  1. Nutritional Considerations for Older Adults Tamara Deschaine, RDN, LD, CDE

  2. Objectives • Identify nutrients of concern for older adults and good sources of those nutrients • Describe adequate protein intake and good sourcesof protein • Discuss concerns with dehydration and adequate fluid intake for older adults

  3. Nutrients of Concern • Calcium and vitamin D • Vitamin B12 • Fiber • Potassium Credit:DanielVincek - stock.adobe.com

  4. Calcium and Vitamin D • Essential to maintain bone health • Vitamin D produced in response to the sun- synthesis declines with age & older adults tend to spend more time indoors, supplementation may be required • Low vitamin D results in decreased calcium storage in bones • Recommended daily intake of calcium is 1,000 mg (females) & 1,200 mg (males) • Recommended daily intake of vitamin D is 600-800 IU

  5. Sources of Calcium and Vitamin D

  6. Vitamin B12 • Required for red blood cell formation, neurologic function and DNA synthesis • Long-term use of acid-blocking medications (PPIs) may contribute to B12 deficiency; decreased absorptive capacity with age • Low B12 status associated with cognitive decline • Supplementation may be needed • Recommended daily intake is 2.4 mcg • Sources of B12 include:animal products such as meat, fish, poultry, eggs, milk and milk products, and fortified cereals

  7. Dietary Fiber • Fiber helps to lower risk for heart disease and type 2 diabetes • Keeps GI tract healthy and protects against diverticular disease and some cancers • Recommended daily intake is 22.4 grams (females) and 28 grams (males)

  8. Sources of Dietary Fiber • High fiber bran cereals • Beans (all types) • Split peas/green peas • Chickpeas and lentils • Pear/apple w/ skin • Pumpkin seeds/sunflower seeds • Avocado • Orange/banana • Berries • Chia seeds • Baked potato/sweet potato with skin • Air-popped popcorn • Almonds/pistachios/pecans/hazelnuts/peanuts • Prunes/dates/figs • Quinoa • Winter squash

  9. Potassium • May lower risk of high blood pressure and is associated with increased bone mineral density • Risk of low potassium (hypokalemia) with diuretic and laxative use • Recommended daily intake is 4,700 mg • Good sources of potassium include: baked potatoes with skin, prunes, spinach, beans, plain yogurt, fish, tomatoes/tomato juice, bananas, broccoli and cantaloupe

  10. Protein • “Nutrient of concern” according to 2015 Dietary Guidelines report • Link between low protein intake and loss of muscle mass (sarcopenia) • Protein needed to retain skeletal muscle • Loss of muscle mass decreases functional status in older adults • Recommended daily intake is at least 45 grams (females) and 60 grams (males) MedlinePlus

  11. Sources of Protein • Lean meats • Fish and seafood • Tofu/soy/edamame • Beans • Nuts/seeds • Dairy products • Protein Supplements/nutritional shakes

  12. Hydration & Fluid Needs • Risk of dehydration from decreased thirst sensation and decreased fluid intake for reasons such as problems with urinary incontinence, ambulation, manual dexterity or cognition • Loss of 2-3% of body fluid can cause physical and cognitive impairment • Signs of dehydration include dry mouth, poor skin elasticity, confusion, low BP, rapid heart rate, dark yellow urine/decreased urine output • Adequate fluid intake can decrease risk of constipation and is important for eliminating waste from the body • Fluids needs are 1.5-2 liters per day (includes fluid from foods)

  13. Conclusion • All people - especially older adults - need a variety of foods to ensure nutritional needs are met • Modify textures as neededand honor food/fluid preferences to make foods easy to eat and enjoyable • Food-based approach is ideal for meeting nutrient requirements, but supplementation may be needed (vitamins B12 and D) • Consult with a Registered Dietitian Nutritionist for guidance London Resident Magazine
