Flashcards

Aging effect on BMR

Basal metabolic rate (BMR) decreases with age, leading to a potential increase in weight and loss of muscle mass.

Oral cavity issues

Dental problems like tooth decay and missing teeth in older adults can make it harder to chew and eat certain foods.

GI effects on aging

Digestive issues like constipation, reduced enzyme production, and impacts on nutrient absorption. This is a result of decreasing muscle tone and peristalsis, impacting digestion of proteins, etc. B12, iron and calcium absorption is also affected..

Nutrient absorption in aging

Aging affects the body's ability to absorb some nutrients, such as vitamin B12, iron, and calcium due to changes in the digestive system. It also impacts protein and other nutrient digestion as well.

Study Notes

Nutrition for Older Adults

  • Physiological changes with age affect nutrition status
  • Basal Metabolic Rate (BMR) decreases
  • Rate at which calories are burned decreases
  • Weight gain more common
  • Bone and muscle mass loss
  • Decrease in physical activity
  • Oral cavity issues: tooth decay, missing teeth, difficulty chewing fibrous foods
  • Gastrointestinal (GI) issues: increased constipation, decreased peristalsis and muscle tone, reduced hydrochloric acid production, less digestive enzymes, glucose intolerance, vitamin D synthesis decline
  • Reduced ability to absorb B12, iron, and calcium from food
  • Kidney function
  • Reduced ability to concentrate urine, Sodium clearance reduced
  • Blood pressure increases
  • Sensory losses

Changes in Nutritional Needs with Age

  • Calorie needs decrease
  • Less metabolic energy to eat as much
  • Micronutrient needs remain the same
  • Protein needs increase to 1.0-1.2 grams per kilogram per day to compensate for muscle loss
  • Fluid intake is important to prevent dehydration
  • Difficulty absorbing certain vitamins and minerals, especially vitamin B12

Nutritional Concerns and Recommendations

  • Maintain nutrient density to prevent deficiencies
  • Support digestion and absorption
  • Adaptable meal structure (small, frequent meals)
  • Adequate fluids to prevent dehydration
  • Focus on vitamins and minerals of concern (e.g., calcium, vitamin D, iron, vitamin B12)
  • Follow MyPlate recommendations for elder adults
  • Choose simple, easy-to-prepare, and affordable nutrient-dense foods
  • Consider canned foods
  • Use herbs and spices instead of salt

Frailty and Osteoporosis/Osteopenia

  • Frailty: diminished strength, endurance, and function increases vulnerability to dependency

  • Sarcopenia: Extreme loss of muscle mass, strength, and function associated with aging

  • Increasing protein intake (1.0-1.2 g/kg) important to combat muscle loss

  • Osteopenia and osteoporosis:

    • Loss of bone mass, making bones vulnerable to breaking
    • Risk factors include low body weight, petite frame, and low muscle mass
    • Nutrition therapy includes calcium, vitamin D and K2 supplementation

Other Factors and Considerations

  • Polypharmacy (using many medications) is common in older adults
  • Polypharmacy can impact nutrition by affecting appetite, taste, smell, and digestion
  • Nutrient deficiencies are common among older adults due to various factors like reduced absorption and dietary changes
  • Medications, like PPIs and statins, can affect nutrient absorption, making supplementation necessary
  • Addressing vitamin D, potassium, calcium, magnesium and other nutrient concerns is necessary for overall well-being

Goals of Nutrition Intervention

  • Create a care plan to restore/maintain health through adequate nutrition
  • Increase protein intake
  • Implement multivitamin
  • Provide foods that are convenient, affordable, and accessible to patients
  • Maintain the dignity of the patients
