Study Notes

Malnutrition in humans can be assessed through dietary intake studies, biochemical studies, and clinical symptoms.
Dietary Reference Intakes (DRIs) provide quantitative estimates of nutrient intakes required to prevent deficiencies and maintain optimal health.
DRIs include Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL).
RDA is calculated as EAR plus two standard deviations (SD).
Acceptable Macronutrient Distribution Ranges (AMDR) recommend the adequate intake of macronutrients for reduced risk of chronic diseases.
Food pyramid is a public educational tool to recommend daily servings of various foods.
Energy requirement in humans is maintained by calorie intake and energy expenditure.
Vegetarians have lower intake of iron, calcium, and vitamin D, but consume enough protein and less total dietary fat.
Total parenteral nutrition (TPN) is a type of exogenous nutrition provided intravenously or through tube feeding for terminally-ill patients.
Standard composition of TPN feed includes energy content, nitrogen, fat, glucose, and electrolytes, trace elements, and vitamins.
Continuous biochemical, hematological, and immunological monitoring is required for patients on TPN.
Malnutrition is measured through dietary intake studies, biochemical studies, and clinical symptoms.
DRIs include EAR, RDA, AI, and UL to prevent deficiencies and maintain optimal health.
RDA is calculated as EAR plus two standard deviations.
AMDR recommends the adequate intake of macronutrients for chronic disease prevention.
Food pyramid recommends daily servings of various foods for a healthy diet.
Energy requirement in humans is maintained by calorie intake and energy expenditure.
Vegetarians have lower intake of iron, calcium, and vitamin D but consume enough protein and less total dietary fat.
TPN is a type of exogenous nutrition for terminally-ill patients, and standard composition of TPN feed includes energy content, nitrogen, fat, glucose, and essential nutrients.
Continuous monitoring is required for patients on TPN due to individual nutritional requirements and potential complications.
