TESTE DEIN WISSEN

List the essential components of the diet.

Lösung anzeigen
TESTE DEIN WISSEN
  • Carbohydrates - mainly supplies energy
  • Fats - supplies energy and essential fatty acids
  • Proteins - supplies energy and amino acids
  • Vitamins
  • Fibre - for normal GI function
  • Water - maintains hydration
  • Minerals

TESTE DEIN WISSEN

Define the components of daily energy expenditure.

Lösung anzeigen
TESTE DEIN WISSEN

Daily energy expenditure is the sum of:

  • Basal metabolic rate (BMR) - e.g. maintainenance of cells/temperature/organ function
  • Diet-Induced Thermogenesis (DIT)- energy required to process food)
  • Physical activity level (PAL) - intensity and duration of activity

Why are minerals important for diet?

Lösung anzeigen
TESTE DEIN WISSEN
  • Electrolytes maintain ionic gradients
  • Ca and P essential for structure (bones and teeth)
  • Ca signalling molecule e.g. muscle contraction
  • Fe important for Hb

What are the different dietary reference values?

Lösung anzeigen
TESTE DEIN WISSEN

RNI - Reference Nutrient Intake

  • Used for protein, vitamins and minerals

EAR - Estimated average requirement

LRNI - Lower Reference Nutrient Intake

  • Intakes below LRNI are insufficient for most people

TESTE DEIN WISSEN

How is kwashiorkor developed?

Lösung anzeigen
TESTE DEIN WISSEN
  • Calorie intake normal but protein deficiencies
  • Essential amino acids are not supplied
  • Liver is unable to synthesise lipoproteins (lipoproteins formed to allow transport of lipids around the body)
  • This causes accumulation of fat in liver - fatty liver
  • This causes hepatic dysfunction
  • Liver also unable to synthesise certain amino acids e.g. albumin
  • Less aa in plasma - reduces osmotic pressure causing fluid shift which develops into oedema

What is thought to cause re-feeding syndrome?

Lösung anzeigen
TESTE DEIN WISSEN
  • Downregulation of enzymes in urea cycle causing ammonia toxicity
  • Rapid increase in metabolism will utilise more P, Mg, K - body stores already low so can cause hypophosphatemia
  • Occurs in anorexic, cancer and post surgery patients
  • Can lead to confusion, coma. convulsion, death

Which proteins are conditionally essential?

Lösung anzeigen
TESTE DEIN WISSEN

In children and pregnant women there is a lot of rapid growth occurring which means high rate of protein synthesis.

May require extra cysteine, arginine and tyrosine (CAT).

Why are fats important in the diet?

Lösung anzeigen
TESTE DEIN WISSEN
  • Lipids in triacylglycerol form release much more energy when oxidised compared to proteins and carbohydrates
  • Required for absorption of fat soluble vitamins (K,A,D,E)
  • Provide essential fatty acids e.g. linoleic and linolenic acids which cannot be synthesised by body
