, fluid balance intracellular, muscle contraction, protein synthesis

    Deficiency: muscle weakness, weak pulse, fatigue,

    Fruits, vegetables, legumes, milk,...
  20. vitamin A
