1

Nutrition definition

Is the science of optimal cellular metabolism and its impact on health and disease.

2

Macronutrients

Needed in larger amounts and contain energy:
Carbs
Proteins
Fats

3

Miconutrients

Need smaller amounts:
Vitamins
Minerals

4

Kilocalorie

The amount of energy required for the body.
Eat more than required=weight gain
Eat less than required=lose weight

5

Malnutrition

Inadequate/excess intake of food
Impaired nutrient absorption
or ineffective nutrient utilization

6

Protein deficiencies

Loss of muscle mass
Inability for body to repair damaged cells
Ineffective immune functions
Edema

7

Carbohydrate deficiencies

Alter cellular metabolism
Diminish cell growth and repair
Weight loss

8

Fatty acid deficiencies

Affect cellular membranes
Disrupt retinal development
Disrupt neurotransmitter production
Disrupt brain function

24

Individual risk factors for malnutrition

-Genetics (PKU and CF)
-Lifestyle (inconsistent eating patterns)
-Conditions that affect oral intake (inability to chew or swallow)
-Conditions associated w/ impaired digestion (lactose intolerance and bowel resection)
-Conditions associated w/ impaired metabolism (CA, Parkinson's, AIDS, COPD)

25

Common diagnostic tests

Albumin
Blood glucose
Hemoglobin
Lipid profile
Electrolytes
Blood urea nitrogen
Tests to r/o anemia
Ca
P
Vit D levels
DXA scans

26

Consume fiber
Dietary supplements
Tube feedings

28

Pharmacological Agents

Weight loss meds.
