Study Notes
Geriatric Nutrition: Nutritional Requirements
-
Caloric Needs
- Decreased metabolic rate leads to lower caloric requirements in older adults.
- Typical caloric intake: 1,600 to 2,800 calories per day, depending on activity level and health status.
-
Macronutrients
-
Proteins
- Essential for muscle maintenance and immune function.
- Recommended intake: 1.0 to 1.2 grams per kg of body weight.
- Sources: Lean meats, fish, eggs, dairy, legumes, and nuts.
-
Carbohydrates
- Primary source of energy.
- Focus on complex carbohydrates (whole grains, fruits, vegetables) for fiber and nutrients.
-
Fats
- Healthy fats are important for heart health and brain function.
- Limit saturated fats; include sources of omega-3 fatty acids (e.g., fish, flaxseeds).
-
-
Micronutrients
-
Vitamins
- Vitamin D: Important for bone health; consider supplementation if sun exposure is limited.
- Vitamin B12: Absorption decreases with age; may require fortified foods or supplements.
- Folate: Vital for cell function; found in green leafy vegetables and legumes.
-
Minerals
- Calcium: Important for bone density; sources include dairy, fortified foods, and green vegetables.
- Potassium: Helps maintain healthy blood pressure; found in fruits, vegetables, and dairy.
- Iron: Essential for oxygen transport; sources include red meat, beans, and fortified cereals.
-
-
Hydration
- Increased risk of dehydration; encourage fluid intake.
- Aim for 6-8 cups of fluids daily; water, herbal teas, and broths are excellent options.
-
Digestive Health
- Fiber intake should be increased to improve bowel regularity.
- Sources: Whole grains, fruits, vegetables, and legumes.
-
Special Considerations
- Monitor for conditions affecting nutritional intake (e.g., dysphagia, dental issues).
- Individual dietary needs may vary based on chronic conditions (e.g., diabetes, heart disease).
- Consider meal frequency and portion sizes to accommodate smaller appetites.
Caloric Needs
- Older adults experience a decreased metabolic rate, leading to lower caloric requirements.
- Typical caloric intake ranges from 1,600 to 2,800 calories daily, influenced by activity level and health status.
Macronutrients
-
Proteins
- Essential for muscle maintenance and supporting immune function.
- Recommended intake is 1.0 to 1.2 grams per kg of body weight.
- Common sources include lean meats, fish, eggs, dairy, legumes, and nuts.
-
Carbohydrates
- Serve as the primary energy source.
- Emphasis on complex carbohydrates such as whole grains, fruits, and vegetables for their fiber content and nutrients.
-
Fats
- Healthy fats contribute to heart health and brain function.
- Limit saturated fats while including sources of omega-3 fatty acids like fish and flaxseeds.
Micronutrients
-
Vitamins
- Vitamin D is crucial for bone health; supplementation might be necessary if sun exposure is insufficient.
- Vitamin B12 absorption decreases with age; fortified foods or supplements may be needed.
- Folate is vital for cell function and can be found in green leafy vegetables and legumes.
-
Minerals
- Calcium is essential for maintaining bone density; found in dairy, fortified foods, and leafy greens.
- Potassium aids in maintaining healthy blood pressure levels, present in fruits, vegetables, and dairy.
- Iron is important for oxygen transport, with sources including red meat, beans, and fortified cereals.
Hydration
- Older adults are at a higher risk for dehydration; promoting fluid intake is essential.
- Daily fluid intake should aim for 6-8 cups, with options like water, herbal teas, and broths.
Digestive Health
- Increased fiber intake is recommended to enhance bowel regularity.
- Good sources of fiber include whole grains, fruits, vegetables, and legumes.
Special Considerations
- Monitor for conditions that could impact nutritional intake, such as dysphagia and dental issues.
- Dietary needs may vary depending on chronic conditions like diabetes and heart disease.
- Meal frequency and portion sizes should be adjusted to accommodate smaller appetites.
