What physiological changes are associated with aging that impact nutritional status?
Physiological, psychological, and social changes
These changes affect muscle mass, bone strength, hydration, and immune function.
What are the key goals of nutrition for older adults?
Maintain muscle mass, bone strength, hydration, immune function, prevent malnutrition, chronic disease progression
These goals are crucial for promoting health in older adults.
How much lower are energy requirements for older adults compared to younger adults?
10–15% lower
This reduction necessitates a focus on nutrient-dense foods.
What is the recommended dietary intake (RDI) of protein for older adults?
1.0–1.2 g/kg/day
This can increase to 1.5 g/kg for illness or frailty.
What are the main sources of carbohydrates recommended for older adults?
High-fibre, low-GI sources
Carbohydrates should account for 45–65% of energy.
What percentage of energy should come from fats for older adults?
20–35%
Unsaturated fats, particularly omega-3, are prioritized for cognitive and heart health.
Define sarcopenia.
Progressive loss of skeletal muscle mass and strength with aging
Contributing factors include inactivity, inflammation, low protein intake, and hormonal changes.
List the prevention strategies for sarcopenia.
- 1.0–1.2 g/kg protein
- Resistance training
- Adequate energy intake
- Vitamin D sufficiency
These strategies help maintain muscle mass.
What is osteoporosis?
↓ Bone mineral density leading to fractures
It is influenced by low calcium/Vitamin D, menopause, and inactivity.
What are the prevention strategies for osteoporosis?
- 1300 mg Ca/day
- Vitamin D 15–20 µg/day
- Weight-bearing exercise
- Avoid smoking/alcohol excess
These measures help maintain bone density.
What are common causes of appetite loss in older adults?
- Isolation
- Medication
- Depression
- Sensory decline
- Dental issues
These factors can significantly affect nutritional intake.
What are the consequences of malnutrition in older adults?
- Weight loss
- Immune impairment
- Frailty
- Delayed wound healing
Malnutrition can have severe health implications.
What interventions can help address appetite loss and malnutrition?
- Small, frequent meals
- Nutrient-dense snacks
- Liquid nutrition if needed
These strategies can improve nutritional intake.
What happens to the thirst mechanism in older adults?
↓ Thirst mechanism leading to common dehydration
This requires encouragement of fluid intake.
What fluids should be encouraged to prevent dehydration in older adults?
- Water
- Milk
- Soups
Excessive caffeine and alcohol should be avoided.
List the signs of dehydration in older adults.
- Confusion
- Constipation
- UTI
- Dry mouth
- Low BP
Recognizing these signs is crucial for timely intervention.
What psychosocial factors can reduce motivation to eat in older adults?
- Isolation
- Bereavement
- Poverty
These factors can significantly impact nutritional habits.
How can mobility issues affect nutrition in older adults?
Poor food access
Mobility challenges can limit the ability to obtain nutritious food.
What support services can aid older adults in accessing nutrition?
- Meal delivery services (e.g., Meals on Wheels)
- Community centres
These services can help mitigate barriers to adequate nutrition.
True or False: Protein RDI for older adults is lower than for younger adults.
False
The protein RDI is higher for older adults to prevent sarcopenia.
Fill in the blank: The RDI for Vitamin D for older adults is _______.
15–20 µg/day
Adequate Vitamin D is essential for bone health.
What dietary implication is associated with decreased muscle mass or strength?
Increase protein intake (1.0–1.2 g/kg)
Protein is vital for muscle repair and growth, especially in individuals experiencing muscle loss.
What is the dietary recommendation for maintaining bone density?
Calcium 1300 mg + Vitamin D 15–20 µg
Calcium and Vitamin D are crucial for bone health and preventing osteoporosis.
How can decreased appetite be managed nutritionally?
Small frequent meals
This approach can help ensure adequate nutrient intake despite reduced appetite.
